This paper describes how geographic information system (GIS), remote sensing (RS) and Global Positioning System (GPS) technologies were used to plan the collection of entomological baseline data for a tsetse and trypanosomiasis (T&T) elimination project in the Mouhoun river basin in Burkina Faso. Historical data were collated as the background for data analysis. These data were used to define t...
