Abstract:

This data set consists of wetland data source, wetland type, fractional inundation, vegetation type and soil type compiled globally at a resolution of 1 degree latitude by 1 degree longitude. The series of arrays of the wetland data base includes information for all land cells that have at least 1 percent of their area designated as wetland. The wetland data source variable has a total of seven source combinations (1-7). Wetland type codes range from 1 to 12. Fractional inundation was compiled from a series of 1:1 million scale Operational Navigation Charts. Vegetation type codes range from 1 to 178 and soil type codes range from 1 to 107.

          Global digital data bases on the distribution and environmental characteristics of natural wetlands have been archived on tape in five global 1- by 1-degree latitude/longitude arrays:

          1. Data Sources, is designated by a total of seven source combinations.
          2. Wetland Type, is classified by 12 wetlands types.
          3. Fractional Inundation, gives the inundated proportion of 1-degree cells.
          4. Vegetation Types, are designated by 178 codes.
          5. Soil Types, have 107 codes.

          The sources of information used in compilation are maps produced over a variable time frame ranging from 1971 to 1981. The data set reflects wetland distribution for the current climate.
