The Situation & Outlook (S&O) Digital Map Database (DMD) is a digital map database comprised of point, line and area features covering the United States. DMD is used to associate virtually any type of subject matter data to the geographic infrastructure down to the address and intersection level of detail. Vector-based geography include:
• Points ... address locations, schools, hospitals, among others.
• Lines ... roads, railroads, water, among others.
• Area/polygon ... statistical area boundaries, political area boundaries, water, among others.
DMD is updated continuously and covers the United States, Puerto Rico and U.S. territorial areas.
DMD is an extension and update to the Census Bureau TIGER/Line (TLF) shapefiles. Warren Glimpse, founder of ProximityOne, developed the Columbia, MO GBF/DIME file used as the prototype for the TLF program and is developer of desktop and Web-based GIS applications/tools including CVXE GIS tools using TLF data integrated with other wide-ranging data.
The TIGER/Line files update in September 2015. New attributes from 2015 TIGER/Line files will be merged into the DMD progressively in 2015.
File Naming and Nomenclature
This section describes shapefiles and related datasets based in part on Census Bureau TLF naming procedures. TLFs are now released annually. Since most file structures, but not all, are the same from year-to-year (vintages) the characters 'year' are used as a place-holder for the actual year value. For example, the 2013 vintage all lines/edges shapefile for Harris County, TX is named as tl_2013_48201_edges.shp. In this section, the year and geocode generic name is used: tl_year_[state-county FIPS]_edges.shp.
