Yes, you can make Geospatial PDF from QGIS raster maps to Avenza PDF map. If you have vector layers you can save the QGIS map to an Image (Projects > Save as Image...). Use this image as input in a Geospatial PDF convertion from menu Raster > Convertion > Translate (Convert Format)... Upload PDF to Avenza PDF Maps. I use Android, don't know the dark ...
The units of the extent will inherit from the units of the projection of the data, so to convert the extent to lat/long, you would need to reproject your data to a geographic projection (usually WGS1984) that uses degrees as units. Your data appears to have been projected to NAD27 / UTM zone 11N, which has units of meters. The extent refers to the x and y ...
I think the utility you are looking for is gdal2tiles: gdal2tiles.py input_file output_dir
I've had similar issues with gdalwarp producing black strips around image edges. Usually these happen around the international dateline, but your edges appear to be around the central meridian instead so it's no wonder you wind up with an empty strip in the middle of the output GeoTIFF. Try playing around with the -wo SOURCE_EXTRA=XXX argument. Depending ...
I don't think that Adobe Illustrator can read UInt16 data, so you have to rescale your raster first with r.rescale to 0-255 values and then export it with r.out.gdal with option type=Byte to Byte datatype.
In fact you can turn the GeoTIFF files into an OpenLayers base map with the help of MapTiler software (http://www.maptiler.com/). Once the GeoTIFF file is processed with the software on your desktop - you get a directory with JPEG/PNG tiles together with a sample viewer made using OpenLayers. Such a viewer and the folder with tiles can be uploaded to any ...
