Ok...Now that I can actualy make bgl files out of a ned file...I am trying to use multisource files....The only peoblwm is this....it starts and does a rapid 0.....10....210.... you know that stuff...Well it does that quickly, for like 2 min and then stops, but nothing... I looked and relooked and I am just baffeld...I was using SMRT data and the smrt 2 bgl. but decided to try this ned stuff... I really like it... IF I can figure out the inf stuffhere is both my single Inf and then my multi inf----------------------1.inf(Destination) LOD= 10 DestDir= C:Documents and SettingsDavidDesktopTerrain_Tools DestBaseFileName= 1 UseSourceDimensions= 1(Source) type= Elevs16LSB SourceDir=C:Documents and SettingsDavidDesktopTerrain_Tools SourceFile=1.BIL Lat= 35.50004629529023 Lon= 112.75004629532987 NumOfCellsPerLine=8101 NumOfLines=5401 CellXdimensiondeg=0.00009259259260 CellYdimensionDeg=0.00009259259260 scaleinmeters=1.0--------------------2.inf(Destination) LOD= 10 DestDir= C:Documents and SettingsDavidDesktopTerrain_Tools DestBaseFileName= 2 UseSourceDimensions= 1(Source) type= Elevs16LSB SourceDir=C:Documents and SettingsDavidDesktopTerrain_Tools SourceFile=2.BIL Lat=36.00004629533028 Lon=112.75004629532987 NumOfCellsPerLine=8101 NumOfLines=5401 CellXdimensiondeg=0.00009259259260 CellYdimensionDeg=0.00009259259260 scaleinmeters=1.0----------------------3.inf(Source) type= multiSource numberofSources=2(Source1) type= Elevs16LSB SourceDir=C:Documents and SettingsDavidDesktopTerrain_Tools SourceFile=1.BIL Lat=35.50004629529023 Lon=112.75004629532987 NumOfCellsPerLine=8101 NumOfLines=5401 CellXdimensiondeg=0.00009259259260 CellYdimensionDeg=0.00009259259260 scaleinmeters=1.0 (Source2) type= Elevs16LSB SourceDir=C:Documents and SettingsDavidDesktopTerrain_Tools SourceFile=2.BIL Lat=36.00004629533028 Lon=112.75004629532987 NumOfCellsPerLine=8101 NumOfLines=5401 CellXdimensiondeg=0.00009259259260 CellYdimensionDeg=0.00009259259260 scaleinmeters=1.0(Destination) LOD=10 DestDir=C:Documents and SettingsDavidDesktopTerrain_Tools DestBaseFileName=3 UseSourceDimensions= 1------------------------------------Ok to me this all looks good, but something is wrong.The 1 and 2 inf work fine and perfect, but the 3.inf just wants to put up the 0's and 10's for fun...So a prompt reply would be helpful...Thanks,

Hi David,When using multisource you must specify the boundary dimensions. (Destination)LOD=10DestDir="C:Documents and SettingsDavidDesktopTerrain_Tools"DestBaseFileName="3"NorthLat = 35.947265625SouthLat = 35.068359375EastLong = 112.03125WestLong =112.734375(Source)type= multiSourcenumberofSources=2(Source1)type= Elevs16LSBSourceDir=C:Documents and SettingsDavidDesktopTerrain_ToolsSourceFile=1.BILLat=35.50004629529023Lon=112.75004629532987NumOfCellsPerLine=8101NumOfLines=5401CellXdimensiondeg=0.00009259259260CellYdimensionDeg=0.00009259259260scaleinmeters=1.0(Source2)type= Elevs16LSBSourceDir=C:Documents and SettingsDavidDesktopTerrain_ToolsSourceFile=2.BILLat=36.00004629533028Lon=112.75004629532987NumOfCellsPerLine=8101NumOfLines=5401CellXdimensiondeg=0.00009259259260CellYdimensionDeg=0.00009259259260scaleinmeters=1.0The boundary coordinates must fall on the edges of each LOD 10 quadrant or you will have missing data.
