EarthDefine Releases High Resolution Tree Map for California

EarthDefine, a provider of high-resolution spatial data products, has created a seamless 1 meter resolution tree cover dataset for California. This dataset updates its previous tree map for California using the newest 2014 National Agriculture Imagery Program (NAIP) aerial imagery. The source aerial imagery was flown between May and October 2014.

The California SpatialCover Tree Canopy dataset is derived from a 6 class land cover classification for California that maps trees, impervious surfaces, bare land, water, herbaceous cover and shrubs at over 30 times the resolution of existing state level datasets for California. EarthDefine's Tree Canopy data allows users to accurately measure and understand tree cover at regional and local levels, especially in mixed urban and agricultural landscapes. The tree map can help planners assess urban tree canopy for any city in the state and also support other applications like biomass estimation, wildfire risk monitoring, studying interactions between public health and tree cover, quantification of ecosystem services and improved modeling of stormwater flows.
