Data Management Plan

The Ocean Uses Atlas Project is an innovative partnership between the Coastal Response Research Center (CRRC) and NOAA's Office of Ocean and Coastal Resource Management (OCRM). The Project was designed to enhance ocean management through geospatial data on the full range of significant human uses of the ocean environment from the shorelines of New Hampshire and Southern Maine to the EEZ boundary. The data were gathered from regional ocean experts and users through participatory GIS methods.

Process Steps:

• 2010-01-01 00:00:00 - Data were digitized by workshop participant groups in Durham, NH.
• 2010-01-01 00:00:00 - Data from each group were reviewed following the workshop to: a. Detail any instructions from participants to add/remove areas in post-processing b. Review GIS technician and facilitator workshop notes for any relevant data-editing comments c. Discuss any areas that might require special attention or follow up.
• 2010-02-01 00:00:00 - Data were processed by Project GIS Specialist to clean artifacts created during the live, participatory mapping process.
• 2010-02-01 00:00:00 - Underwater cable footprint imported from NOAA ENC Direct to GIS: Submarine Cable. (Citation: NOAA ENC Direct to GIS: Submarine Cable)
• 2010-02-01 00:00:00 - All polygons were clipped to the project boundary to remove land and any marine areas outside the scope of the workshop.
• 2010-02-01 00:00:00 - Use-specific procedures were performed based on participant input. This involved removing areas that were stated as not occurring beyond a certain depth or distance from shore.
• 2010-02-01 00:00:00 - A polygon-in-polygon analysis was run for each use using one quarter nautical mile squared microblocks as the zonal layer to determine the number of groups that identified a use in each grid cell.
• 2010-02-01 00:00:00 - Data normalized for each use. For the footprint and future use aspects, an analysis cell with any number greater than 0 became a 1. For dominant, if the number of workshop groups who mapped a cell as dominant was at or greater than 50% of the groups who mapped that use, the value became a 1. If only 2 or fewer groups had knowledge of dominant use for the entire area, all dominant areas were retained. All other cells became a 0, so that the final field values are binary (1= Yes, 0 = No)
• 2010-02-01 00:00:00 - Processed data was analyzed for completeness and consistency. For areas where patterns did not agree, contextual edits were made based on reviewing workshop notes or existing sources and making logical edits where appropriate.
