Preparation of national base maps has been photogrammetrically conducted.The use of this technology will, however, face an obstacle in the cloudy area.Problem of cloud cover can be solved by using the technology of interferometric synthetic aperture radar (Insar) that uses two antennas to receive bounce back signal form certain oblects on the earth surface.Using the two data phases between the object-antena I and the object-antenna II will be obtained the phase difference in the same time .By using the untegrated data language (IDL) software, insar image can be processed into digital elevation modrl(DEM) mosaic as well as contour map. The prob lem of planimetrical position can be solved using differential global positioning system(DGPS) technology that is operated simultaniously while imaging.The planimetrical detail were extracted from the insar image using manual interpretation technique.The planimetrical map was digitized using auto CAD-13 software in order to join and stack contour map into base map of two scales, namely 1:25.000 and 1:50.000 To Know whether the obtained base map has met cartographical requirements, the comparison test was conducted using topographical map of 1:50.000 in scale and field test.Based on the result , it can be concluded that:there is still a little doubt in the result of the moun tainous area, while the result for the undulating and flat areas have met the cartographical requirements.
