Definitions:
"Lands Managed for Conservation and Open Space" are a combination of
lands that are permanently protected open space and farmland and other
lands that are managed as "open space" as defined by North Carolina
General Statue §160A-407 (see below). For example, a wildlife
conservation area that is owned by a public or non-profit land managing
organization would count as permanently protected open space.
Farmland that is preserved under the state's Farmland Preservation Trust
Fund would count as permanently protected land. Permanently protected
lands purchased or brought under an easement beginning in January 1999
count toward the state's goal of protecting one million acres of open
space by 2009-the Million Acre Initiative. In addition, the Lands Managed
for Conservation and Open Space database includes state-owned property
that is used for recreational open space including areas reserved for
boating access.
§160A-407. Definitions. (a) For the purpose of this Part an "open space" or "open area" is any space or area (i) characterized by great natural scenic beauty or (ii) whose existing openness, natural condition, or present state of use, if retained, would enhance the present or potential value of abutting or surrounding urban development, or would maintain or enhance the conservation of natural or scenic resources. (b) For the purposes of this Part "open space" or "open area" and the "public use and enjoyment" of interests or rights in real property shall also include open space land and open space uses. The term "open space land" means any undeveloped or predominantly undeveloped land in an urban area that has value for one or more of the following purposes: (i) park and recreational purposes, (ii) conservation of land and other natural resources, or (iii) historic or scenic purposes. The term "open space uses" means any use of open space land for (i) park and recreational purposes, (ii) conservation of land and other natural resources, or (iii) historic or scenic purposes. (1963, c. 1129, s. 7; 1969, c. 35, s. 1; 1971, c. 698, s. 1.)
Lands Managed for Conservation and Open Space encompass many land categories and purposes: including but not limited to:
Parks and Greenways
Natural Hazard Mitigation ("buy-out" properties)
Watershed Protection
Farmland Preservation
Cultural and Historic Lands
State Park
State Recreation Area
State Natural Area
State Nature Preserve
State Lake
State Historic Site
State Gamelands
State Coastal Reserve
>Submerged Lands
>Public Beach & Coastal Water Access
NC Wetlands Restoration Program
Conservation Reserve Enhancement Program
National Wildlife Refuge
National Forest, National Park
NRCS Wetlands Reserve
Other Nature Preserves
Exclusions:
Not all land that has recreational, historic, scenic and natural resource
value is defined as "open space and preserved farmland" for this project.
The Lands Managed for Conservation and Open Space database does NOT
include privately owned green spaces, homeowner association green spaces,
public leases of private land, school yards, university and college campus
land, athletic fields, golf courses, utility-owned land, privately owned
forests, prison property, university campuses, research farms or military
bases. Private land that is leased or managed by the state for
gameland reserves is not included in the database and does not count
toward the Million Acre goal. These types of property all have value as
areas that are free of buildings and parking lots, but they lack the
permanency and purposes required for this project's working definitions.

These data were created for the Farmland Preservation Trust Fund and the Million Acre Initiative to establish an inventory of protected lands, open space, and preserved farmland. The goal was to create a database and GIS layer for consistency and completeness. The intended users of these data are state and federal agencies, local governments, land trusts, and other private entities that have an interest in land conservation, open space and farmland preservation. Planners, land managers, and trust funds, in particular, are in need of comprehensive data for decision-making.

This composite data layer relies on the attribute accuracy of the source files. Attributes were checked for spelling consistency (e.g., managing agency name). Five locational attributes (quad name, county, river basin, DENR region, COG region) were computed by the GIS based on the centroid of each polygon (one-to-one relationship). Acres were computed by the GIS and converted to hectares. All polygons have a unique "land_id" computed by the GIS from the metric state plane coordinates (x,y) of the center point (centroid) of the polygon. Land_id is 12-character string made up of alternating digits from each of six non-decimal x and y characters (with leading zero in y string if necessary to fill six places).
Boundaries in source files were created at a scale of 1:24,000 in most cases. Local government properties in the Triangle J region were derived from larger scale parcel boundaries in many instances. State property boundaries were created at a scale of 1:24,000 or from multiple sources on a base of 1:24,000.
In some cases, state properties were mapped at a scale of 1:100,000 and not yet edited for a base of 1:24,000. Federal properties vary in scale, from the wildlife refuge areas (1:24,000) to some of the national forest boundaries that were mapped at a scale of 1:100,000 or smaller.
Some land trust and Fish and Wildlife Service property boundaries were hand-drawn on USGS 1:24,000 scale quadrangles and then manually digitized. Easements funded by the Farmland Preservation Trust fund and Conservation Tax Credit properties were generated from deed descriptions and/or survey plats. Unique land identification numbers were created for each property and data attributes were managed in a Microsoft Access database to take advantage of relational database features and accommodate one-to-many relationships. For example, a single property may have multiple funding sources and multiple land categories. Attributes were related to the spatial data by the unique land_id.
Polygons identified as "in-holdings"-privately held property that is not protected for conservation but is surrounded by protected land-are not included in the final data layer, nor are water areas within protected areas. Some public lands are not included as open space: military bases and facilities, state university campuses, research farms, and highway corridors.
Nearly all of the state-owned lands managed for conservation and open space are included in this dataset. A few properties may have been missed because of coding anomalies in the state-owned complexes file (i.e., this project selected properties based on complex use code and would have missed properties that were not coded as one of the selected code values). For the most part, the state properties are accurate, up-to-date, and complete. Federal lands are mostly complete in this dataset, including recently mapped properties that have permanent wildlife refuge easements. Recent boundary changes may not have been included in this dataset. Note that, like state properties, a selected set of federal properties was consistent with the definition of lands managed for conservation and open space.
The Local government lands managed for conservation and open space are most complete in the Triangle region where the Triangle J Council of Governments has an active "green space" mapping program. In other parts of the state, local government recreation projects and greenways may have been missed in the absence of an intensive local data collection effort.
Private lands are incomplete owing to inconsistent mapping capability among private organizations, though the majority of properties are included in this inventory with credit to the Conservation Fund and the Land Trust for North Carolina.
Using ESRI's ARC/INFO GIS software, the data set was built for arc and polygon topology using the "build" command. The data set was then cleaned with a fuzzy tolerance of (1 meter.) Topology has not been edited since the last build or clean.

- Acknowledgement of products derived from this data set should cite the following: The boundaries of polygons in this data layer may not be consistent with the source data layers, particularly where multiple sources depicted the same property from different primary or secondary sources. Efforts have been made and will continue to be made to improve the boundaries in areas where multiple sources differ. Sources of the Lands for Conservation and Open Space data include data layers in the North Carolina Corporate Geographic Database. Earlier versions of source data sets may exist. The user must be sure to use the appropriate data set for the time period of interest. While efforts have been made to ensure that these data are accurate and reliable within the state of the art, CGIA cannot assume liability for any damages or misrepresentation caused by any inaccuracies in the data or as a result of changes to the data caused by system transfers.
