Tree canopy digitized from aerial images using a supervised image classification method. Aerial images were flown over Austin, TX in 2018 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 2006, 2010, and 2014. The NAIP imagery resolution for 2018 is 60cm (~2 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. Please note, errors may exist in this dataset due to the variation in species composition and land use found across the study area.
