It seems that this tag is often misused to tag swimming facilities.

Feel free to help clean up this tag in your area :)

On November 1-2, 2019, I attended the State of the Map Asia for the first time. This year’s State of the Map Asia was held in Dhaka, Bangladesh. I was able to attend because thankfully I was granted a partial scholarship.

Poorly-documented tags

department=*

The department of a university, organization, business, etc. that is responsible for, associated with, or relevant to the feature being mapped.

The wiki does have some mention of this tag, but it is woefully incomplete and ill-defined.

ex.

• operator=Appalachian State University
• operator:type=public
• department=Department of Philosophy & Religion

Undocumented tags

scenic=*-related tags

scenic:name=*

The name of a way designated as a scenic way by some sort of authority, assuming this name is different from the usual/common/most signed name of it.

There’s one way using name:scenic=*, which is also not a documented tag, but scenic:name=* I feel makes more sense. scenic_name is also an option, but I think it’s better to use scenic:name=* as it makes the name be more obviously contingent on the scenic designation of the way.

ex.

• scenic:name=New River Valley Byway
• scenic:name=US 421 Scenic Byway

scenic:authority=*

The authority that designated this way as being notably scenic.

ex.

• scenic:authority=NC Scenic Byways Program

Uncommon sources

source=NC Scenic Byways 4th Edition

The North Carolina Scenic Byways Program’s handbook. You can get it for free, it’s a public domain work of the state government that allows for you to add the byway into OpenStreetMap purely based on the (very clear) directions given for each byway. Can’t recommend it enough. Buy the book itself too if you can, the program needs the money.

Thanks Telenav!

An awesome group of OpenStreetMap PH volunteers and drone enthusiasts visited Lupang Arenda in Taytay, Rizal to collect aerial and street-view imagery. With the help of Barangay Sta Ana officers, we were able to conduct the survey smoothly. I was part of the drone team and our goal was to provide high-resolution imagery for mapping buildings, roads and other attributes using OSM.

As my first urban aerial imagery collection experience, it was a trial by fire. I used to have that confidence with my skills but those unpredictable factors and unpreparedness made me question my skills as a drone pilot. It was challenging but at the end of two days, the images were collected, the high-resolution orthophoto, digital elevation models were produced and I learned to be prepared even in unpredictable times.

I started learning how to use JOSM today, and I quickly noticed some advantages over the online iD editor. The first would be the seamless editing. Since there’s no need to “stream” data, all the actions taken in the editor are slightly quicker. You also have the ability to tag multiple objects at once. I’ll continue to practise with JOSM on lower priority projects.

I found a lot of lakes in Sweden which has natural=water but not tagged with any water= tags like water=lake. Most of them (est. 98%) are lakes.

I just wrote this https://josm.openstreetmap.de/ticket/18297#ticket

This resulted in one of my biggest changesets to date: osm.org/changeset/76657579

I have now found these tags missing on 3 continents Eurasia, Africa and South America.

Note: be careful with bays like this one as these are currently tagged with natural=water and no water tag because we have no suitable it seems. I add water=bay to these because they are not closed of like lagoons.

Note2: also be careful of riverbanks not tagged with waterway=riverbank.

Note3: My current workflow is this:

1. download country or part of country (<100 mb) from geofabrik.
2. use osmconvert and osmfilter to extract the natural=water and drop water= & waterway= tags. I use .poly files to extract smaller areas from the large country files. See osm.wiki/Osmconvert#Example_using_a_polygon_file_from_polygons.openstreetmap.fr for how to do that. An example command I use is: “osmconvert sweden-191107.osm.pbf -B=norrbottens-län.poly –complete-ways –complete-multipolygons -o=out.o5m && osmfilter out.o5m –keep=”natural=water” –drop=”water=” –drop=”amenity=” –drop=”waterway=” >out.osm”
3. open the filtered .osm-file in JOSM
4. inspect all elements to see if any are clearly reservoirs and add fixme tags to uncertain ones.
5. search like this: “natural=water and -waterway=* and -water=* and -wetland=* and -sport=* and -landuse=* and -surface=* and -golf=* -fixme=* and (type:way or type:relation)” to filter out any strange water areas.
6. add water=lake to the rest and source:lake=manual review based on MAXAR

I would like better tools to do this job now that we have RelationDissolve which can “join” multipolygons we should have good tools to split as well.

See https://josm.openstreetmap.de/ticket/18295#ticket for coordinating this work

Since departing Ashgabat, I have not collected much imagery, but anticipating that I will get back into it soon, I decided to invest in a dedicated smart phone just for that purpose–nothing fancy, just something with enough RAM not to crash and able to accommodate a large SD card for storing images. The Mapillary website advises that the requirement for the Mapillary app is Android 4.0 or higher, so I bought a gently used, relatively inexpensive older model Samsung smartphone with Android 4.3. However, Google Play informed me that my newly acquired phone is incompatible with the Mapillary app since it requires Android 6.0 or higher. Google Play refused to install it, so I now have an extra Android smartphone which is essentially useless for the purpose for which I bought it!

Yes, I have pinged Mapillary and asked that its website be updated.

