Altitude Ranges
Polygon Layers Representing Altitude Ranges Across the Amazon Region
This dataset illustrates the distribution of various altitude intervals in the Amazon. It highlights the extent of coastal and lowland areas as well as mountainous regions. Altitudinal ranges and the general terrain configuration are essential for understanding landscape variability and biodiversity patterns associated with different elevations. This information is crucial for conservation planning and sustainable natural resource management.
The layer represents the distribution of a set of altitude ranges (classes) measured in meters above sea level (ALTIT). Each class is described through explanatory text detailing the characteristics associated with the respective altitude range (DESCP), such as coastal areas, plains, low hills, mountains, or Andean peaks. The data is derived from the Copernicus DEM elevation dataset, a Digital Surface Model (DSM) that depicts Earth's surface topography. Specifically, the GLO-30 product was used. In AmazoniaForever360+, a raster altitude layer covering northern South America was developed from this model. The original raster data was sampled and reclassified into classes relevant to agricultural development, forest management, infrastructure feasibility, accessibility, and flood risk. Based on this reclassification, the altitude and slope class layer was created.
The Copernicus DEM is managed by the European Space Agency (ESA) under the European Union’s Copernicus program, which aims to establish European Earth observation capabilities. It is a digital surface model representing the heights of natural and artificial features on Earth’s surface, including terrain, vegetation, and infrastructure. The model is primarily derived from data collected through the TanDEM-X mission, a collaboration between the German Aerospace Center (DLR) and Airbus Defence and Space, with acquisitions made between 2011 and 2015. The GLO-30 product offers global coverage at a 30-meter resolution, providing detailed worldwide data.
