latitude: Latitude
longitude: Longitude

WARNING: 55748 data points (82.37% of all data) show possible mismatch in values stored in file a and file b longitude and latitude values. Depending on the degree of mismatch, some data value comparisons in this report may be distorted or spatially nonsensical. Please consider re-running this report and including an examination of your longitude and latitude variables with appropriate epsilons in order to analyze the significance of the difference.
