I am using QGIS 3.0.

I want to use different angle arc SVG markers depending on the data in the attribute table. For example, some points require a 60-degree marker, other a 35-degree marker etc. to give an idea of a field of view from a given point.

Just to clarify, I have 3 different fields of view, depending on the angle view of the photograph. So I want to assign a different angle arc marker depending on the angle specified in the attribute table. View_angle 62, 30, 20.

For each I want an arc marker to match the angle.

    How many classes of markers will you need? Do you have a svg-file for each?

    Do you mean different angle for values within one attribute, or between more attributes (fields)?

1 Answer 1


When you open

Layer Properties > Symbology > Rule-based

you will be able to apply custom styles to each of your's SVG markers through Rule-based symbology.

In Edit Rule mode, please chose a small icon (Data Defined Override) just on the right side of the Rotation parameter. See the example below.


With that, you will get a possibility to define the rotation angle for each feature based on the field value from your attribute table.

    as far as I understood it, the width/arc of the marker is to be set differently, not (only) its orientation.

    I think then you can simply modify the Size, Offset X,Y, or Anchor point parameters, do not you think so @Erik? Otherwise, create a unique SVG file for each unique feature.

    I thought about using geometry markers, which should be adaptable to unique features of each point.

    @Erik it makes sense to utilize the geometry generator!
