Hi,What Datum does FS use for North America?How would you convert NAD83 BIL files to the Datum FS uses before running Resample.exe? Is there a program that does this?Thanks,Tim

Hi Tim,The NAD83 and WGS84 datums are virtually identical, so I wouldn't worry about the datum conversion. The differences are inconsequential for our purposes.Just make sure your source data is unprojected latitude/longitude format.-------Justinhttp://www.fsgenesis.netHigh Quality Scenery for FS200x

Thanks Justin,I understand your reply to mean FS uses WGS84. If so that's great news, as my handheld GPS can use that also.It also explains why my pictures/screen shots in the URL of my prior post (thanks and comparsion), shows the airport L00 differently. (N 34
