I got position data of underground fire hydrants from the local water
The dataset contains around 1000 hydrants, all in the area of the
municipality of Gangelt (
My plan: import the data into JOSM and check for each hydrant manually
- ... whether a hydrant already exists at the point. If yes, then match
data and make a survey if necessary
- ... whether the position of the hydrant is "plausible". If not (e.g.,
the point in question is within a house), then do not import this object
and make a survey
I briefly checked the accuracy of the position and could not find any
Because of the limited data (only position + reference number) each
object would have the tags
As can be seen, some tags, especially fire_hydrant:diameter and
fire_hydrant:position, cannot be added due to limited data.
Since I am also a member of the fire department in Gangelt, I spoke with
the head of the fire department and received encouragement for adding
the data to OSM.
In the context of the annual hydrant inspection, the data could be
verified and missing tags added.
As recommended in the import guidelines, I would create a separate user
account for the import process.
Furthermore, I will document the process in the wiki, including source
code for transforming the data.
I received permission from the data owner to add the data to OSM.
Is this a good way to go? Are there any other things I have to consider?
