Well this could have been awesomely useful for when we were mapping townlands in #OpenStreetMap
More experiments with #OpenCV.js smart segmentation: extra polyline simplification produces cleaner shapes. Tracing map features with #Annotorious will never be the same 🚀
Although the source map images we had were... pretty rough.
Left is what we had. I've highlighted the townland border in yellow on the right. 🙂
