Hi Pedro, Saga is at version 2.3.1. Here attached some pixels of the datasets. According to the formula I put in the previous email, you have: a=Z_top_res.tif b=t_top_res.tif c=temp_rical.tif Thank you for your help, and for any info you can give me to help me! Eugenio

Re: [Qgis-user] Snapping: Move Features vs Node Tool

Hi Randy, I've come to accept that's just the way it is. It would be nice if the move tool did snapping. I guess it might be tricky to implement - with the node tool the cursor position and node being moved are one and the same, but with the move tool that’s not always the case. As an aside

Thanks for the discussion gentlemen. I too think your idea is a good one Karl_Magnus. Andreas, thanks for your suggestion with the info tool. I set the mode to “Top Down stop at first” long ago and hadn’t changed it since. Layer Choice works well in this situation and I didn’t realise the

Hi Matthias, sounds like exactly what I need. Unfortunately, QFieldSync depends on qgis2compat which in turn wants to use the QtTest PyQt module which apparently I do not have. Ah, my default PyQt4 was compiled and installed without QtTest, will just need to reinstall. Perhaps of interest that

Hi Andreas, You can use the QFieldSync plugin which comes with a processing algorithm that renders a styled map within a given extent to a raster dataset. Matthias On 5/31/17 6:29 PM, Andreas Plesch wrote: > Responding to myself, I found this processing script in the script > repository: > >

Responding to myself, I found this processing script in the script repository: https://github.com/qgis/QGIS-Processing/blob/master/ scripts/Create_rasters_from_canvas_for_each_vector_layer_feature_extent.py It does almost what I had in mind. Its presence indicates that indeed some Python

ind "Split off one part and add it as a new feature" is that you cannot use "Split features" to extract a whole part (workaround would be to apply "Split features" to the part and merge the two resulting new features into one, but that's not intuitive :) Bernhard

Hi Eugenio, The result with SAGA Raster Calculator seems ok here, on QGIS 2.18.9, SAGA 2.3.2, both from OSGeo4W64 (result attached). Z_top_res.tif have values from 724.403 to 1423.553, and so, the first condition is never true. Then, it always make ((b-c)/a)*1000, and the result seems ok to me.
