Hi all<div><br></div><div>upon advice from Andreas, I started a formal description of the requirements for such a feature:</div><div><br></div><div><a href="https://docs.google.com/document/d/1cDemM2m88_mbs65sYzfBbVdHI_ObOjf_i35ne3OKsRs/edit?usp=sharing">https://docs.google.com/document/d/1cDemM2m88_mbs65sYzfBbVdHI_ObOjf_i35ne3OKsRs/edit?usp=sharing</a></div><div><br></div><div>Please, anyone interested, do check, comment, add, correct,... Once we have a "final" version, I will inquire a more precise financial estimation. Then let's see how we can move forward!</div><div><br></div><div>Thanks and cheers</div><div><br></div><div>Stéphane</div><div><br><br>Le jeudi 12 janvier 2017, Stéphane Henriod <<a href="mailto:stephanebek@gmail.com">stephanebek@gmail.com</a>> a écrit :<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Alexandre<div><br></div><div>(also posting on user-)</div><div><br></div><div>I 100% agree with you and I would love to somehow give back to QGIS (I did already, but at a small scale).</div><div><br></div><div>I mostly wanted to know if I am the only one to wish for this feature. Apparently not the case: many have expressed the same wish!</div><div><br></div><div>Now funding: I would love to have a rough idea what "not very expensive" means. If there are any dev around who could have the interest / skills to implement this feature, can we somehow go concrete and work together on a feature description and tentative budget? The situation is obviously very different if we talk about 1.000 or 20.000€</div><div><br></div><div>Cheers</div><div><br></div><div>Stéphane</div><div><br></div><br>Le jeudi 12 janvier 2017, Alexandre Neto <<a href="javascript:_e(%7B%7D,'cvml','senhor.neto@gmail.com');" target="_blank">senhor.neto@gmail.com</a>> a écrit :<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hello Stéphane,<div><br></div><div>IMHO, since it seems that you are not able/willing to sponsor the feature yourself, sounds like a good opportunity for a small crowdfunding.</div><div><br></div><div>That way you would be able to contribute back to QGIS by giving your time in finding a developer able to do it, setting up the crowdfunding, advertise it, pay for part of it and so on.</div><div><br></div><div>It looks like a simple feature. it should not be very expensive (much less than an ArcGIS license for sure), and if you think many people need this, then the money will be easy to raise.</div></div><div dir="ltr"><div><br></div><div>Alexandre Neto</div></div><br><div class="gmail_quote"><div dir="ltr">Stéphane Henriod <<a>stephanebek@gmail.com</a>> escreveu no dia quarta, 11/01/2017 às 11:37:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">One last message for today (sorry for spamming!)<div><br></div><div>It seems that this feature would actually be wished by "many" people (see the ticket and the talks on user-).

I feel quite bad for asking for a new feature while not having the competences to contribute a tiny bit to its development but I really feel this is one of the few major missing features in QGIS right now (and will be happy to help on the feature requirements, the tests, etc.).</div><div><br></div><div>All the best!</div><div><br>Stéphane</div><div><br></div><div><br>Le mercredi 11 janvier 2017, Stéphane Henriod <<a>stephanebek@gmail.com</a>> a écrit :<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi again<div><br></div><div>it seems that the requirements are related (although not 100% similar) to this other open (and assigned) ticket: <a href="http://hub.qgis.org/issues/14449" target="_blank">http://hub.qgis.org/issues/144<wbr>49</a></div><div><br></div><div>I really hope to see this very needed feature in a coming version of QGIS and happy to help wherever I can!</div><div><br></div><div>Cheers</div><div><br></div><div>Stéphane</div><div><br><br>Le mardi 10 janvier 2017, Stéphane Henriod <<a>stephanebek@gmail.com</a>> a écrit :<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi<div><br></div><div>let me move here a request that has been shortly discussed on the user-mailing list:</div><div><div><a href="http://lists.osgeo.org/pipermail/qgis-user/2017-January/038793.html" target="_blank">http://lists.osgeo.org/piperma<wbr>il/qgis-user/2017-January/<wbr>038793.html</a></div><div><a href="http://lists.osgeo.org/pipermail/qgis-user/2017-January/038795.html" target="_blank">http://lists.osgeo.org/piperma<wbr>il/qgis-user/2017-January/<wbr>038795.html</a></div><div><a href="http://lists.osgeo.org/pipermail/qgis-user/2017-January/038801.html" target="_blank">http://lists.osgeo.org/piperma<wbr>il/qgis-user/2017-January/<wbr>038801.html</a></div></div><div><br></div><div>and for which a ticket is open:</div><div><a href="http://hub.qgis.org/issues/14845" target="_blank">http://hub.qgis.org/issues/148<wbr>45</a></div><div><br></div><div>I was said that some work has been done in this direction for 3.0 but I don't know if it completely covers the feature request</div><div><br></div><div>----------------------</div><div><br></div><div><div>When styling a discrete or boolean raster, there seems to be no direct method, only a few workarounds. The feature I dream of would do the following:</div><div><ul><li>A new render type "Discrete raster"</li><li>One button allows to fetch all unique values form the raster (with a warning message if there are more than XXX unique values)</li><li>A color ramp is applied by default</li><li>I can multi-select values and apply them the same style and / or the same label</li><li>I can remove values. The pixels with those values will simply not be displayed</li><li>I can save my color map and load an existing color map</li></ul><div>So pretty much like the ArcGIS implementation: <a href="http://resources.arcgis.com/en/help/main/10.1/index.html#/representing_unique_categories_such_as_land_use/009t00000074000000/" target="_blank">http://resources.arcgis.com/en<wbr>/help/main/10.1/index.html#/re<wbr>presenting_unique_categories_<wbr>such_as_land_use/009t000000740<wbr>00000/</a></div></div><div><br></div><div>The current limitations I see (in 2.14):</div><div><ul><li>The discrete values must be entered manually, which is a pain for a raster with many unique values (or if I don't know in advance what all values are)</li><li>If I click on <b>Classify</b>, QGIS will choose X values (based on the number of classes and the classification method (continuous or equal interval)), which no longer match the "exact" values of my raster. It doesn't really make sense to classify a discrete rendering</li><li>Although it is currently possible to style discrete rasters, the procedure is not really intuitive for beginners</li></ul></div><div>----------------------</div><div><br></div><div>Is this a feature that is envisioned for 3.0? Is there anything I can do to support it? (except coding it myself, since I don't have the skills for that...)</div><div><br></div><div>Thanks a lot in advance</div></div><div><br></div><div>Cheers</div><div><br></div><div>Stéphane</div><br>
