GIS and Remote Sensing

GIS and Remote Sensing

A research group, providing timely geospatial products and services for industry and government, specializing in the use of geospatial techniques and technologies [satellite and airborne multispectral and hyperspectral imagery, DEMs, client-provided data, GPS data and GIS] in environmental baseline and resources mapping/analyses/modeling.

The group is composed of dedicated and skilled professionals in Remote Sensing, GPS and GIS/related geo-spatial technologies, specializing in the analysis of satellite and airborne imagery, which is used in combination with a variety of complementary data sources and techniques, to characterize any landscape (urban and non-urban) as a spatial solution tool for complex planning & monitoring processes.

The group uses spatial analysis tools, Geographic Information Systems (GIS), Global Positioning System (GPS), Remote Sensing (RS) for data analysis and storage. Utilizes a range of best practice, industry standard, image processing and GIS (Geographical Information Systems) software, including ERDAS and ArcGIS. Combined with other complementary tools. This comprehensive range of geo-spatial mapping, modelling and classification capabilities ensure quality analysis and product output. A growing feature of the group entails partnering with other organizations to leverage complex skills compliments to collaborate on a multidisciplinary level. The group has been the partner of choice, in many projects requiring geographic image and data analysis, with both public and private sector organizations, both nationally and internationally.

  • Our activities cover an impressive range of thematic areas. Our most common application of these thematic areas is for environmental and agricultural applications.

    • Environment
      Land cover/land use mapping and change analyses, soil erosion modeling, air & water pollution
    • Agriculture
      Crop monitoring, crop acreages estimation, agrometeorological modeling, crop yield forecasting, precision farming
    • Urban studies
      Urban mapping, baseline maps, multi-criteria based optimalisation, resource-demand tasks
    • Defence, security, hazards
      Map update, terrain analysis, flood monitoring, multi-criteria risk analysis
    • Earth exploration
      Oil and gas exploration, water resource detection, geological mapping
    • Forestry
