Description

Description from the US Census Bureau: "The Census Bureau includes landmarks such as military installations in the MAF/TIGER database for locating special features and to help enumerators during field operations. The Census Bureau adds landmark features to the database on an as-needed basis and does not attempt to ensure that all instances of a particular feature are included. For additional information about area landmarks, please see Section 3.12, Landmarks (Area and Point)."

Usage

1
military(year = NULL, ...)

Arguments

year

the data year (defaults to 2015).

...

arguments to be passed to the underlying 'load_tiger' function, which is not exported. Options include refresh, which specifies whether or not to re-download shapefiles (defaults to FALSE).

Details

This file does not include the three point landmarks identified as military installation features in the MAF/TIGER database. These point landmarks are included in the point landmark shapefile. Although almost all military installations have assigned 8-character National Standard (GNIS) codes, the Census Bureau has not loaded most of this data into the MAF/TIGER database. The 2015 military shapefiles contain few values in the ANSICODE field.
