Major Changes in Central Park Mall Jakarta

Posted by Reinhart Previano on 24 February 2018 in English (English)

Changeset details:

The Central Park Mall is one of the popular shopping malls in West Jakarta, Indonesia. It is also inspired by the design of the Central Park in New York City.

This mall has a park for visitors to walk around, called the Tribeca Park. Aside from that, this mall is also connected to the Tribeca (a 2-storey section of Central Park Mall consisting of several restaurants) and Neo Soho (the shopping mall below the new Soho apartment near to Central Park). These malls are owned by the same developer, PT. Agung Podomoro Land.

In this changeset I added the new Tribeca (mall) section at the other side of Tribeca Park, including the skybridge connecting Tribeca ↔️ Central Park ↔️ Neo Soho. I also added more details on Tribeca Park itself, including added new footpaths, restaurants, ponds, fountains and a new escalator. There's 1 more pond left unmapped, as I need to re-check on site for the accuracy of its position.

So far, here's the changes I made to this shopping mall. As of now, there might be some mistakes in my changes to, which I will fix it later.



And here's how my work is compared with Google Maps (as of 25 February 2018):

How should I tag a surf shop/cafe

Posted by ConsEbt on 24 February 2018 in English (English)

Hi everybody, I'm looking for suggestions to improve the tagging of the Surf House Dubai which I have [](added today).

Now I did add some tags to the surf shop as suggested by the wiki however I'd like to have some comments.

  • how should sale and renting of surf, wake and stand up paddling boards be tagged?
  • how to add the surf school?
  • how to add the surf shop - they sell board, parts, tee shirts, shorts, sunglasses, sunscreen etc.
  • how to add Yoga classes

What are your suggestions?

OpenStreetMap and Strava in Christchurch

Posted by Adam Heinz on 24 February 2018 in English (English)

Lots of global companies use OpenStreetMap. Take Strava, for example:

The Strava Global Heat map shows cycling activity around the world, including Christchurch. ( ).

The road lines are based on OpenStreetMap ( ).

By improving OpenStreetMap we can ensure that our fellow citizens are making decisions based on accurate information provided through 3rd-party providers.

An OSM Logo for Translation Projects

Posted by dcapillae on 23 February 2018 in English (English)

Some time ago, the OSM community in Spain had a discussion to add a country template and choose a new image for our wiki page on the OSM Wiki.

The OSM community in Spain has been using an OSM logo with the letters "ES". This logo was the same one that we were using in the WikiProject Spanish translation.

The Spanish-speaking OSM community in the world is not limited to Spain. Therefore, to avoid confusion between OSM Spain and OSM "in Spanish", we have changed the logo for this one, a simple and more generic logo which can be used in your OSM translation projects and wikiprojects.

Surau and parking in building enhancement suggestion

Posted by SNN95 on 23 February 2018 in English (English)

Whenever I want to edit this kind of religious POI, I found that only mosque option available. There are different for each of them. Mosque for big one and surau for small one.

I want to emphasize the surau. Surau is a small and can include in every buildings in malaysia. That's the rule for Malaysians or any investors that want to build one, they must include at least one surau.

So I want to edit to include surau in a building but there is none in the option or tag.

And other tag option like parking, ATMs, etc that can be include in a building. Maybe I can use the point but that not very convenient for a multilevel building.

This is just my rant for this subject. And if you think I missed the features option included in editor, feel free to tell me. Maybe I'm not explore them enough yet.

Why I need OpenStreetMap

Posted by SomeoneElse on 22 February 2018 in English (English)

(written in response to the discussions here and elsewhere, prompted by this blog post, which was in itself presumably prompted by this HN item)

Yesterday was a nice day, so I decided to walk from Derby to Alfreton (roughly here). The criteria were pretty simple:

  • No muddy paths
  • Only roads with footpaths alongside (sidewalks in OSM terms), or if necessary, grass verges (or very minor roads)
  • Somewhere to stop for something decent to drink and a bite to eat.

Ignoring "automatic routing" altogether, what map provider in the UK has that data? OSM does (at least in the area that I'm interested in). Google sort-of does - I'm sticking to roads here, and via their StreetView I can see that e.g. Codnor Denby Lane does have somewhere to safely walk, but it's not really practical to "virtually walk" an entire route in Google's StreetView to check it before setting off. HERE has some aerial imagery but not with enough detail. The UK's Ordnance Survey surely has most of the data, but getting at it is hard (even if you pay them money). The small map on this page can be zoomed in to hint at sidewalk info, but neither the buyable OS Explorer map (which I have a copy of) nor this page which I presume is based on OS OpenData, do. Bing can show basic road info and their own or OS Explorer's map style, but no "is this walkable" information.

