With the digitization of maps, it becomes more convenient and faster to collect them, and widely being used. Actually the collection of maps are usually a small part of a large area, therefore, map conflation will be apparently important for map users. Nowadays, many maps’ produce methods are without features and landmarks, so we can’t conflation them correctly if we use the previously features and landmarks. Thus, the research is going to discuss using no features only side to conflate two maps, and propose that all dots have it 's own coordinate points.
By adjusting the orientation, in order to make two maps directly correspondence and produce new coordinate point set and cycling strings. Also use the Longest Common Substring to compare the string values of the two maps to get the longest same string fragments. Then use the original point serial numbers calculate the original coordinate X and Y values to conflate the two maps.
Key Words: map conflation, digital map, no feature, string searching
