South America: Terrain & Seafloor 48 x 36 (Portrait Orientation)
Map elements include:
A digital elevation model of all continental terrain within the map frame. Individual publicly available tiles of terrain data were sequentially downloaded from the U.S. Geological Survey in TIFF format. Each individual tile was then stitched into a continental mosaic, then “clipped” to highly detailed coastlines. All geoprocessing was performed using ESRI’s ArcGIS Pro software.
A digital bathymetric model of the surrounding seafloor. Raw, publicly available bathymetric TIFF imagery tiles were obtained from the General Bathymetric Chart of the Oceans (GEBCO) via that National Oceanic and Atmospheric Administration (NOAA) and combined into a mosaic that fills the map frame. All seafloor geoprocessing was performed using ESRI’s ArcGIS Pro software.
A detailed depiction of:
Inland water bodies, including Australia's ubiquitous intermittent lakes and salt flats
Mountain summits with corresponding elevations in feet
Volcanic mountain summits with corresponding elevations in feet
Mountain ranges, plateaus, valleys, and other significant landforms
Islands, points, capes, and other coastal features
Deserts
National, state, and territorial capitals and significant cities scaled by population
International and subnational political boundaries
Seafloor ridges, seamount chains, basins, fracture zones, and other significant features
Pinpoint locations of significant seamounts, guyots, banks, shoals, reefs, and other submerged features
South America: Terrain & Seafloor was Ridgeline's second map to be completed in the Continental Terrain & Seafloor Series. Encompassing the southeastern quadrant of the Pacific Ring of Fire, volcanism along the Pacific Ocean, the Peru-Chile-Ecuador Trench system, and the world's longest mountain range, the Andes, are areas of particular interest. The floor of the Atlantic Ocean is revealed with complex systems of rises, troughs, and significant clusters of seamounts.
