GeoPolygon

GeoPolygon[{loc1, …, locn}] is a GeoGraphics primitive that represents a filled polygon whose boundary is formed by geodesic segments between locations loci and loci+1.

• GeoPolygon[{loc1, …, locn} -> {{q1, …, qm}, …}] represents a geo polygon with holes {q1, …, qm}, ….
• GeoPolygon[{poly1, poly2, …}] represents a collection of polygons polyi.
• GeoPolygon[{poly1, poly2, …}, sideness] specifies which of the two sides of each boundary polyi is in the interior of the geo polygon.
• GeoPolygon[polys, sideness, pathtype] represents a geo polygon whose boundary is formed by geo paths of type pathtype.

Examples

GeoGraphics[GeoPolygon[{GeoPosition[{40, -74}], GeoPosition[{45, -73}], GeoPosition[{42, -70}]}]]

GeoGraphics[{EdgeForm[Red], FaceForm[Opacity[0.3, Blue]], GeoPolygon[Entity["Country", "France"]]}]
