R (>= 2.2.0), methods, sp, abind, pixmap
Provides bindings to Frank Warmerdam's Geospatial Data Abstraction Library (GDAL) (>= 1.3.0). The GDAL library is external to the package, and must be correctly installed first. Both GDAL raster and OGR vector map data can be imported into R, and GDAL raster data exported. Use is made of classes defined in the sp package.

Provides bindings to Frank Warmerdam's Geospatial Data Abstraction Library (GDAL) (>= 1.3.1) and access to projection/transformation operations from the PROJ.4 library. The GDAL and PROJ.4 libraries are external to the package, and, when installing the package from source, must be correctly installed first. Both GDAL raster and OGR vector map data can be imported into R, and GDAL raster data exported. Use is made of classes defined in the sp package.
for building from source: GDAL >= 1.3.1 library from http://www.gdal.org/download.html and PROJ.4 (proj >= 4.4.9) from http://www.remotesensing.org/proj/
