The point-to-space display mode shows the average of a measure for a portion of space (as defined polygons) from the viewpoint of the cursor's position.
The integration of all these georeferenced layers generates uniquely defined polygons in a Geographic Information System (GIS) that cover the entire national territory.
A segmentation algorithm [34] that groups neighboring pixels into polygons, with 1 ha minimum mapping unit, was applied to the output to remove scattered pixels and define polygons that more realistically correspond to landscape features.

Users can additionally use spatial parameters, such as the current map window, a user defined polygon and HUC-8 watershed or county boundaries to refine their selections.
Users can discover data by querying for specific parameters, or using spatial boundaries such as HUC, county, a buffered point, or a user defined polygon.
The hold-out set was selected using a spatially and temporally declustered algorithm [ 39] which defined Thiessen polygons around each survey location.
This algorithm defined Thiessen polygons whose boundaries enclosed the area that was closest to each point relative to all other points around each survey location.
The tantalum markers mounted on the implant define a polygon.
More specifically, the proposed algorithm defines a polygon for each star, using the neighboring celestial bodies in the field of view as vertices.
A cage defines a polygon by joining its vertices in order, the last with the first and removing the middle point of any consecutive collinear triplet (to fulfill the polygon definition).
