The slight differences in coordinate assignation between different datums is not a concern for world maps or those of large regions, where such differences are reduced to imperceptibility. Wagner: Equivalent to Kavrayskiy VII vertically compressed by a factor of / As a process, we use a surface to wrap around the earth and project the latitudes and longitudes to corresponding geographical coordinates on a map.
