Buildings are in offset in Lipa, Philippines #105

Open GRABOSM opened 3 years ago

GRABOSM commented 3 years ago

While working in Lipa city, we have noticed that buildings are offset and are not matching any of the available imagery sources. This is becoming challenging while adding/ modifying the missing roads in this city. (way 988191345,way 455043103)

Some examples of how the data looks there

Case1: Location: way 988191345

Note: Here the building polygons are not matching any of the imagery. There is difficulty while creating and aligning the road.

Case2: Location: way 987930879

Note: Here there is no building on-ground reality but a building polygon exists in the middle of the road.

Case3: Location: way 987652635

Note: Here the building polygon does not match on-ground reality.

Case4: Location: way 457797941

Note: Here multiple rooftops are existing in imagery but the existing building polygons are not matching in any of the available imageries.

Case5: Location: way 129386767

Note: Here a bunch of houses exists beside the road. This is challenging to create the road.

There are multiple such instances, we aren't sure about the source of imagery used in the past, some of these buildings were mapped by HOT team, maybe they can help understand this.

@maning @govvin do you have any suggestions on how do we go about it? Thank you!
