Im trying to download Geotiffs of MODIS true colour snapshots from the following URL:
https://wvs.earthdata.nasa.gov/?LAYERS=MODIS_Aqua_CorrectedReflectance_TrueColor,Coastlines_15m&CRS=EPSG:4326&TIME=2019-02-16&COORDINATES=-18.580076,137.249997,-14.361326,142.031249&FORMAT=image/tiff&AUTOSCALE=FALSE&RESOLUTION=250m

Recently, the downloads were saving as Geotiffs (.tiff as i need), but now they are all saving as .tif images (with no associated files) and I cant use them in spatial software.
I dont know what has changed. Can anyone help please.

Thanks for your report, and this is indeed a new issue with Worldview Snapshots. It occurs when the "Auto Scale" check box is enabled and GeoTIFF is the selected output format. In that case, the geolocation information isn't properly set.

As a temporary workaround, you can uncheck the "Auto Scale" box in the Worldview Snapshots interface, or remove the "AUTOSCALE=TRUE" part of the Worldview Snapshots image download URL.

We'll work on a fix in the meantime.

Thanks for your reply. I have tried unchecking the autoscale box and the files still download as images not Geotiffs. I have tried repeatedly.
For example, the following url:
https://wvs.earthdata.nasa.gov/?LAYERS=MODIS_Aqua_CorrectedReflectance_TrueColor&CRS=EPSG:4326&TIME=2016-03-23&COORDINATES=-18.580076,137.249997,-14.361326,142.031249&FORMAT=image/tiff&AUTOSCALE=FALSE&RESOLUTION=250m
...results in a .tif image, not a Geotiff.

Any other suggestions would be greatly appreciated. Cheers.
