Initiating Data Requests

There are two pathways to request modeling I/O and supporting data from the DW: 1. Via the Projects page, or 2. by submitting a Direct Request.

  1. Start a new Project link
    To initiate a new project on the DW, users must be registered users on the DW website, and have either "Project Manager", or "Steward" roles. Generally, these roles are assigned to users who are active members of the 3SAQS Technical Committee, and are affiliated with agencies that are identified as "3SAQS Cooperators". Cooperators include, but are not limited to, the EPA, BLM, NPS, and other groups who are approved to use 3SAQS data. The "Project" pathway is the preferred approach for obtaining 3SAQS modeling platforms for use in NEPA modeling studies. When a project is created, the project Sponsor, or Steward, can assign team members to the project. Project team members can submit data requests to the DW on behalf of the project. There can be multiple data requests associated with a project.
  2. Submit a Direct Request link
    This avenue allows general users, who may not have pre-approval by the 3-State Cooperators, to initiate data requests. This is the recommend pathway for individuals who are affiliated with universities, agencies outside the purview of the 3-State Cooperators, or other interested parties, to request data from the DW. Such requests will be sent to the 3SAQS Team for approval. If the request is approved, a DW project will be created, the request will become part of that project, and a Steward will be assigned to the project by the DW Team.

Data Request Help

When Users initiate a data request they are directed to the data request interface. A step-by-step procedure for filling out the request form can be found by following the Help link at the top of the Data Request page.

Criteria for Approval

  1. Data Selection. Use the browser to view available modeling platforms and available model I/O. Expand the tree view in the left-hand panel and add files to your request. If data are not available, this status will be indicated in the left hand panel. Requests for unavailable data can be submitted, however the will not be approved until the data have undergone review by the Three State Cooperators and are made available on the Data Warehouse.
  2. Basic parameters and supporting metadata.
    In order to be approved, each Data Request must include basic parameters (name of requestor, intended use, and other details specified on the data request form). We encourage users to either enter and/or upload supporting documents that describe the proposed modeling domain and the intended use of date in their request. We have provided two examples of external documentation provided with previous data requests as examples of the level of detail we hope to obtain as part of data requests.
    a.) example 1 (pdf) and here
    b.) example 2 (pdf).
  3. Project Sponsor (Steward).
    All data requests must have a sponsor, or steward, that is responsible to oversee a project in the DW. Stewards are individuals who are affiliated with 3SAQS cooperating agencies. A steward's role is to review the data request and to approve the request if it is determined that the request is consistent with the goals and use terms outlined in the 3SAQS data use agreement. Once a request is approved, is the responsibility of the steward to oversee the project through its life cycle. If a data request is made on behalf of a research institution or other organization outside the purview of the 3SAQS Cooperators, and a steward is not identified when the data request is submitted, the 3-State Team will review the request, and if the request is approved a steward will be assigned to the request.
  4. Data Use Agreement:
    Please read and acknowledge the Data Use Agreement that accompanies each Data Request.
