This polygon featureclass depicts the boundaries of the Bureau of Land Management's (BLM's) National monuments (NMs), and National conservation areas (NCAs) in Arizona as part of the National Landscape Conservation System (NLCS) data standards. This featureclass also depicts similar land designations such as Cooperative Management and Protection Areas, Forest Reserves, and Outstanding Natural areas. The NLCS dataset is in progress as of April 30, 2019. Only the Gila Box Riparian NCA has completed the process of legal description, map creation, certification, and submittal to Congress. The remaining NMs and NCAs are awaiting the draft of legal descriptions. As legal descriptions are finalized and certified, the NLCS dataset may require updating to ensure that the spatial footprints of the NM and NCA boundary data match their respective legal descriptions. Once the boundaries are confirmed, no further changes to the NM/NCA boundary data should be made. Boundary changes can only be made through an amendment to the legal description and direct notification to Congress. With the exception of the Grand Canyon Parashant National Monument, proposed designation boundaries are included in the NLCS dataset. Please refer to process steps detailed in the Lineage section of this metadata for the efforts made by the Arizona BLM in 2019.
The National Land Conservation System (NLCS) dataset shows the boundaries of the National Monuments (NMs), National Conservation Areas (NCAs), and similar designations. Similar designations include Cooperative Management and Protection Areas, Forest Reserves, and Outstanding Natural Areas. Descriptions of each polygon type are detailed in the NLCS Implementation Guidelines (version 1.1, pg 21). The Antiquities Act of 1906 grants the President authority to designate national monuments in order to protect “objects of historic or scientific interest.” NCAs and similarly designated lands are designated by Congress to conserve, protect, enhance, and manage public lands for the benefit and enjoyment of present and future generations. In June 2000, the Bureau of Land Management (BLM) responded to growing concern over the loss of open space by creating the NLCS. The NLCS brings into a single system some of the BLM's premier designations. By putting these lands into an organized system, the BLM hopes to increase public awareness of the scientific, cultural, educational, ecological, and other values of these NM/NCA boundaries.
The Public Law (P.L.) 101-628 established Gila Box Riparian NCA; P.L. 106-538 established the Las Cienegas NCA (also Sonoita Valley Acquisition Planning District), and P.L. 100-696 established San Pedro Riparian NCA. Each of these laws required the BLM to file boundary legal descriptions and maps to Congress for each NCA. As of April 30, 2019, only the Gila Box Riparian National Conservation Area has completed legal description, map depiction, certification, and submission to Congress. All other NM/NCA have gone through review by Arizona field offices. Draft maps have been completed and are awaiting legal descriptions to be drafted with the exception of the Grand Canyon Parashant NM. All proposed boundaries are included in this dataset with the exception of the Grand Canyon Parashant NM boundary. When legal descriptions are finalized and certified, minor updates may be necessary to ensure that the geospatial depiction of the NM/NCA boundary data matches the legal descriptions, after which no further changes to the geospatial NM/NCA boundary data should be made.
The standards, format and language for the legal descriptions and boundary maps were developed during regular meetings of the NLCS Coordinator, geospatial specialists and the Cadastral Surveyors regarding Arizona NLCS data. Guidance was provided from Congressional required maps and legal boundary descriptions for the NLCS Designation Manual 6120 (March, 2010). Established through Presidential Proclamation, there is no requirement for BLM to file boundary legal descriptions or maps with Congress for the National Monument. However, the NLCS Coordinator and Cadastral Survey Chief decided that it was prudent to extend the boundary process to NMs.
A published revision of the Department Manual Part 305: Departmental Science Effects, Chapter 3: Integrity of Scientific and Scholarly Activities (305 DM 3), effective December 16, 2014, is available online at http://elips.doi.gov/ELIPS/DocView.aspx?id=4056. Scholarly information considered in Departmental decision making must be robust, of the highest quality, and the result of as rigorous scientific and scholarly processes as can be achieved. Most importantly, it must be trustworthy. This policy helps us to achieve that standard (http://www.doi.gov/scientificintegrity/index.cfm).

