I am having some difficulty aligning our maps. Our company currently surveys Targets in with high accuracy RTK gps and we then fly the mission and pickup the targets. Our issue lies with the EPSG codes. We do not survey in any particular coordinate system. Local ground coordinates only. Even if we were to use an EPSG code coordinate system some of our jobs are not close enough to published control points to get a baseline for the particular coordinate system. All we need to do is overlay our maps to scale over our surveys in CAD. When you scale the image with 2 control points as expected the map is distorted and the other control points do not fit. The only thing i have been able to do is use the rubbersheet command in Civil3d to manipulate the image based on control point coordinates versus selected points on the images. This works extremely well. 2d maps only of course. but all of our survey points match up with the map image within centimeters. i need to eliminate this Rubbersheeting process in Cad. so my question is…is there a way to calibrate the map in both directions so it is scaled properly to all of the control points. Using only 2d local coordinates? I need this to be done during the processing stage in drone deploy so when i output the image to our drafting department everything overlays perfectly. Some of our survey crews do not even use GPS so it is not possible to get into an “epsg” code system. we need the distances on the processed map between control points to match the measured horizontal distances on the ground…thats it!
