description: The TOPODATA dataset provides a Brazilian collection of geomorphometric variables derived from SRTM (Shuttle Radar Topography Mission) data. Original 3-arc second (~90 m) resolution elevation data were refined to 1 arc second (~30 m) through kriging interpolation, followed by geomorphometric derivations such as slope, aspect, profile curvature, and plan curvature. Secondary products include landform classification, dividors and drainage delineation, and shaded relief (hillshade) maps. The dataset is distributed as Cloud Optimized GeoTIFF (COG) and aims to support geosciences, environmental management, territorial planning, agriculture, hydrology, and geomorphological research across Brazil.
