Abstract

Topographical map is literally interpreted as written explanation on the field. This is a job where state planimetric position above the earth's surface and the shape of the ground surface is measured and drawn on paper with symbols on a certain scale. Several methods for topographic mapping are tachymetry, offset, photogrammetry, and a measurement of field table. There are two ways form of topographic mapping with photogrammetric, that are the aerial and terrestrial. To obtain more precise data it is not unusual that both of two methods are combined. The instruments used have also been growing very rapidly such as imaging and sensing technology known as remote sensing. In addition, photogrammetric method has more high accuracy, speed and ease of obtaining coverage detailed topographic.The map-making with photogrammetry are consists of basic map-making stage with photogrammetry, flight plans, aerial cameras, benchmarks and pre-mark installation, grand control surveys, aerial triangulation, aerial rectification photographs, field identification and delineation or cartographic. Several sources of error in photogrammetry, among others are scale errors, incorrect main location, negligence camera data, un-vertical shooting, and different flying height.Photogrammetric is so important, therefore careful planned in preparing the photogrammetry is required.
