|---|---|---|
| spatial reference system | NAD83 / Texas Centric Albers Equal Area + NAVD88 height (m) | projection + datum (unit of measurement) |
| geographic extent | (-106.406273, 25.596806, -92.787879, 36.533266) / (855152.043513, 6850656.706461, 2146849.196814, 8066373.253837) | boundary box of the tile |
| tile width | 256 pixels (256 meters / ~840 feet) | width of the tile |
| tile height | 256 pixels (256 meters / ~840 feet) | height of the tile |
| tile overlap | 0 pixels (0 meters / 0 feet) | overlap between adjacent tiles |
| pixel width | 1 meter (~3.3 foot) | width of each pixel |
| pixel height | 1 meter (~3.3 foot) | height of each pixel |
| nodata value | -9999 | pixel value indicating absence of data |
| file format | Cloud Optimized GeoTIFF | file type |
