Hi Listers A client of mine has purchased some hard-copy aerial stereo-photos and wants to scan them for use as a base layer in MapInfo.
These photos are not rectified in any way for digital use, as they are designed for viewing in stereoscopic pairs. Obviously, the client is concerned about the distortion at the edges of the images - he is planning to use 5 photos for the area concerned. Once registered there is about 150m distortion at each photo edge. Placing vector layers onto the images is obviously going to be a problem as registration will be different for each photo image, so they will not currently display properly in MapInfo. Is there any software which will rectify the photos? (is this "ortho-rectifying"?). Or would specific rectified digital images need to be purchased for mosaicing in MapInfo? I have only used digital images, and have not tried using stereographic images for this purpose, so cannot advise. Any advice you may have for using these images in MapInfo would be most welcome. I will forward it to my client. Thanks Caroline ---------------------------------- Dr Caroline Hilton Pelican GeoGraphics Ltd UK [EMAIL PROTECTED] www.pelicangeographics.co.uk
