Resample Data

• Shapefile: reproject shapefile or add fields to its DBF file.
• DataBase--includes shapefile DBFs.
• GDAL/OGR:
• DEM formats--can go to Geotiff or MICRODEM format, copying all files in selected directory
  • ADF directory requires GDAL
  • BIL directory
  • IMG directory requires GDAL
  • DEM (MD, CDED, USGS ASCII)  directory : overwrites the CDED DEM files (USGS ASCII); the DEMs will go from over 9 MB each to under 3 MB, and will load much faster for later use.
  • ASC files
  • TXT files
  • Convert to Geotiff (can use GEOTIFFS that have to be imported via GDAL, in which case the original files will be overwritten)
• LAS lidar
• Prep OSM files
