Studies using satellite data produce results indexed by latitude and longitude. The study aims to convert subnational population data into a raster of latitude/longitude quadrilateral cells to assemble a compatible terrestrial population map. The authors assigned the estimated 1994 population of 219 countries, subdivided into 19,032 polygons, to over six million five‑minute by five‑minute quadrilaterals covering the world. The project has produced a world‑wide raster of population estimates based on 1994 data, with results described to date.
"We report on a project that converted subnational population data to a raster of cells on the earth. We note that studies using satellites as collection devices yield results indexed by latitude and longitude. Thus it makes sense to assemble the terrestrial arrangement of people in a compatible manner. This alternative is explored here, using latitude/longitude quadrilaterals as bins for population information.... The results to date of putting world boundary coordinates together with estimates of the number of people are described. The estimated 1994 population of 219 countries, subdivided into 19,032 polygons, has been assigned to over six million five minute by five minute quadrilaterals covering the world."
