The invention discloses a topographic map database updating automation method. The method comprises the following specific steps of: S1, comparing a terrain data change map and a topographic map database; S2, copying a topographic map frame into an updating range; S3, segmenting a boundary line of a map frame line and an updating line; S4, converting grating data and registering the grating data with a topographic database; S5, verifying the consistency by adoption of an automatic check program; and S6, copying the updated topographic map into the topographic database to be stored. The method is a real-time effective method for completing the existing information databases and realizing the topographic map database; the topographic map database is automatically compared with the existing topographic map databases by utilizing a high-resolution remote sensing survey technology to detect the terrain change, so that the labor intensity is reduced and the updating speed is high.
Description
Technical field [0001] The invention relates to the technical field of mapping and drawing, in particular to an automated method for updating a topographic map database. Background technique [0002] Updating the topographic map database is a long-term and arduous task in surveying and mapping information engineering. The current method of updating the topographic map database has the following problems: high labor intensity and long update cycle. In fact, keeping the data current is the most important issue in the application and development of topographic map databases. In a relatively short period of time, the change of topographic data is mainly the change of the feature data, and the change of the topographic data is generally small. The update of the topographic map database is mainly the update of the feature data. The usual method is to re-measure the features in a specific area and establish a new database to replace the old database. This method is slow. To this end,...
