Gridded Population of the World, Version 3 (GPWv3): CoastlinesEntry ID: CIESIN_SEDAC_GPWv3_COASTLINES
Abstract: Gridded Population of the World, Version 3 (GPWv3) Coastlines are derived from the land area grid to show the outlines of pixels (cells) that contain administrative units in GPWv3. The coastlines are designed for cartographic use with the GPWv3 population raster datasets. GPWv3 is produced by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with Centro Internacional de Agricultura Tropical (CIAT).
The data are available from the Socioeconomic Data and Applications Center (SEDAC) in ESRI Shapefile (SHP) format via direct download at http://sedac.ciesin.columbia.edu/gpw/global.jsp.
Purpose: To provide a set of coastlines consistent with GPWv3 raster data for cartographic purposes.

Quality ATTRIBUTE ACCURACY REPORT: Beginning with the data for January 1982, Cooperative data were processed through a completely revised system. Relying heavily on new computer editing procedures, data have been subjected to internal consistency checks, compared against climatological limits, checked serially, and evaluated against surrounding station observations. The historical data were converted from ... existing digital files and structured into the element structure format. These data were processed through a gross value check and not the current edit system. It is NCDC's goal to bring these historical files up to the same level of quality as those from 1982 onward as resources become available. Thus, benign neglect, state of the art processing (circa 1952), and limited money/people resources have contributed toward less than optimum conditions in maintaining integrity of the digital files before 1982. Soil data were added in January 1982 with approximately 250 stations reporting soil data. Soil data before 1982 are available in DSI-9639. In January 1987, the 1982 and 1983 soil data were removed from the primary period of record data tapes. 1982-83 soil data processing problems resulted in poor data quality of the monthly soils. These data are available on a separate magnetic tape containing just 1982-83 soil data. There may be a few cases in which precipitation and temperature are in metric units but are not labeled as such in the "Element Units" field. This seems to be limited to data from the early 1960's from the U.S. Virgin Islands and Puerto Rico. Some data files contain what appears to be near duplicate records. For example, one record may contain data for January through April and show the remaining months as missing. The second record may show data for January through April as missing and the remaining months as present. The reason there are two records is that the station changed climate divisions during the year. The first record will show some division number, and the second record will show a different division number.
