GDMC

Geospatial Data and Modelling Centre

Data

As you may be aware, significant advances have been made in the fields of GIS and remote sensing in the recent years. More and more high resolution geospatial datasets (such as, rainfall, vegetation, topography, soil moisture, ground water, evapotranspiration, etc.) are now available free of charge! Unfortunately most of these datasets come in the formats which cannot be easily read or manipulated with common GIS softwares. As a results, their applications in Africa have been very limited.

WITEK Geospatial Data and Modelling Centre (GDMC) data scientists collect, download, harmonize formats, pre-process, archive and avail easy to use geospatial data to individuals and research groups working in key sectors: natural resources, climate change, agriculture, energy, health and built environment. Our research scientists are also dedicated to provide support in data analysis and model integrations.
