  • 摘要:This paper concerned in computer aiddrawing in working station. Firstly, study precisionin large mapping using photogrammetry method;Secondly,collection data from field work and fromphotogrammetry , the data comunication betweendifferent type of computers and between computers andhandle computers. How to improve hardware andsoftware system in the proccesing data. And comparecadastral survey in Estern part and Arica.1 PRECISION OF SCALE MAPPING USING PHOTOGRAMMETRYMETHODThere is a test in one map, map scale 1:1000,photoscale about 1: 4000, about 50 checking points I theywere done using the theodolite T2 plus distance meterDI3000. Traverse accurate is 8". Meantime measuredchecking points in analog plotter B8S and analyticalplotter BC1.Its plalimitry precision as table 1 (forB8S) and table 2 (for BC1). Compare the differencesof coordinates between photogrammetry points andfield checking points. Get mean square error 0.481(for B8S) and 0.506 (for BC1).So we can say from test map, it can be got goodresul t using photogrammetry method in scale 1: 1000 inanalytical plotter and analog plotter.
