Identification_Information: Citation: Citation_Information: Originator: U.S. Fish and Wildlife Service, National Wetlands Inventory Originator: Spatial Analysis Center, Yellowstone National Park Publication_Date: Unpublished Material Title: Wetlands of Yellowstone National Park, Wyoming, Montana, Idaho (NWI - point data) Geospatial_Data_Presentation_Form: map Description: Abstract: The wetlands of Yellowstone National Park are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service. This dataset is one of a series available in 7.5 minute by 7.5 minute blocks containing ground planimetric coordinates of wetlands point, line, and area features and wetlands attributes. Data were assembled and edgematched by staff at Yellowstone Park's Spatial Analysis Center to provide a seamless coverage. Purpose: Initial applications of this data have been to identify wetlands near Park roads in order to prevent their disturbance during construction and maintenance. It was not the intent of the NWI to produce maps that show exact wetland boundaries comparable to boundaries derived from ground surveys. Boundaries are therefore generalized in most cases. Consequently, the quality of the wetland data is variable mainly due to source photography, ease or difficulty of interpreting specific wetland types, and survey methods (e.g., level of field effort and state-of-the-art wetland delineation) (see section on "Completenesss_Report" for more information). Supplemental_Information: These data are associated with additional polygon and line data.

There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, State, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, State, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities. The NWI maps do not show all wetlands since the maps are derived from aerial photointerpretation with varying limitations due to scale, photo quality, inventory techniques, and other factors. Consequently, the maps tend to show wetlands that are readily photointerpreted given consideration of photo and map scale. In general, the older NWI maps prepared from 1970s-era black and white photography (1:80,000 scale) tend to be very conservative, with many forested and drier-end emergent wetlands (e.g., wet meadows) not mapped. Maps derived from color infrared photography tend to yield more accurate results except when this photography was captured during a dry year, making wetland identification equally difficult. Proper use of NWI maps therefore requires knowledge of the inherent limitations of this mapping. It is suggested that users also consult other information to aid in wetland detection, such as U.S. Department of Agriculture soil survey reports and other wetland maps that may have been produced by state and local governments, and not rely solely on NWI maps. See section on "Completeness_Report" for more information.

In addition, Wetlands Analytical Mapping System (WAMS) version 4.06 software running under the SUNOS 4.x operating system (USFWS-NWI) tests the attributes against a master set of valid wetland attributes. Also see the National Wetlands Inventory generic metadata (Quad specific metadata may be available as well): ftp:www.nwi.fws.gov/metadata/nwi_meta.txt. Logical_Consistency_Report: No duplicate features exist nor duplicate points in a data string. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data crossing the neatline are clipped to the neatline and data within a specified tolerance of the neatline are snapped to the neatline. Tests for logical consistency are performed by WAMS verification software (USFWS-NWI). Also, point topology is verified as present by ARC/INFO v8.0.1. Also see the National Wetlands Inventory generic metadata (Quad specific metadata may be available as well): ftp:www.nwi.fws.gov/metadata/nwi_meta.txt Completeness_Report: Data are complete for Yellowstone National Park. All photointerpretable wetlands are mapped given considerations of map and photo scale and state-of-the-art wetland delineation techniques. The target mapping unit is an estimate of the minimum-sized wetland that should be consistently mapped. It is not the smallest wetland that appears on the map, but instead it is the size class of the smallest group of wetlands that NWI attempts to map consistently. Users must realize however that some wetland types are conspicuous and readily identified (e.g., ponds) and smaller wetlands of these types may be mapped. Other types (drier-end wetlands and forested wetlands, especially evergreen types) are more difficult to photointerpret and larger ones may be missed. Also, users should be aware that black and white imagery tends to yield more conservative interpretations than color infrared imagery, except when the latter was acquired during a dry year, complicating wetland detection. In most areas, farmed wetlands are not mapped, with exceptions including prairie pothole-type wetlands, cranberry bogs, and diked former tidelands in the Sacramento valley. Mucklands and other farmed wetlands are usually not shown on the maps. As mentioned in the "Use_Constraints" section, no attempt was made to separate regulated wetlands from other wetlands, as these decisions must be based on criteria established by Federal and state regulatory agencies. Maps produced by photointerpretation techniques will never be as accurate as a detailed on-the-ground delineation, so the boundaries on the NWI maps should be considered generalized, especially in areas of low topographic relief (e.g., coastal plains and glaciolacustrine plains). Partly drained wetlands may also be conservatively mapped, since they may be difficult to photointerpret and in many cases, require site-specific assessment for validation.

Delineated wetland boundaries were manually transferred from interpreted photos to USGS 7.5 minute topographic quadrangle maps and then manually labelled. Quality control steps occurred throughout the photointerpretation, map compilation, and map reproduction processes. Source_Used_Citation_Abbreviation: NWI1 Source_Used_Citation_Abbreviation: NWI2 Process_Date: Ranges from 1979 to 1994 Source_Produced_Citation_Abbreviation: NWI3 Process_Step: Process_Description: Digital wetlands data were either manually digitized or scanned from stable-base copies of the 1:24,000 scale wetlands overlays registered to the standard U.S. Geological Survey (USGS) 7.5 minute quadrangles into topologically correct data files using Wetlands Analytical Mapping System (WAMS) software. Files contain ground planimetric coordinates and wetland attributes. The quadrangles were referenced to the North American Datum of 1927 (NAD27) horizontal datum. The scanning process captured the digital data at a scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station. Manual digitizing used a digitizing table to capture the digital data at a resolution of at least 0.005 inches; attribution was performed as the data were digitized. The determination of scanning versus manual digitizing production method was based on feature density, source map quality, feature symbology, and availability of production systems. The data were checked for position by comparing plots of the digital data to the source material.

The five systems include Marine (open ocean and associated coastline), Estuarine (salt marshes and brackish tidal water), Riverine (rivers, creeks, and streams), Lacustrine (lakes and deep ponds), and Palustrine (shallow ponds, marshes, swamps, sloughs) (item = ATTRIBUTE). Systems are further subdivided into subsystems which reflect hydrologic conditions. Below the subsystem is the class which describes the appearance of the wetland in terms of vegetation or substrate. Each class is further subdivided into subclasses; vegetated subclasses are described in terms of life form and substrate subclasses in terms of composition. The classification system also includes modifiers to describe hydrology (water regime), soils, water chemistry (pH, salinity), and special modifiers relating to man's activities (e.g., impounded, partly drained) (item = CATEGORY).
