Re: [Qgis-user] Question about Weighting Power value when running Grid-Inverse Distance to a Power

A power of 1 is a linear interpolation among all points in the search radius. A power of 2 causes the "closest point" in the search radius to have a slightly higher weight. A power of 4, 6 and especially 10 causes the closest point to behave like a polygonal or  theissen polygon. A powe

Re: [Qgis-user] Shortest path caching

Hi, « Is there any way to output a string from a process which you can then use as an input in another process? » I am pretty sure you can do this but I don’t use the graphical modelling. Other users will give you better advice. You could repost this specific question if you don’t get anybody

Re: [Qgis-user] Question about Weighting Power value when running Grid-Inverse Distance to a Power

Dear Colleagues, as we work on such topics ourselves, let me point out please that those 'sophisticated methods' of interpolation etc have 100% nothing to do with climate, or temperature, and such units, and likely are very misleading for outcome. One may call it 'data smearing' but not more. (S

[Qgis-user] Question about Weighting Power value when running Grid-Inverse Distance to a Power

When using the Raster -> Analysis -> Grid (Inverse Distance to a Power) At the menu just before pressing run, can somebody please explain me the effect of the "Weighting power" option in the interpolation process? I'm trying to make a temperature map based on points representing each weather st

[Qgis-user] Problem Running v.sample in QGIS 3

I am trying to run the GRASS tool v.sample in 64 bit QGIS 3.8.2 and 3.4.11 with GRASS 7.6.1, and 3.2.3 with GRASS 7.4.1 on a 64-bit Windows 10 laptop, following directions in Learn QGIS, Fourth Edition: Your step-by-step guide to the fundamental of QGIS 3.4, by Andrew Cutts and Anita Glaser (Packt

[Qgis-user] Problems with the tool: join by attributes

Hi, I want to spatially join points with individual values to a polygon grid. The resulting shapefile should have a column where the values oft the points are summed up - according to the grid cell they are found in. This simple operation works fine in QGIS 2.18 where you can click "sum" as the

[Qgis-user] QGIS metadata options ? (Thanks; re-post)

Hi there, QGIS community, very sorry, but I am still struggling with xml ISO compliant FGDC metadata in QGIS. I only see the great webpage on MetaEdit; well, except, I cannot find it in the PlugIns and the website seems to be not supported anymore; no reply upon request. http://gis-lab.info/qa/
