GeoDASH – A New Approach to OpenGeospatial Data for Bangladesh
By : Ahasanul Hoque; GIS & Data management Specialist
As we all know the importance and varied application of geo spatial data now a days. It become the integral part from everyday lives to good governance, resource planning, risk management so on. But managing and sharing of geo spatial data are always high technical, time consuming, security dependent. Opensource GeoNode application brought an state-of-art solution in this regard, which is a platform for the management and publication of geospatial data. It brings together mature and stable open-source software projects under a consistent and easy-to-use interface allowing users, with little training, to quickly and easily share data and create interactive maps. In a nutshell, GeoNode is the application of the lessons learned from social media platforms to spatial data infrastructures. GeoNode has been customized and being used successfully by many international and national organizations as well as Governments. As part of the country’s OpenDRI to facilitate data sharing between government stakeholders, academia, and the public World Bank in Bangladesh also has established a customized geonode application called GeoDASH what has been hosted in Bangladesh Computer Council (BCC) and fully functional by government.
GeoDASH allows for integrated creation of data, metadata, and map visualizations. Each dataset in the system can be shared publicly or restricted to allow access to only specific users. Social features like user profiles and commenting and rating systems allow for the development of communities around each platform to facilitate the use, management, and quality control of the data the GeoDASH instance contains.
At its core, GeoDASH is based on open source components GeoServer, GeoNetwork, Django, and GeoExt. These provide a platform for sophisticated web browser spatial visualization and analysis. Atop this stack, the project has built a map composer and viewer, tools for analysis, and reporting tools. GeoDASH also supports facilities for styling data as well as collaborative features like ratings, comments, and tagging for data, maps, and styles. GeoDASH is built on four key tenets: Collaboration, Distribution, Cartography and Data Collection. To promote collaboration, GeoDASH is designed on Web 2.0 principles to:
- Make it extremely simple to share data
- Provide user statistics
- Easily add comments, ratings, tags
- Allow collaborative filtering
- Provide rankings of best ‘views’ and data sets contributed o Highest rated, most viewed, most shared
- Allow connectivity between several GeoDASH instances to augment the collaborative potential of government GIS databases.
Simply put, users will be able to comment and rate data; these ratings will influence search results, much the same way that YouTube uses user feedback to promote quality works. To allow for more institutional oversight, GeoDASH will also all participating groups to endorse data. Endorsement provides a “lightweight” way for organizations to provide official guarantees on data without stifling unofficial but productive crowd-sourced data collection, neo-geography, and amateur cartography.
A good amount of data has already been collated, and it is envisioned that in the near future, GeoDASH will include further information and visualization to the platform from various global and in-country sources, expanding institutional commitments to open data, supporting community mapping activities, and developing decision support tools that leverage open data to assist the Government of Bangladesh with contingency, planning and management activities. We do hope you can share your or your institution’s datasets on the GeoDASH portal to enable others to benefit from this work. Please join the GeoDASH Bangladesh community group for getting updates and sharing your issues and comments too.
HOT supports the collaborative map for emergency response while any disaster strike anywhere in the world. With time HOT has been speeding its wings in humanitarian arena from community development, partnering with different agencies, technical tools and platform development. Like the great collaborative mapping project tool Tasking manger HOT also developed HOT Training center under which HOT has developed a curriculum for its volunteer ‘Activators’; specifically a protocol and training program to empower those people who coordinate our Disaster Mapping. Key roles were identified during initial development and observation of the Nepal Activation. The HOTActivationProtocol.pdf and the bulk of the raw training material was drafted through an ‘Activation Sprint’ workshop of core HOT coordinators in Washington DC, 27-29 April 2015. The curriculum was then further developed by specialist, Russell Deffner, under the supervision of Technical Project Manager, Mhairi O’Hara; with community input and direct involvement of existing HOT Activators and the Activation Working Group.
