The MapInfo data dictionary V.1.2A was used as the standard metadata for updating the attribute table. This data dictionary provides details concerning name, data type and data description of buildings’ identification codes and building types, which are necessary for updating. Emphasis was placed on adding the missing information in the 2000 database, for instance the building types, building heights, building materials, and the number of storeys. Spatial data manipulation used for this project included spatial merging, dissolve and area calculation. Spatial merging was done by joining all updated buildings, roads and rivers from small maps (digitized from separate pieces of Ortho-aerial photographs) into one map that covered the entire CMCB. Calculation of geometry was done to measure the number of buildings and the aerial extent of buildings, as well as for measuring lengths of new roads and rivers
