Crowd-Sourced Mapping !!!

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.

OpenStreetMap !!!!

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.

Learn OSM: Part-3 (Task Manager)

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.
  • Walkthrough
  • 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.

Valentine Blog by GIS Expert

It was valentine day few days before. What a GIS geek did that day, they played with heart, heart shaped map. Heart shaped map projections are known as cordiform map projections which is derived from the Latin “for” for heart and form for shape. In honor of Valentine’s Day, here’s a look at two heart-shaped map projections.

Werner Map Projection

The Werner map projection is a heart-shaped map projection originally conceived by Austrian mathematics professor Johannes Stabius (Stab) of Vienna around 1500.  Johannes Werner, a German priest from Nuremberg expanded on the projection which he described in his book Nova translatio primi libri geographiaae C. Ptolemaei published in 1514.  During the 16th and first part of the 17th century, the projection was used for world maps and some continental maps.  Cartographers  Mercator, Oronce Fine, and Ortelius used the projection in the late 16th century for maps of Asia and Africa.  During the 18th century, the projection was replaced by the Bonne map projection which is also cordiform.  Also known as the Stabius-Werner (or Stab-Werner) projection, this projection is pseudoconic equal area.

Although the beginnings of this cordiform map projection has its origins in Ptolemy’s early works, the development of a heart shaped map projection during the renaissance era is not a coincidence.  The symbology of the world as a heart was closely tied to the concept of the inner emotions affecting the physical world (Brotton, 2013).

World map created in 1514 by Oronce Fine (1494–1555) who was one of the first French scholars to work with cartography.


Bonne Map Projection

Although named for French cartographer Rigobert Bonne who lived in the 18 century, the Bonne map projection had been in use since the early 1500s.  Like the Werner projection, this heart-shaped map projection is also pseudoconical equal-area.

This 1511 World map by Bernard Sylvanus is one of the earliest known two-color cartographic works.


Say ‘I Love You’ with your GPS

Are you a GIS geek? Do you like to play with your GPS or location/gps apps of your phone? Then lets play with that for expressing your love. You can express your love in an unique way, you might consider using your GPS and your favorite mapping application. In this Valentine let me tell you some GPS love stories shared by Morais:

Aspiring Romeos around the world have been employing their GPS tools in order to give a voice to their valentines. In 2013, Payam Rajabi decided to show how much he cared about his girlfriend, Clare, by carefully etching a heart shape onto a city map of San Francisco using his iPhone and bike. By tracking himself with his GPS while he rode, Payam inscribed his message of love while covering 27 miles and burning over 1100 calories in 2 ½ hours.

Payam and Clare were in a long-distance relationship ever since he had to move from Toronto to San Francisco. Of course, Payam had to include an elevation map of his ride, demonstrating the depth of his love as he pumped over the many hills of San Francisco. Rajabi got more out of his ordeal than just the admiration of Clare, however. He was ultimately featured in a short commercial from Verizon.

His ride inspired other romantic gestures. The Verizon commercial encouraged a man named Gary to take the idea one step further and propose to his girlfriend, Lorinda, via a GPS message using the popular Endomondo fitness application. Gary had wanted to propose for her birthday and spent a couple weeks scouting the local area for the perfect spot. The original idea was to run the route but he went with his bike instead.

In the end, Gary took the afternoon off work, rode the proposal workout, and met his girlfriend for dinner. While the two were together, Gary shared that he had gone for a bike ride and asked Lorinda to look at his ride by sharing the link to his workout. The map spelled out “Lorinda, will you marry me?” After the initial surprise, her response was, “of course” which she then mapped out herself using her own GPS.

Endomondo is not the only mapping application that has been used to propose geographically. Murphy Mack also used his bike to map out the words “marry me Emily” using Strava, a free software that cyclists like to record their routes, elevation, and speed. Like Payam, Mack rode out his proposal on the streets of San Francisco. His route covered 18 miles, took 80 minutes, and burned about 750 calories. Mack not only proposed but surrounded the words with a heart.

Murphy Mack used his bike and GPS to propose to his girlfriend.


While Murphy’s proposal takes Payam’s heart to another level, the ultimate GPS tracking gesture of love might belong to the Japanese artist Yasushi Takahashi, also known as Yassan. In 2010, Yassan journeyed across the entire country in order to propose to his girlfriend. During the six months it took him, Yassan covered over 7,100 kilometers (about 4400 miles) mostly by walking but also using a car, bicycle, and ferry.

When Yassan arrived back at home, he plotted his route onto Google Maps, spelling out “marry me” over the large island of Honshu and a heart with an arrow through it over Hokkaido. Yassan’s marriage proposal has been certified by the Guinness Book of the World Records as the world’s largest GPS drawing. His journey was also featured in an ad campaign and a documentary series by Hi-Tec, a producer of hiking boots and shoes called Walkumentary.

