Is there a way to label only the largest feature of a multipart polygon?
As a workaround (unless I am missing some hidden property), is there a way, through an expression to be passed to the label engine, to label only the largest feature (in terms of area or perimeter) of a multipart polygon?
How to put labels on polygons in QGIS?
I had the same problem – QGIS was placing labels on some of the multi-polygon features inside / over the smallest polygon, while I wanted it to be centered between the two. Select the layer you are interested in labeling.
Is the label Engine of QGIS up to standard?
I am exploring the new Label engine of QGIS 2.12.2 and I found it a great improvement. However, I discover it is not yet up to ArcGIS “standard” when dealing with multipart polygons.
How to add a part to a multipart polygon?
To add a part to an existing feature, use the Continue Feature tool to digitize the new part. To remove a part from an existing multipart feature, double-click the feature with the Edit tool, right-click the part you want to delete, point to Part, then click Delete.
How do you label a convex hull layer?
Select the layer you are interested in labeling. You can select individual features, or all features. Additionally, you can edit the nodes on the convex hull layer’s features to manually control where the label appears. Update: QGIS should have this as default behavior (see my second answer).
Where do you place a marker on a polygon?
Use the Offset from edge property to move the marker in or out of the polygon. Use the Place per part property to determine how markers are placed on multipart features. Markers are placed at the ends of the line as specified by the Extremities property. Choose from Both, At begin, At end, or None.
How to divide multipart polygon into many polygons?
Your approach is almost correct. Singleparts to multipart from vector menu is (from version 2.16) using same tools as in processing toolbox, and as other processing tools from toolbox takes only selected features from input vector data by default. This can be configured in menu Processing -> Options….
How are markers placed on a multipart feature?
Use the Place per part property to determine how markers are placed on multipart features. Markers are placed at the ends of the line as specified by the Extremities property. Choose from Both, At begin, At end, or None. Orientation and offsets are set the same way as with the Along line placement. This placement is available in line symbols only.
