Loading ASTER GeoTIFF DEM

Hi, New user here.

I've been trying to load the ASTER GEOTIFF DEM data as an elevation map, but I can't figure out how to do it. So far I have only been able to load it as a normal Raster->GEOTIFF->"30meter (BW)" map.

I've tried to make a LIDAR directory under a VMAP directory and get FalconView to recheck the data using the map manager, but I still don't get the LIDAR map. However, skyview gives me the option to load its elevation data from the GEOTIFF 30 Meter BW.

I am using FalconView 4.2.1.1005

    Could you, by any chance, be more explicit about how you solved the problem, that is, how did you convert your data using 3DEM? I am running into a similar issue with a dataset and it sounds like you may have found a common solution. I have opened my dataset in 3DEM, but don't see an option to change bit-depth or image format.

    Thanks, in advance, for posting

    Finally solved my problem.

    After monitoring file and network read/writes, I figured that FalconView was parsing all the files but wasn't recognizing them as GEOTIFF DEM's.

    I did some more research on the ASTER files and found out that while they are GEOTIFF DEM's, they were of a different specification. Didn't delve much into it but it seems that the ASTER's were 16-bit, while normal ones are 24-bit. Got around the problem by using 3DEM to convert the data.

    Thanks for the help.

    Now, if only I could get FV to generate smooth contour lines using GEOTIFF's.:D

    just to clarify, is there a naming convention or folder structure I have to follow (like in DTED files)? The full path to the DEM right now is "C:\Documents and Settings\All Users\Documents\PFPS\LIDAR\ASTGTM_N14E121_dem.tif", but FalconView does not seem to recognize it. The data check log says "files: 0" for LIDAR

    Tried putting the data in a LIDAR directory under the default map path (I'm in xp, so "C:\Documents and Settings\All Users\Application Data\PFPS\LIDAR\", still no joy. The data does not come up as an elevation nor as a goetiff map.

    It should go in the LIDAR directory under your map path (not under the VMAP directory).

    So by default (in Window 7) you have a map path of: C:\Users\Public\Documents\XPlan

    You should put the DEM in: C:\Users\Public\Documents\XPlan\LIDAR\

    And do a data check on the path.

    I would just like to add that skyview loads the GEOTIFF DEM, but it shows everything as white unless I get very close to the terrain, then it colors it green, yellow and red according to elevation.

    I also had problems loading the WMS_Map_Installer utility, but after looking at the error log, it seemed that the fresh install is looking for "C:\Documents and Settings\All Users\Application Data\PFPS\data\WMS_MAPS\default.XML", where only a OpenStreetMap?.xml or WMS_MAPS_Default.xml (forgot what exactly) existed. Solved it by renaming the existing xml to default.xml.
