Future releases will investigate the automatic generation of the bounding box coordinates from an uploaded shapefile.
North Latitude - The northern most Latitude (positive for northern hemisphere and negative values for the southern hemisphere)
South Latitude - The southern most Latitude
West Longitude - The West most Longitude (positive for locations west of the prime meridian (Greenwich) and negative values for the locations east of the prime meridian (Greenwich)