we from Bangladesh
After the first workshop for the HOT Activation Curriculum what was held during the pre-conference events of the first Africa Open Data Conference. Hosted by the World Bank and the United Republic of Tanzania in the capital city, Dar Es Salaam, the second workshop of HOT Activation was held in Jakarta, Indonesia where I attended. With state of the art arrangement Russel Deffner and Mhairi O’Hara conducted the three days sessions. I (Ahasanul Hoque) and Sajjad Hossen attended the Humanitarian OpenStreetMap Team (HOT)Activation Workshop with other participants from Nepal, Philipine, Indonesia. Total we were 11 participants started at 9am in 18 September at Meeting room of ibis Tamarin ,Jakarta Hotel. After ice breaking and introducing session of MHairi , Russel had started with the presentation for inception, introducing activation protocol, 3 phases, event size determination, roles, essential courses, attending procedure, getting badges etc. After that each us chosen one course to complete by answering the multiple choice questions after reviewing the given materials and related links. Second day we chosen another course like before and all these course are actually connected with roles for simulation exercise as well as real life disaster events activation. And finally we all chosen different roles for simulation exercise where Manning Samble was acting as Activation Lead, myself Imagery, Sajjad Tasking Manager, Faysal-Public Relation, Vasanti-Community Care, Megha-Data, Pratik-Partner Liasion, Yantisa – Usability, Harry- Reporting. All of us performed their own role nicely with demo mail threads what gave us the feeling of a real activation.
Overall I would say the goal of HOT and the activation workshop was fulfilled, means they are successful to share the knowledge of activation roles to the mappers what build the capacity of the participants for future disaster events. From my point of view the curriculum was perfect for the participants , it will bulild the number of volunteers- that’s fine but for better going the martials should be delivered at least 1 week prior to the workshop. Another point I should mention that from the simulation exercise we realized that before taking any role the persons’ background and skill matters. I think the sequence of the course materials is perfect, self-explaining, some questions’ need to re-word for getting the actual meaning by participants. The biggest convenience is the training courses are openly available for everyone to access online, So I would complete the remaining very soon and have an wish to spread this training among the mappers as OSM in Bangladesh.
I shouldn’t skip the fun part of the workshop, the trainers didn’t occupy the days with courses only but also the HOT dinner, visit to the national monument (Monas), tour in car free day etc. The variety of food was really wondering as well as tasty. To me the item Kedai Pelangi (beef ribs bbq) was the best followed by chicken saute. Finally, the restaurant GARUDA, extraordinary and artistic; whoever is visiting Jakarta they should taste the food I Garuda. Our old Jakarta visit was also fun, visiting museum, different street show, shopping from street fair, lemur show and the overall crowd gave me the feelings of unity. I love the people, I love Jakarta.

As a disaster manager or GIS and remotesensing expert you will easily accept how much it is difficult to collect, manage the remote sensing data (either aerialmaps or satellite images), during emergency. These remote sensing data is valuable in detecting and mapping many types of natural hazards when, as is often the case, detailed descriptions of their effects do not exist. If susceptibility to natural hazards can be identified in the early stages of an integrated development planning study, measures can be introduced to reduce the social and economic impacts of potential disasters. The good news is OpenAerialMap(OAM) brining a solution to this for disaster manager or humanitarian mapping communities arround the world. OAM is a set of tools for searching, sharing, and using openly licensed satellite and unmanned aerial vehicle (UAV)/ drone imagery. OAM is a browser for openly licensed satellite and drone imagery. Disaster response organizations like Humanitarian OpenStreetMap Team and satellite companies like Astro Digital have contributed thousands of overhead images from around the world. OpenAerialMap infrastructure will be extended to make it easier for individuals and communities to use, from the drone hobbyist with imagery to share, to the community worker who wants to analyze and annotate public areas in need of improvements. From many perspective OAM is better than the WMS which is a common standard for mapping service but bit old and useful for small area where OAM
Can access to larger areas – In general, WMS services limit request sizes to smaller than a certain area. This limit can be impractical for users who need to produce images for reports or other similar offline use.
It can be used offline – One of the canonical use cases for OAM-style imagery is for use in disaster situations. In those situations, access to an ‘online’ API is inappropriate due to poor internet connectivity, and downloading data is neccesary. WMS does not make this possible.
Possible mosaicing – In general, when delivering output data as JPEG, mosaicing responses from multiple services together is hard or impossible.
