Hello,<br>
<br>
Is it OK to start the import process?<br>
<br>
I slightly changed the data to import based on community feedback,
e.g., the tag "pressure=yes" is dropped (redundant for underground
hydrants in germany).<br>
<br>
<br>
Best Regards,<br>

<pre class="moz-quote-pre" wrap="">Hello all,
in the meantime I checked the data and created a wiki-page describing the planned import (unfortunately, the site is only available in german):
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Gangelt_Hydrantenimport">https://wiki.openstreetmap.org/wiki/Gangelt_Hydrantenimport</a>
There you can also find a link to the dataset that I want to import to OSM:
<a class="moz-txt-link-freetext" href="https://laumen.nrw/misc/hydranten.osm">https://laumen.nrw/misc/hydranten.osm</a>
Furthermore, I added an entry to the Import Catalogue:
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Import/Catalogue#One-Time_Imports">https://wiki.openstreetmap.org/wiki/Import/Catalogue#One-Time_Imports</a>
The user account that will be used to import the dataset: <a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/user/Michael712_imports">https://www.openstreetmap.org/user/Michael712_imports</a>
My user account: <a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/user/Michael712">https://www.openstreetmap.org/user/Michael712</a>
OSM-Wiki: <a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/User:Michael712">https://wiki.openstreetmap.org/wiki/User:Michael712</a>
Are there any other things I have to consider?
If not, I would appreciate permission to import the data.
Best Regards,
Michael

<pre class="moz-quote-pre" wrap="">Hello all,
I got position data of underground fire hydrants from the local water supply company.
The dataset contains around 1000 hydrants, all in the area of the municipality of Gangelt ( <a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/relation/158028#map=12/50.9952/6.0171">https://www.openstreetmap.org/relation/158028#map=12/50.9952/6.0171</a> ).
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 obvious problems.
Because of the limited data (only position + reference number) each object would have the tags
- emergency=fire_hydrant
- fire_hydrant:type=underground
- fire_hydrant:pressure=yes
- ref=<ref>
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?
