Sorry if this seems dumb, but I have GeoTiff's that need editing and I really prefer to use GeoTiffs as a way for Resample to get it aligned in FSX especialy if you use multiple sources but when I save them in Photoshop it losses all the Geo data. Ughh! I can export the Geo Data using Glbal Mapper and I know there is a way but I cant find a way to add the Tag info back into the tiff after I ahve saved it.So I don't see how you can make a water mask geotiff as well as a blend mask as wouldn't all of those need to be GeoTiff as well?Thanks for any help.

Hi there,you don't need to "rebuild" the geotiff because resample.exe will be quite happy with a regular tiff. Instead, use the georeferencing and scale parameters from the tfw file and Photoshop to set up your inf file for resample. Specifically:ulxMap = -158.750278ulyMap = 58.600278nCols = 13672nRows = 6118xDim = 0.000278yDim = 0.000278(obviously, your values will differ).The other option is to re-load your Photoshop tif back into Global Mapper after making a copy of your original tfw file with the same name as the Photoshop file. Global Mapper will ask you about the projection parameters, which should be geographic lat/long and then will load your image, which you can then re-export as geotiff.Cheers, Holger

Holger,Thanks so much for the help!I used to do a lot of photo scenery design and "retired" after FS9 because of the limit on resolution, but with FSX I am excited again and having "fun"...So hats off to you and everyone on this forum.

If you store your geotiff and your world file from global mapper, you can re-insert the geotiff tags using a free utility call geotifcp.exe. The below link is not the download page, but it will get you there if you follow some links.You use the syntax, geotifcp -e myfile.tfw myinfile.tif myoutfile.tif"myoutfile.tif" is now a geotif using the info from myfile.tfw.Another freebe in the same family is listgeo, which displays the geotif tags...I use that sometimes to remind myself if I've even got a geotif or not.Best,Bob Bhttp://www.remotesensing.org/geotiff/geotifcp.html

Like I said, Hats off to you folks here!Thanks
