OpenStreetMap
I recently published a blog article which serves as a “mega-tutorial” for getting starting an analysis project with OSM data using PostgreSQL and Python.
Check out the full article here: https://travishathaway.com/posts/2022-04-02-processing-osm-data-with-postgresql-and-python/
It was quite exciting to meet virtually with the new team lead of OyoMappersTeam ,one of the founding team of Unique Mappers OSM Community Nigeria , The team was co-doundaed by Mrs Mary Marcellineus and Victor N.Sunday in 2017. The Team Coordinator, Mrs Mary was also excited to have us discuss ways of breaking barriers to community engagement at Oyo. One of the constraints she is battling is the access to internet connectivity for mapping which is very costly for members to afford . Most often she had to use part of her meager salary ,to ensure, a mapping event or training is hosted . In response, the team was given hope ,that ,such barriers is bound to be overcome as we all work together as a local community NGO for Nigeria -The Unique Mappers ,so we can seek for funding for humanitarian response mapping in Nigeria. If members were up and doing with annual dues/reg ,that would serve effectively to provide internet subscription support for the team but now we can only rely on possible micro grant and donations ,to help us provide sustaining fee internet subscription for mapathon. The team was advised at the moment to get Mi-fire for monthly subscription to hotspot for 32/64 participants or make use of their smartphones. While,Unique Mappers would always be there for the team to provide necessary support. The meeting was as an exciting way to wrap up the day’s activities for OSM volunteering
Russia treacherously attacked Ukraine on 24 February 2022, striking with missiles and bombs at airports, military bases and civilian infrastructure. This was another escalation of hostilities that began in 2014 with the annexation of Crimea and the partial occupation of Donetsk and Luhansk Regions.
On behalf of the OSM Ukraine in connection with Russia’s ongoing military invasion of Ukraine we are turning to people who are contributing to the development and improvement of the OSM data.
The Russo-Ukrainian War is unfolding on many fronts including the information one. The possible use of open data by Russian invaders to plan attacks on military and civilian objects is one of the most important reasons why we ask you not to perform any mapping of objects in Ukraine.
We shall take action to amend (delete, modify, revert to the previous state etc.) any found cases of mapping related to military or critical social infrastructure facilities as well as contact the DWG and other OSMF working groups to ban the users who systematically make similar changes (more than one).
Such a request (demand) echoes the provisions of the Article 114-2 of the Criminal Code of Ukraine according to which “Dissemination of information on redeployment, movement or location of the Armed Forces of Ukraine or other military formations established in accordance with the laws of Ukraine, if it is possible to identify them on the ground, if such information is not published by the General Staff of the Armed Forces of Ukraine, committed under martial law or state of emergency, shall be punishable by imprisonment for a term of five to eight years” (https://zakon.rada.gov.ua/laws/show/2160-20#n10).
Oyomappersteam executives had an interaction with Uniquemappers team executives on the training they had with Mercy, the Regional Ambassador.
In March 2022, On the International Women’s Day, I presented a talk “Open Mapping Tech for women in Climate Crisis” which gave an insight into what it takes for wonen to participate in mapping by leveraging on some of these applications so that their voices can be heard by the larger society/world. I was able to interact with some women from other countries. The program was anchor by Uniquemappers network Nigeria.
If you want to import OpenStreetMap data to PostgreSQL (+ PostGIS) database two popular tools are osm2pgsql and imposm3.
Both were designed to prepare data for rendering although some time ago osm2pgsql was upgraded with scripting capabilities that go beyond simple mapping files that specify what tables to create and what objects should be inserted there (filter by tags).
There is also osmosis if you want a - more or less - copy of OpenStreetMap database.
imposm3 development was put on hold due to lack of funding while osm2pgsql is actively developed. This makes it questionable choice to use imposm3 but it does have some nice qualities that can make it better for some projects.
In my opinion it’s a very good tool that is useful when:

Carrying on with my Brooklyn survey… In the Bushwick neighborhood, I’ve found another new building to map, and a good opportunity to show a little more of NYC’s Building Information Search tool (aka BIS.). Like last time, we’ll start by finding the building’s BIN and height using BIS’s search option 1, with borough Brooklyn, housenumber 618, and street Bushwick Avenue. Here’s the resulting Property Profile Overview page:
(That exciting red bar means this development is currently in trouble with the Dept of Buildings, but that’s none of my business.) We find the BIN, 3425505. Note the “ALSO SEE OTHER BIN(S) BELOW” message and the “Additional BINs for Building” field – these are older obsolete BINs that this new building has supplanted. The “DOB Building Remarks” note about multiple lots being merged tells the same story, which is a very familiar one in Brooklyn: A large new building has replaced several smaller buildings.
Hi all,
MapComplete has been (partially) translated in 21 languages by now - an amazing feat that I could never have done alone (for starters, I don’t speak 21 languages).