The NLCS NM/NCA polygon footprints are derived from the NM/NCA arcs. For each NM/NCA a proposed boundary line (arc) was prepared by a geospatial specialist. The legislative or proclamation map was the primary determinate for boundary placement. For comparative purposes these maps were digitized and georeferenced. This was particularly important as the small scale and thickness hand drawn line on the legislative map, meant that there was some latitude for interpreting the intent of boundary placement. How the boundary had been depicted and managed since the NM/NCA had been established was carefully considered. NM/NCA Management Plans were consulted for boundary descriptions and to establish which trails, range, and wildlife improvements were contained within Wilderness Areas. Master Title Plats were checked for any mineral claims or right-of-ways which might affect the boundary. These were researched for current authorization and the serial casefile noted in the NM/NCA boundary arc attribute table.
Please contact the GIS Manager for additional information on provenance, history, accuracy and quality of Arizona's state datasets.
Foundational to the this data is the expectation that it topologically align where possible and appropriate with the official published version of Bureau of Land Management (BLM) Public Land Survey System (PLSS) Cadastral National Spatial Data Infrastructure (CAD NSDI) GIS Data. The dataset is run through a series of tests to verify that the data complies with the format specified in the Data Standard. ERRORS AND INCONSISTENCIES MAY STILL BE PRESENT IN THE DATA. These tests were conducted using ESRI ArcMap 10.3. The tests consisted of checking coded values for attributes against a domain of accepted values, checking that alpha-numeric values followed a valid format, and checking that numeric values were greater than zero. For the geometry, the topology was validated; however overlaps and gaps can still be found.
This dataset is considered in progress for the information presented. Inconsistencies may still be present in the data. As of April 30, 2019, only the Gila Box Riparian National Conservation Area has completed legal description, map depiction, certification, and submission to Congress. All other NM/NCA have gone through review by Arizona field offices. Draft maps have been completed and are awaiting legal descriptions to be drafted with the exception of the Grand Canyon Parashant National Monument.
Maintenance to be performed as needed under the guidance of subject matter experts and/or NLCS leads to ensure legal descriptions and Congressional status are maintained.
This data's spatial accuracy can be found from the reliability and/or the error in X, Y coordinates contained in the PLSS Points feature class. This represents the best estimate of spatial accuracy on a point-by-point basis. In addition, proposed boundaries were reviewed by the NLCS Coordinator, Field Office Managers, Recreation Specialists, Archaeologists, and Cadastral Surveyors as appropriate.

A proposed boundary line was prepared for each NM/NCA by a GIS specialist. The legislative or proclamation map was the primary determinate for boundary placement. These boundary lines were used to derive the polygon footprint for the featureclass "nlcs_nm_nca_poly".
Small scale and thickness of hand-drawn lines on legislative maps left some latitude for interpreting the intent of boundary placement. Therefore, proclamation maps were digitized and georeferenced for comparative purposes.
The legacy management and depiction of each boundary was carefully considered. NM and NCA Management Plans were consulted for boundary descriptions and to identify trails, range improvements, and wildlife improvements contained within Wilderness Areas.

Google Earth was used to digitize the features that would eventually form the wilderness boundary. Boundary lines were tied to features on the ground whenever possible. Google image resolution allowed clear feature identification, e.g. the bases of powerline posts were identified and used to create the appropriate rights-of-way. Surveyors performed groundtruthing efforts and set monuments to establish coordinates. Coordinates derived from Google's keyhole markup language (KML) files proved accurate to surveying results. Constantly improving resolution, rapid data reload, and the ability to view in different angles and directions was advantageous. Any initial concerns over Google Earth’s lack of metadata and potential for inaccuracy were unfounded.

Angle point data were constructed for each boundary with instruction from surveyors. These angle points are described in each boundary's legal description. This process was only initiated after boundaries were approved by appropriate reviewers. NM and NCA boundary polygons are based on the boundary arcs which are segmented and attributed to define feature-level metadata.

