What are the advantages of digital mapping compared with traditional mapping methods?

Original cartography uses paper, cloth or other visible real-size objects as carriers, and the map content produced is drawn or printed on these carriers.

Electronic maps made from digital mapping are stored on computer hard disks, floppy disks, optical disks or tapes. The map content is represented by numbers, and special computer software is required to display, read and retrieve these numbers.

Digital electronic maps can very conveniently combine and splice elements of ordinary maps into any form to form a new map.

By comparison, electronic maps under digital mapping have the following characteristics compared with paper maps: 1. Electronic maps use computer screens and large projection screens as media, while traditional maps generally use paper as the carrier of information.

2. The production, management, reading and use of electronic maps can be integrated, and any unsatisfactory areas can be modified conveniently and in real time.

The production, management and use of traditional paper maps are all separated.

3. The detail level of map content displayed on electronic maps can be adjusted at any time, while the content of traditional paper maps is fixed and unchanging.

4. Electronic maps can combine graphics, images, sounds and text, but paper maps cannot.

5. The use of electronic maps requires special equipment, but the use of paper maps does not.

6. Due to the limitation of computer screen size and screen resolution, the electronic map display effect is affected, and it is mainly displayed in blocks and layers.

Traditional paper maps are published and printed in full-page units. The format is large, the overall impression of map reading is profound, and the relationship between geographical elements is clear.
