Geo-Info & Remote Sensing Institute (GRSI)

Objectives of GRSI

The goal of the Geo-Information and Remote Sensing Institute (GRSI) is to contribute to the achievement of sustainable environmental resource utilization in Zimbabwe and the region.
The objective of GRSI is to provide spatial data analysis solutions that would result in the management of the environment and natural resources in a more sustainable manner than would be possible without considering the spatial aspects.


  • Current Research Areas
    The spatial dimension is a required aspect of informed decision making. The GRSI has capacity to design and develop products that embrace the spatial dimension for informed decision making in:

    • Natural Resources Management;
    • Earth and Water Resources Management; as well as
    • Land Administration and Facility Management.
  • Areas of Collaboration
    The activities of the GRSI cover the Natural Resources Management; Earth and Water Resources Management; as well as Land Administration and Facility Management, and can be grouped as follows:

    • Collaborative research: Research with local or international institutions targeted at applications using spatial data analysis techniques to enhance resources management.
    • Customised service provision: Providing Remote Sensing (RS) and Geographical Information Systems (GIS) services to the public and private sectors in resources management by designing, developing and implementing methods that include the spatial dimension.
    • Product development: Developing spatial data analysis algorithms, models and software, that result in improved decision making about resource utilisation.
  • Products and Services
    The main activities of the GRSI focuses on research and development utilising the following capabilities:

    • Remote Sensing including: Preprocessing of Satellite Imagery, Geo-referencing and Orthorectification, Image Interpretation and Image Classification
    • Developing and maintaining spatially enabled databases, i.e. Geographical Information Systems (GIS) including: data capture (digitising and GPS surveys), Geo-referencing and Geo-coding, and map design
    • Spatial data analysis including: relational analysis such as overlays, buffering, and neighborhood analysis; spatial statistics such as Geo-statistics, point pattern analysis, spatial regression, and spatial modeling; as well as network analysis.
    • Operational Information Systems design with model application and WebGIS.
    • Open Source software integration.

    GRSI activities are done in collaboration with other Institutes at SIRDC and other Government Departments as part of the Stage Gate Approach, in order to benefit from teamwork and rapid project/product development.

  • GRSI Project Highlights

    • Monitoring of the effects of community soil and water management technology on agricultural production using satellite remote sensing for Practical Action Southern Africa.
    • Dust Fallout Modeling to assess the variations in levels of fallout dust from the source (Stack) to the receptor (community) for an International Cement Manufacturer.
    • Environmental Impact Assessment (EIA) for the proposed Chipara and Causeway dams with Remote Sensing and Geographic Information System techniques
    • Design of a GIS database consisting of natural resources, socio-economic, and infrastructure data for the Pungwe- Mutare Water Supply to be used in a detailed EIA
    • Formulate a methodology for monitoring vegetation changes, Vegetation Resources Information System (VegRIS) for the Forestry Commission, and to integrate this in land use planning. The system uses GIS, RS and Global Positioning System (GPS) techniques for the establishment of a woody cover map series of Zimbabwe
    • Coordinators for the European Space Agency environmental regional programs: GMES and TIGER, 2003 ֠2005
    • Spatial Data Conversion Project for UNICEF, Zimbabwe
    • GIS Needs Analysis for Department of Roads, Ministry of Transport, Infrastructure and Communications
    • Land Use/Cover mapping using high resolution SPOT satellite data for Guruve District, Zimbabwe: a CIRAD supported project
    • Assessment of national socio-economic and development statistics data for GIS as part of the SADC Development GIS project: a survey supported by SARDC
    • A digital environmental database for an international training session on leadership for environment and development: supported by Leadership in Environment and Development (LEAD) Project - Rockefeller Foundation
    • Ground water potential mapping and on-farm resources database for Debshan/De Beers
