The data hosted on the GeoPode site are, in part, the result of various investments by the Bill & Melinda Gates Foundation polio team in priority countries for polio eradication. They are not official or authoritative data. As the demand for accurate geospatial data has increased since the site was launched, we have also included other datasets for these countries when the quality can be verified (i.e. GRID 3 data). While we strive to maintain the highest level of accuracy possible, the data completeness and quality vary by country, and there are constant changes in placenames, boundaries, points of interest, and population; thus users should view these data as "operational" in nature and not necessarily up to date in any given situation.
