About DISTAL
The DISTAL application will have the following basic workflow:
The user starts by selecting the country they wish to work with:
A simple map of the country is then displayed:
The user selects a desired radius in miles and clicks on a point within the country:
The system identifies all the cities and towns within the given radius of that point:
Finally, the resulting features are displayed at a higher resolution for the user to view or print:
We are going to implement the DISTAL system as a series of CGI scripts. While this is simplistic and lacks the look and feel of a proper Google Maps-like "slippy map" interface, it allows us to concentrate on the core geospatial aspects of this application without getting bogged down in the complexity of building a full web application.
