features library Null safety
Doing geospatial calculations requires feature types. This library provides a set of feature types for use in geospatial calculations.
The Feature class is the base class for all feature types.
Classes
- Coordinate
- The base coordinate class, used by all feature types.
- Feature
- The base class for all feature types.
- FeatureCollection
- A FeatureCollection is a collection of Features.
- LinearRing
- A LinearRing is a closed series of Coordinates. It is used in Polygons and MultiPolygons. Closed means the first and last Coordinates are the same.
- LineString
- A LineString is a Feature made up of connected Coordinates to form a line.
- MultiLineString
- A MultiLineString is a Feature made up of a List of LineString Coordinates.
- MultiPoint
- a MultiPoint is a collection of Coordinates that share properties.
- MultiPolygon
- A MultiPolygon is a collection of Polygon Geometries with shared properties.
- Point
- A Point is a single position in a coordinate system, with properties.
- Polygon
- A Polygon is a single closed path with shared properties. The first LinearRing defines the outer boundary of the Polygon, while the following LinearRings define holes within the Polygon.
