Re: writing raster files produces black tifs
Thank you for the hint, I wasn´t aware of this ArcGIS behaviour concerning binary raster files. A first test was successful!

Re: No geoKeys generated when writing a geotiff
Hi,
I'm stumped. Rasterio doesn't have any native understanding of GeoTIFF geokeys. To define a dataset's georeferencing, we call GDALSetGeoTransform and GDALSetProjection and GDAL's GeoTIFF driver

Re: writing raster files produces black tifs
Hi Julius.
If I understand you correctly, this is a Arc question.
IFF the values exist in your output file. You can test by loading your results file in a new process and

Re: No geoKeys generated when writing a geotiff
Could be, but i doubt it. The other geotiffs I'm able to successfully read (geoKeys) and display inside the web application (using npm's geotiff package) are generated using professional GIS software.

Re: MODIS (HDF4) data with MemoryFile
Ahh I see. Thank you Sean & Evan for your quick responses. We will proceed with our backup plan of storing data to disk or bucket and using it from there!

Hello,
I posted the below message in the Spatial Community #mapbox slack channel, but I have yet to receive a response. I am hoping to get some information about this before I consider it a bug

Re: No geoKeys generated when writing a geotiff
Hi,
Right, the typo wouldn't make a difference since "STANDARD" is already the GDAL GeoTIFF default.
At https://github.com/geotiffjs/geotiff.js I see "Rudimentary extraction of geospatial metadata".

Re: Open EHdr raster with hdr header file from memory
This is a very elegant solution, thanks for pointing it out and thanks for the sample code! The only drawback I see is that it is not possible to access multiple products (files within the archive)

Re: No geoKeys generated when writing a geotiff
Hi,
Can you try with
geotiff_keys_flavor='STANDARD'
and see what happens? According to https://gdal.org/drivers/raster/gtiff.html#creation-options there is no "u" in the option name.

Re: Default nodata value
Hi Idan,
thanks, that's already quite useful. This is typically the kind of default values I encounter when using GDAL in the command line indeed.
This does not match the values I find when using