(For those that don’t know MapComplete - it is an easy-to-use map viewer and map editor. It shows POI on the map and when clicking something, shows the known information and asks questions about it)
Translating MapComplete started by manually editing the translation files, making a pull request, … A next step was moving over to Weblate, where there is more support for translations.
However, one has to know where to find this translations and translating can be tricky, figuring out which piece of text goes where.
That is why I launched a new feature today: toggling ‘translators mode’ (in the copyright tab) will add little buttons, taking you directly to the page to translate the string (or to fix some typos):
So: please help to translate MapComplete in your favourite language!
Some remarks:
I am really glad Cad-Man are rendering- WC still seems to have a problem. I did have it as administrative boundary for a bit with the admin_level tag, but I think the admin_level tag was throwing me off- that tag seems to be specific in the US for certain values (=6), regions(=5), etc. Scrubbing the admin_level tag seems to help.
There are still a few national forests kicking around with the boundary=national_park tag to clean up, and there are probably national parks mapped as such that have private inholdings within them not depicted- only the outer boundary is mapped. Case in point, though not a national park, is Adirondack Park- osm.org/relation/1695394. Adirondack Park is a stretch since there is no national designation for that, unlike National Forests and National Parks. I agree the green line render is a bit much if we used the boundary=national_park tag, and the consensus from the mailing lists seems to be a strict literal interpretation of national “park”, if anything to keep people getting confused- best to stay conservative with the interpretation.
I also made some progress on the Mackinaw State Forest - Gaylord Unit late yesterday and should be done with that one. Then back to fix up the Lake Superior State Forest units. The fix for Tahquamenon Falls State Park seems to be rendering when zoomed in. The Newberry Unit is rendering also- osm.org/relation/13993909. Shingleton and Sault Ste. Marie still seem to have problems. I would have liked to move on to the Pere Marquette but a little detour to the UP was a nice change.
When I was a kid, my dad relied on an over-sized atlas depicting roads, towns, public lands, lakes and streams at the county level. He used this on road-trips, consulting it while exploring to determine if uncertain just which way to go. Signs were important- the signs marking the corners of state game areas. Road signs. County boundary signs. They were a navigational aid. When I got old enough, he gave me my own atlas. By that time however, the internet provided a bevy of informational maps at much smaller scale- letter-size maps showing individual public lands, trail maps, and much more. Updated and more accurate than the old atlas often based on commercial data sources and the 24,000-scale series of USGS topographic quadrangle maps. Today, we can make our own paper maps using online mapping applications, consult a digital map on a cellular-connected smartphone pocket computer or wristband computer, create our own spatial data using high-accuracy GNSS or heads-up digitizing from remotely sensed products, or even contribute to the public world-wide map of OpenStreetMap. There are so many options in this new digital environment to explore and find uses for. It’s wonderful today when we still have our over-sized paper atlas or folded maps available at any outdoors store, but also so many more options to access, create, and share maps. So whether you have a paper map in your pocket, or a mobile remote connection to the world-wide digital map, or a window onto the world from your home computer, I hope you find great experiences exploring and learning more about the world.
I have no answer as to whether it is useful. Now I am not talking about real benefits, but about intentions
They did nothing useful for Ukraine map before. They do not worry, about OSM data, even if they talk about it. They want the Russian army to do the same to us as in Bucha. They are passive supporters of Putin. I think that such guys have no place in OSM

The ways representing the Manistee and Cadillac ranger districts now are split out into separate relations. For the Manistee National Forest super-relation, I added a way to represent the administrative Forest boundary, snapped to the adjacent outer edges of the ownership ways. This gives some geometry for the relation when you search for and pull it up. To avoid confusion over actual ownership/extent of protected_area / leisure=nature_preserve, I scrubbed those from the Manistee relation and they are only on the district subarea relations. Manistee is tagged boundary=administrative, the subareas tagged boundary=protected_area. We will see how the tagging savants respond to this strategy. I did add an admin_level=6, the equivalent of the county level, to help show the Manistee admin boundary at a wide zoom level. Maybe it will work. I thought about adding a government=forestry tag as well to show that it’s not a civil\municipal admin boundary, but didn’t add it:
Splitting Cadillac and Manistee resulted in some simpler geometry. Previously the ownership extent protruded out into Hodenpyl dam pond, so I brought that back to the shoreline (snapped to edge of natural=water). Still need to add an admin_centre node for the Cad-Man office in Manistee and the Forest HQ in Cadillac.
In other news I added in the 5000-acre Dunbar experimental forest in the eastern UP, it’s a MSU property, I tagged it with the university as the operator and leisure=nature_reserve. I saw a Notre Dame school Forest somewhere in the W UP already in OSM and I know UofM and MTU have school forests too. And there are county forests too- Marquette has a big one near the old Air Force base. I Still need to get back in and finish up the Mackinac State Forest, Lake Superior State Forest, start on the Pere Marquette. And sometime or another see what’s wrong with the Ottawa NF. Gotta fill in the northern lower and UP!

Обращение к сообществу OSM и к его участникам!
