Ortho Imagery Color and IR Coeur d’Alene Tribe Frank Roberts, GIS Manager

Imagery Acquisition  The Tribe determined the need for recent color IR imagery  Hired Marshall and Associates, to assist with technical details of acquisition  Reviewed available sensors, and selected the Leica ADS40  Learned that Idaho would be flown by Farm Services Administration (FSA) using ADS40  Have worked outside of FSA with Horizons Inc, to acquire the Color IR data.

NAIP  Idaho was designated by FSA for NAIP photography  NAIP specs closely matched Tribe’s specs  Tribe bought in on NAIP project reducing our cost by over 90%  Also since NAIP will be flown for most of US this project will provide a good test bed for work that could be done in other locations

Cost Savings Original Estimate Cost after FSA Buy In Cooperators Share Final Estimated Cost to Tribe Savings $107,900$14,800$6,800$8,000$99,900
