Thanks, I'll try using GeoTiff in FlamMap.
Regarding the GeoTiff vs. LCP question-
GeoTiffs are used in IFTDSS downloads because they are the preferred method now as GiS etc. are advancing and all the models that used an LCP can also use a GeoTiff. For example LCPs cannot be opened in ArcMap but GeoTiffs can.
Here is a current version of that link:
Someone else on the team may be able to speak to why the tiff format is offered instead of .lcp.
That link isn't working. Why lyr or tiff files? Give me a simple *.lcp please.
