Shape

GpsTools v2.20 and later

A shape object contains a set of coordinates. Those coordinates are called "nodes".
A shape can be in any geographic coordinate system supported by Position.
A node is sometimes refereed to as a vertex or (many) vertices.
The nodes are divided into parts. If the shape contains a polygon, each part is typically a ring
in that ploygon. By default a shape contains one part.
A shape object can be used for many purposes:
> Be a container for GPS coordinates. For example when saving a track.
> Draw polygons, polylines and multipoints on a map. See MapShape.
> Read and write ESRI Shapefiles. See ShapeFile.
> Make GIS calculations. Shape.Distance calculates the distance of a track.
Shape.Area calculates the area of a polygon (ESRI shape).
Shape.IsInside checks if a node is inside a polygon.
Shape.IsIntersecting checks if two polylines or polygons intersect. And more...
check all methods and properties on the Shape class.
