Hawaiian Islands High-Resolution Topographical and Ecological Raster Datasets for Conservation Planning 2025

This data release comprises a collection of high-resolution environmental raster data for the Hawaiian Islands, developed to support conservation planning and ecological research. The collection includes both 30-meter and 10-meter resolution GeoTIFFs with topographical variables (elevation, aspect, slope, hillshade, and geomorphon landform classification), as well as complementary ecological variables (vegetation height, habitat quality, and mean annual temperature and rainfall). All rasters have been processed to share consistent resolution, extent, and projection (WGS84), making them readily integrated into spatial analyses and tool development. The primary source data for the topographical variables was the USGS National Map. The dataset provides standardized environmental layers that can be used to identify suitable microhabitats for species conservation, restoration site selection, and ecological modeling across the Hawaiian archipelago.

This data release is divided into 3 files:
-a 10m resolution GeoTIFF raster stack containing multiple topographical variables for the Hawaiian Islands (elevation, aspect, slope, hillshade, and geomorphon landform classification).
-a 30m resolution GeoTIFF raster stack containing multiple topographical variables for the Hawaiian Islands (elevation, aspect, slope, hillshade, and geomorphon landform classification).
-a 30m resolution GeoTIFF raster stack containing multiple ecological/climatic variables that describe natural habitats across the Hawaiian Islands (vegetation height, habitat quality, mean annual temperature and rainfall).
