The Grid Library (libGrid) is the resampling backend for the libMini terrain rendering engine.

The library aims to provide a generic resampling tool for a wide variety of geospatial terrain data and imagery building on GDAL. Its main application is to produce terrain tilesets that can be displayed with the libMini terrain rendering engine.

The library also provides convenient methods to manipulate geospatial raster data. This includes the reprojection, transformation, interpolation and modification of the image data or height fields. The library utilizes image pyramids to avoid aliasing artifacts.
