Microstation v8i-based city rapid-modeling method

The invention discloses a Microstation v8i-based city rapid-modeling method, which comprises the following steps of: performing an aerial survey on a tested area according to a conventional aerial photogrammetric survey method by adopting an aerial photogrammetric survey system; and 2, performing analysis processing on aerial survey data in a Microstation v8i software environment by using a processor, namely, establishing a three-dimensional aerial photogrammetric survey model, performing land feature classification and marking, correspondingly establishing a land feature type layer-color mapping table, performing vector data acquisition, establishing models of houses, scattered trees and land features of other types respectively, processing all the land features in the tested area respectively, and obtaining three-dimensional geometric models of all the land features in the tested area.
