Possible planting space (PPS) or plantable space, estimates land available for tree planting. Data were derived using a U.S. Forest Service method called the Urban Tree Canopy assessment. This assessment determines existing tree canopy cover then finds areas where it is "biophysically feasible" to plant new trees rather than were it may be preferred. For this dataset, a “possible” planting location was determined if the location contained pervious land not covered by existing tree canopy cover, surface water, impervious surfaces, or some pervious surfaces deemed to be not plantable (e.g. baseball diamonds, golf courses, etc.). Data were derived from the following data: NAIP-derived tree canopy cover (2014), the National Hydrography Dataset, and City of Austin impervious cover planimetric data (2015). Data are updated every 4 years and each update is provided as a separate dataset. Download and unzip the folder to get started. Please note, errors may exist in this dataset due to the various source data capture years, differences in spatial resolution, and analysis methods used.
