raster (version 3.0-7)

Geographic Data Analysis and Modeling

Description

Reading, writing, manipulating, analyzing and modeling of gridded spatial data. The package implements basic and high-level functions. Processing of very large files is supported. There is a also support for vector data operations such as intersections. See the manual and tutorials on to get started.
