Uncertainty within GEOLocate
Polygons represented as a comma delimited array of vertices using latitude and longitude
Point radius and polygonal uncertainties
Supports auto-detection and generation of polygons (web app only, in development for desktop app)
Point radius represented as a distance in meters fromgeoreferenced point
