Tree canopy digitized from aerial images using a supervised image classification method. Aerial images were flown over Austin, TX in 2006 during the "leaf-on" agricultural growing season and are sourced from the U.S. Department of Agriculture's National Agriculture Imagery Program (NAIP). Data are updated every 4 years and each update is provided as a separate dataset. For historical data, search for tree canopy 2010, 2014, and 2018. The NAIP imagery resolution for 2006 is 2m (~6.6 feet). This is 4-band imagery (Red, Green, Blue, and Infrared bands) available in both true color and color-infrared. Tree canopy data is provided in both raster and vector GIS formats housed in a Geodatabase. Download and unzip the folder to get started.
