Frequently-anticipated questions:

What does this data set describe?

Title: San Antonio Missions National Historical Park Vegetation Mapping Project - Park Boundary
Abstract:
This dataset contains polygon boundaries for all units of San Antonio Missions National Historical Park.
Supplemental_Information:
San Antonio Missions National Historical Park protects four Spanish frontier missions that were part of a colonization system that stretched across the Spanish Southwest in the 17th, 18th, 19th centuries. They include Missions San Jose, San Juan, Espada, and Concepcion. The park, containing many cultural sites along with some natural areas, was established in 1978. The park covers about 819 acres.
