A map service on the www that shows a comparison of USFS and Indian lands boundaries as well as an estimation of the miles of shared borders between the two organizations. This data was created by identifying the coincident lengths of border between National Forest System lands (without inholdings) and Indian Lands. The Indian Land dataset used was derived from the American Indian / Alaska Native / Native Hawaiian (AIANNH) Areas shapefile, which is from the US Census Bureau, TIGER/Line files from 2010. Only records with the following values for the AIANNHCE attribute were included in the analysis: Federally recognized legal American Indian Area (0001-4799), and American Indian Joint ? Use areas (4800-4989) *[Please see further down for more in-depth descriptions of these categories]. The National Forest System lands dataset was created by removing inholdings (based on the Forest Service?s Basic Ownership feature class) from the authoritative Forest Service?s Administrative Boundary layer in 2013. Once prepared, both the National Forest System lands file and the Indian Lands file were projected into the North_America_Lambert_Conformal_Conic projected coordinate system.Prior to the creation of the share boundaries dataset, a tolerance distance was investigated using a buffering methodology to assist in the systematic determination of coincident boundaries. The tolerance analysis was completed on identified overlapping areas of National Forest System lands and Indian Lands. The tolerance measurement used for this project was 250 meters. Thus, any boundaries having a gap or overlap with a width of less than 250 meters were considered coincident.This shared borders layer was created via a heads-up digitizing methodology using vertices within the National Forest System lands data. The following are rules that were used to facilitate systematic discernment of potentially coincident areas:Any length considered coincident between National Forest System lands and Indian Lands features was included as long as a gap or overlapping area did not exceed 250 meters wide (the accepted tolerance for this project).When a gap existed between an Indian Land and the associated National Forest System lands boundary at the position the Indian Land boundary ended, a line was manually drawn from the end of the Indian Land feature across the gap to intersect the National Forest System lands boundary. The intersection of the drawn line and the National Forest System lands boundary became a terminus of the shared border for that pairing.Digitized shared borders along National Forest System lands were extended beyond the end of a coincident Indian Land boundary if the extended area was less than or equal to 250 meters. Borders that could have been considered coincident (based on overlapping) that were perpendicular to the end of a Indian Land boundary were kept if the distance was greater than 250 meters.Gaps with a width of less than 250 meters were excluded if they were identified as an inholding based on the Forest Service?s Basic_Ownership layer. If an area of complete overlap between both the National Forest System lands and Indian Lands, had a least one dimension of greater than 250 meters, the USFS Lands border of the overlapping area was included.For full documentation, please contact individuals as specified in this metadata.*More infomration regarding the American Indian / Alaska Native / Native Hawaiian (AIANNH) Areas attribute values, used within this analysis as mentioned above: (NOTE: This information came directly from the US Census Bureau website at the following location: http://www.census.gov/geo/reference/gtc/gtc_aiannha.html?Federally recognized legal American Indian area? American Indian reservations?Federal (federal AIRs)are areas that have been set aside by the United States for the use of tribes, the exterior boundaries of which are more particularly defined in the final tribal treaties, agreements, executive orders, federal statutes, secretarial orders, or judicial determinations. The Bureau of Indian Affairs maintains a list of all federally recognized tribal governments and makes final determination of the inventory of federal AIRs. The Census Bureau recognizes federal reservations (and associated off-reservation trust lands) as territory over which American Indian tribes have primary governmental authority. American Indian reservations can be legally described as colonies, communities, Indian colonies, Indian communities, Indian rancherias, Indian reservations, Indian villages, pueblos, rancherias, ranches, reservations, reserves, settlements, or villages. The Census Bureau contacts representatives of American Indian tribal governments to identify the boundaries for federal reservations through its annual Boundary and Annexation Survey. Federal reservations may cross state and all other area boundaries.Each federal AIR is assigned a four-digit census code ranging from 0001 through 4799 in alphabetical order of AIR names nationwide. This nation-based census code is the primary unique identifier for the AIR. Each federal AIR also is assigned a five-digit Federal Information Processing Series (FIPS) code and an eight-digit National Standard (ANSI) code. Because FIPS codes are assigned in alphabetical sequence within each state, the FIPS code will be different in each state for reservations that include territory in more than one state.?American Indian Joint-Use Area? Joint-use areas,as applied to any American Indian area by the Census Bureau, means an area that is administered jointly and/or claimed by two or more American Indian tribes. The Census Bureau designates legal joint-use areas as unique geographic entities equivalent to a reservation for the purpose of presenting statistical data. Each is assigned a national four-digit census code ranging from 4800 through 4999 based on the alphabetical sequence of each joint-use area name, a five-digit Federal Information Processing Series (FIPS) code in alphabetical order within state, and an eight-digit National Standard (ANSI) code. No joint-use areas exist in multiple states. |
