GeoDiff is a tool for computing the delta of two snapshots of a spatial data set.
It also comes with a web interface to compute and visualize the differences directly in your browser!
We like to call it
the Unix diff tool for geographic data - Didier DONSEZ
GeoDiff is part of the 4th year innovative project at Polytech' Grenoble, France.
It is developed by three RICM (Networks and Multimedia Communication) students:
The project's supervisor is Nicolas Palix.
You can find more information on
- the main page of the project [FR]
- our project progress report page [EN]
Available soon on the wiki.
The web interface is available on my [Hbecher] personal site here.
The GeoDiff command-line tool is written in Java, and uses
- Gson (from Google) for manipulating JSON objects (under Apache License 2.0)
- GeoGSON, GeoJSON addon for Gson by user filosganga (under Apache License 2.0)
- JOpt Simple for parsing command line options (under The MIT License)
The web interface uses jQuery and Leaflet (jQuery will be removed in the near future, it was used only for deep copying an object).
It embeds a delta computing module, written entirely in JavaScript, that can process GeoJSON files.
