Inconsistent metadata #77

I guess this is more an issue with the metadata catalog than with the app itself but I wouldn't know where else to report it.

The metadata (satellite acquisition date) returned when clicking or querying https://metadata.maptiles.arcgis.com/arcgis/rest/services/World_Imagery_Metadata_{map_id}/MapServer/7/query/query is occasionally incorrect. See for instance here ; first and second basemaps are clearly built from the same satellite acquisition but the first shows Maxar (WV02) image captured on May 14, 2019 while the second reports Maxar (WV02) image captured on Mar 7, 2018. The third basemap is also interesting since it returns the same acquisition date as the second one when in reality it's definitely from a different day.

Otherwise great tool :smiley:
