US Topo Quads

Current GeoPDF (which is actually a combination of vector and raster data, but not very GIS friendly)

USDA Forest Service Quads, GeoPDF and Geotiff

• https://data.fs.usda.gov/geodata/rastergateway/states-regions/states.php
• https://www.fs.fed.us/visit/maps
• https://data.fs.usda.gov/geodata/edw/datasets.php?xmlKeyword=FSTopo has vector data, in KMZ or shapefile

Historical USGS quads from about 1890 to present

•  https://ngmdb.usgs.gov/topoview/viewer/.  Maps available as
  • KMZ (easiest option, probably adequate resolution),
  • GeoPDF (challenging option)
  • Geotiff (good option)
    • Geotiff must be untiled with GDAL
    • Geotiff must be warped to UTM with GDAL
• http://historicalmaps.arcgis.com/usgs/  (3/15/2020, could not figure out how to actually see the maps, and no good reason to use the ESRI option if the USGS version works)

DRG--Digital Raster Graphic, a scanned map.

• http://libremap.org/  (TIFF, and not much activity in quite some time)
• Also check state GIS site.

Vector alternatives

• TIGER
• OpenStreetMap
• Topo Map Data and Topo Stylesheet from https://viewer.nationalmap.gov/basic/#productSearch
  • Only ArcGIS compatible for symbolization
  • Has vector data for the 7.5 minute quads
  • Need to uncompress each into its own directory, since the file names are all the same
