a. Responses to Question #13 (What other data needs do you have to best support your planning practice/ analysis/research?) are provided in the Raw Survey Response Matrix (see attached electronic file).


Table 4h lists 21 data sets for which Gulf of Mexico coastal region respondents were asked to identify needs to support planning practice, analysis, and research.

The five data sets with the highest percentage of respondents indicating they had no need are:

  1. Bathymetric Elevation (38%);
  2. Navigational (34%);
  3. Benthic Environmental Data (28%);
  4. Marine Jurisdictional Boundaries (28%); and
  5. Archaeological/Cultural Resources (24%).

The five data sets with the highest percentage of respondents indicating they needed current data are:

  1. Land Elevation (62%);
  2. Archaeological/Cultural Resources (62%);
  3. Marine Jurisdictional Boundaries (62%);
  4. Navigational (54%); and
  5. Aerial/Satellite Imagery (52%). 

The five data sets with the highest percentage of respondents indicating they needed time-series data are:

  1. Land Cover and Land Cover Change (43%);
  2. Coastal Habitat (40%);
  3. Water Quality (37%);
  4. Shoreline Erosion (35%); and
  5. Building Quantities & Types (35%).

The five data sets with the highest percentage of respondents indicating they needed data projections are:

  1. Relative Sea Level Rise (39%);
  2. Population Counts (38%);
  3. Population Attributes (37%);
  4. Risk Management Data (32%); and
  5. Shoreline Erosion (31%).
