OpenGrADS provides extensions and interfaces for GrADS.
The Grid Analysis and Display System (GrADS) is an interactive desktop tool for easy access, manipulation, and visualization of earth science data. The OpenGrADS Project seeks to develop advanced interfaces and extensions based on the main GrADS engine.
The project aims to make publishing of wildlife survey data easier using PHP Mapscript. By uploading survey or sightings data the user will be presented with a generalization map based on the Quarter Degree Grid Cell system.
