This data set contains parcel boundaries and associated attribute data for communities in New Hampshire. It is compiled and managed by the NH Department of Revenue Administration to support property tax equalization activities. Data was last updated in April, 2016.The map services includes 3 layers: 1) parcel polygons with attributes; 2) parcel lines (for communities without polygon data); 3) parcel points, carrying the attributes associated with the parcel lines. Basic documentation is available here; land use codes are available here.

This data set contains parcel boundaries and associated attribute data for communities in NH. It is compiled and managed by the NH Department of Revenue Administration to support property tax equalization activities. The full project data set includes the GIS parcel mosaic layer and a linked CAMA database with approximately 50 attributes per parcel. A subset of those attributes is included here. See related document for an explanation of attribute codes. Note that attributes may not be available for all parcel polygons. In particular, they may not be available for multi-structure parcels.

This Feature Class was created in 2014 as a part of the State of Connecticut’s Policy Intergovernmental Policy Division grant to the Southern Connecticut Regional Council of Governments for the Regional Web-Based GIS program.The development of the parcel layer was started in 1998-1999 by East Coast Mapping of New Hampshire. East Coast created CAD Drawings for the Town of Wallingford generated through the digitization of Town of Wallingford’s Tax Maps. By use of stereoscopic techniques East Coast created a seamless parcel base from a 2000 aerial flight’s orthophoto’s (1x600ft scale). The CAD files and base were then given to the Wallingford’s Town Engineer who maintained the base. New England Geosystems of Middletown, CT received the CAD files from Wallingford in 2014 and converted the files to GIS format to create the parcel layer. Last Updated: April 2019

The New Hampshire Hydrography Dataset (NHHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the state's surface water drainage system. The NHHD, developed at 1:24,000 scale, is an extract from the high-resolution National Hydrography Dataset (NHD) housed at the US Geological Survey.The NHHD Shapefile Extract contains the NHDFlowline, NHDWaterbody and NHDArea feature classes from the original NHHD geodatabase. These shapefiles cover the extent of the sixteen cataloging units that intersect the State of NH, and contain reach codes for networked features, stream order, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the the Atlantic Ocean. However, because this data is no longer contained in the original geodatabase, the networking capabilities of the NHDFlowline has been lost. This dataset contains data published by USGS in April 2019.

These data were extracted from the High Resolution National Hydrography Dataset Plus (NHDPlus HR), an integrated set of geospatial data layers, including the National Hydrography Dataset (NHD), National Watershed Boundary Dataset (WBD), and 3D Elevation Program Digital Elevation Model (3DEP DEM). The NHDPlus HR combines the NHD, 3DEP DEMs, and WBD to a data suite that includes the NHD stream network with linear referencing functionality, the WBD hydrologic units, elevation-derived catchment areas for each stream segment, "value added attributes" (VAAs), and other features that enhance hydrologic data analysis and routing.

This map is to help people locate LiDAR-derived 2-ft contour data sets in New Hampshire. Both HUC 8 and HUC 10 units are displayed along with the HUC labels so that users can find which contour service covers their area of interest. For services residing on ArcGIS Online, contour services are available by HUC 10. HUC 8 services (including HUC 10 sub layers) are available in the EDP folder on nhgeodata.unh.edu/nhgeodata/rest/services.

The New Hampshire State Boundary (nh) layer provides a digital representation of the New Hampshire state boundary.It was derived from the 1:24,000-scale USGS Digital Line Graphs (DLGs).

This data set represents a 5-meter resolution LiDAR-derived percent slope layer for New Hampshire. It was generated from a statewide Esri Mosaic Dataset which comprised 8 separate LiDAR collections that covered the state as of January, 2020. The Mosaic Dataset was used as input to the ArcGIS Spatial Analyst "Slope" geoprocessing tool which calculates the percent slope for each cell of the input raster, in this case, the statewide mosaic dataset.
