Description:
Abstract:
Center points of each aerial photograph taken during the Napa County 2002 Orthophoto project. Each point has an ID number that can be used to select the corresponding hardcopy contact sheet. The photos were captured April 22 & 23, 2002.

Purpose:
These points serve as a way to organize and reference 470 Orthophotos of Napa County. Each ID number refers to the corresponding hardcopy contact sheet.
