This dataset represents a county wide, true-color and near infrared orthophoto (4-band) mosaic of the Marin County Imagery study area located in Marin County, San Mateo County and San Francisco County, CA. The imagery has been mosaicked to MrSID Generation 4 format using a 20 to 1 compression ratio. The data is projected in California State Plane Zone 3, the horizontal datum is NAD83(2011) and units are in US survey feet. The acquisition flight parameters were designed to yield a native pixel resolution of less than or equal to 0.5 ft. The Orthoimagery data was collected between 6/13/2018 and 6/23/2018 for the Golden Gate National Parks Conservancy.
