Question on Fix Spiky Buildings challenge

Hi Czechia OSM Community! My team in TomTom is solving spikes on buildings in Czechia. In general users creates the building polygons as per the Czech CUZK:KM carto layer. To remove the spike present on the buildings there are certain complications as follows. - As per the Czech CUZK:KM carto layer we cannot remove the spike as it is matching with the carto layer but not with the reality - According to the imagery the spike is not present which is contradicting with the Czech CUZK:KM layer Can you please advice how we can work these issues ? Example 1: Task Link: https://maproulette.org/challenge/44790/task/225696185 Way id: way 457207851 Observation: When looked into the OSM data it is found that there is a spike at (49.9735921, 16.776278). Our editor removed the way 457207850 and aligned the way 457207851 as per ground reality. *Before Data* *Data post GL Edits* *[image: pic1]* *[image: pic2]* Example 2: Task Link: https://maproulette.org/challenge/44790/task/225696167 Way id: way 553716939 Observation: When looked into the OSM data it is found that there is a spike at (49.8575, 18.2892678). Our editor modified and aligned the building polygon way 553716939 as per ground reality. *Before Data* *Data post GL Edits* *[image: pic3]* Example 3: Task Link: https://maproulette.org/challenge/44790/task/225696242 Way id: way 51800424 Observation: When looked into the OSM data it is found that there is a spike at (49.2225828, 16.5561804). Our editor modified and aligned the building polygon way 51800424 as per ground reality. *Before Fixes* *After Fixes* *Czech CUZK:KM* Thank you Michal _______________________________________________ talk-cz mailing list talk-cz na openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-cz https://openstreetmap.cz/talkcz
