More "guesswork" here with phantasy straight lines. zVIS said "In extraordinary situations, each data is important" - only if its real and PREVIOUSLY checked data! You cannot publish crude guesses and then take it back when real data appear! This is bad mapping and as irritating as the fake twitter news allegedly by INVOLCAN. All false date is harmful! On the 15th OSM had to take back almost 300 m of falsely mapped lava which caused a great stir in the lokal community! Stop this method, stop misinforming locals and stick to real data!
