The invention provides an intelligent road identification method and system in an electronic map. The intelligent road identification method in the electronic map comprises the following steps: a roadmarking step: obtaining the electronic map, and marking the road area in the electronic map as the specified colour; a block dividing step: dividing the marked electronic map into blocks according tothe specified precision, numbering the blocks, and establishing a corresponding grid array; and a block evaluating step: evaluating all the blocks through an established evaluation function, if the evaluation result is greater than the threshold value, setting the corresponding grid to 1, which represents that the grid can be walked through, and otherwise, setting the corresponding grid to the infinite, which represents that the grid cannot be walked through. A road is intelligently judged through map importing, small block division, block data analysis and use of the evaluation function. Bymeans of the intelligent road identification method and system in the electronic map in the invention, a user can import the map to identify the road; the user is greatly facilitated; and thus, the efficiency is increased.
Description
technical field [0001] The invention relates to the field of electronic map processing, in particular to an intelligent road identification method and system in electronic maps. Background technique [0002] Electronic map (English: Electronic map), that is, digital map, is a map that is stored and consulted digitally using computer technology. The method of storing information in electronic maps generally uses vector image storage. The scale of the map can be enlarged, reduced or rotated without affecting the display effect. In the early days, bitmap storage was used, and the scale of the map cannot be enlarged or reduced. Modern electronic maps Figure 1 Generally, geographic information systems are used to store and transmit map data, and there are other information systems. Electronic maps can easily combine and splice elements of ordinary maps in any form to form new maps. [0003] In order to realize navigation in the existing electronic map, it is necessary to establ...
