GeoTiff Black Borders No Data Value option?

Currently when importing a skewed geotiff, the area with no data is displayed as black like:
black.png
(558.84 KiB) Not downloaded yet
in qgis for example i can select No Data Value = 0

would this be possible in AQ somehow or would i need to set something else in the geotiffs for it to display transparent when no data?

Hi,
Right now there is no such option unfortunately.
One solution would be to erase the black color after you've imported the map, as explained here: https://www.alpinequest.net/en/help/v2/ ... from_a_map
Once you've erased the black color, be sure to save your map as a favorite map so the erased color definition is saved.

Otherwise if you can share an example tiff file you've made I can see if I can make the app handle such cases.

Thanks for the file.
Next update will handle the nodata value correctly (you'll need to re-import your tiff files).
Until then you can use the workaround described above that will produce a similar result.
