[Qgis-user] What does the "Vector Field Marker" symbol layer stand for?

[Chris Crook]

Hi

This is adapted from the Vector Field Renderer plugin - see http://htmlpreview.github.io/?https://github.com/ccrook/QGIS-VectorFieldRenderer-Plugin/blob/master/VectorFieldRenderer/index.html which provides a bit of background.  The plugin provides a lot more capability, but you should be able to get the essential idea from here.

Cheers
Chris

Hi all,

When setting a symbol for a point layer feature, one of the available marker symbol type is "vector field marker". It expects some attributes to be used and some angle/orientation settings but I couldn't figure out what it is about, what is required for the fields and which rendering I should expect.

Thanks to anyone who could shed some lights on this...
