Re: [GRASS-dev] r.slope.aspect with -n flag giving aspect of flat areas as -9998

2020-02-03 Thread Pedro Venâncio 
Hi Markus and Anna,

It's fixed now! Thank you very much!

The #320  part will be fixed after
the merge.

-e and -n flags are now used also in QGIS Processing Framework:
qgis/QGIS#34087 

Best regards,

Pedro

that seems to be a rounding error, even though float or double should be
able to represent - exactly. Should be easy to fix.

[GRASS-dev] r.slope.aspect with -n flag giving aspect of flat areas as -9998

2020-01-28 Thread Pedro Venâncio 
Hi all,

I was testing r.slope.aspect with the "new" -n flag, also to include -e and
-n flags in QGIS Processing, but -n flag is giving aspect values of flat
areas as -9998, instead of -, when the precision choosed is CELL, and
the output data type is CELL.

https://grass.osgeo.org/grass78/manuals/r.slope.aspect.html

I've tested with GRASS 7.6 (on Linux) and GRASS 7.8.2 (on Windows), both in
the GUI and CLI.

(Tue Jan 28 11:19:40 2020)

r.slope.aspect -e -n --verbose elevation=SRTM_PT_25m@PERMANENT
slope=SRTM_PT_25m_Slope_Deg_GRASS aspect=SRTM_PT_25m_Aspect_Std_GRASS
precision=CELL
Percent complete...
Elevation products for mapset  in 
Min computed aspect 0., max computed aspect 360.
Aspect raster map  complete
Min computed slope 0., max computed slope 75.2970
Slope raster map  complete

The elevation map I'm using is this one:
https://www.fc.up.pt/pessoas/jagoncal/srtm/SRTM_PT_25m.tif

As CELL is a 32 bit integer with a range from -2,147,483,647 to
+2,147,483,647, - should be fine to conform inside it.

Another issue I see is in
