资源简介：
The NEON AOP LiDAR Slope and Aspect product includes a slope map and aspect map, both in raster GeoTIFF format. Slope and aspect maps are derived from the DTM, which includes only elevations which relate to the physical terrain or “bare earth” surface model. Raster maps for the slope and aspect are reported with horizontal reference to the ITRF00 datum and projected to the Universal Transverse Mercator (UTM) mapping frame. Slope is determined as the angle between a plane tangential to the local terrain surface and a plane tangential to the local Geoid12A surface, reported in degrees. Aspect is the direction of the steepest slope, given in degrees referenced to grid north. The slope and aspect rasters are divided into a set of 1 km by 1 km tiles, which have corners spatially referenced to an even kilometer. The filenames contain the coordinate of the lower left corner (south-west) of the tile.
Latency:
AOP data will be available 60 days after the final collection day at a site.
