Cartographic drafting is a major activity in the Geological Survey. As subdivision of Geo-Information; Cartography is responsible for the processing of regional and thematic maps and the drafting of illustrations by using GIS software applications. In addition Coreldraw and Autocad are used for the drafting of small scale maps and diagrams for publications in national and international journals.
Small Scale Maps done on CORELDRAW
Data capture is done by using the programs Arc/Info, Arcmap, Autocad and Coreldraw by way of digitizing from scanned data (images) and the use of digitizing tables.Digitizing (data capture) is a very time consuming exercise and made up the bulk the cartographic workload.

GIS supports several views for working with geographic information:

Geodatabase view:

Catalog ( GIS is a collection of geographic datasets-features rasters, topologies, etc.)

Geovisualization view:

The map; (GIS is an intelligent map view - queries, analysis and editing.)

Geoprocessing view:

Toolbox; (GIS is a set of geoprocessing tools – take information from existing datasets, apply analytical functions and write results.)