Россия вероломно напала на Украину 24 февраля 2022 года, нанося ракетно-бомбовые удары по аэропортам, воинским частям и объектам гражданской инфраструктуры. Это явилось очередной эскалацией военных действий, начавшихся в 2014 году с момента захвата Крыма и частичной оккупации Донецкой и Луганской областей.
Мы, сообщество OSM Украина, в связи с продолжающимся военным вторжением России на территорию Украины обращаемся к людям, которые вносят свой вклад в развитие и улучшение данных OSM.
Мы призываем всех воздержаться от какого-либо маппинга на территории Украины в данный момент!
Российско-украинская война идет на многих фронтах, в том числе и на информационном. Возможное использование российскими захватчиками открытых данных для планирования атак на военные и гражданские объекты является одной из важнейших причин, по которой мы просим не предпринимать каких-либо действий по маппингу объектов на территории Украины.
В случае обнаружения случаев маппинга, касающегося военных объектов или объектов критической социальной инфраструктуры, мы будем их корректировать (удалять, видоизменять, откатывать к предыдущему состоянию и т.д.), а также обращаться в DWG и в другие рабочие группы OSMF для блокирования участников, которые систематически вносят подобные изменения (больше одного).
Такая просьба (требование) перекликается с положениями статьи 114-2 Криминального кодекса Украины, согласно которой “Распространение информации о перемещении, движении или расположении Вооруженных Сил Украины или других образованных в соответствии с законами Украины военных формирований, при возможности их идентификации на местности, если такая информация не размещалась в открытом доступе Генеральным штабом Вооруженных Сил Украины, совершенное в условиях военного или чрезвычайного положения, наказывается лишением свободы на срок от пяти до восьми лет” (https://zakon.rada.gov.ua/laws/show/2160-20#n10).

The OyomappersTeam together with the GIS students organised an event.
I love mapping botanical gardens. So when State of the Map US wrapped up last weekend, I was excited to make a return trip to Tucson Botanical Gardens for some serious micromapping. I had already spent hours adding buildings, garden spaces, and trails. Now I could work on benches, fountains, artwork, etc. Here’s how it looks after a few more hours of micromapping:
.
The garden currently has an augmented reality exhibition called Seeing the Invisible. Users download an app, and it overlays 3D images of artwork over the plants you view through your phone. Any time I use an app like this, my first question is “What map are they using for navigation?” In this case it was very unclear because there was no attribution on the map or on the Credits page. You can view the map here.
I have put the following item on the Irish mailing list. I will put it here to widen out the inputs. If you have some time, and some experience of adding this landuse. Rather than repeat all my concerns I will simply post visual some examples of the issues I am talking about here.
Example of an urban landuse=residential which is gigantic.
Example of a landuse=residential interpreted at running along a roadway to incorporate ribbon(roadside) developments. This landuse connects a huge number of disconnected places.
Example of a landuse=residential residential where the landuse is trimmed back from the public highway and walkway, and doesn’t extend beyond the collective block of properties.
Over the last few weeks I have been looking at 3D rendering of OpenStreetMap data. Much of the focus has been on the old town of Dunkeld in Perthshire, Scotland.
I learn iteratively combining trial and error with reading documentation. Different rendering options like demo-f4map.com and Kendriz3D plugin in JOSM provide my informational feedback loop. The former is easier to use but the Kendriz3D plugin is quicker to see the updates I make.
I went house number surveying with StreetComplete yesterday in Callan, Co. Kilkenny. They have some very strange house numbering there, I can tell you.
One case, where whoever screwed the numbers on the door got them mixed up, so the sequence goes 34, 35, 63, 37 etc. But that’s what’s on the door, so that’s how I mapped it.
Another case, where the sequence is out of order, but presumably, because the houses got their number in the order they were built in.
Then I continued along Mill Street into what would eventually become Collins Park with a sign of the name in English and Irish in a wall (mapillary), so at least, I had some idea of the street name. However, the numbering continued from Mill Street (with ridiculously high numbers for Ireland, if I may add). I decided to ask the resident of no. 462 what street he lived on, and his answer was “The sat nav says Collins Park.” Very likely (everybody I know who isn’t a mapper uses it), that means GoogleMaps. So, what street do I put under addr:street? Do I follow the logic of the sequencing and give his house addr:street=Mill Street, yet adding “Collins Park” as the name to highway=street or do I follow the local’s information which in this case is very, very likely taken from Google? And which could easily lead to duplicate numbers for the same street?
I’ve done it the other way around for now, but I’m not happy with it.
A similar problem occurred elsewhere, where the name of the street “Green Lane” presumably continues from where I saw the only sign (sorry, no photograph, but it’s the street that led/ leads to the Fair Green), but the sequence on one side of the road continues from Mill Street, but across the road, one of the houses had “2 Kingscourt” (mark the different spelling from the actual street name - Kings Court - , FFS, isn’t anything easy in Callan?!). After my tagging, the houses on either side belong to different streets which they are not physically on.
