Description:

Abstract:

This metadata is for the 2006 accuracy assessment points (spatial database) created from the sample points collected at Lyndon B. Johnson National Historical Park.

Purpose:

Points were collected on the ground to calculate the thematic accuracy of the vegetation map.

Supplemental_Information:

This coverage was created from field data in order to conduct a thematic accuracy assessment of the vegetation database at Lyndon B. Johnson National Historical Park.

Process_Step:

Process_Description:

Points were located using a stratified random sampling method. Portions of the methodology were derived from the USGS/NPS Vegetation Mapping Program's Accuracy Assessment Procedures. Vegetation data at each point was recorded by qualified ecologists using a standard NVC Point data collection form. Data was manually transferred to a MS Access database. Point coverage was created by importing the database into ArcView as an event theme.
