A configuration file was used to control the production of this report.
Please see this copy of the configuration file for details.

latitude in A: pixel_latitude
latitude in B: Latitude
longitude in A: pixel_longitude
longitude in B: Longitude
longitude/latitude comparison epsilon: 0.1

WARNING: 31 data points (0.0001054% 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.
