12017-08-09 12:50:44 UTCGOwin kindly avoid adding name values that are merely descriptions of the object (i.e. "hut"), building=house will suffice. You may add other attributes like construction material, see:
12017-08-09 12:47:47 UTCGOwin Hello. Could you say anything more about this project? Is there a web page where we can find more information?

Names of individuals (i.e. homeowners) are not normally added in openstreetmap, for reasons of privacy and security.
12017-07-26 05:07:47 UTCGOwin Hello. It's not necessary to add name=rumah in your buildings.

Do you mean something else? Is "rumah" a place name?

Just remember you're editing a live database, and there are many others using the map you get out of it.
12017-07-13 12:34:41 UTCGOwin Hello. Welcome to OpenStreetMap.

The gymnasium name you added is incomplete until you add a tag that classifies the object.

Edit the object, and while it is selected, search for "Sports Centre" in the left panel.

Save it, and you're good to go.

12017-07-08 08:42:00 UTCGOwin Kindly avoid tagging multiple buildings with a single way.
12017-07-08 05:06:32 UTCGOwin please don't forget to square (orthagonalize) the buildings you draw.
12017-07-07 00:33:46 UTCGOwin The undocumented tag "townhall:type:ph" is redundant. The local convention is simply to tag these buildings as townhall:type=village
12017-06-29 01:25:46 UTCGOwin Hello Taichi-san. I'm curious about the use of name, and tourism tags on some fire hydrants. Why is that so? Are there any historical/cultural significance to these hydrants?
22017-06-29 04:26:18 UTCMAPconcierge Hi, GOwin-san!
Thanks for your question, we are making new details documents about this data in YAMATO city.
So, this is fire hydrants, but we are adding tourism function to real object with local government(= YAMATO city). We are thinking about landmark for tourism in the city, fire hydrants and ...

If the Google translation is accurate, I agree with your observations. The OSM community has long, and strongly supported the "one feature, one element" convention for so long.

There's two more left:

Thanks. I didn't notice them. I've modified them on changeset #49977032.
12017-06-30 05:15:44 UTCGOwin Hi there. Great edits! Thanks for contributing.

Can you translate "payo ad kurba"?

Landuse is usually used to designated large tracts of land, and not at the individual level. If that's what you hoped to achieve, check out a sub-tag, place=plot
12017-06-29 03:41:40 UTCGOwin You need to add tags, like: "sport=scuba_diving", for example to map various points of interest. Otherwise the map rendered wouldn't understand what you're adding.
12017-06-29 03:39:14 UTCGOwin Thanks for adding data to the map.

You may add the tag "scuba_diving:divespot=yes" to indicate dive spots. See for details.

You may also tag reefs:

12017-06-13 05:51:40 UTCGOwin Hello. Welcome to OSM.

Changeset comments are meant to descriptive notes you leave for other mappers, to help them understand better any changes you made to the map.
12017-06-11 01:00:55 UTCGOwin Thanks for the edits!

The tag `building=government` is a proposed tag and not as mature as the equivalent `building=public` tag.

12017-06-11 00:55:11 UTCGOwin These are secondary / multi-functional shelters, and you're missing the "emergency:" prefix for tags.

Please fix. :) Thanks!

Also, "evacuation_center=yes" is deprecated.

12017-06-06 16:27:03 UTCTagaSanPedroAko Thanks for you mapping efforts for Marawi, but it would be better to use a better changeset comment for mapping buildings in Marawi.
22017-06-08 02:11:54 UTCGOwin Thanks for the continued contribution, jmbangate.

I don't see why this particular change set comment is any worse than say a blank one.

Besides, #osmphcitieschallenge is one of the oldest, active hashtags in PH mapping, largely because of this mapper.
12017-06-07 11:11:47 UTCGOwin Thanks for helping out. We appreciate the help.

Also, we received your GitHub comment.
12017-05-30 02:39:49 UTCGOwin Thank you for adding data to OSM. But please, be kind enough to edit them on your computer so they are classified correctly.

You're only generically tagging them as shop=computer.
12017-05-26 04:20:49 UTCGOwin Hi there. Kindly do not tag buildings with landuse=residential.

