VTE File Creation By: Ricardo Veguilla Vazjier Rosario WALSAIP July 2008

VTE Supported Files & Procedure Texture BMP JPEG PNG GIF Elevation USGS DEM Binary Terrains (bt) Grayscale images Must Know If the file is partitioned Partition sizes Blocks/HDR filenames Notice that to create the VTE file: The Elevation and Texture files must be on the same directory as the VTE file. VTE must be the first word in the file. The Elevation and Texture filenames must include the file extension. A texture image is compose of color (RGB) pixels “samples” A DEM sample means an elevation sample (equivalent to a grayscale pixel) Each full resolution texture or Dem will be sub-divided into (x_blocks * y_blocks) each of block_size samples.

Size of the blocks in samples 2.Number of blocks in x 3.Number of blocks in y 4.Dem file width in samples 5.Dem file height in samples 6.Texture file width in samples 7.Texture file height in samples 8.Full resolution Dem file name 9.Full resolution texture filename 10.Array of Dem blocks filenames 11.Array of Texture blocks filenames VTE FileFiles Associated

VTE FileFiles Associated Following the same format as before, the pointed header files will actually point to the jobos_dem & jobos_texture header files, which are the ENVI headers for jobos_1k_dem file and jobos_1k_texture file.