Generating artistic drawings using GPS tracking devices goes far beyond just messages of love for Valentine’s Day, however. Yassan quit his job in 2008 to pursue his passion for large-scale GPS images. Some of his other creations have included his own name, the words “still the one,” and drawings of mascots. In 2014, Jeremy Wood drove over 10,000 miles across the United Kingdom to draw a GPS image for Halloween. The picture included a pumpkin in a witch’s hat, a spider web, ghosts and bats with the word “Halloween” underneath.

GPS Drawing !!!

The GPS Drawing Project seeks to display GPS-based artistry created by navigating through a landscape with a GPS unit. The resulting linear trail collected by the GPS Data Logger creates the resulting art. There is a gallery of the GPS art that the user can browse through. Each entry contains an interactive shockwave called “GPS-o-shockwave” of the GPS route as well as a description of the area the artist navigated. The entry entitled “The Brighton Elephant” gives a good perspective of GPS art. Accompanying the GPS drawing is an aerial of the area navigated with the route overlaid. The art isn’t just restricted to land. Also listed in the GPS Gallery are drawings obtained by sea and by air. Most of the submittals appear to be from England, but there is also GPS art from points in Thailand, China, and South Korea.

i00043 - Copy













The submittal of GPS art is open to anyone. Ascii files of the GPS points are welcome to be submitted to the site. There is also a shockwave application where you can copy and paste your GPS data points to see what your GPS-based art looks like. Still exploring for ideas on using your GPS unit? There’s a GPS Games Developer Forum at Yahoo! You can also visit the GPS Games web site for more ideas.

Lets do some fun using GPS !!!

If you’re looking for something new to do that will get you outdoors, use your smartphone and get involved in some great activities, you’ve probably considered playing some sort of GPS game.

i00043 - Copy

Since there are so many fun outdoor games to choose from, many of which have very similar names, it can get a little confusing. So, we’ve made a list of some of the best GPS games for you to try out. It’s time to get stuck into some geohashing, geocaching, geodashing and a number of other games that have more than two letters different in their names.

1. Tourality

Tourality is a smartphone GPS game which has you running all over your area. You choose exactly which sort of game you’re playing in advance, then Tourality does the rest. The application will lead you to the each location in turn, so all you have to do is run!

gps games

2. Geocaching (& Travel Bugs)

Geocaches are hidden packages which are mapped for people to find. Inside the packages are useful bits and pieces people have left behind, often with a book you can sign to say you’ve been there. Usually you are free to take something from the cache and replace it with something new for someone else. Head to a major geocaching site or get a geocaching application for your smartphone to find out where your nearest caches are.

Travel bugs and geocoins are objects with barcodes and/or serial numbers attached, usually with some sort of instructions as to where you want them to go. You leave them in a geocache and when someone finds them they read your instructions and take them to the next logical cache. The bugs are tracked via sites like so you can map the journey your bugs take.

3. Geohashing

Geohashing is an XKCD invention, thanks to a random comic that triggered the real life game. The nature of the geohash is such that for each day there is a new hash for every graticule (that is, the area inside four confluences). There’s a wiki of people geohashing worldwide, plus plenty of geohashing apps for smartphones and the web which you can use to get the co-ordinates for the day’s geohash adventure.

4. GPS Mission

Pick a GPS mission and get out there! You’ll be sent on a scavenger hunt adventure to reach destinations and answer questions. Users can create their own missions for the site, involving locations of local buildings and historical sites.

games for gps

5. Geodashing

Geodashing is a game where a number of random locations are chosen for each game, then the winner is the person or team who visits the most locations before the deadline. As you might imagine, online teamwork is encouraged as the locations are worldwide. Head to thegeodashing site to start playing.

6. Make Your Own Treasure Hunt

Using Locomatrix’s Treasure Hunt game, you can design a treasure hunt using photos. The application will use your GSP to determine how close you are and tell you if you’re getting closer to it or not. This is a good one for parents to prepare for a family outing. If you’re lucky someone may have already created a treasure hunt for your area. Locomatrix also have other games designed to use GPS to bring computer games back outside, so check them out too.

gps game ideas

7. Waymarking

Waymarking is a way to share the co-ordinates and details of interesting locations in order to build a community map of cool places. From this, you can take part in scavenger hunts using your smartphone and the waymarks near you.

gps games

8. Repurpose Outdoor Games With A GEO Twist
Try playing capture the castle, where the “flag” is a GPS co-ordinate which you then have to reach in order to win. See more ideas similar to this here.

9. Confluence Project

Confluences are the points where longitude and latitude lines meet, so naturally there is a website dedicated to seeing what each and every confluence looks like. Head to your nearest confluence using your smartphone’s GPS to guide you, take a photo and stick it to take part.

10. Make Your Own Geocaching Game

Either use the cache to point the way to the next co-ordinates or use a stamp or sticker system within caches to fill out a passport of locations which have been found.

