The science and art of producing maps had been subjected to the changes as a result
of new recent techniques developments at space photogrammetry, that lead to appearance
of programs and applications in the computer's world. This associated with th
e advent of
information age and Geographic information system that changed the traditional
topographic map from just a map to an analyzing and viewing tool.
All Syrian Topographic maps are old, out dated, and largely exist in paper form. Due
to the high cost of aerial photography, These maps have not been updated for many years
and such are not useful for planning. Therefore, there is an urgent need to produce new
maps using high resolution satellite images.
The research put a method for updating topographic maps of Al-Bahlolia district
which have scales (1/50000) and (1/200000), By using Cartosat1 images.
After updating, The results were that there is increasing in the area of planted land. In
addition to building developments, increasing of length and density of roads between and
inside villages. Contour lines also have been generated automatically, so efforts and time
were be saved.
