"Fitting" an aerial photo into a CAD drawing
"Fitting" an aerial photo into a CAD drawing
(OP)
Does anyone know if there is an EASY way to "fit" an aerial photo into a AutoCAD drawing?
I am using AutoCAD 2002 and have a pretty accurate drawing of a large site (~1 mile by 3/4 of a mile) that shows some buildings and roads in the area. I referenced in the image of an aerial photo because I want to underlay the map and be able to draw in some more features by tracing the photo.
I realize the photo has error in it and I know that is why I cannot just plop it into the drawing and have everyhting match up, so I am trying to figure out if there is a tool or method of stretching or rubbersheeting the photo??? I think there is a tool in ArcView that will do something like that but since I am using AutoCAD that doesn't really help...
Any ideas or knowlege would be much appreciated, thanks.

If that doesn't work, there's IRFAN Viewer, which is free to try and has a resampling function that allows you to change the number of pixels in a picture.

MEM1...it is a photo we had flown...so if I understand you I think you are saying I can scale the image to whatever scale they flew it at? I will try it...
JKinzenbaw...I don't have CAD Overlay but I have heard other people talk about it, is it like Raster Design because I could not find anything about Overlay on Autodesk's website. That "align" command will be handy...
Thanks all...

CAD Overlay is Raster Design, they changed the name in between v.2002 and v.2004 I think. Also I believe you can use the "align" command with any version of ACAD it's "rubbersheeting" images that you need Raster Design for. Just another tid-bit-- Raster Design is also handy with geo-referencing images to the coordinate system of your choice and exporting .tfw's to give your images known location.

I have overlain a 8km radius photo over the GPS data with reasonable accuracy. If the need for the match is to be fairly good then a ground survey is the best approach.