The primary purpose for not making OAM host imagery products/access tools itself is to help eliminate bottlenecks in mission-critical services by allowing them to be replicated in the places they’re needed most.
The key to this approach is to make each step of the process as simple as possible; that way, there is very little that can’t be replicated or replaced easily, and there are no complex moving parts that require significant maintenance. The key parts of such an infrastructure are:
- Imagery Index – a readily accessible way of finding information about imagery that is available and how to access it.
- Storage – A distributed set of resources through which imagery can be made available for access by OAM tools.
- Access Tools – Tools which use the Index and access data from Storage to build output that users of the OAM data will want. This includes everything from a WMS to a set of tiles that can be made available offline.
The imagery index is the core of the OpenAerialMap project. It acts as a clearinghouse for the OpenAerialMap imagery data. The core object in the imagery index is an License API. There are two types of images – an Archive image, and a Processed image.
- Archive Image: This is designed to be metadata about a file which has not been processed for OAM, but which could be processed either by tools or by a human. This might mean that the imagery is only available in a compressed format, or is in an unusual projection. Generally speaking, this is the case for imagery provided over the web by most government agencies.
- Processed Image: A processed image is an image which has been specifically created for OAM, or fits the needs of an OAM client well. For more details, plz visit OpenAerialMap Archive Image.
The concept behind the storage layer is:
- Use simple, existing technologies
- Search out friendly patrons in the short term, and investigate more complete solutions in the long term
- Treat the URL/HTTP access as the primary way to find information, and don’t tie storage to any aspect of the catalog directly. For more, plz visit Storage.
And the area of OAM that has the most room for experimentation is access tools, or other tools for building products out of the Imagery Index.
OAM was available at http://openaerialmap.org/ between November 2007 and December 2008. HOT were working to relaunch OpenAerialMap and have been award a Humanitarian Innovation Fund grant to DevelopmentSeed that has launched OAM Beta version
Currently OAM has imagery from the Nepal earthquake response, high resolution satellite imagery of Finland, agriculture imageryover Nebraska, and drone imagery from Vanuatu.
Definitely OAM is a great tool and stress remover for disaster data handlers arround the world but still it has to go a long way to develop the system more and make this great initiative it running. From my side OAM have to look in-
1. Image availability for whole world
2. Image quality – Spatial resolution and contrast
3. Scale of the image
4. Temporal resolution of the image
In 2004 one man set out with a bicycle and a GPS recorder. Back then creating a map of the world from scratch seemed crazy to many people, but even so, people joined the effort. A few people at first, but 10 years later OpenStreetMap has grown to a global community with over 1.7 million registered members, with around 3,000 members editing the map every day. This map built by hundreds of thousands of people what is now used for serious work: for example Médecins Sans Frontières works with OpenStreetMap to help its doctors in West Africa keep track of the current ebola outbreak. 25 million miles of roads in every country in the world have been mapped. Here is a look back (developed by mapbox.com) at how the most detailed map of the world started.

Good news for OpenStreetMap: the main website now has A-to-B routing (directions) built in to the homepage! This will be huge for the OSM project. Kudos to Richard Fairhurst and everyone who helped get this up and running.
You might be thinking, “Why would this be huge? Isn’t it just a feature that other map websites have had for years now?” Well, the first thing to note is that the philosophy of OpenStreetMap is not to offer a one-stop-shop on our main website, but to create truly open data to empower others to do great things with it. So there has already been fantastic OSM-based travel routing for many years, on excellent websites such as OSRM, Mapquest, Graphhopper, Cyclestreets, Komoot, cycle.travel… the list goes on and on.
But that’s not what makes it huge.
What makes it huge is the difference it will make to OpenStreetMap’s data by creating a virtuous feedback loop. One of the main reasons we show a “slippy map” on the OpenStreetMap homepage is because people can look at it, see a bridge that needs naming or a building to add, click “Edit” and fix it straight away. That feedback loop is what allowed OpenStreetMap to build up what is now the most complete map of many regions around the world.
