It is provided for convenience only, since these values can be computed from the map projection information above and the tiling information in the GVHDR file. Each row represents a single tile in the GVDR. Tiles are stored in this table in row-major, or scanline, order. The upper-left tile is stored first, then the tile to its right, and so on. The longitude and latitude values are given for the center of the pixel in each corner of the tile, so the tile actually extends one-half pixel beyond these limits. Carriage-Return Line-Feed 10 0 89 Tile Coord X 1 1 ASCII_Integer 5 The x-coordinate of the tile, with the leftmost tile at zero and coordinates increasing to the right. This is analogous to the SAMPLE value in PDS3 format IMAGEs. (Note that these 'tile coordinates' are unrelated to the pixel coordinates; they simply address the tile relative to the upper left tile [0,0].) The relationship between pixel coordinates and geographic location is given by the map projection defined in the cart:Cartography class. Tile Coord Y 2 7 ASCII_Integer 4 The y-coordinate of the tile, with the topmost tile at zero and coordinates increasing downward. This is analogous to the LINE value in PDS3 format IMAGEs. (Note that these 'tile coordinates' are unrelated to the pixel coordinates; they simply address the tile relative to the upper left tile [0,0].) The relationship between pixel coordinates and geographic location is given by the map projection defined in the cart:Cartography class. Top Left Longitude 3 12 ASCII_Real 11 degree The longitude at the center of the pixel in the upper left corner of the tile. Top Left Latitude 4 24 ASCII_Real 8 degree The latitude at the center of the pixel in the upper left corner of the tile. Top Right Longitude 5 33 ASCII_Real 10 degree The longitude at the center of the pixel in the upper right corner of the tile. Top Right Latitude 6 44 ASCII_Real 8 degree The latitude at the center of the pixel in the upper right corner of the tile. Bottom Left Longitude 7 53 ASCII_Real 8 degree The longitude at the center of the pixel in the lower left corner of the tile. -999.999 Bottom Left Latitude 8 62 ASCII_Real 8 degree The latitude at the center of the pixel in the lower left corner of the tile. -99.999 Bottom Right Longitude 9 71 ASCII_Real 8 degree The longitude at the center of the pixel in the lower right corner of the tile. -999.999 Bottom Right Latitude 10 80 ASCII_Real 8 degree The latitude at the center of the pixel in the lower right corner of the tile. -99.999 gvtgeom.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed gvtgeom.fmt 0 PDS3 Original PDS3 format file Carriage-Return Line-Feed
