Recently, I saw a diary post about Microsoft releasing US building footprints, and I wondered how they could be used to add buildings to OSM in my favorite editor. I quickly found out that large files won’t load in iD. I searched for a tool that could make the files smaller and usable and found one called geojsplit.

I took it upon myself to examine the code of that project, to learn a bit of JavaScript, and to form it into a tool more suited to my needs. Large database files won’t load in iD, but they can be made smaller in size by omitting features outside the viewing window of the editor. As a result, I can now see the building traces in my favorite editor. :)

Re: Changeset: 61902366 180822 1414 edit Alberni Sproat Lake Taylor Woodlands - 0 errors 2274

I posted this changeset to correct problems with polygons arising out of new OSM rendering procedures - the most significant edit being to split a large polygon into two or more smaller polygons. I have created a new polygon, which JOSM tells me has no errors, although errors still exist in the remaining old plygon which still need to be corrected.

As this changeset hasn’t been posted yet, I can’t proceed with further edits required as a result of changes in OSM procedure.

Hello,

A few months ago I switched to the contact: tagging scheme for contact data. In this tagging scheme “contact:” is attached to the beginning of the tag. It is the newer version of the “normal” tagging. osm.wiki/Key:contact

In my opinion this is much more accurate and clear. On the one hand it is clear that this is contact data, on the other hand a much more precise specification is possible.

For example, many POIs have social-media pages that can not be meaningfully entered without this tagging scheme. Without this scheme, a new tag has to be created for every new social network, which could be shown by many clients only years later, if at all. With this scheme you can add any network or similar and every client knows immediately what it is.

This scheme is currently used at about 10%, but is not yet set by any editor as a standard (as far as I know).

In my opinion, it is time to switch to this tagging scheme. What do you think and did you knew this tagging before?

Best regards, Chris

This entry is a copy of my comment in a discussion on some of the OSM Carto rendering ideas. It’s so general, that I think it makes sense to show it for more people. I have some more thoughts on this subject and I hope I will write them down too.

I believe the main obstacle for better coexistence of big cities and outdoor rendering is #1957 “equalizing” ticket being unresolved.

I think about “WMAs” (well-mapped areas), which are located in the big cities where mappers were active, that they make the biggest difference. They start to be very rich, because this is the reality, which was not well covered by mappers just a few years ago. We could rely on this incompleteness up to some point and render whatever was available without critically rethinking the whole system for years. But this is no longer true and the WMAs begin to be drastically more dense than outdoor areas. This is nobody’s fault, it’s just the unexpected consequence of the success of OSM in gathering all kind of data. Of course, we might stay with what we were showing before, but it’s just closing eyes to avoid noticing the constant change of OSM data. Something like taking the snapshot of some past moment and refusing to take more current ones, just because it’s more familiar for cartographers than trying to face these new challenges.

I like the outdoor rendering and when it doesn’t hurt, I’m happy to make it also rich. There are places where we outperform typical (if not all) outdoor maps with details, like for example here:

Some Brouter profiles even contain a switch to just ignore bicycle=no tags because of massive incorrect tagging.

Mandatory cycle way (G11 or G12a) is not equal to forbidden for bicycles (bicycle=no)

Stood about fifteen minutes on the roadside yesterday, trying to decide what to map. On one hand, it was my weekly bus survey day, and on the other, I wanted to see for myself whether the reportedly-newly-opened Pink Line of the Delhi Metro really was extended till Lajpat Nagar or not. Well - Bus Day won over, so I took a 448 to Punjabi Bagh. On the way, on a bridge, I saw a train arrive at a platform on the Pink Line. Fancy-ass new coaches, and the sign declaring “Lajpat Nagar”. Killed two birds with one stone 🙂 [1]

Upon reaching Punjabi Bagh, I saw that a road there was called ‘Shiv Das Puri Road’ on a sign, and ‘Patel Road’ on the map. Figured I had best confirm the name with the locals, in case an alt_name or old_name was required. There was a tobacconist and a food stall there, but going up to them and asking, ‘Say, what’s this road called?’ would sound a little silly, given that there was a perfectly serviceable sign with the name there.

Solution - “Say, can you tell me where’s Patel Road?” Nobody had a clue 😄

I’d not even mapped all the stops at the place when it started raining. Why does it always have to start raining when I’m out surveying a bus route? 🤔 And this time, rain of the sort where it’s largely immaterial whether or not you have an umbrella - I merely walked, umbrella in hand, from a bus stop I was mapping to the one where I’d get the other 448, a distance no greater than 500m, and by that time the only part of me that wasn’t drenched was my bag with the precious phone in it.

today was splendid!!!!!!! an entirely unique encounter…..i got to spot areas and map…mapping the buildings was interesting….cannot wait for tomorrow!!!!!!

on my first day of mapping as a unlque mapper, i was able to map some buildings in portharcourt al;ng igwuruta, choba areas and i also mapped some buildings in japanthrough this website> www.osm.org

Am happy being a part of this team,i cant believe i can really do this. I have trained two persons whose usernames are princess70 and blessedaurika and also was able to map 291 buildings in Onitsha Nigeria today. #UniqueMappersTeam# LetTheGirlsMap# Hurrah!!!

