A Study Of The Prompt Making Technology For The Road Thematic Map At The Scale Of 1:10000

The prompt making system of the road thematic map at a scale of 1:10000 for the mobile operational zone is the sub-system of surveying and mapping support system. This system, which uses the road surveying data at the scale of 1:10000 in the campaign region and the vector topographic map data at the scale of 1:50000, produces the road thematic map at the scale of 1:10000. In this paper we will study the prompt surveying technology for the road thematic map at the scale of 1:10000 for the mobile operational zone. The main jobs are as follows:1. To solve the difficulties of precise registration between the RS images and the vector map. Putting forward the registration method triangle by triangle based on the TIN.2. Putting forward the method of single satellite image orientation based on the RFW, this method is the supplement of double image orientation method besed on the RFW.3. Coming true data pre-processing of the thematic map. It includes neighboring zone conversion, deleting the single features within the regulated region of the both road sides, data clip, data composition.4. Puting forward the method of data relationship processing for the road thematic map, that is to say,the method of rectification based on the measured road data, Providing the method of manual compilation., Implementing the display of the match map sheet.
