Hi All, I just downloaded a DEM file from geocomm.com, and its in a format that I do not understand, I want to do a Delaunay triangulation on it to generate a TIN. I was wondering if someone here knows how I can go about getting the raw x,y,z co-ordinates so I can go about triangulating this dataset? I know many of you might work with DEM and Raster datasets, so I thought I would ask here. Some details below about the dataset that came in the .TXT file with it. It was a ".DEM.SDTS.TAR.GZ" file which I untarred and it created a whole bunch of .DDF files. Any idea what I can do with these?
Thanks, Ed ITEM_TYPE: SDTS DEM - 7.5X7.5 GRID CELL_NAME: Bearhead Mountain STATE: WA MRC_CODE: 47121-A7 BEST_AVAILABLE: T SALEABLE: T DATA_LEVEL: 2 X_RESOLUTION: 30 Y_RESOLUTION: 30 XY_UNITS: Meter Z_RESOLUTION: 1.000 Z_UNITS: Meter ORIG_LOAD_DATE: 13-SEP-01 CREATE_DATE: 13-SEP-01 PUBLICATION_DATE: 17-SEP-01 SOURCE_DATE: 1979 INSP_REV_DATE: 1997 INSP_REV_NAME: Inspection HORIZONTAL_DATUM: North American Datum of 1927 PROJECTION: Transverse Mercator ZONE: 10 VERTICAL_DATUM: NGVD 1929 DIGITAL_FORMAT_SPEC: DEM SDTS (Part 5: Raster Profile and Extensions (RPE)) STANDARDS_NAME: Standards for Digital Elevation Models 1995 Header with Pre-1995 Content PROCESS_STEP: DLG/Hypsography LINETRACE, LT4X Complex Linear MIN_ELEVATION: 444 MAX_ELEVATION: 1859 SUSPECT_VOID: 0 PERCENT_VOID: 0 LARGE_CONTOUR_INT: SMALL_CONTOUR_INT: 40 CONTOUR_UNITS: Foot RMSE: 1 SAMPLE_SIZE: 30 NORTH_LATITUDE: 47.125000 SOUTH_LATITUDE: 47.000000 WEST_LONGITUDE: -121.875000 EAST_LONGITUDE: -121.750000