But we have a saying: “what gets rendered, gets mapped” – meaning that often you don’t notice a bit of data that needs tweaking unless it actually shows up on the map image. Lots of things aren’t shown on our default rendering, so the feedback loop offers less incentive for people to get them correct. And that goes doubly for things that you never “see” on the map – subtle things like “no left turn” at a particular junction, or “busses only” access on a tiny bit of road, or tricky data issues like when a footpath doesn’t quite join a road that it should join on to. Now that people can see a recommended route directly on the OSM homepage, they have an incentive to quickly pop in and fix little issues like that. The end effect will be OSM’s data going up one more level in terms of its quality for routing. This will empower everyone to do great things with geographic data and getting from A to B.
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean. The first submarine communications cables, laid in the 1850s, carried telegraphy traffic. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fibertechnology to carry digital data, which includes telephone, Internet and private data traffic.
Modern cables are typically 69 millimetres (2.7 in) in diameter and weigh around 10 kilograms per metre (7 lb/ft), although thinner and lighter cables are used for deep-water sections. As of 2010, submarine cables link all the world’s continentsexcept Antarctica.
TeleGeography’s Submarine Cable Map has been updated for 2015. The latest edition depicts 299 cable systems that are currently active, under construction, or expected to be fully-funded by the end of 2015.
This year’s map pays tribute to the pioneering mapmakers of the Age of Discovery, incorporating elements of medieval and renaissance cartography. In addition to serving as navigational aids, maps from this era were highly sought-after works of art, often adorned with fanciful illustrations of real and imagined dangers at sea. Such embellishments largely disappeared in the early 1600s, pushing modern map design into a purely functional direction.
To bring back the lost aesthetic that vanished along with these whimsical details, TeleGeography referenced a variety of resources in the design process. One of the most invaluable was Chet Van Duzer’s Sea Monsters in Medieval and Renaissance Maps book, which provides arguably the most complete history of the evolution of sea monsters and map design from this period. Our final product is a view of the global submarine cable network seen through the lens of a bygone era.
The map depicts routes of 278 in-service and 21 planned undersea cables. Capital cities for each country are also provided.
The map provides latency from the United States, United Kingdom, and Hong Kong to several other countries, presented in milliseconds of round trip delay.
Inset infographics provide lit capacity data from 2002-2013 for the trans-Atlantic, trans-Pacific, US-Latin America, and Europe-Asia via Egypt routes.
Inset illustrations depict steps in the cable laying process, including the receiving of a submarine cable on shore and the coiling of cable within a ship’s tank.
Dangers to Cables
The map is adorned with images of common causes of cable faults, including fishing vessels, anchors, and trenches on the ocean floor, as well as cable maintenance vessels responsible for repairs. In homage to vintage maps, it also includes ornate illustrations of mythical sea monsters.
The map is printed on Yupo, a high quality synthetic material, and measures 36” x 50” (0.9144 m x 1.27 m). The map is available flat and shipped in a tube (recommended for framing or hanging on a wall) or folded (for more convenient storage and transportation). Heat mounting is not recommended.
What is crowd-sourcing?
Crowdsourcing is generating content on the internet, which involves contributions from a large, disparate group of individuals. These methods rely upon web applications that allow people to upload information easily and allow many others to view and react to this information. Crowdsourcing relies on the principle that a lot of knowledge resides with individual citizens, who are experts of their own local environment. Mapping sites that utilize crowdsourcing include: OpenStreetMap project, Google Map Maker, Geo-wiki, andWikimapia. These tools vary in terms of scope of geographical coverage, data entry methods, targeted end-users, data licensing arrangements, and ease of use. Additionally, they may use different methods of moderating data (verifying that entered data is valid), which influences data quality and speed of publication.
What is crowd source Mapping?
A vast amount of geodata is available on the internet, through on-line maps, web services and virtual globes. Data providers range from the individual mapper enthusiasts to geo-information professionals. Base data, such as road networks and satellite imagery are made available on a global scale, and more specific and valuable thematic data is often produced within dedicated projects.
Current software applications are changing the web to act more and more as platform for real-time information integration, with many web sites collaboratively controlled. Geospacial applications range from personal mash-ups, which is the combination of data from two or more sources, to project-based web mapping, where the concept of location adds new possibilities for exploring information.
Why should you map?
