Interactive Map Symbol Design And Editing Software To Achieve

Map is the simulation of the real world. It can express complex geographic components with abstract method. Map symbol is the graphics mark of these geographic components, and it's the language of maps. Users can interpret much geographic information on map with the help of map symbol. User can get even more information on map than maps with the processing of human being's brain.First, the article introduced the concept of the electronic map, and it also introduced the representation in psychometric and color of the electronic map. Second, the article explained the concept of the software engineering and some tools in common use. With practice, the author divided the software engineering into two parts: one was the technology, the other was the management. The author discussed how to put the software engineering in practice in the software programming. Third, the article described the expression method of the geomorphic data and the attribute data of map. With the modeling technology of Object-Oriented, the author realized the edit function of the electronic map, and he also realized the function of the map symbol's production. At last, this article gave the conclusion s and the expectations.