In Arizona, each NCA/NM boundary arc is segmented and attributed to describe features which form the boundary. This data color coded and annotated was used on the Coded Copy Maps. Coded Copy Maps are a visual representation of each wilderness boundary legal description). To achieve the necessary level of description four 'AZ only' attribute fields were added to nlcs_nm-nca_arc National Data Standard attribute table. These four fields are described as follows 1. "Wilderness Name": Name assists in search of area
2. Annotation: Standard phrases describing boundary features. (e.g. "On section line" "Follows easterly edge of wash" "30ft setback from road center" etc_
3. Detail: Varied comments for additional information. (e.g. feature name, serialized case file number and row, and decision comments)
4. Source: References to documents, digitization source, and digitization date

This feature class also depicts similar land designations such as Cooperative Management and Protection Areas, Forest Reserves, and Outstanding Natural areas. The NLCS dataset is in progress as of April 30, 2019. Only the Gila Box Riparian NCA has completed the process of legal description, map creation, certification, and submittal to Congress. The remaining NMs and NCAs are awaiting the draft of legal descriptions. As legal descriptions are finalized and certified, the NLCS dataset may require updating to ensure that the spatial footprints of the NM and NCA boundary data match their respective legal descriptions. Once the boundaries are confirmed, no further changes to the NM/NCA boundary data should be made. Boundary changes can only be made through an amendment to the legal description and direct notification to Congress. With the exception of the Grand Canyon Parashant National Monument, proposed designation boundaries are included in the NLCS dataset. Please refer to process steps detailed in the Lineage section of this metadata for the efforts made by the Arizona BLM in 2019.
The National Land Conservation System (NLCS) dataset shows the boundaries of the National Monuments (NMs), National Conservation Areas (NCAs), and similar designations. Similar designations include Cooperative Management and Protection Areas, Forest Reserves, and Outstanding Natural Areas. Descriptions of each polygon type are detailed in the NLCS Implementation Guidelines (version 1.1, pg 21). The Antiquities Act of 1906 grants the President authority to designate national monuments in order to protect “objects of historic or scientific interest.” NCAs and similarly designated lands are designated by Congress to conserve, protect, enhance, and manage public lands for the benefit and enjoyment of present and future generations. In June 2000, the Bureau of Land Management (BLM) responded to growing concern over the loss of open space by creating the NLCS. The NLCS brings into a single system some of the BLM's premier designations. By putting these lands into an organized system, the BLM hopes to increase public awareness of the scientific, cultural, educational, ecological, and other values of these NM/NCA boundaries.
The Public Law (P.L.) 101-628 established Gila Box Riparian NCA; P.L. 106-538 established the Las Cienegas NCA (also Sonoita Valley Acquisition Planning District), and P.L. 100-696 established San Pedro Riparian NCA. Each of these laws required the BLM to file boundary legal descriptions and maps to Congress for each NCA. As of April 30, 2019, only the Gila Box Riparian National Conservation Area has completed legal description, map depiction, certification, and submission to Congress. All other NM/NCA have gone through review by Arizona field offices. Draft maps have been completed and are awaiting legal descriptions to be drafted with the exception of the Grand Canyon Parashant NM. All proposed boundaries are included in this dataset with the exception of the Grand Canyon Parashant NM boundary. When legal descriptions are finalized and certified, minor updates may be necessary to ensure that the geospatial depiction of the NM/NCA boundary data matches the legal descriptions, after which no further changes to the geospatial NM/NCA boundary data should be made.
The standards, format and language for the legal descriptions and boundary maps were developed during regular meetings of the NLCS Coordinator, geospatial specialists and the Cadastral Surveyors regarding Arizona NLCS data. Guidance was provided from Congressional required maps and legal boundary descriptions for the NLCS Designation Manual 6120 (March, 2010). Established through Presidential Proclamation, there is no requirement for BLM to file boundary legal descriptions or maps with Congress for the National Monument. However, the NLCS Coordinator and Cadastral Survey Chief decided that it was prudent to extend the boundary process to NMs.
This polygon feature class depicts the boundaries of the Bureau of Land Management's (BLM's) National monuments (NMs), and National conservation areas (NCAs) in Arizona as part of the National Landscape Conservation System (NLCS) data standards.

