Changeset When Comment
148766557 almost 2 years ago

Hi there. Thanks for your edits and the addition of the service roads inside the port.

I'd like to discuss the following deletions/changes:

a) The POI node/9671880818 with amenity=coast_guard was deleted and instead the amenity=police was added in the building.

Why is this change needed? There is already a used tag for coast guard (amenity=coast_guard). It has a proposed status, but it's used in other coast guard POIs in Greece and abroad and it's more appropriate for this POI kind. If the change was done, because the amenity=coast_guard doesn't get an icon in some maps, but the police one does, I'd suggest having a read of this: osm.wiki/Tagging_for_the_renderer

b) The port's landuse tag value was changed from landuse=industrial back to landuse=harbour. You basically reverted to the 1st version that you created it. I had changed the tag to landuse=industrial because that's the recommendation on the wiki page of the tag (landuse=harbour) "Consider using rather landuse=industrial with industrial=port providing the same information in a structured way.". I have also checked how ports are tagged in other locations, and most of them use the suggested tag combination with landuse=industrial.

c) For this one, I'm less sure, but should the road inside the port be classified as secondary highway instead of just be a service road? What’s the reasoning for this change?

I look forward to your comments, fellow Corfu mapper :)

Generally the tags should follow snake-case not camel-case, so it should be ref:kep_id. Because this id is something country specific and to not conflict with something else used internationally, I suggested to namespace it with the country code using ref:GR.

Some other suggestion is that the building tag is mainly used in ways and not in nodes. If you see the building tag stats (https://taginfo.openstreetmap.org/keys/building#overview), there are 592 million ways with the building tag and only 1 million in nodes. Also the tag description in the wiki (building=government) mentions "Values of the building=* key should reflect the construction of the building, not its function". So it would be better to tag with office=government and remove the building tag (unless your tag a closed way, in that case it should be building=office).

Another thing that can be improved is that the name should not be all caps. There is an error showing up in Osmose for it ex. https://osmose.openstreetmap.fr/en/issue/d8017990-4dc5-d179-a12c-c32df15b2a88 (Name with uppercase. Concerns tag: `name=ΚΕΠ ΛΕΥΚΙΜΜΑΙΩΝ`). So I think it should be ex. "ΚΕΠ Λευκιμμαίων".

Thanks for the quick reply. Looking forward to the corrections.

About the ref tag and generally about what other tags should be used to map this, I'm going to open a thread in the OSM community forum to check what the other people opinions are related to this.

In the mean time, I'm going to combine the duplicate node that I mentioned earlier with the existing one.

Hi Pantelis,

First of all, thanks a lot for this contribution.

An issue caused by this changeset is that it created duplicate nodes in some cases, such as the KEP for Lefkimmi (an area that I monitor). I guess that there are more duplicates like this.

The duplicate entry was placed close enough but in a wrong building. Also the tags with the existing one are pretty similar:

Existing:

description=Κέντρο Εξυπηρέτησης Πολιτών (ΚΕΠ) Λευκίμμης
email=d.lefkimmaion@kep.gov.gr
fax=+302662029019
government=yes
name=Κ.Ε.Π. Λευκίμμης
office=government
phone=+302662360230
website=https://www.kep.gov.gr/

Duplicate:

addr:country=EL
addr:housenumber=222Β
addr:postcode=49080
addr:street=21ης ΜΑΡΤΙΟΥ
building=government
contact:email=d.lefkimmaion@kep.gov.gr
contact:phone=+30 2662360230
contact:website=https://www.kep.gov.gr/
kepId=0427
name:el=ΚΕΠ ΛΕΥΚΙΜΜΑΙΩΝ
name=ΚΕΠ ΛΕΥΚΙΜΜΑΙΩΝ

I think the process that created the edits should have tried to detect for existing nodes and to not create duplicate nodes but just edit the existing nodes.

Also I have a question about the kepId. Would it be better to use the ref key for it (ref=*)? How about something like "ref:GR:kep_id"?

Was this import discussed in any forum of the Greek OSM community?
