Project GIS Documentation

This document provides information and examples for Project GIS and will be in constant flux as new features are added. Any suggestions or feature requests can be made in the Project GIS forum.

Hint: Click on the layer name to see a sample of that layer.

Notes: Text layers return a maximum of 5,000 features. Image layers cannot take longer than 8 seconds to process. An error will be returned in each case. View documentation for each feature for any additional limitations.

In the example below you'll see the non-standard 'reflect' service used extensively. Using WMS or WFS is fine also. Read more about the reflect service and why it's used.

Data Sources

The following section will be of greatest interest to you and is where most of our efforts will be focused. Additions will be frequent and many. Features here require processing data into the database followed by writing often simple, often complex SQL queries that are fast and resource friendly. See what's new.
