Spatial analysis

If you require complex analysis but the installation of a complete geographic and geostatistical analysis system is excessive, we can take care of all your analysis needs, from sourcing base data, to developing multivariate geostatistical models, through to preparing final outputs in either a traditional or web format. 

The main tools at our disposal include:

  • GRASS for topography, network, image, vector and raster analysis
  • R for geostatistics
  • PostGIS (features more than 600 tools for vector and raster geoprocessing)

GIS analysis - GRASS

http://grass.osgeo.org/

GRASSGRASS (Geographic Resources Analysis Support System) is a Free and Open Source software for carrying out spatial analyses. It includes more than 400 modules for working with vector (2D/3D), raster and voxel data. GRASS is able to interface with a number of other programs and GIS packages to provide geostatistics and web based GIS analysis applications.

Under continuous development since 1982, GRASS can be used as a complete GIS desktop application, or as a key component of a wider GIS infrastructure. GRASS is distributed under the GNU General Public Licence and supports a wide variety of vector and raster data, images and databases.

Today GRASS is used in scientific, commercial and government sectors and has demonstrated high efficiency in solving a wide range of spatial problems around the globe.
