I have extracted a number of holes in a layer of agriculture fields to find barrows (round features) that are located in the fields. But the layer also includes irrication canals. Is there any way that I can identify these long, narrow features so that I can delete them? They have more or less the same area as the barrows.
Do you have any tips?
I use the CircularityCalculator for these cases, it works well within the limitations of the feature's shape.
Hope this helps,

an idea could be:
1. Use the BoundsExtractor to get for instance ymin and ymax per feature.
2. Use ExpressionEvaluator to get an _result attribute that calculates the
difference between ymax and ymin.
3. Use AttributeRangeFilter to filter out all the features that have a difference of
50 for instance for the _result Attribute.
-> in my small test scenario a was able to filter out long narrow features
