Geographic Mapping

The document explains the process of creating named geographic mappings in LEAP by importing raster GIS data files, which are then used to allocate energy and emissions results to a common grid for visualization. It details supported file formats, the software's ability to automatically re-scale and normalize data, and the memory-based cell limits for 32-bit and 64-bit versions of the application. Additionally, it lists external GIS data providers such as NASA's SEDAC, ESRI, the World Resources Institute, and the United Nations Environment Programme.

• LEAP supports various GIS file formats for raster data, including GeoTIFF (GTIFF), ESRI ASCII (ASC), ESRI Binary (BIN), Multiresolution Seamless Image Database (MrSID), GIF, JPEG, STDS, and PAUX, with NetCDF (NC) support planned for a future version.
• The software automatically re-scales, clips, and normalizes imported data sets to a common resolution for the purpose of allocating energy and emissions results to the grid used in Results View.
• There are specific cell limits for map creation and display based on the software version: the 32-bit version is limited to 50 by 50 cells, while the 64-bit version supports up to 300 x 300 cells.
• The document identifies several external sources for GIS data, including NASA's Socioeconomic Data and Applications Center (SEDAC), ESRI Data & Maps, the World Resources Institute (WRI), and the United Nations Environment Programme (UNEP) Data Explorer.
