GeoFairy.Map wins in NGA Disparate Data Competition


GeoFairy.Map, derived from GeoFairy, is one of the final winners in Stage 1 of NGA Disparate Data Competition.

Geofairy.Map is a system created as an easy-to-go entry for the widely disparate datasets faced by both governments and corporations today. The system hubs many kinds of data sources, especially governmental datasets from NGA, NOAA, NASA, USGS, EPA, etc, and makes it much easier for people to discover, access, view and retrieve them via as few clicks as possible. With Geofairy.Map, users no longer need to jump about on the Internet and get exhausted to reach the information they are interested in. The time spent by users on data accessing is significantly reduced. This feature will be very helpful in the situations of emergency such as military actions, disaster responding and daily information quick inquiry. The datasets in Geofairy.Map are very heterogeneous in formats such as WMS, WMTS, ArcGIS REST, GeoJSON, Geopackage, ESRIShapefile, KML, NITF, GeoTiff, CSV, XLS, XML and GML. Geofairy.Map managed to manipulate them in a very uniformed, intuitive and secured interface. Geofairy.Map has both web based and mobile based clients. Everytime users submit any request, Geofairy.Map will repeatedly perform security checking on client, networking and server. The operation can be only processed when a clearance is granted for the current communication. Among the checking, client identity and networking anti-hijacking are the two major items that have to be validated. We designed and are making Geofairy.Map to take advantage of the Apple iOS Finger Print system to identify the users. On the backstage, as many data sources have restrictions on data access, we perform the server-to-server communication following secure channels and policies such as HTTPS, HTTP Auth, Token and WS-security policies.