With regard to POI data, Google was (until yesterday) the only one that had the correct name for this pub, and does link through to food and beer details (even CAMRA, usually the go-to guide for this sort of thing, are out of date). However, there's no differentiation on the map beyond a "place that serves food" icon and a mousover blurb ("family friendly chain pub and restaurant").

So am I missing something - is there anyone out there with this level of data that's available in an accessible format, other than OSM?

How are you "supposed" to map landuse?

Posted by Nikola Bura on 22 February 2018 in English (English)

I know exists, but I've got a separate question...

Basically, is it intended for landuse to eventually cover the whole entire globe, so that every available spot of land is marked as either residential, commercial, parkland, or water, etc? Or should landuse only cover a few areas, while the vast majority of the map is left as "standard" empty grey?

The European countries seem to have a lot more landuse cover than the US, so should I use them as an example?

The "residential" landuse is what's confusing me here, in particular, because I could mark vast swaths of the map (think apartment blocks, suburban neighborhoods) as "residential", or I could leave them unmarked. Same goes for things like "forest" and "farmland"... should all woods and fields be marked with landuse, or just left empty? Not sure what the usual approach is.

Addresses in southern Platte County, Missouri

Posted by farallon on 19 February 2018 in English (English)

As inspired by Angela Morley's post on the 15th of February, I will be attempting to systematically fill in as many addresses as I can in areas of southern Platte County, MO, including areas such as Parkville, Riverside, and so on. I'll be starting with residential, in the areas south of MO-45, and working outward from there as I can. Wish me luck!

How to map buildings within a building?

Posted by howdystranger on 19 February 2018 in English (English)

Hi all,

Hoping for some guidance.

Here's the area I'm looking at.

It's a hospital in my city. It's a series of buildings which are connected together. What is the best way to label the individual buildings? Previously a mapper had put individual buildings on top of the underlying buildings but that doesn't seem great.

Many thanks

When the World Needs a Map, Give them a Database

Posted by jremillard on 19 February 2018 in English (English)

This was posted this week.

I think it is fair to say that it has upset people, myself included. OSM seems like it is doing fine. contributers are up, the servers are running well, ID is amazing, the state of the maps are cranking along, OSM is widely used, perhaps even essential, everything is all roses, full steam ahead....

When the World Needs a Map, Give them a Database

Ouch, that one hurts.

Then at the bottom ...

The OpenStreetMap Foundation Culture

Ouch again.

We need to think about our relationship with our commercial/non profit partner organizations. At a high level, we need each other and strong relationships should be a priority. However, inevitably there are situations where they are in conflict. For example, OSM's refusal to offer paid services to support its considerable infrastructure needs seems like a clearcut example of our partner organizations wanting to OSM to keep off of their turf, weak, and dependent on them and their donations. Please, don't blame Mapbox, this isn't Mapbox's fault, they are doing a great job, and I am delighted that they are so successful. But, it is hard for me to understand how MapBox can raise 164 million USD last year and the OSMF doesn't have enough money for any full time system administrators or software engineers. The US OSM chapter, is in the same boat. They are going to be hiring a director next year (yes!!), but the plan is to have the role focused on SOTM, outreach, mapping parties, blogging, twitter, and other safe/non-core activities (bad!!).

If you care about this, please join the OSMF and vote. Also, the US OSM chapter is voting now.

JB Brown - photomapper

Posted by NunoCaldeira on 18 February 2018 in English (English)

Im posting this trying to support someone that contributed a lot to OSM via his street level imagery, either being on Mapillary or OpenStreetCam for others to map on OSM. If you could donate, to help him repair his vehicle to get back on photo mapping, go to his GoFundMe page

JB Brown rig for capturing street level imagery

Heres the story:

My name is JB Brown. Online I am often known as JBTHEMILKER. I have become something of a legend in the digital mapping world. In just over a year of contributing to Mapillary I became their top worldwide contributor with 8.3 million images and 146 million meters mapped. Mapillary account

I'm also #2 (I was #1 For a while) on the Openstreetcam app I've contributed 1.2 million images in less than 4 months and mapped 22,400 miles for them. All this has been done at my own expense.

