Metadata Update Successful!

Help and Support


The IPY-PPSA metadata repository is designed as a one-step metadata input tool that stores data on northern research projects and provides the public with information on research in their region.

There are 4 tab menus: [1] Home, [2] Community Access Map, [3] For Researchers and [4] Contacts. The Home menu provides access to Tab menus [2] and [3] as well as About the Project and Help and Support.

Community Access Map – this is a “Google Map” application that is updated when a new entry is added to the metadata database. The map will automatically zoom to the maximum geographical extent of all the projects stored in the database. By clicking on the Community Access Map tab or menu in the Home page the user is presented with a map that displays the locations of research projects. Users can view information about a research project by clicking on a map icon. This application is available to the public.

For Researchers – are applications restricted to “registered IPY-PPSA researchers”. The menu options for this application are [1] Catalog Home, [2] Search, [3] List and [4] My IPY.

  1. Catalog Home – provides instructions on how to register as a researcher on the IPY-PPSA web application
  2. Search – allows researchers to search the metadata with any text that is used to reference a project. Returns list of projects that have a reference to the search criteria.
  3. List – provides a list of all projects stored in the metadata database. Users can use two commands: [1] |View| - user can view metadata for individual projects and [2] |View in Google Earth (kml)| - this option displays the outline of the study area in Google Earth. Note – user must have Google Earth installed on their computer for this application to work.
  4. My IPY – for registered researchers this option allows users to access the following menus:

My Submissions (View Your Submissions) – View all projects submitted to the metadata database. Users can select from menu items:
|View| |View in Google Earth (kml)| |Edit|

The |Edit| menu permits updating and error correction tasks.

Add Submissions (Add your submissions) – this is the primary input menu for both the metadata and the community access map application. See following section on Metadata Inputs for details on inputs. To enter text or numeric values click box area and start typing.

Note: To get brief description of input definitions move cursor over a bold text (e.g. Originator, Publication Date, Title etc.)

Data Archiving – this application is under construction and when completed will allow researchers to archive their IPY data, using an established protocol, on a secure web server.

Default input is “None” or list of access constraints defined by the dataset owner. Input as free text.

Use constraints – indicates restrictions and legal pre-requisites for using the dataset after access is granted. These include any use constraints applied to assure protection of privacy or intellectual property and any “special” limitations on use of the dataset. Default entry is usually “None” or list of constraints defined by owner. Input as free text.

Data Quality Information

Logical Consistency Report – A report on logical consistency shall describe the fidelity of relationships encoded in the data structure of the digital spatial data. The report shall detail the tests performed and the results of the tests. Tests for permissible values may be applied to any data structure. Such a test can detect gross errors, but it does not ensure all aspects of logical consistency. Note this report refers to the internal consistency of vector data structures and indicates whether all polygons are closed and lines that cross actually intersect for most IPY projects a note on location error and indicate if measured values were within an acceptable range would suffice for this input. Input as free text. If this input is not relevant to your data enter “N/A” otherwise indicate if testing was completed on the data structures.

Completeness Report – The quality report shall include information about selection criteria, definitions used and other relevant mapping rules. For example, geometric thresholds such as minimum area or minimum width shall be reported. For IPY projects refer to Extended Attributes section. For IPY-PPSA projects enter “See Extended Attributes”.

Identification Information


Originator: U.S. Fish & Wildlife Service, National Wetlands Inventory

Publication Date: 1992

Title: Hickory


Abstract: NWI digital data files 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. When completed, the series will provide coverage for all of the contiguous United States, Hawaii, Alaska, and U.S. protectorates in the Pacific and Caribbean. The digital data as well as the hardcopy maps that were used as the source for the digital data are produced and distributed by the U.S. Fish & Wildlife Service's National Wetlands Inventory project.

Purpose: The data provide consultants, planners, and resource managers with information on wetland location and type. The data were collected to meet U.S. Fish & Wildlife Service's mandate to map the wetland and deepwater habitats of the United States.

Use Constraints: Federal, State, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. 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 FGDC Metadata Workbook - Version 2.0 5/1/00 FGDC-STD-001-1998 109 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.

Data Quality Information

Logical Consistency Report: Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Pointdata are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. 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).

Completeness Report: All photo-interpretable wetlands are mapped. In the treeless prairies, 1/4 acre wetlands are mapped. In forested areas, small open water and emergent wetlands are mapped. In general, the minimum mapping unit is from 1 to 3 acres depending on the wetland type and the scale and emulsion of the source aerial photography. In regions of the country where evergreen-forested wetlands predominate, wetlands smaller than 3 acres may not be mapped. Thus, a detailed on-the-ground and historical analysis of a single site may result in a revision of the wetland boundaries established through photographic interpretation. In addition, some small wetlands and those obscured by dense forest cover may not be included in this dataset.