Quality geographic data helps empower organizations and communities to make important decisions across a range of environmental, economic and crisis management themes. For many places in the world, this information is incomplete or does not exist at all. Digital humanitarians map online to help give others the data they need to build a more sustainable future.
Through the Open Data Commons Open Database License 1.0, OpenStreetMap (OSM) contributors own, modify and share data publicly. There are many other free maps on the Internet, but most have legal or technical restrictions preventing others from using the data openly. With OSM both the maps and underlying data can be downloaded for free, for developers or anyone to use or redistribute. Additionally, in many places of the world where there is no commercial motivation to develop this data, OSM is often the best available resource.
How to Select&Edit a Task in the OpenStreetMap Tasking Manager
Select a Task and map a tile. You do not need to be at the location and do not need to know the names of roads and buildings. You will look at satellite imagery and trace roads, paths, buildings and areas
- Select the Task you wish to work on; a new browser tab or window (depends on browser settings) opens, taking you directly to the mapping task on the OpenStreetMap Tasking Manager website.
- Log in with your OpenStreetMap account. If you are still logged into OpenStreetMap, you will not need to enter your login info.
- You will see a map and information about the task including instructions on what to map.
- Select a tile to work on.
- Use the interactive map and zoom in on the highlighted tiles. The job has been broken up into small tile areas of the map to allow you to do a little bit of mapping rather than trying to map the entire area. This also lets other simultaneously map other tiles, or areas.
- When you select a tile, your task is to map that specific tile by tracing satellite imagery.
- Gray tiles represent all of the tasks available in this job. Red tiles are areas that have been marked as done. Green tiles are areas that were marked as done and have been validated. Gray tiles with yellow outlines are areas that are currently being worked on.
- Click on a gray tile to select it. The task tab opens. Click on the green button that says, “Yes, I want to work on this task”. By selecting a tile you are “checking it out”. No one else will be able to edit this tile while you are working on it. Once you have completed working on the tile you will need to “check it back in” so others can validate or build on your work. The “check in” process is explained later in these instructions.
- The task tab has a few additional sections: extra instructions (information about the imagery you are about to work with. In some cases, you will need to adjust the imagery in the iD editor), information on how to credit your edits (what you will copy and paste into the iD editor so your edits can be logged correctly) and history of this task.
- To work on your tile, select iD from the editing tool options. This opens a new tab or window in your browser.
- If needed, adjust the satellite imagery to match with an existing map edit by:
- clicking on the layers button
- scrolling down to “fix alignment”
- using arrow buttons to line up the high resolution satellite imagery with the existing map edit. You may need to zoom in to do this.
- Add roads, paths, buildings and areas in your tile. When you make a map edit, a dialogue box will appear. As you trace, you may not know the specific name of the road or building, which is okay. For instance, when you select the “Building” button in the iD editor, your map edit is automatically tagged as a building.
- Credit your work each time you save your edits. A collection of map edits are called a changeset, and when you save your edits, you are essentially applying a “commit” to the OSM database. The iD editor will ask if you want to provide a “commit message” to your collection of edits. This information will help us understand when an edit was made as part of MapGive.
- To credit your edits:
- Click back to the OpenStreetMap tasking manger browser tab.
- Scroll down to the credit section in the task tab.
- Copy the credit. Click back on the iD editor browser tab.
- Paste the credit in the tag section of the dialogue box.
- When you finish or wish to stop mapping a tile, return to the OpenStreetMap tasking manager.
- Either “unlock the task” or “mark it as done.” Unlocking the task means that you have done some of the map edits but there are more to do. Marking the task as done means that you have completed the tile.
- When you unlock a task, the tasking manager allows you to input comments. You may indicate how much of the tile is complete and specific features that need work. If you have no comments, write “no comments”.
- TIP: Unlocking a task = “checking it back in”
- If you saved your edits in the iD editor, they will still be there others or for you to come back to.
- Thank you for learning how to map and also for mapping to make a difference.

How to Map in OpenStreetMap
1. Overview of OpenStreetMap
- Log in to OpenStreetMap.
- Try out the map controls on the right side of the screen. You may zoom in, zoom out and view your current location. Select between layers, view the map key, share the map and make comments.
