Overview
The polygon tracing services allows a user to step through a database of points
and draw geographic polygons for each using a map interface. The polygons for
each record are stored in the database along with the record.
A more descriptive overview and documentation are available here.
If you encounter any problems or find any cases where the software fails, we would like to hear
about it so we can work to improve the quality of the services. Please
let us know.
