I was thinking about a utility where you could select the date you wanted to check out the fires, then the utility would use gdal_rasterize on the appropriate .shp (or .kml) perimeters to generate blend masks. There could also be a supplied .tif and .inf for each fire so the utility could then call resample to compile all the burn perimeters on that particular date and move the .bgls to an active scenery area.
I guess I assumed everyone had OSGeo or FWTools installed, lol. Duh. That was dumb and of course won't work!
Better approach would probably be pre-compiled perimeters in folders by date and a utility that copies the appropriate photo.bgl to the scenery folder according to a selected date (or scenario if we did the missions). That would be much faster from the user's perspective anyway. I think I'll try a small sample with some imagery off the map server so it can be distributed, maybe 3-4 significant dates in the Kettle Complex fire as a test since it's relatively small. I'll try to post up a working sample tomorrow or the next day.
So I got (I'm told) an inch of rain yesterday! A cute little gopher just dug a hole in my yard though and the gopher mound is dry as a bone. It's very wet on top still, I even had puddles yesterday for a few minutes and I haven't seen that in 6 months. No fire worries today and there's supposed to be more rain on the way. I'm lighting the BBQ!
Oh, and the .kmls work fine with gdal_rasterize. Thanks for the info Orion and also thanks Lane and Paul for the input on "losing weight".
I think this should be Gary's new avatar, lol:
