资源简介：

These points are directly sourced from the National Historic Landmarks, National Register, State Register, Local Historic Districts, Local Historic Places, Historic Resources inventories, CHC files, Connecticut Barns listings, Connecticut Arts & letters listings, Connecticut Making Places listings, Connecticut Freedom Trail listings, and various special surveys (Sculpture, Civil War Monuments, Municipal Parks, Town Greens, Historic Bridges). If a resource appears in multiple pdfs, it will appear as one entry.The geolocation of these points is based on the addresses and pre-existing maps that appear in the associated pdfs of the resources. Some resources were unable to be geolocated; but will still appear in the attribute table of this layer.The following is a list of the sources for each resource with their associated designation:1). National Historic Landmark (NHL); with the designation “NHL”.2). National Register (NR); with the designation “NRIND” for individual resources or NRDIS for NR Districts. A “-C” or a “-NC” is added at the end of NRIND or NRDIS to indicate if it is a contributing or non-contributing resource.3). Restricted National Register (RNR); with the designation “NRIND” for individual resources or NRDIS for NR Districts. A “-C” or a “-NC” is added at the end of NRIND or NRDIS to indicate if it is a contributing or non-contributing resource. These resources are not geolocated and their pdfs are no available to be viewed on the public viewer.4). State Register (SR); with the designation “SRIND” for individual resources or SRDIS for SR Districts. A “-C” or a “-NC” is added at the end of SRIND or SRDIS to indicate if it is a contributing or non-contributing resource. Every resource listed in the NHL or NR have a "SRIND" or "SRDIS" designation as they are automatically placed on the state register if they are added to the NHL or NR. In instances where that is the case, there will be no accompanying SR associated with it. Similarly, everything with a CHC listing, also has a SRIND designation. Some SR resources are referred to as 'LHD' within the documentation, this is because every proposed LHD pre-2019 that failed to pass LHD were automatically added to the state register.5). Local Historic Place (LHP); with the designation “LHP”.6). Local Historic District (LHD); with the designation “LHD”.7). Historic Resource Surveys (HRI)8). Survey of Outdoor Sculptures (SOS)9). Civil War Monuments (CWM)10). Municipal Parks (MP)11). Historic Bridges (HB)12). Town Greens (TG)13). Connecticut Freedom Trails (CFTs)14). Connecticut Barns (Barns)15). Creative Places16). Making Places17). Connecticut Historic Commission (CHC)18). State Owned Buildings: resources with this source were listed in the 1988 State Owned Buildings surveys and may not be reflective of present-day state-owned resources.
