Mapping Cartography and Publishing Process in Digital Environment(2)

Fourth, digital map drawing and publishing advantages

Compared with traditional map mapping and publishing, digital map mapping has obvious advantages over publishing:

1. The digital cartographic drawing results are easy to store, and they are not easily deformed in the storage process, thereby improving the accuracy of map mapping.

2. Digital map mapping makes the map content easy to edit, modify, and update in the production process, and can supplement and modify the map according to the user's requirements, so as to enhance the adaptability, practicality, and user's breadth of the map.

3. The combination of digital map mapping and publishing reduces the heavy workload of operators and shortens the mapping cycle, saving materials and lowering costs. The tedious map design, map compilation, re-photocopying, copying, sub-coating, copying, tearing the film, adding sun drying and other transitional processes were combined on the computer. For a small number of copies of the map, inkjet printing or digital printing can be used for faster and lower cost.

4. Easy to modify, strong display. For frequently modified content, it is very convenient to use computer operations.

5. Increased the variety of maps and broadened the service area. The use of digital map mapping technology can produce a variety of digital map products, and can produce multimedia electronic maps, three-dimensional maps.

6. It is conducive to network transmission, remote replication, on-demand printing. In particular, when maps are needed in wartime, the latest map data and maps are quickly copied to print and copy maps in real time and quickly to meet the requirements of modern high-tech local wars on maps.

V. Conclusion

Digital map mapping and publishing is an important part of surveying and mapping safeguards. Its function and function, in the past, present and future, are irreplaceable and extinct. In the digital environment, with the continuous development of map mapping and publishing technology, we must be good at summing up experiences and discovering new problems, so that our digital map mapping and publishing will be fully digitalized to meet the needs of national defense construction and national economic construction. .
