Shareloc, a simple remote sensing geometric library
===================================================

**Shareloc** is an open source remote sensing geolocation library.

Shareloc performs :ref:`user_manual_functions` between sensor and ground and vice versa: 

- Direct/inverse localization at constant elevation (ellipsoidal earth model).
- Direct localization on 2.5D DEM (w.r.t ellipsoid or geoid).
- Line of sight triangulation.
- Rectification grid creation.
- Rectification grid interpolation.

Shareloc handles RPC and direct location grids :ref:`user_manual_geometric_models`.

Why Shareloc ?
--------------

Shareloc development has been motivated by the need of a full python component for CNES studies and the need of an underlying geometrical component for CARS. 

Be aware that the project is new and is evolving to maturity with your help.
