Description

Layer name: ORTHO_IMAGE12
Subject category: survey
Title: Photo Center Index to 2012 Regional Aerial Mapping Project Imagery
Feature Count: 24145
Feature Type: Point
Abstract: Spatial index to photo centers for multi-county 2012 Aerial Mapping Project, a 53 member consortium that collected aerial imagery for orthophoto production and other products. The layer provides photo flight information about the collected imagery. It is a reference for the raw image scans, it is not a index for tiled ortho imagery. The index shows the photo centers for all three resolution areas: 0.25 foot, 0.50 foot and 1.00 foot imagery.
Purpose: Provides spatial index to photo centers for raw aerial scans and provides time of day and date when imagery was obtained.
