Road Shapefiles

Last Updated: November 2014

These shapefiles are derived from the OpenStreetMap project, as compiled by GeoFrabrik. The state shapefiles are downloaded, clipped their state boundaries, and then merged into a massive central US roads shapefile. A 150mi radius around WSR-88D sites in the central US is used to clip out individual shapefiles for each radar site. Available shapefiles are shown on the map below. The shapefiles were downloaded from GeoFabrik in November 2014.

CloudMade Productions, the original shapefile source, is no longer used and I had to find a new provider of OSM data. Sometime between 2012 and 2014, CloudMade stopped providing this data.

*Caveat: The site-specific shapefiles can be very large, and will most certainly bog down low-end systems.

Please email me with any comments or issues.
