The gigantic task of preparation of digital Enumeration Area (EA) maps of whole Bangladesh was completed as a milestone initiative to move towards digital technology from conventional manual techniques. The nation-wide EA mapping based on aerial photographs and available conventional geo-information was initially constrained by a number of problems which were overcome and managed through innovative techniques. Mismatching of the administrative boundaries, digitized from the existing maps, with the aerial photo-mosaic appeared to be a critical problem. This mismatching caused relative geographical shifting of the locations of landmarks (surface features) on each EA map. Geographic feature based georeferencing backed by newly developed control point extension technique was employed to overcome this problem. The next problem was the requirement of time for composing thousands of EA maps. It was estimated that conventional technique based on composition of single map at a time required time that would override the project period significantly. A series map generation procedure was introduced to reduce the map composition time. Finally, monitoring of the progress of the mapping activities was an issue at management level that was addressed under the present work. A procedure to estimate time requirement for completing each task of EA map preparation was worked out. Based on the time requirement, a progress monitoring system was developed and introduced.