If you want to classify how buildings are used, you may, for example change this to `building=house` or `building=residential`, whichever is appropriate for your use case.

22017-05-26 03:48:35 UTCGOwin typo: `1building=residential` should read as `building=residential`
12017-05-23 03:50:41 UTCTagaSanPedroAko This is certain that this is mapping led by the Batangas City LGU, but better use more clear comments for other mappers to be aware of. If you have any questions, you can reply here.
22017-05-25 01:24:33 UTCGOwin Do you have contact information of the office/department leading this effort?
32017-05-25 06:16:23 UTCTagaSanPedroAko No, but that department of the LGU, the CPDO, is already the presumed department that maps missing POI's in barangays, tagging building classifications, and the like. Please see this talk-ph mailing list thread: Brad-M is perh...
42017-05-25 07:28:08 UTCGOwin Thanks! I opened a ticket here, and proposed next steps:

12017-05-23 04:16:21 UTCTagaSanPedroAko Better use clear changeset comments when doing your edits as part of the LGU-led mapping. A better comment here is "Batangas City LGU/CDPO mapping: add barangay hall of Bilogo"
22017-05-23 19:47:06 UTCGOwin Barangay halls are tagged as amenity=townhall and townhall:type=village.

For reference, refer to Philippine mapping conventions:
12017-05-12 13:26:05 UTCGOwin Hi Pons. Kamusta na kayo?

Nakita niyo na ba yung bagong imagery from DigiGlobe?

Sa right sidebar, click on background layer, then select DigiGlobe para makita at ma-compare niyo.
12017-05-08 00:54:43 UTCGOwin Hello there. These are very good contributions to OpenStreetMap. Are you connected with any organization, or is visiting waterfalls one of your past times?
12017-04-27 05:52:51 UTCupendrakarukonda Hi aquhcgudboy,

Welcome to OpenStreetMap. Instead of adding park tag to node, It would be great if you draw polygon around the park and use same tags to that. You can delete the node as it's not good to have park tag to node.Happy mapping.


22017-04-27 09:19:33 UTCGOwin @Upendra

While using a park tag on a node is not ideal, it's not a good enough reason to delete them. Some users may use a node to temporarily tag a park, when there's no available imagery in the area (i.e., cloud cover).

In this case, this person is a new mapper, and I agree with your sugges...
12017-04-18 15:08:23 UTCGOwin Hi there. May I know the source you used for these digitized features?
12017-04-16 02:19:24 UTCGOwin Hi Nate. Are you familiar with the area? Your revision doesn't fit the tag documentation: I'll revert this change set soon, unless you want to discuss your revision any further.

For recent photos of the area, see:
22017-04-16 02:21:14 UTCGOwin By the way, did you chose the `natural=wood` tag to improve the map rendering?
12017-04-14 05:44:38 UTCGOwin Great work Delbert! By the way, you don't need to add names for fire hydrants.

Type is probably more useful. You could find more information about this POI type here:

12017-04-11 00:49:15 UTCGOwin Hi Carl. Thank you for your map edits, and welcome to OpenStreetMap!

I'm especially interested in the water resource-related features you've been adding, because of a previous collaboration we've had with Cordaid. Here are the relevant tags we highlighted for them, in case you're interested: http...

12016-12-26 23:45:32 UTCGOwin why is the changeset comment a "fix me"?
12016-12-22 12:01:39 UTCGOwin This police POI doesn't look right. Can you please provide details that can support this?
12016-12-21 12:47:18 UTCGOwin Robert, when adding POIs, make sure you use the appropriate tags for them. For example the POIs you tagged as outdoor shops are more likely to be convenience stores.
12016-12-21 06:04:22 UTCGOwin Hello DarynVladi. Thank you for your edits.

I noticed that this changeset includes duplicate closed ways (buildings) in some areas, and that you're using JOSM.

JOSM would've validated this change set before you've uploaded it and avoided this situation.

