The Columbia Wetlands Air Photos project was created to acquire historical air photos of the Columbia Wetlands from 1947 and 1975 to gain a better understanding of the physical and land use changes that have occurred since the photos were taken. In addition the historical air photos will be orthorectified to create four orthomosaics from the 1947 photos and one orthomosaic from the 1975 photos Columbia Basin Trust is committed to improving the overall understanding and awareness of water related issues. CBT will commit $2400 towards the purchase of the air photos and creation of orthomosaics. This historic information will be provided to Basin residents and partners and will be used in relevant CBT publications or activities.
