Description: This layer displays the core and edge forest patches related to the Urban Forest Patch Viewer app. The layer displays forest patch cover in Baltimore, MD derived from 2017/18 high resolution tree canopy data (CBPO 2022).
To identify forest area within each city, tree canopy over impervious surfaces was first subtracted from the overall tree canopy layer, including buildings and roads identified from planimetric data. Morphological spatial pattern analysis (MSPA; Vogt et al. 2007) was then used to distinguish forest patches from remaining tree canopy using an edge parameter of 15 m based on observed changes in vegetation composition and structure (Baker, unpublished data). MSPA applies the 15 m edge parameter to distinguish forest core from surrounding edges. Patches always include core areas and their surrounding edges, as well as any perforations.
