摘要：In this paper we report on the results of two projects conducted recently for the AMilGeo (Amt für Milit.risches Geo- wesen) of the German Federal Armed Forces. The aim of the first project was to establish an operational workflo w to update existing VMap Level 1 data using commercially available satellite imagery. The complete workflow, primarily based on Intergraph software, was tested successfully with several examples and integrated into the existing VMap1 production environment. Additional software was developed for the feature linking of the "old" VMap1 data and the "new" topographic features extracted from the satellite images. The second proj ect was a study focused on the genera- tion and update of VMap Level 2 data using both satellite and airborne imagery. It was investigated in detail, which VMap2 features can be extracted from different satellite and airborne imagery b y a human operator.
