Abstract

Precisely because of the expensive cost of GIS data capture and the fact that the procedures involved in this are also fairly time consuming, the sources for GIS data should always be carefully analyzed before selection in order to suit specific GIS application(s). There are many possible sources for GIS data available today. The criteria for assessing the most appropriate sources for GIS data include firstly, collecting only the necessary data and secondly, for cost effectiveness, accepting the minimum data quality that will get the specific GIS job to be successfully accomplished. Moreover, where geospatial data needs to be integrated, it is important that the various sources be critically examined for compatibility.
