I have seen the following posts, http://grass.itc.it/pipermail/grassuser/2006-May/034214.html and http://grass.itc.it/pipermail/grass-dev/2006-June/023820.html
I have access to orthorectifed high res imagery of towns and would like to start creating 3d models of buildings - would actually prefer to automate this process as much as possible. I do not have access to polygons of buildings with height. Once models are created they will be viewed on GoogleEarth. On the web I found out about a product callled SilverEye from Geotango - has since been bought by Microsoft :( - product info was saying SilverEye extracts 3d building models from single scene images. Any ideas on how I can then create 3d Models from imagery using OSS tools. -- Sindile Bidla
