亚米制卫星图像（Pleiades, GeoEye）为地图更新提供了优势，例如有趣的地面分辨率，良好的反应性和捕获大区域的能力。本文介绍了利用此类立体影像进行GIS地形数据库建筑对象间二维变化检测的实验。已经测试了两种方法。第一种方法是从卫星正射影图和附加信息（相关DSM-DTM，数据库）中提取土地覆盖，并将该分类的建筑对象与数据库中的建筑对象进行比较。第二种方法是将数据库建筑对象的高度信息与DTM相结合创建伪DSM，并将其与从卫星图像计算的相关DSM进行比较。获得的结果是相当令人鼓舞的，即使正确率对于操作使用来说仍然太低。
Submetric satellite imagery (Pleiades, GeoEye) offers advantages for map update purposes, e.g. an interesting ground resolution, a good reactivity and the ability to capture wide areas. Experiments on the use of such stereoscopic images for 2D change detection among building objects of GIS topographic database are presented in this paper. Two approaches have been tested. The first one extracts land cover from satellite ortho-images and additional information (correlation DSM-DTM, database) and compares building objects of this classification to those of the database. The second one creates a pseudo-DSM from height information of database building objects combined with a DTM and compares it to a correlation DSM computed from satellite images. Obtained results are quite encouraging even if the correctness rate remains too low for an operational use.
