ANNEX: Base Map Preparation using GIS

Using GIS software is faster, flexible and more precise way of base map preparation. It is faster than direct enlargement of topographic map since contours can be generated automatically and the resizing of the base map to its actual size on the 3D map can be done in few clicks. Map elements and other map features and attributes can be added before the printing and thus more flexible. It is also more precise in a sense that contours are generated automatically and the actual dimensions or size can be verified before printing. However, all these practicalities of base map preparation using GIS are only possible if there are GIS software, GIS data and GIS personnel. If these are non-existing, then base map preparation using GIS is not practical at all.
