Areas

edigeo_type: edigeo_area

Features with their edigeo_type set to edigeo_area are either a single closed polyline feature (simple closed polygon), a donut, or an aggregate of donuts (and/or simple polygons). A simple closed polygon contains at least four coordinates, with the first and last coordinate being equal.

In an EDIGéO dataset, area features are constructed by gathering all edges that are related to the area feature. In this way, multiple area features may share adjacent edges, without duplication of the coordinates in an EDIGéO dataset. If access to these edges – not the constructed polygons – is desired, set the READ_RAW_DATA to YES.
