| Abstract: | In the applications of GIS, the electronic maps is renewed usually, especially electronic roads. The paper brings out an algorithm of fitting a straight line and hhers, analyzes the coordinate information of vehicle, then uses MapX groupware technology to realize the function of renewing electronic roads. In the actual application, this algorithm has advantages of high efficiency and low cost and then the difference with actual roads is nearly zero. |
| Keywords: | GIS electronic map renew MapX algorithm of fitting a straight line |
