Polygon Layers

Scroll Prev Top Next More

PolygonLayers are one of the fundamental data types in Openwind. While they are somewhat similar to LineLayers, the difference is that they contain poly-polygons instead of poly-lines.

A PolygonLayer contains one or more poly-polygons where a single poly-polygon consists of one or more loops (at least three points). Polygons in Openwind are self-closing by virtue of their type.

PolygonLayers are useful for representing site boundaries, land parcels, water bodies, areas of roughness or vegetation such as forestry and so on.
