![]() ![]() There are possibly four things going on: a) something in the projection information in the GeoTIFF tags is incorrect. If you can't use your original software to generate a smaller file that exhibits the same problems, well, then find a place from which people can download the 60 GB file you have. The second thing to do is to get a copy of the file that is being imported into the wrong place into the hands of the people who are attempting to find the problem. Talk about anything else just confuses things. Focus on getting the image imported with all coordinate system parameters set correctly. If Manifold is not importing the GeoTIFF into the correct place, the first thing to do is to stop any discussion about exporting to ECW or anything else. No need for an extra option to specify that. That's because Manifold automatically reads the projection info that's in the GeoTIFF. I can't seem to find an option to just use the projection as provided in the GEOTIFF. With the file in hand, then it's easy to import the file to see what happens, and to examine the file using various tools to see what it claims about itself. Regarding your import: that's not something I could help debug without having the original file that you're trying to import. Reading through this thread it could be you meant adamw's comment, but in his post I believe he meant to ask if you could use whatever software you used to create the problem GeoTIFF to create a smaller GeoTIFF that exhibited the same problem on import into Manifold. I didn't intend to comment on the import issue you had, just the sentence about not knowing that an image could be resized while maintaining the coordinate system. I can't see the logic in resizing an image that has not imported correctly in the first place? When I import to Manifold though, I can't seem to find an option to just use the projection as provided in the GEOTIFF, as can be found in Global Mapper etc? Can any of you shine some light on where I might be going wrong or as to how I can carry out a shift/rotate/scale within Manifold to get the image in the correct position? I know that I could use a WGS84 GEOTIFF which would most probably solve the projection issue, however when I export to ECW, this would not give a cartesian projection which is required by our other software? TIA. I've proved the GEOTIFF to be good by importing into other software such as QGIS and Global Mapper and checking against the many GCPs we have across the site. It is on a near scale 1 local cartesian grid (UK OS HS2 Snakegrid) but when I import into Manifold I am getting a shift/rotate and small scale error. I have a GEOTIFF of about 60GB, which measures roughly 3.5Km x 3.5Km at its extremes and has been exported from Propeller Aero. Hi all, I'm currently evaluating Manifold mainly for its ECW export function so that we can use the ECW with other construction surveying software but having some issues with the projection upon import. ![]()
