The map provider I get images from does not have a WMS service. I have tried to get tilecache to run on IIS and was never successful. Hence I am grabbing the lat/lon coordinates returned by openlayers creating a single tile and then presenting the image to the user.
My customer says the following: *Looking at the header info on some images downloaded today it appears you are navigating along a lat lon grid as if it were orthogonal. Unfortunately this doesn't work with the imagery as served by the map providers. they "orthorectify" the images so the tiles are in a Cartesian space rather than a spherical space. The means when you move straight east or straight north neither lat nor lon stay constant.* How would I go about orthorectifying my scenario. Would tilecache take care of this? Would some minor adjustments to the panning work? Thanks, Linda Rawson
