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.
