Current version provides low-level bindings. Future versions might provide a higher-level wrapper around native functions and data structures.
In addition to Proj4 library bindings this package a number of utility functions, including:
- Parsing degrees from a string and conversion between degree-minutes-seconds and decimal representations
- Simplification of polygons/polylines (reducing number of vertices) using the Ramer–Douglas–Peucker algorithm
- Projecting points from a geographic space onto a screen with the given dimensions and viewport
- Construction of circular lines with the given radius and center (like missile ranges, etc.)
it also provides bindings to the set of geodesic calculations API from the recent Proj4 distributions.
