Multi-Directional Hillshade – shows hillshades computed from 6 different directions.Hillshade – a grayscale 3D representation of the terrain surface with a solar azimuth of 315 degrees and solar altitude of 45 degrees.Quick access to the following dynamically-generated elevation derivatives include: Datasets are described on the 3DEP Products and Services webpage. Availability and scales of data vary by location. All available resolutions of data can be visualized through the 3DEP Elevation Data Availability Index service. The most current, highest resolution elevation data available are highlighted as users zoom in to larger scales.
That data will continue to become increasingly available as 3DEP progresses towards its goal to complete nationwide lidar data coverage (IfSAR in Alaska) by 2023. The dynamic platform supports the exploration of Digital Elevation Models (DEMs) for the US and territories at a mixture of scales, including 1 meter DEMs. Elevation aspect map rendered in the 3DEP Demonstration Elevation Viewer.
