GIS and RS expert is here to do the job. I think, these are UAV collected images, with are geo-referenced and using ArcGIS or AutoCAD map 3D these can be easily vectorized. As per the dwg file, we need manual vectorization to extract all information, for which on screen digitization would be best and accurate possible way to do. Let us discuss to find more, i did lots of GIS and digitizing work, even using Quickbird images and Google earth pro. These are easy job for me, can give you the vectorized format in dwg or shp file as you need. Hope to have a discussion, thanks in advance. Regards; Labib
