That will give you polygons that you can color the fill area. If you have installed the latest version of Qgis, your processing toolbox could be a mix of old and new tools. If this is the case, I would do complete reinstall deleting all the old plugins.</div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">Nicolas</div><div id="AppleMailSignature"><br>Envoyé de mon iPad</div><div><br>Le 8 sept. 2016 à 08:47, KOHLMANN Hannes [via <a href="http://osgeo.org" target="_top" rel="nofollow" link="external">OSGeo.org</a>] <<a href="/user/SendEmail.jtp?type=node&node=5284798&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>> a écrit :<br><br></div><blockquote style='border-left:2px solid #CCCCCC;padding:0 1em' type="cite"><div><meta http-equiv="Content-Type" content="text/html; charset=Windows-1252">

<p class="MsoNormal">Hello dear QGis users!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A collegue and me were wondering if it is possible to create contour lines, or more important for us, FILLED contour lines (areas) for
<u>RASTER LAYER</u> data!<o:p></o:p></p>
<p class="MsoNormal">We are both very positive that this once worked and we have done that. Now we cannot find the way to reproduce that anymore.<o:p></o:p></p>
<p class="MsoNormal">On the one hand, we thought that we had done it with the gdal-Contour tool in QGIS (Raster->Extract->Contour), but now we can’t find an option to generate filled contour areas, like<o:p></o:p></p>
<p class="MsoNormal">it is possible with the installable extension „Contour Plugin“ (which is only possible to use with a point vector layer, but this is exactly what we think that we have done to a raster layer file!).
<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo1"><span style="mso-list:Ignore">1)<span style="font:7.0pt "Times New Roman"">
</span></span>Now the question: was that ever possible to do with the gdal-contour plugin? Or not…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo1"><span style="mso-list:Ignore">2)<span style="font:7.0pt "Times New Roman"">
</span></span>On the other hand, we also tried to use the GRASS Gis algorithms r.contour.level or r.contour.step, etc in the processing toolbox, but they keep giving us the error message: „environment can only contain strings See log for more details“.
What ist he problem here? Does it have to do with the new version Grass Gis 7?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo1"><span style="mso-list:Ignore">3)<span style="font:7.0pt "Times New Roman"">
</span></span>Bottom line is: We have got a .dat file, which is a raster layer with valued pixels that we are displaying in spectral colors. Now we want to extract the contour lines and to have a color fill between those contour lines. How would you
do this – is there an easy solution, which differs from the numerous tutorials on the web, which seem to be a lot more complicated than what we actually remember to have done?<o:p></o:p></p>
<p class="MsoListParagraph"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much in advance, any answer would be very helpful!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Best regards,<o:p></o:p></p>