Very proud to have sorted: *Roads unduly segmented (i.e. one road name) *Land use that has completely changed *Road layout that has been completely started again due to the above (new road and removal of old road by road contractors) *Named streets that were unnamed and under their old name

Well, some of you may have noticed that I like to add all of the little ponds and streams.That is all true, and I will tell you why. I am a person who loves weather (as told by my name) and maps. The way I see it, maps should be as detailed as possible for multiple reasons. One of them is to forecast the exact weather. If there is water nearby, there may be patchy fog right their if conditions meet. I also add that kind of stuff because I am very picky about things, and if I see something that is not their, I will add it. I also add intermittent lakes and streams that I am 100% sure that they exist during the wet season. I am a very knowledgeable person, and you may see more of my edits over time.

OSMF board elections are taking place in December and this year there are four seats on the board to be filled so it will be a fairly significant event. Candidates for the board will be asked to nominate themselves in a few days.

Having observed the board elections during the past years with very different people putting themselves up for election and attempting to convince the OSMF members to vote for them using various strategies i thought i’d this year formulate some advise to potential candidates in advance based on my observations of the past years.

There are mainly two reasons for me doing this:

Hello, guys! October the 31st has passed, and Ladakh has officially become a union territory in India. A union territory is basically mapped with the same administrative boundaries as that of a state. If not already being mapped, should we start mapping Ladakh’s boundaries? It includes these districts: Kargil, and Leh.

I reached intermediate mapper status on HOT Tasking Manager a few days ago. Now that I’m able to take on tougher projects and validate others’ work, I think now would be a good time to “start again”: learning how to use JOSM to map instead of the online iD Editor. I’ve only used the building label for 90+% of my edits so far but I can see lots of road labellings, as well as rivers and bridges, that I should learn about if I want to become a better mapper. So far I’ve been mapping for 1 hour a day almost daily for the past 2 months. Now I will be taking it slow for a few days while I get to grips with learning a new software.

Last month I gave a presentation at the North American Cartographic Information Society (NACIS) conference about getting Native Reservations to show up on OpenStreetMap.

I blogged about this previously: “It’s about time OpenStreetMap showed native lands on the map”. Now you can watch the video of my presentation on YouTube.

You can also follow along with the slides on SpeakerDeck.

From what I can tell, OpenStreetMap lacks a tag allowing mappers to mark (yes, subjectively) roads that are unsafe for cyclists. In my opinion, this feature really ought to be added. It’s the last feature that’s needed for services like Komoot to actually become highly useful.

In State College, North Atherton Street is almost always too busy for cyclists; as such it’s generally avoided.

This has been discussed previously, but no official answer has arisen. It behooves OSM to come up with a fix to this problem.

What do you recommend with regard to adding this tag?

It is known all over the world that OpenStreetMap is a free source GEO based map service which gives access anyone to use its data for humanitarian work or something else, can be the key to implement a community .It is usually that now a days data is being one of the best object to make proper system, so why not in this platform.In the whole world all the community not getting all of digital advantage due to lack in communication system. OSM can be a communication system to communicate with them.

We who map in this platform and sometimes we do huge number of emergency map in any disaster or something else. It is the way to implement a community through mapping and I seem that in most of the map, all of community area not mapped with its valuable information which be helpful to local people or very little area has been under map.But we know remote area should be mapped to implement the community and OpenStreetMap is the one of the best source for implementing any of local community .

But you may hit a question that how is it possible ? Yes,it is possible cause there are lots of local mapper working here and contributing a lot.They are able to map on their own area remotely or field.By tracing from imagery we can find out all of important objectives like highways,buildings,water body, forest etc.

Highway and buildings are one of the most important element to map an area along with waters.

Happy Mapping..

December is election season in the OpenStreetMap Foundation. The Board is planning the next elections already, so now seems like a good time to talk about my first year as a member of the Board.

Why being involved in OSMF matters

OpenStreetMap is a project of many hands. All around the world, people are doing amazing stuff: mapping, building community, inventing new data uses, building tools. Yet most of the visible innovation is happening on the fringes, not the core of the project. That’s normal for a community like OpenStreetMap. For example, new mappers are much more likely to convince someone to start mapping then regular ones. If only because us hard-core mappers have been stalking our friends for ages already. You won’t be getting many new open source routing planning experts on board - they’ve already seen the light. It is the people who are “on the fringes of OSM” that have the best view of where we can grow further.

And yet, OpenStreetMap isn’t run by people from the fringes, but by core volunteers. While people all over the world are developing new “osm welcoming tools”, we haven’t even started talking about integrating such a tool into osm.org. While vector tiles are now the industry standard, we don’t even have a roadmap on how to get there. Time and again, we see people ringing alarm bells about the lack of progress in the core. I believe part of the reason why this is happening, is that from the inside out, all looks like it’s going swell.

Recently at the Portuguese OpenStreetMap Telegram group we have been discussing the issue of the Pokémon Go! Players that become OSM contributors with bad intentions, by adding fake parks or wrongly to their ingame interest.

We decided to check how many parks existed in Portugal by using overpass turbo back in August (kudos to Luis Forte for the help). To our surprise there was over 7000 parks. We decided to create a map roulette mission to validate the parks. Some are indeed hard to validate by arm chair mapping, some are not. Up til now we have validated 20% of the parks on OSM and acknowledged that more than 12 percent were indeed badly tagged and only 7% were correctly tagged.

As example,gardens of private property or grass in roundabouts. https://maproulette.org/challenge/9053/task/24888572