ArcGIS 10.3: The Next Generation GIS

Esri recently announced the release of ArcGIS 10.3.  Brian Peterson and Robby Deming from Esri provide some insights in what the latest release of ArcGIS brings.  

At version 10.3, ArcGIS continues to innovate and push the science of geography and GIS. This release includes a series of new apps and enhancements that helps people discover, make, use, and share maps from any device, anywhere, at any time.

ArcGIS 10.3 includes new apps and enhancements that will boost your efficiency and extend the impact of your work in your organization. Here are some of the highlights:

ArcGIS Pro – Your New ArcGIS for Desktop App

ArcGIS Pro reinvents desktop GIS. This brand new 64-bit desktop app lets you render and process your data faster than ever. With ArcGIS Pro, you can design and edit in 2D and 3D, work with multiple displays and layouts, and publish maps directly to ArcGIS Online or Portal for ArcGIS, making them available on any device.

ArcGIS Pro is currently in prerelease and will be available to you as part of your ArcGIS 10.3 for Desktop license. Stay tuned for the final release in January.

More Tools for ArcMap

At 10.3, ArcMap is better than ever, with improvements such as new analysis and automation tools, infographics capabilities, and tools for managing your data more efficiently. You can even run any version of ArcMap side by side with ArcGIS Pro.

ArcGIS for Server is now a complete Web GIS

ArcGIS Online provides Web GIS, hosted by Esri. With ArcGIS 10.3, ArcGIS for Server delivers Web GIS in your own infrastructure. This is possible because ArcGIS for Server Standard or Advanced now entitles you to Portal for ArcGIS. Portal for ArcGIS unlocks the full suite of ArcGIS apps, including the new Web AppBuilder, so everyone in your organization can leverage your GIS work.

ArcGIS Online continues to add new capabilities

Read about the Q4 update to ArcGIS Online.

3D begins to roll out across the entire platform

We are continuing to realize the vision of taking 3D information and bringing it to life in browsers and applications that run on devices. At 10.3, we’re delivering a whole new 3D editing and visualization experience for the Desktop with the introduction of ArcGIS Pro. What’s more, you can share the 3D scenes you create in ArcGIS Pro with anyone using ArcGIS Online, which now includes a new Web Scene Viewer. A web scene can have layers, including elevation layers, imagery layers, tiled layers, and feature layers. In addition to viewing scenes created and published using ArcGIS Pro, the ArcGIS Online Web Scene viewer can also be used to create 3D Scenes by mashing up existing layers in your Web GIS, right from your browser. Content that you have already captured can be brought into these scenes and displayed so users can work with that information in 3D.

Over the next few months, subsequent releases will deliver even more 3D capabilities including the ability to publish and disseminate web scenes and layers using your own ArcGIS Servers, including support for sharing photo realistic 3D models (such as detailed buildings), and 3D-enabled mobile applications that work on devices, such as tablets and smartphones.

Real-time GIS at 10.3

At 10.3, real-time, streaming data is fully integrated into ArcGIS. The GeoEvent Extension for Server delivers improved performance with increased throughput capability, faster spatial filtering, and the ability to scale-out by adding machines to a cluster.

A suite of new spatial operators have been added to GeoEvent for even more powerful spatial filtering options, such as intersect, touches, and overlaps, all of which can be applied to any or all GeoFences.

New spatial processors are included, such as Buffer CreatorIntersector, and Symmetric Difference, delivering an unprecedented array of real-time spatial analytics. Even more real-time spatial processors are available in the Esri Gallery on GitHub. You can even create your own.

At ArcGIS 10.3, real-time web maps are here thanks to the introduction of the Stream Service and Stream Layer. Now, real-time layers can be configured, symbolized, and filtered directly in a web map and added to ArcGIS apps and custom applications.

More opportunities for developers

There are different aspects to developing with the ArcGIS platform, and 10.3 introduces new capabilities for developers across the board. First, web development gets better, more powerful, and easier with enhanced APIs, new layers for working with information such as real-time that is streamed into browsers, new visualization capabilities for working with these layers, and new functionality for working with proportional symbols and performing dot density mapping. All of this is available in the JavaScript API and in our web GIS developer model.

Another area that is new in 10.3 is the introduction of Web AppBuilder for ArcGIS, which not only allows users who are not developers to assemble applications, but also gives developers opportunities to build their own widgets that can be used with Web AppBuilder.

10.3 marks the beginning of a wave of releases that will further help developers build mobile applications using ArcGIS Runtime. This will allow developers to take advantage of the same technology that Esri uses to build our mobile applications including CollectorExplorer, andOperations Dashboard. These releases will expose the new 10.3 capabilities for working with 3D, real time, mapping, and offline to developers building native applications for the different mobile platforms.

Last but not least, developers working with ArcGIS Pro can leverage Python to automate tasks. Developers will also be able to extend ArcGIS Pro with add-ins using the ArcGIS Pro SDK for .NET. This will be available in beta during the first quarter of 201.
