Description
The products represent the first openly accessible high-resolution DTM for this region, thus supporting applications in landslide susceptibility mapping, environmental modeling, and territorial planning. This open-access initiative contributes to bridging the gap in Brazil’s high-resolution topographic data availability and fosters both scientific research and evidence-based decision-making.
