Smaller parcels that adjoin previously mapped parcels or represent unique features, such as a bog or state-owned boat ramp, may also be included in the data layer. Purpose: The conservation/public lands layer provides information on land ownership patterns in the state. The boundaries are approximate, and are not meant to represent legal descriptions of the parcels. Supplemental_Information: Data distribution tile: statewide Each parcel may comprise one or more tracts and thus may be represented by one or more features (polygons) in the spatial database. Multiple tracts may occur as a result of multiple acquisitions over time, single acquisitions from multiple owners, and/or a parcel that is bisected by a road or other base feature. The data are available both in personal geodatabase format (.mdb) and in shapefile format (.shp).

Process_Step: Process_Description: The development of this data layer was initiated in the early 1990's as a collaboration between the Society for the Protection of NH Forests (SPNHF), the NH Office of Strategic Initiatives (OSI), and the Earth Systems Research Center at the University of New Hampshire (ESRC). While the methodologies used to develop the data set have evolved over a period of years, the basic approach has remained relatively constant throughout this period. As of 2001/2002, the entities responsible for the development of the data set include: OSI (collection, compilation, and automation of state/federal lands), the regional planning agencies (collection, compilation, and automation of municipally-managed parcels), SPNHF (collection and compilation of Forest Society Lands), and ESRC (collection, compilation, and automation of all other protected lands, and integration of all contributions into a seamless, statewide data set). The process starts with the collection of source information (PARCELSOURCE) from agencies protecting/managing parcels in the state. Protecting agencies typically include state/federal organizations, county/municipal agencies, land trusts, watershed associations, and other non-profit organizations. The protecting entity is asked to provide the best available source map, and the associated descriptive information, to the organization responsible for parcel compilation (SPNHF, OSI, an RPA, and/or ESRC). The organization recompiling the tract/parcel information must typically re-scale the source maps to achieve the target compilation scale of 1:24,000. This is accomplished via traditional copying machines with variable reduction capabilities. (For data that is digitally transmitted (e.g. DXF/DWG files), this step is omitted.) Once the source parcel is scaled appropriately, the parcel boundaries are recompiled onto 7.5-minute quad-based mylars. Prior to the late 1990's, these mylars displayed DLG-3 source data and any existing parcels in the data base. More recently, the DOTROADS data have replaced the DLG-3 roads. During recompilation, tract/parcel boundaries that are coincident with any base features are flagged appropriately. Color codes are used to indicate whether the intended coincidence is with a base map road, surface water feature, town boundary, etc. When new parcels are mapped that share boundaries with existing tracts/parcels, the compiler must select the best boundary to utilize. In these instances, attribute data (e.g. SOURCE, ACCURACY, etc.) associated with the existing and the new parcel are reviewed, and a determination is made. The recompiled boundaries are then digitized, using standard GRANIT automation tolerances. This automation may take place at several locations (as noted above). During the digitizing phase, all flagged, coincident boundaries are replaced with the appropriate base feature from the GRANIT database. This ensures consistency of the resulting tracts/parcels with the GRANIT base layers. Boundary arcs and polygons are then coded. If the automation is handled by OSI or a regional planning agency, the new parcels are submitted to GRANIT for final review and incorporation in the statewide layer. Checkplots are generated as each quad is updated, to ensure the accuracy of the linework digitizing and arc/polygon coding. Attributes are entered and verified through visual checks and by processing against valid domains. Note that certain attributes have been added since the original template was defined. As a result, not all fields will be populated for all records. As part of the June, 2017 update, a large number of boundary updates were made to the White Mountain National Forest (WMNF) utilizing data provided by The Nature Conservancy. In addition to edits made to the WMNF itself, the updates yielded many changes to the boundaries of adjacent parcels. In Spring, 2019, NH GRANIT partnered with UNH Cooperative Extension to capture property ownership information. A new field (OWNERTYPE) was added to the database to report on the type of land ownership (e.g. state, federal, private, etc.), similar to the PPAGENTYPE field which speaks to type of protection. The primary source used to obtain ownership information was the NH parcel mosaic dataset (NH Department of Revenue Administration, February, 2019). If ownership information could not be obtained using the parcel mosaic, ownership codes were assigned if sufficient protection coding existed to make an informed decision. If still no determination could be made, the communities in which these lands were located were contacted to clarify ownership status. Further information on the derivation of the data set and the standards utilized may be obtained from the GRANIT database manager at ESRC.
