Corrupt geotiffs #243

Closed mattwigway closed 3 years ago

mattwigway commented 4 years ago

I just did a single point analysis locally with latest master/dev of analysis-ui, analysis-backend, and r5, got an isochrone as expected, but when I tried to download as a geotiff it produced a bad geotiff:

jentilly:boshousing matthewc$ gdalinfo bpl-broken.tif 
Warning 1: TIFFReadDirectoryCheckOrder:Invalid TIFF directory; tags are not sorted in ascending order
ERROR 1: MissingRequired:TIFF directory is missing required "StripOffsets" field
gdalinfo failed - unable to open 'bpl-broken.tif'.

The file is here.

@mattwigway Thanks for the report, we'll check it out. It's also possible the heads of UI and backend are not compatible at the moment. We're planning to do a new release within a week or so, so we'll be sure to test for this particular problem while preparing the release.

I've downloaded geotiffs recently, so this may have been a transient issue with mismatched releases. Closing for now.
