In order to illustrate the requirement of resources to develop computer assisted mapping for census and survey operations, below is a hypothetical example with rough input estimations. We may conjure up a country with population of about 10 million people which has about ten 1st order administrative divisions and about 20,000 EAs. Let s further assume that the hierarchical administrative structure of the country is: division (10), department (200), district (1,000). To process, one can first implement applications at the division level. On average, each division has 20 departments, each department has 5 districts and each district has 20 EAs. The number and complexity of maps needed will therefore be:
- 1 country map showing boundaries of 10 divisions and 200 departments;
- 10 division maps, each map showing boundaries of 20 departments and 100 districts;
- 1,000 large scale district maps, each map having all necessary details for the delineation of 20 EAs.
Staff requirement: to carry out this operation, it is estimated that a staff of about 22 persons will be needed, divided in 5 groups of 4 each with 2 supervisors (staff are from the data processing and Equipment requirement: 20 PCs, 5 scanners, and 5 digitizing tablets.
Time: 10 months.
On average, each group of 4 staff with 4 PCs will process a geographical database of about 20 large scale district maps per month.
