| Abstract: | Using the case for 1:10 000 image topographic map in Guangdong Province, on the basis of investigation, analysis and production test, this paper designs one product pattern of image topographic map, discusses the key technologies such as contours generation, elevation point extraction, vector element selection, annotation,symbolization,and map border decoration.The corresponding production process and technical method are developed, and the product samples are made. These research results have formed a series of technical documents, which can provide reference for the design and scale production of image topographic map. |
