This study fused the four-band aerial image of Digital orthophoto Map(DOM) with the Digital Surface Model( DSM), digital elevation model(DEM),and basic surveying and mapping data of Digital Line Graphic(DLG) as the source of data, and realized the automatical information acquirement of water, roads, vegetation and constructions by eCognition software.The accuracy rate of the acquirement is over 80%,and basic acquirement is able to meet the basic requirement of land cover information collection within the geographical condition, furthermore, the second classification about the vegetation and constructions is of good reference function.This method has great advantages against the traditional one of artificial drawing,which improves the efficiency of surveying and mapping. Results demonstrated that this method had a wide application in theaerial image information acquirement of the geographical condition. Key words: aerial image; geographical condition; land cover; GIS database ³õ´Î·Ò룬»¹ÇëУ¶Ô£¬Íüϲ»¶·ÒëµÄÈËÖ¸Õý~~~ÃÀ²©·Òë2013-11-01 |
