| Abstract: | DMC imagery is the main data source of a modern aerial surveys. Pingtan comprehen- sive experimental area as an example to test and put into production, the author study on process improvement of the large test area DOM procuct key technology based on MapMatrix platform： ①It can reduce adjacent model duplicate matching edit and improve the aeeurcy of DEM. ②It research fast batch production process potimization of the big area DOM. It u- ses＂ virtual concatenatino＂ concept, so the data bottlenecks were resolved. The large ca- pacity image datas are directly edited through mosaic line, and production efficiency are im- prove. |
