Local-maxima were identified as starting points, and regions were grown to include neighboring hexagons meeting a minimum employment density threshold within an approximate 2-mile radius. The resulting boundaries were generalized (taking into account major barrier features such as topography and freeways) and used to select SANDAG Master Geographic Reference Areas (MGRAs) by activity-weighted (population and employment) centroid. Employment centers are ranked by Tier based on total number of jobs:\n\nTier 1: 50,000 or more jobs\n\nTier 2: 25,000 to 49,999 jobs\n\nTier 3: 15,000 to 24,999 jobs\n\nTier 4: 2,500 to 14,999 jobs", "summary": "Employment Centers (outline/shaded) \u2013 identified as areas with a high concentration of employment based on SANDAG\u2019s 2016 employment inventory from Urbansim summarized to quarter-mile radius hexagons.", "title": "Employment Centers (outlines)", "tags": [ "5BM", "Regional Vision", "Employment Centers" ], "type": "Map Service", "typeKeywords": [ "Data", "Service", "Map Service", "ArcGIS Server" ], "thumbnail": "thumbnail/thumbnail.png", "url": "", "extent": [ [ -117.400765639538, 32.5387958565963 ], [ -116.692201477504, 33.3942516364714 ] ], "spatialReference": "NAD_1983_StatePlane_California_VI_FIPS_0406_Feet", "accessInformation": "SANDAG", "licenseInfo": "SANDAG Data Disclaimer: https://www.sandag.org/resources/maps_and_gis/gis_downloads/disclaimer.asp" }
