Writing a feature-based processing algorithm at the example of M-value interpolation

Amongst all the processing algorithms already available in QGIS, sometimes the one thing you need is missing.  This happened not a long time ago, when we were asked to find a way to continuously visualise traffic on the Swiss motorway network (polylines) using frequently measured traffic volumes from discrete measurement stations (points) alongside the motorways. In order to keep working with the existing polylines, and be able to attribute more than one value of traffic Read more
