I am a Botswana Registered Professional Land Surveyor and Academic in the field of Geomatics. My research interest heavily lies in Geographical Information Systems (GIS) and Spatial Data Infrastructures (SDI). I have played a pivotal role in the advancement of the Geomatics profession in Botswana by taking lead participation in Botswana Geomatics Institue (BIG) and representation of the same at the International Federation of Surveyors (FIG). My interest lies in using of geospatial information systems design and development to enable the environmental, political, social and economic activities and advancement of nations, in particular my own country Botswana.
Explorations of the differences between Gravity Recovery and Climate Experiment (GRACE) solutions... more Explorations of the differences between Gravity Recovery and Climate Experiment (GRACE) solutions in local regions and basins are fundamental in determining their suitability and applicability in these environments. Because of the different mathematical inversions used by the respective processing centers, individual solutions exhibit discrepancies in terms of mass increase or loss, which makes it difficult for users to select the best model for studying terrestrial water storage anomalies (TWSAs). This study compares TWSA trends, as derived from different GRACE solutions over the arid and semi-arid Botswana (2002-2019), where both storage and flux from CSR, JPL, GFZ, TUGRAZ, AIUB, and COST-G[1] were compared. The results show that the six solutions are fairly correlated with the least correlation of R=0.829 between JPL and AIUB, and a maximum of R=0.921 between CSR and TUGRAZ at a 95% confidence level. The TWSA analyses for 2002-2019 indicate that TWS is increasing in Botswana, wit...

In geo-information, data acquisition and management have manifested through technologies such as global positioning systems, remote sensing, geographical information systems, unmanned aerial vehicles and improved photogrammetric processes. With all these improved technological capabilities, geospatial data collection, processing and dissemination have become possible in greater proportions. To reap from this technological boom, the geospatial information community has come up with a pervasive and network enabling concept called spatial data infrastructure (SDI). Over the years, several countries have embraced the SDI concept to shape policy, build and share geospatial information resources. Some levels of successes have been reported in number of developed countries while developing countries have struggled. For instance, in 2010, SDI state of play asses...
