Abstract

This geodatabase contains all layers resulting from the georeferencing and digitization of the Hydrogeological Map of Lesotho and from the published technical notes accompanying the map.
The (digital) Hydrogeological Map of Lesotho (1994 – G. Arduino, P. Bono, P. Del Sette, Department of Water Affairs of the Kingdom of Lesotho) was imported into a GIS and georeferenced according to the geographical projection of the map. The hydrological data have been digitised and stored into a geodatabase.
The hydrological data were digitized into “feature classes” (points, lines and polygons), these are:
Rainfall (Rainfall stations storing mean annual precipitation, mean annual Evapotranspiration, mean annual Effective Precipitation); Geological Dikes; Geological Formations; Rivers; Hydrological Basins; Linear Springs; Contours of Mean Annual Precipitation; Contours of Mean Annual Effective Precipitation; Hydrostations for the measurement of Runoff; Location of rural settlements.

The map was georeferenced and vectorized by Luigi Simeone in 2017.
