If you're wiling to try GRASS GIS, then the module r.slope.aspect
can output E-W and N-S derivatives using the dx=
and dy= output parameters. See:

Hi,
i'm using QGIS 3.4 on ubuntu and want to categorize some data using hstore.
i was told (*) to use *map_get(hstore_to_map("tags"),'entrance')*, but
that does not work (for me). the result is ony one category for all nodes.
sql:
select osm_id,tags->'entrance' "tags->'entrance'"

Hi Lee,
I had the same issue:

Could you open a ticket for GFS and an example file?

Hello everybody,
I’m fairly new to QGIS but I’m loving what I’ve encountered so far.
What I wish to do now is adding information layers to scanned geological maps
and then export them to my Garmin gpsmaps 64s so I can work with the maps in
the field.
What would be the way to do this? Is it
Hi,
QGIS core (the analysis library) do not expose such function directly, but
it does have methods to compute derivatives that are internally used by all
the "9 cells" algorithms (slope, aspect, ruggedness and hillshade) and the
derivative calculation is accelerated by OpenCL if available,
Qualche post fa mi lamentavo di non ritrovare in QGIS 3 quei plugin di QGIS
2 che per me erano dei must insostituibili, tipo Numerical Digitize o XY
Tools.
Per Numerical Digitize ho subito trovato un degno sostituto, il plugin Lat
Lon Tools, che fa tutto e di più di quello che faceva Numerical
