SRTM30 PLUS v8.0: Global Hillshading Rasters for GIS

SRTM30 PLUS v8.0 Digital Elevation Model data from Scripps Institute of Oceanography, UCSD was reprocessed to create global hillshading rasters. The dataset includes both a full-resolution and a lower-resolution, smoothed version optimized for zoomed-out map displays. This derived product was formatted as GeoTiff files by the NERP TE 13.1 eAtlas project to facilitate easy use in GIS applications.

Use Cases

• Create topographic basemaps for GIS projects based on the global hillshading raster.
• Visualize large-scale terrain features like mountain ranges based on the low-resolution smoothed hillshading.
• Integrate elevation-derived visual context into spatial analyses based on the processed DEM data.

Strengths

• Provides two specialized products: a full-resolution hillshade and a smoothed low-resolution version for different map scales.
• Based on the SRTM30 PLUS v8.0 DEM, a well-known global elevation dataset from Scripps Institute of Oceanography, UCSD.
• Formatted as GeoTiff files with internal overviews, which suggests optimization for GIS software.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2026-07-16 01:36:41.868982; freshness should be verified.
• Data may reflect geographic or source bias inherent to the original SRTM30 PLUS DEM.