This data's spatial accuracy can be found from the reliability and/or the error in X, Y coordinates contained in the PLSS Points feature class. This represents the best estimate of spatial accuracy on a point-by-point basis. In addition, proposed boundaries were reviewed by the NLCS Coordinator, Field Office Managers, Recreation Specialists, Archaeologists, and Cadastral Surveyors as appropriate.
The NLCS NM/NCA polygon footprints are derived from the NM/NCA arcs. For each NM/NCA a proposed boundary line (arc) was prepared by a geospatial specialist. The legislative or proclamation map was the primary determinate for boundary placement. For comparative purposes these maps were digitized and georeferenced. This was particularly important as the small scale and thickness hand drawn line on the legislative map, meant that there was some latitude for interpreting the intent of boundary placement. How the boundary had been depicted and managed since the NM/NCA had been established was carefully considered. NM/NCA Management Plans were consulted for boundary descriptions and to establish which trails, range, and wildlife improvements were contained within Wilderness Areas. Master Title Plats were checked for any mineral claims or right-of-ways which might affect the boundary. These were researched for current authorization and the serial casefile noted in the NM/NCA boundary arc attribute table.
Please contact the GIS Manager for additional information on provenance, history, accuracy and quality of Arizona's state datasets.
Foundational to the this data is the expectation that it topologically align where possible and appropriate with the official published version of Bureau of Land Management (BLM) Public Land Survey System (PLSS) Cadastral National Spatial Data Infrastructure (CAD NSDI) GIS Data. The dataset is run through a series of tests to verify that the data complies with the format specified in the Data Standard. ERRORS AND INCONSISTENCIES MAY STILL BE PRESENT IN THE DATA. These tests were conducted using ESRI ArcMap 10.3. The tests consisted of checking coded values for attributes against a domain of accepted values, checking that alpha-numeric values followed a valid format, and checking that numeric values were greater than zero. For the geometry, the topology was validated; however overlaps and gaps can still be found.
This dataset is considered in progress for the information presented. Inconsistencies may still be present in the data. As of April 30, 2019, only the Gila Box Riparian National Conservation Area has completed legal description, map depiction, certification, and submission to Congress. All other NM/NCA have gone through review by Arizona field offices. Draft maps have been completed and are awaiting legal descriptions to be drafted with the exception of the Grand Canyon Parashant National Monument.
Maintenance to be performed as needed under the guidance of subject matter experts and/or NLCS leads to ensure legal descriptions and Congressional status are maintained.
This official BLM Data Management handbook contains information about how data is administered, managed, and tracked. This handbook discusses how the BLM operates with regard to data development and design, quality, metadata, and business rules. The information this resource contains also pertains to geospatial data.

A proposed boundary line was prepared for each NM/NCA by a GIS specialist. The legislative or proclamation map was the primary determinate for boundary placement. These boundary lines were used to derive the polygon footprint for the feature class "nlcs_nm_nca_poly".
Small scale and thickness of hand-drawn lines on legislative maps left some latitude for interpreting the intent of boundary placement. Therefore, proclamation maps were digitized and georeferenced for comparative purposes.
The legacy management and depiction of each boundary was carefully considered. NM and NCA Management Plans were consulted for boundary descriptions and to identify trails, range improvements, and wildlife improvements contained within Wilderness Areas.

Google Earth was used to digitize the features that would eventually form the wilderness boundary. Boundary lines were tied to features on the ground whenever possible. Google image resolution allowed clear feature identification, e.g. the bases of powerline posts were identified and used to create the appropriate rights-of-way. Surveyors performed groundtruthing efforts and set monuments to establish coordinates. Coordinates derived from Google's keyhole markup language (KML) files proved accurate to surveying results. Constantly improving resolution, rapid data reload, and the ability to view in different angles and directions was advantageous. Any initial concerns over Google Earth’s lack of metadata and potential for inaccuracy were unfounded.

Angle point data were constructed for each boundary with instruction from surveyors. These angle points are described in each boundary's legal description. This process was only initiated after boundaries were approved by appropriate reviewers. NM and NCA boundary polygons are based on the boundary arcs which are segmented and attributed to define feature-level metadata.

In Arizona, each NCA/NM boundary arc is segmented and attributed to describe features which form the boundary. This data color coded and annotated was used on the Coded Copy Maps. Coded Copy Maps are a visual representation of each wilderness boundary legal description). To achieve the necessary level of description four 'AZ only' attribute fields were added to nlcs_nm-nca_arc National Data Standard attribute table. These four fields are described as follows 1. "Wilderness Name": Name assists in search of area
2. Annotation: Standard phrases describing boundary features. (e.g. "On section line" "Follows easterly edge of wash" "30ft setback from road center" etc_
3. Detail: Varied comments for additional information. (e.g. feature name, serialized case file number and row, and decision comments)
4. Source: References to documents, digitization source, and digitization date
