<ul></ul><p>I am not familiar with the etiquette of the ticketing system so sorry if I'm not posting at the right place!</p>
<p>I have the feeling that this requested feature (styling boolean or discrete rasters) is quite "basic" for a professional GIS software like QGIS. Any chance this request can get some attention? :-)</p>
<p>Thanks!</p> QGIS Application - Feature request #14845: Add an option to automatically classify discrete rasters when styling themhttps://issues.qgis.org/issues/14845?journal_id=740182017-01-06T02:26:47ZGiovanni Manghigiovanni.manghi@gmail.com

<p>I agree, there is a lot of room for improvements about discrete rasters.</p>
<p>Anyway while QGIS is fundamentally users necessity driven, do not expect someone wake up in the morning and add/fix (for free or just because) what is for you/me an important feature. Raise your concerns in the users/developers mailing lists and see if the request gains momentum and if is possible to put together a group of people willingly to support the request.</p> QGIS Application - Feature request #14845: Add an option to automatically classify discrete rasters when styling themhttps://issues.qgis.org/issues/14845?journal_id=740442017-01-08T20:03:50Zshenriod -shenriod@foo.bar
<ul></ul><p>Thanks for the hint, I will do so!</p>

<ul></ul><p>I agree this is a feature that I very much would like to see/support.</p> QGIS Application - Feature request #14845: Add an option to automatically classify discrete rasters when styling themhttps://issues.qgis.org/issues/14845?journal_id=740802017-01-10T02:04:38Zshenriod -shenriod@foo.bar

<ul></ul><p>Just a note - if you do not want colors to be interpolated, just set the interpolation type to "Exact". This will solve the issue that raster value 5 still gets rendered (as mentioned in the screenshot).</p>
<p>Also you do not need to add all the values manually, you can set min value to 1, max value to 30, number of classes to 30 and the list of colors will be populated by entries as wanted. Of course having a button to fetch all distinct values from raster would be useful...</p>
<p>Multi-selection of classes to edit or remove them would be handy.</p>
<p>In the mail to qgis-dev list you mentioned loading/saving of color maps - that's already possible, look for load/save buttons.</p> QGIS Application - Feature request #14845: Add an option to automatically classify discrete rasters when styling themhttps://issues.qgis.org/issues/14845?journal_id=742362017-01-18T07:40:05ZAndy Harfoot
