Sanborn Introduces CAD-Based Version of GIS Product 1.21.04

Sanborn's digital data set of central business districts and select commercial areas is available for 27 major U.S. cities.

Responding to customer requests for a CAD-based version of it CitySets product line, Sanborn, a geographic information system (GIS) and photogrammetry developer, announced that it has made this recently-launched product available in CAD format. A highly accurate digital data set of central business districts and select commercial areas, CitySets is available for 27 major U.S. cities.

Data contained in the CitySets product include:

  • Geographic information that meets 1"=100' National Map Accuracy Standards, including building footprints with building-specific attributes such as addresses, street centerlines and names; select geographic features and landmarks; and links to site-specific photographs
  • 3-D building solids and 3-D terrain surfaces, which, when combined, enable CitySets to be CAD-operational
  • Digital, seamless, full-resolution Sanborn fire insurance maps, which provide a variety of building-level data such as construction class and occupancy type
  • Seamless, color-balanced, digital orthophoto imagery at one-half-foot pixel resolution

There are many applications for the CAD-based product. CitySets can be used as an architectural 3-D base map to improve urban planning through visualization and simulation; it can be used for site-specific engineering tasks, to facilitating traffic planning during construction projects, to determine solar envelope/air rights, to improve line-of-sight aesthetic studies, and more.

CitySets was originally designed to be delivered only in an ESRI shape file format. With the release of this new CAD-based version, and through AutoCAD's export feature, other formats can be created, including DWG R12 through 2004, DXF, DGN, and 3DS.