I’m Cesar Alfaro from a remote place in the Peruvian Andes, 3 years ago I started interacting with OpenStreetMap, and as it had to be, my first OpenStreetMap edits I did in the place where I was born, then I was part of the data team of Mapbox and Develment Seed respectively, where I officially started adding large-scale, high-quality data to OpenStreetMap all over the world, you can take a look at my HDYC profile. Below I am going to mention an overview of the most important mapping projects I have worked on.

Humanitarian mapping projects

I’m an active collaborator of HOT mapping and validating efforts. Below the list of projects I have collaborated.

I just heard from two persons i told about Youthmappers that they have successfully signed up and am so happy… Have jux got to follow them up and ensure they start mapping..More are still learning about it ..#Youthmappers #Letgirlsmap#Uniquemappers

while studying for mine exams, i over heard someone saying she had just mapped the whole of Akure in Ondo State and was full of amazement, thinking how that could be possible. Got to talk to someone by name Ijeoma66 who is a member of the team and she explained what it was all about…. i got interested and joined, and was able to map 4 buildings in choba. it still unbelieverable, still finding it hard to believe its real but actually, it true and amazing. Hurray let the girls map.

I’m in the process of changing map.atownsend.org.uk so that zoom level 13 can still be used as a “route planning” layer but walls, hedges and ditches don’t get in the way. This wasn’t originally a problem, but people have since mapped lots of fences, hedges,walls and ditches, and it can be difficult to see footpaths at that zoom level now. Here’s a screen showing half new tiles, half old ones:

That corresponds to here on the site and here in OSM. The new version will probably be rolled out in a week or so’s time. Other zoom levels will be unchanged - you’ll still see hedges and ditches a couple of zoom levels earlier than with OSM’s “standard” style, and paths will still be legible 2 or 3 zoom levels earlier.

Data visualisation meets children’s curiosity. I immersed myself in geoinformatics to find out how postal services in the USA, in Germany and in Hungary carved their countries into mosaics of postal code areas. Visually striking maps emerge from the opaque depths of numerical data. Do enjoy and please share.

OpenStreetMap provided me with the data for Germany and Hungary. What a resource! I learnt a lot about querying the database. Many thanks to the designers, programmers, contributors!

It was an amazing experience.. Talked about mapswipe and also shared the mapswipe app to interested persons.. It was fun #Youthmappers#Letgirlsmap#Uniquemappers#Microgrant2018#Mapthedifference..

This is a followup to my previous question, for which I did receive responses, to help me to develop a better understanding of OpenStreetMap.

I want to post a screenshot saved as a jpeg image to a new diary entry, and attach an explanation of the problem illustrated in the screenshot. Is there any way to do this that doesn’t require posting to a third party application, then posting a link in the diary entry to the third party application?

I don’t have any third party applications that I can post the jpeg mage to, save Facebook. If I use Facebook, the link allows people to see other parts of my site; which isn’t acceptable.

I have a question to pose to the OSM contributors body regarding rendering of natural=wood areas, which I think would be better described with a screenshot of the rendered map.

I realize that OSM is powered by volunteer labour, and I highly appreciate it, I’d just like to find out how to get an answer to my question.

Specifically, some of the areas that I have tagged in the Alberni Valley as natural=wood, show up as dark green on the rendered map; whereas other, adjacent areas, with exactly the same tagging, do not show up as dark green but are essentially blank, nor do the labels attached the unrendered areas appear. If I could post a screen shot, this anomaly would be a lot easier to understand.

This problem has just recently appeared, and through no action of mine, as far as I know. I refer to the rendered map frequently, to view how my edits (using JOSM), appear.

Will this work: link to Facebook document?

Wow! the experience our trainees got from us day before yesterday was awesome. The training was coordinated by our well experienced and a professional Mr Sunday Victor who is currently a Cordinator of UNIQUEMAPPERSTEAM, Nigeria. Trainees were trained on how to select a task and carry out mapping of a disaster areas using Task.HOTOSM. The trainees equally learnt some basis of GIS and Remote Sensing during the training which make them even became more excited as the training became a fascinating one. I took the advantage of the training and mapped out some areas prone to disaster and other environmental hazard in Nigeria and my heart was full of joy. Therefore I humbly thank the openstreetmap founder for creating a platform that has become a major tool for geospatial data generation which helps in responding to disaster and Lessing the impacts of it across the world.

Well, on my first day as an editor, I made some mistakes.

It’s right there on the wiki, very clearly: Imagery can be wrong. But I didn’t though of that when trying to fix this lot of roads which seemed oddly aligned with Bing imagery. I’m sorry.

I think there should be more advice about that on at least ID’s walkthrough (a link like the above one maybe). I had no idea that the map could be disaligned with the aerial image.

There’s some way to revert a changeset?
