Description
Abstract: The United States Military Installations database
contains the boundaries, location, and areal
information for important military installations in the
United States and Puerto Rico. The database includes
436 polygons that represent 365 military installations.
Purpose: The data provide users with information about
the locations, names, and priority of military
installations primarily for national planning
applications.

Data Set Credit: The Military Installation Boundary files
were compiled by the Military Traffic Management Command -
Transportation Engineering Agency from a variety of sources
including the US Bureau of the Census TIGER/Line files.
Data Quality Information
Attribute Accuracy
Attribute Accuracy Report: Attributes for the military
installations database have been created using a
Geographic Information System.
Logical Consistency Report: All node-link and polygon
topological relationships are created and verified
using computer algorithms. Unique entity identifiers
were similarly verified using ARC/INFO.
Completeness Report: The data set includes information for
365 installations in the United States and Puerto Rico.
Positional Accuracy
Horizontal Positional Accuracy
Horizontal Positional Accuracy Report: The Military
installation database was compiled from TIGER/Line
data having a positional accuracy measure of +/- 80m
for the contiguous 48 States plus Washington D.C and
Hawaii. TIGER/Line files for Puerto Rico and Alaska were
compiled at a scale of 1:125,000.

Process Step
Process Description: Military installation boundaries were
added from TIGER data and topologically integrated.
The data set was checked for completeness and accuracy
in ArcInfo and was converted to shapefile.
Source Used Citation Abbreviation: TIGER
Source Produced Citation Abbreviation: MILBASE
Process Description: All military installation boundaries
were extracted from the TIGER/Line files and appended
into a single polygon shapefile.
