Hi, I am getting QGIS crashed trying to perform the following actions: Switch the only layer in the project to edit mode. Select the spatial object comprising most of continental Europe (Portugal to Ukraine). In the advanced digitizing toolbar choose the split features option. Start tracing whe...

While the API is being completely reworked, I've also taken the opportunity to move these from being layer-wide settings to feature specific settings, so it's now possible to data - define their value on a feature-by-feature basis. Fixes #41043 Fixes qgis/QGIS#47482 Commits tagged with ...

populations only and (3) for European populations only using both climatic datasets. As a criterion of model accuracy, the receiver operating characteristic (ROC) curve and value of the area under the curve (AUC) were used71,72. The results of the analyses were visualized in QGIS 2.18.2064....
Note that the implementation has the extra feature that it will remove quotes around an argument if that makes sense (thanks to the TrimMatchingQuotes function). I believe that's part of the normal command-line interpretation. In addition to thegood and pure managed solutionbyEarwicker, it may...
I am using postGIS sql to split feature by line in JAVA, and my code worked. my code is: public List splitGeometry(String geom1, String geom2) { List<String> result=new ArrayList<String>() ; try { Statement s = connection.createStatement(); String sql_stat = null; sql_st...
Splitting features wouldn't work as I would have to zoom out to draw the line without actually knowing whether I would split the feature too "low" or too "high" without multiple trial and error. qgis polygon splitting Share Improve this question Follow edited Apr 30 at 19:29 JGH 42.7...
