The State of Michigan will be flown as part of the National Agricultural Imagery Program (NAIP) in Summer 2005. The flight will occur during the growing season to maximize information on agricultural crops. Data collection will be undertaken by LandAir Mapping, Inc. of Atlanta Georgia. LandAir Mapping, Inc. will utilize state of the art Leica ADS40 Airborne Digital Sensors, which are designed to rapidly collect precise imagery directly to a digital form. Once imagery has been flown, it is orthorectified, color balanced, compressed and compiled into county mosaics. These county mosaics are the first product deliverable. They will not, yet, be certified through the USDA/FSA quality check process. LandAir Mapping, Inc. will also deliver uncompressed, color balanced orthorectified quarter-quad mosaics to the USDA Aerial Photography Field Office for review. Before the imagery can be certified, it must pass through an extensive QA/QC process, which checks for image quality and positional accuracy.
NAIP specifies that a contractor must deliver either Color Infrared or Natural Color orthorectified mosaics. In addition, the NAIP contractor is eligible to sell supplementary products resulting from data acquisition. A benefit to using Leica ADS40 digital sensor is the collection of imagery in all 3 visible wavelengths, as well as near-infrared. This allows LandAir Mapping, Inc. to provide both CIR and Natural Color imagery. As a result, it is possible to purchase, independent of the NAIP contract, Natural Color imagery on a county by county basis. Furthermore, due to the mechanics of the data acquisition, it is also possible to purchase Digital Surface Models (DSMs) created as a by-product of the orthorectification process.
