Hello Eddison,
I am not sure what source you are using for the ALOS PALSAR DEM that you are
describing. As far as I know, there is no systematically processed DEM made
from ALOS PALSAR data. There is a DEM composite that the Alaska Satellite
Facility (ASF) is using for their Radiometric
Hi John,
Here is a GitHub site with plate boundaries in several GIS formats, including
Shapefile and GeoJSON.
https://github.com/fraxen/tectonicplates
These should work with QGIS. This is from the Bird (2003) paper that is a
widely used source of tectonic plate boundaries.

Hi Walter,
I think the problem was that your iCloud folder or some other directory on the
path to the files had a space in the name. Many of the QGIS functions don't
work correctly if there is a space in any name any part of the file path.

I recently upgraded from QGIS 3.10 to 3.18.3 to get the excellent new
continuous color palette plotting for map layouts. That is a huge improvement
for people like me who work with continuous datasets. Thanks to those who
implemented this!
I am getting warnings from several of the QGIS plugins
Neels,
The Worldview-3 satellite has different resolutions in the different bands.
There is a panchromatic band that has 31 cm resolution, but the multispectral
bands have 124 cm (1.2 m) resolution. You are probably seeing objects with the
panchromatic band, but NDVI has to use the coarser
Hi ajwchile,
I know of two types of geophysical files that have the .grd file extension for
gridded datasets. One is the Surfer Grid and the other is the Generic Mapping
Tools (GMT). I use GMT software all the time, and QGIS and GDAL usually have
that GMT format included as an option.

It sounds like you downloaded a new USGS product format called the GeoPDF. The
".pdf" suffix is the big clue. I don't know if QGIS 3.2.3 can read those files.
I would try downloading the map in a different format. I don't know what site
you are using, but the USGS TopoView site

Thanks, I found and installed the “AutoSaver” plugin and it seems to be
working. I am not sure how to used the “.qgz.bak” file, if I want to do that.
