That link isn't working. Why lyr or tiff files? Give me a simple *.lcp please.
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.
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.
Thanks, I'll try using GeoTiff in FlamMap.
