Would appreciate seeing pipelines described how to relate photogrammetry mapping deliverables to engineering plans for construction projects. Have had several jobs asking to provide project as-built info for comparison in AutoCAD to engineering designs. Am fairly sure I’m not doing it as well as it should be done.
Have found bits and pieces of answers via searches here and in the Mapper manual. Getting photogrammetry mapping results expressed in land-survey coordinates with accurate elevations was a challenge all by itself, but I can do that reliably now.
However, getting mapping deliverables into a CAD-useful file for comparing against design topography and features has been more challenging, especially since I don’t have AutoCAD to experiment with. It’s easy enough to overlay contours on an ortho-mosaic, and it makes a good visual, but it’s not useful for CAD unless I digitize contours manually.
Thanks for your patience/time……………… Bob R.