- Try out the search OpenStreetMap function on the left side of the screen. Search for any location; type in any location to load a map of that area.
- Use the zoom in button on the right of the screen to examine the map closely. Depending on where you’ve selected, you should be able to see the three main elements of OpenStreetMap:points, lines and areas.
2. How to Edit in OpenStreetMap
- To create points, lines and areas in OpenstreetMap, click the drop down arrow next to the wordEdit. Select the option Edit with iD (in browser editor.)
- The iD editor opens by showing you the location you previously selected.
- At the top of the iD editor are the main controls. Select an action to perform: map a point, line or an area. The buttons to go back, forward and save are also at the top.
- By clicking save after making an edit to OpenStreetMap, your changes go live to the entire world. Save often!
- Use the dialogue box to the left of the map to input information about the points, lines, and areas that you map. You do not need to know the name of the place, road or area. Just marking it on the map is very helpful for others who can add in details.
- To the right of the map, there is a help button and the option to walkthrough the process of editing in OpenStreetMap. You may have completed the walkthrough previously. If not, take the walkthrough to become familiar with the elements of the iD OpenStreetMap editor and how to view buildings, roads and areas on satellite imagery.
- Select an area to start practice mapping
- Select an area with little existing map data – not a major city or heavily developed area. Type the location you’d like to practice mapping into the search box and click go. A map of the area you selected appears.
Map a Point
To map a point in the OpenStreetMap iD editor:
- Select the Point button in the top left of the map. It will turn blue to let you know that it’s been selected. Then click a position in the map where there is a building or area that you’d like to define.
- A Node icon appears. (Wikipedia defines a node as: “One of the core elements in the OpenStreetMap data model. It consists of a single point in space defined by its latitude, longitude and node id.”)
- The Set feature type /Set feature type dialog box also appears to the left of the map with a series of descriptive inputs. If you know the name of the building or area, or additional details, enter them here.
- Once you’ve finished adding details connected to the node, close the dialog box by clicking on the X to the right of Edit Feature at the top.
- To edit the node again, click on it again and the dialog box will reopen.
- To delete a node that is incorrect, or created by mistake, click on node. A trashcan icon appears next to it. Click on the trashcan to remove the node.
- If you ever need to step back a few edits, click the back arrow icon at the top of the editor. You can allow step forward a few edits with the forward arrow icon.
- Click save at the top of the editor to make sure your edits are logged into the OpenStreetMap database.
Map a Line
To map a line in the OpenStreetMap iD editor:
- Click the Line button at the top of the iD OpenStreetMap editor. It turns blue to indicate it is selected.
- Click on a position on the map. A dot appears connected to a line.
- Click on another other point on the map; another dot appears and the line will connect those two points.
- Draw more points to establish the line or, click the Esc escape button on your keyboard to finish drawing the line.
- The line then glows red to let you know that it has been created and a dialog box opens up to the left of the map editor.
- Specify whether the line is a road, path, river or other options.
- You may be specific or general depending on the satellite picture.
- To modify a line that has already been created, click on it. The dialog box reopens next to the editor along with the trashcan icon next to the line.
- Always remember to hit save at the top of the editor so your edits are logged into the OpenStreetMap database.
Map an Area
An area can be a park, a building, a lake, a forest or other types of enclosed filled land. To map an area in the OpenStreetMap iD editor:
- Click on the area button at the top of the editor. It turns blue to let you know that you’ve selected it.
- Select the edges of the building or land you want to define. Just click on the corners and the editor will fill in the space between.
- Once you’ve fully outlined what you want, double click on the last created point to complete the area. The area will turn red to let you know that it’s been created.
- A dialog box will appear next to the map editor and allow you to classify the area you’ve just defined. There are numerous options and you may be as general or specific as possible.
- If you do not know the specific name of the area, leave this section blank. Just label what you can see from the satellite imagery — such as a “lake” or “building”.
- Click save at the top of the editor to make sure your edits are logged into the OpenStreetMap database.
- Once you hit save your edits are live and part of the OpenStreetMap data and immediately available to anyone in the world.
- Take some time to practice what you’ve just learned. Once you feel confident in your ability to map, continue.
