Description: This is a polygon datalayer of building footprints for all 13 NH communities that fall within the Nashua Regional Planning Commission's region.Features within the the following towns were aquired from the municipality directly, with estimated year of creation in parentheses: Lyndeborough (2007), Milford (2013), Hudson (2000), Merrimack (2013), Litchfield (2005), and Nashua (2011). In these areas the data are likely to have originated via photogrammetry.Approximately one-half of the buildings in the Town of Pelham were acquired through a download from OpenStreetMap in Spring of 2014; The origins of these footprints is unknown, but there is a high degree of agreement between these features and buildings as visible on aerial imagery.For coverage in all other areas, features were created in-house in 2013 using heads-up digitizing against 2010 6-inch or 1-ft aerial imagery distributed by GRANIT. Wherever possible, buildings were created with 90 degree building corners. The NRPC buildings datalayer contains attributes to support the thematic display of certain building types. Within the Building Use Code field NRPC has identified buildings housing town-level functions, e.g. town halls, police, fire, public schools, etc. These data were developed over time by NRPC in conjunction with member communities. In 2015 NRPC received grant support from the US Department of Transportation Pipeline and Hazardous Materials Safety Administration (USDOT PHMSA) to map so-called "identified sites" in the region which are locations with large or hard-to-evacuate populations. Under this grant, NRPC confirmed its existing inventory of public schools, and also added private and charter schools in the region according to an online listing from NH Department of Education (NHDOE) listing accessed in November 2015. This listing does not contain records for post-secondary educational programs, however NRPC added large post-secondary institutions to the datalayer according to local knowledge, identifying the main administrative building for mapping. Last Update: 2018.In December 2015 accessed the NH Department of Health and Human Services (NHDHHS) Childcare Search database and mapped currently licensed home and institutional programs in the region according to this list. There were numerous school locations that also offer child-care (e.g. after-school programs); NRPC coded these locations as schools. Last Update: 2018In December 2015 NRPC consulted the NHDHHS Facilities Search database and mapped the following licensed facility types in the region: hospitals, birthing centers, and ambulatory surgery centers; residential medical facilities including nursing homes, supported residential care, residential treatment and rehab, assisted living, community residences (4+ beds), psych residential, and hospice houses; and lastly day medical service facilities including renal dialysis, physical and occupational therapy, adult day care, and educational health centers. Administrative offices, as well as locations such as labs, physician offices, and non-emergent care with presumably smaller ambulatory patient populations were excluded from mapping. Last Update: 2018.Betwen June 2018 and March 2019 NRPC tagged approximately 68 buildings as gas stations based on local knowledge.
