{ "currentVersion": 10.81, "id": 7, "name": "Inventory of Historic Sites", "type": "Feature Layer", "description": "This layer was constructed by combining several intermediate layers which were developed in April 2010 from a database constructed several years earlier by DPZ staff. On this layer almost all features are shown as planimetric shapes. A few features are shown as 220-foot diameter circles placed as closely as possible over the center of the feature. In the table, a show_as_point column identifies these features with a \"yes.\" There are also 5 linear-style features expressed as polygons. These are roads shown as 125-foot wide buffers following the centerline of the inventoried feature. All features appear only once in the layer except for Great Falls Park Historic District Park, which is split into two polygons, one for the portion in Upper Potomac Planning District and one for the portion in McLean Planning District.Contact: Daniel WhiteData Accessibility: Publicly available to Fairfax County Employees and represented to citizens and the public through a number of GIS applications.Update Frequency: As neededCreation Date: April 2010Feature Set Name: DPZMGR.HISTORIC_AREASFeature Layer Name: DPZMGR.INVENTORY_OF_HISTORIC_SITES", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 102746, "latestWkid": 2283 }, "copyrightText": "The geographic data layers produced by the Government of Fairfax County, Virginia (\u201cFairfax County\u201d), and any associated maps and applications, are provided as a public resource.