Kindly rectify the affected building...
12016-12-06 12:09:40 UTCGOwin Please select the MapBox imagery from the layers menu. It has the most up-to-date imagery, compared to Bing.
12016-12-05 09:53:29 UTCGOwin Good work @Jneil02! Keep it up.
12016-12-05 07:44:11 UTCGOwin good work. please don't forget to digitize all features inside a grid, and to square / orthagonalize buildings, before hitting the "Mark as Done" button. If it's not complete, select, "Stop Mapping" instead.
12016-12-01 04:09:07 UTCGOwin Hi there. I noticed that several of your recent change sets are adding duplicated buildings in the same area, especially here:

Could you please validate with JOSM?
12016-11-27 03:50:09 UTCGOwin Hello there. Welcome to OpenStreetMap.

I've seen some of your recent edits, and I noticed that you've been tracing buildings that don't reflect the size, as seen in the imagery.

Kindly try to trace the building outlines, as accurate as possible.
12016-11-14 02:21:39 UTCGOwin Please tag as:

12016-11-12 00:57:45 UTCGOwin attractions or maritime navigation hazards?
12016-11-11 01:36:27 UTCGOwin It's nice to see you back editing again. :)
12016-11-09 04:17:11 UTCGOwin Please do not abbreviate. If this is a school, the more appropriate name is "Santo Rosario Elementary School."
12016-11-09 04:16:00 UTCGOwin please use appropriate tags. Funeral homes are tagged as
shop = funeral_directors

12016-11-08 08:04:37 UTCGOwin Nice! Good job.

12016-11-08 07:18:32 UTCzors1843 What's your point ?
22016-11-08 07:30:59 UTCGOwin If you need help using OpenStreetMap, consult the wiki. Your edits are harming live data
12016-11-08 06:27:12 UTCGOwin See
12016-11-08 06:23:03 UTCGOwin In OpenStreetMap, we encourage users to map what is on the ground, and use the appropriate tags (instead of tagging for the renderer)

A watch tower is probably best tagged as man_made=tower.

If you want to use OpenStreetMap for mock-up plans, check out Umap:
12016-11-08 05:57:40 UTCGOwin This is not a military installation, and landuse=military is inappropriate. To tag emergency helicopter landing sites, use emergency = landing_site. For designated and formal landing sites, use aeroway=helipad.

12016-10-27 07:04:50 UTCGOwin Good job! Welcome to OSM.

22016-08-17 16:17:35 UTCTagaSanPedroAko Likely these are PLDT street cabinet. They should be re-tagged as man_made=street_cabinet with street_cabinet=telecom.
12016-06-03 10:13:53 UTChighflyer74 Hello there!

All the best!
22016-06-04 01:49:46 UTCGOwin It's not required, but I suggest you don't modify it because we're using them in some hydrants as an example for the exercises.

I am familiar with the ref tag. Thank you.
32016-06-04 08:13:34 UTChighflyer74 You are welcome! Although inventing new keys is not forbidden, it is generally encouraged to use the well established keys primarily to make best use of the database. Happy mapping!

42016-01-27 09:54:04 UTCianlopez1115 There is a huge difference between railway stations and stop positions.

On one hand, railway stations are places where trains stop and pick up and/or drop off passengers, even if there are no passengers are picked up or dropped off in that station (per your point). On the other hand, stop positio...

Similar to ours there is only one railway from the map, cannot identify which is south or north bound to tag ...
62016-01-28 02:48:49 UTCvichwinn BTW Im using OSMAND+ for navigating especially outside the country. There is a feature to turn on transport stop to every railroad and road and it will be highlighted. Thats why I am seeing those 3 stop dots from baclaran to vito cruz station but the other station only 1 dot.
72016-01-28 03:52:51 UTCGOwin @vichwinn

re nodes tagged as `public_transport=stop_position` are not, at all, superfluous. It may appear like that in OsmAnd (which, btw, I use and recommend, too) but those nodes are functional and exist in the real world, and follows the OSM precept of `one feature, one element`.

92016-01-28 05:49:36 UTCGOwin Name tags are not necessary to tag features, so there is no need to add them, as is the case here.

