Overview
The Pima Association of Governments (PAG)
and a number of local government jurisdictions participate in the Regional
Orthophoto Project which started with the 1998 project
and continues with updates every few years. Each project includes imagery and
some include elevation data.
The orthophoto projects for the various years are all different. Differences
include methods, coverage areas, elevation modeling, resolution, and spectra
(black and white or color).
The 2000 project includes:
- 6 inch resolution panchromatic (black and white) imagery of 678 sections of
selected areas in eastern Pima County.
- DTM elevation data for 673 sections of the project area.
- Contours for 673 sections of the project area.
See the PAG
2000 Project Map.
The 2000 project was data was gathered (flown) in December, 2000 and
March, 2001.
