The metropolitan area of Bangkok consists of 40 districts under the overall control of a Governor. In order to demonstrate the potential of spatial information handling technology in a developing country, a simple project in producing maps from existing BMA data was undertaken. Within the City of Bangkok various socio-economic and demographic data for each district are collated annually and included, as a normal practice, in a City Yearbook. Fig. 1 illustrates an example of the cartographic representation of the referred data sets.
