OpenStreetMap and GeoGit for Yolanda Recovering

We’ve had several opportunities to refine GeoGit workflows in real-world situations, but among the most fulfilling was assisting with the response to Typhoon Yolanda (also known as Typhoon Haiyan) in the Philippines. It was the strongest cyclone to make landfall in recorded history, resulting in an urgent need to share data about the damage to […]

Map: A big matter now a days

A map is a visual representation of an area – symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes. Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps […]

Mapping the humanitarian crisis in Syria

US State’s Humanitarian Information Unit collects, analyzes and disseminates unclassified information regarding humanitarian emergencies, and publishes high-quality maps that track relevant variables such as refugee migration and global health initiatives. The HIU team consists of roughly 20 analysts, researchers, geospatial analysts, cartographers and developers under the department’s Office of the Geographer and Global Issues. The […]

Maps to make sense of water pollution data

March 27, 2014 | Environmental Issues, General Science, GeoTechnology | by aHaSaN

In early 2012, the Environmental Protection Agency (EPA)’s Office of Water began an effort to simplify how it conveys the complex information it has collected for decades. Nine months later, the agency launched a map-based application called “How’s My Waterway?” that allows users to check pollution levels in almost any U.S. lake, river or other […]

New location based app development kit by ESRI

March 5, 2014 | Environmental Issues, GeoTechnology | by aHaSaN

With mapping firm Esri’s new software development kit, launched Wednesday, developers can create complex, polygonal “geofences” that trigger actions when people enter or leave them. A restaurant chain could, for example, use its app to send a push notification to customers that walk close to one of its locations. Or it could notify employees when […]

GIS is More Than Just Mapping

Why Use GIS? When floods in Colorado caused massive damage throughout the state in September 2013, geographic information systems (GIS) and web maps integrated current data, providing a comprehensive view of the constantly evolving situation to government officials and the public. An interactive public information map posted by Esri, a GIS software company, showed observed […]

মৃত্যু নিয়ে ভাবনা

February 28, 2014 | GeoTechnology | by aHaSaN

কোন তারা খসে গেছে আকাশ কি এসব মনে রাখে। খসে যাওয়া তারার মত খসে যাওয়া মানুষ-গুলোকে আমরা কি মনে রাখি? যদি রাখিই তবে কতদিন ? মানুষ মরে যায় কাঁদে শুধু তাঁরাই, যারা নির্ভরশীল। জীবিত নির্ভরশীলদের জন্য মৃত্যুটা হয়তোবা মৃত ব্যক্তির চেয়েও বড় বেশী ভয়ংকর। আমার চাচাত ভাই আবু বকর এর জন্য এখন সময়টা বড় বেশী […]

OpenStreetMap tags and taginfo

February 20, 2014 | GeoTechnology | by aHaSaN

OpenStreetMap data includes “tags”, name=value pairs which provide a free-form folksonomy approach to classifying features. To get started mapping you don’t need to know about these. With a easy to use “edit” interface, you can simply select from a range of feature types. For example if you select “post box”, then a node will be […]

Heart-shaped map projections

February 16, 2014 | GeoTechnology | by aHaSaN

A map projection is a way to represent the curved surface of the Earth on the flat surface of a map. A good globe can provide the most accurate representation of the Earth. However, a globe isn’t practical for many of the functions for which we require maps. Map projections allow us to represent some […]

“Chemtrails” – Fight to global warming !!! Will this geo-engeneering be boon or curse to human kind ?

Fact: Climate scientists lobbying for large-scale geoengineering According to a news of The Gurdian, the geo-engineers are finally coming out of the “chemtrail” closet, as reports are now emerging about deliberate plans in the works to dump untold tons of sulfate chemicals into the atmosphere for the purported purpose of fighting so-called “global warming.” The […]
