资源简介：
The Intertidal Extents Model (ITEM v1.0) product is a national scale gridded dataset characterising the spatial extents of the exposed intertidal zone, at intervals of the observed tidal range. The current version utilises all Landsat observations (5, 7, and 8) for Australian coastal regions (excluding off-shore Territories) between 1987 and 2015 (inclusive).
The Relative Extents Model (ITEM_REL_mosaic_1987_2015.tif) utilises the tidal information attributed to each tile observation to indicate the spatial extent of intertidal substratum exposed at each 10% percentile of the observed tidal range for the cell.
Attributes:
Single Band Integer Raster:
0 - Always water
1 - Exposed at lowest 0-10% of the observed tidal range
2 - Exposed at 10-20% of the observed tidal range
3 - Exposed at 20-30% of the observed tidal range
4 - Exposed at 30-40% of the observed tidal range
5 - Exposed at 40-50% of the observed tidal range
6 - Exposed at 50-60% of the observed tidal range
7 - Exposed at 60-70% of the observed tidal range
8 - Exposed at 70-80% of the observed tidal range
9 - Exposed at highest 80-100% of the observed tidal range (land)