12015-12-19 07:23:17 UTCGOwin Hi there. I'm curious. Are you using GPX track logs *or* Birdseye imagery to trace features?
22015-12-31 10:20:36 UTCmetaphysikhall Hey.. GPX tracks are made in Basecamp, over Birdseye Imagery, then exported.
32015-12-31 10:22:21 UTCmetaphysikhall Unfortunately Bing Images used by iD has less detail over many spots in this locality, so I turn to Birdseye.
42015-12-31 10:30:28 UTCGOwin Can you direct me to a link to the Terms of Use for Birdeye imagery? I'm curious about their data licensing terms.
52015-12-31 10:41:05 UTCmetaphysikhall There are several versions of Birdseye depending on the country; I can't find their Terms of Use, just the Buy page here:

But it's quite strict though; I'm still on my free 1 year subscription. It onl...
62015-12-31 11:02:14 UTCGOwin Yes, many commercial imagery providers have very strict licenses. That's why I'm curious because they may have issues with the OpenStreetMap licensing.

Can you tell me about your workflow?

Welcome to OSM!
12015-09-19 05:21:25 UTCGOwin Hi nerhael06. Welcome to OpenStreetMap.

I noticed you've been adding new roads over existing ones. If you're trying to update the street names, you can simply edit the existing roads, without having to make new ones.
12015-09-12 08:46:30 UTCGOwin If the actual building geometry is not determined from imagery, do not "guess-timate" the building. A POI to represent the feature is good enough.
12015-09-12 08:43:40 UTCGOwin where does this road lead to? Tertiary roads are often roads that leads to, and passes through another barangay. If doesn't tag it as unclassified or residential, whichever is appropriate.
12015-09-10 12:32:54 UTCGOwin Hi there! Welcome to OpenStreetMap.

Adding names is a great way to contribute data, but adding classification tags could help make the data better.

For example:
name=Orient Aviation

if this is a hangar, you could add:

If this is an office, you could simply ...
12015-09-09 04:17:40 UTCGOwin Dondee, is this a baranggay connector road? If it is, you can tag it as tertiary or unclassified, depending on how it terminates.
22015-09-09 04:18:07 UTCGOwin It definitely doesn't look like a service road.
12015-09-02 11:00:35 UTCGOwin Good job Dondee! Great to see you still editing. :)

So, is it really "Dgte" or do you mean "Dumaguete Sikad Trail 1"? It's best not use abbreviations so people from other places can easily search for them.
12015-08-26 09:02:25 UTCGOwin Hi cokie_osm. What's this polygon supposed to represent?
12015-08-26 01:21:11 UTCGOwin re operator tag. This shouldn't refer to the head of the barangay, but to the entity that operates it (i.e. "Barangay Domolog Council"), and used together with another tag: operator:type=government

12015-08-22 07:16:28 UTCGOwin Hi Dondee. When digitizing buildings, make sure that you cover just the buildings themselves and not other areas or other buildings. Each building should be digitized and tagged separately.

Daghang salamat for keeping it up, and updating the POIs!

You could try:
amenity=post_office and brand=2GO Express.
You can find the description of the tag here:

22015-07-23 04:18:19 UTCTotor Oops, it should be :
operator=2GO Express
name=2GO Express
32015-07-23 05:19:11 UTCtinicab Hi Totor, thank you, but really, i'm noosebleeding on how to tag the name 2Go Express and FedEx on this particular "point"..right now still figuring out how to apply your recommendation...hehe
42015-07-26 11:11:50 UTCGOwin amenity=post_office
brand=2GO Express;FedEx

where operator is the name of the establishment as seen in their DTI registration. Usually, these are franchised operators of the brand.

The name tag is optional, or it could be the business style of the operator.

42015-04-13 08:08:56 UTCGOwin Getting to know when you'll have new imagery is hard to say. OSM only relies on free imagery that Bing provides for tracing.
12015-02-16 13:16:25 UTCGOwin Sorry about the large bbox. Made a correction in another area, while doing another from somewhere else.
12015-02-15 00:34:06 UTCGOwin does CAP refer to College Assurance Plan?

If so, the node could be appropriately tagged as:

See here:

22015-02-15 01:52:04 UTCa_joemar Hi, yup that's correct. I might have accidentally move the icon of CAP. However, that doesn't operate for more than 10 years, due to losses. But still the building is still there.