I'm a retired, disabled firefighter. For the last 5 years I've been serving the Amish of Ohio by hauling families when their trips were longer than they can go with a horse and buggy. My van had nearly 400,000 miles on it. Recently the repairs out did what I was bringing in. Then in Wisconsin the transmission went. I ended up giving what was left of my beloved van to the firm who towed it up in Wisconsin. The other side of who I have become is the mapping photography I've been doing. Back when Google Earth was accepting pictures I was among the top contributors in this country. When Google pulled the plug on Earth I started contributing to Mapillary and later to Open Street Cam, both are firms that are working to gather digital data to improve our digital maps. I am the top contributor worldwide on botth these sites or I was until my van broke down on Christmas eve. I'm asking for contributions now, just as I have given freely in order that I might continue to serve those who have come to depend on me, those who I enjoy serving.

OSM and Gender - Invitation to Online Discussion

Posted by Heather Leson on 18 February 2018 in English (English)

How can we improve the gender balance in participation and in map content? There are some amazing leaders and best practices across the global OSM community.

Before the holidays, we had a vibrant conversation on the OMSF mailing list about gender in OSM. Some great examples of inclusive participation include GeoChicas, YouthMappers, and Humanitarian OpenStreetMap Team. It would be great to hear from women and other genders that are often rare voices. With such a large community, we know that there are more people doing great activities to improve engagement.

Kate Chapman and I would like to invite OSM to join us for an online discussion about OSM and Gender. Given that women and other genders are a often a smaller group in OSM, we ask that this conversation start with us. Then, we will be sure to include the wider community.

Some of the potential topics could be: opportunities and challenges to be more inclusive, program ideas to support diversity in OSM. We will define the agenda and next steps in the call. Then, we will report back via OSM diary entries.

Here is a Doodle to be filled out by Thursday, February 22nd at 1700 CET.

Once we collect the best times, I will announce by Friday Feb. 23rd. The first meeting will be held in the Europe, Africa and Americas Time zone.


The second meeting will be hosted in a timezone friendly for Asia (morning) and Western North/South America. (evening) The call will be hosted on mumble

The OSMF community cited some resources which reflect participation inquiries. Other resources are most welcome. Just add them into the comments.

Thanks and looking forward,

Latest Changes

Posted by tyr_asd on 18 February 2018 in English (English)

Want to get an idea about what contributions are happening in OSM in your region? Maybe you're even looking for a way to better review map changes (hint, hint)? A good starting point is probably my latest-edits page tool. It displays all objects that have been modified during the last week alongside with their respective changesets.

One major drawbacks of the tool was that until recently, deleted map objects (and changesets consisting solely of deletions) were not displayed on the page. Now, deleted objects are displayed as faint "ghostly" outlines on the map. In the same way, you can now also see how modified objects looked like before the respective contributions happened. This can result in a nice looking "shadow" effect when for example buildings have been realigned to better aerial imagery.

Also, you can now select between the latest changes from the last day, week, or month, and directly zoom to the location of a particular changeset:


The tool still doesn't show intermediate states of objects that have been modified more than once in the selected time period, as well as modifications to relation objects.

Programmatically, this new version is implemented by using an Overpass augmented diff query (switching over from a "regular" OverpassQL query using the newer statement) and some massaging of the returned data to get them properly in shape (it sorts the data into two buckets – one for the state of the data before the respective edits and one for the current state – then uses osmtogeojson to generate GeoJSON which can be put on the map).

Maping Ayrton Senna's Farm / Mapeando a Fazenda de Ayrton Senna

Posted by Junior Intervales on 17 February 2018 in English (English)

English: Ayrton Senna da Silva was a Brazilian racing driver (21 March 1960 – 1 May 1994) who won three Formula One world championships for McLaren in 1988, 1990 and 1991, and is widely regarded as one of the greatest Formula One drivers of all time.

Senna used to spend his free time at "Fazenda 2 Lagos" (2 Lakes Farm) in Tatuí - SP, where he built a private karting track, the farm now is run by his parents and brothers since his death in an accident while leading the 1994 San Marino Grand Prix for Williams.

Mapping North Andover, MA

Posted by Angela Morley on 15 February 2018 in English (English)

I'm a firm believer that maps are more useful with the more data on them as you can put in. Seems logical, right? When I was looking at OSM, and OsmAnd, it appears that the local functionality of the system as far as address and route guidance is completely useless as of right now, primarily because nothing has addresses entered. It's great that so much roadway and outlines of buildings have been added, but the map is pretty much useless for the end user who just wants to get from point A to point B.

For this reason, I did some digging and was able to find North Andover's zoning map, which includes property address numbers! (

I've set out to iterate through all of the addresses I can systematically over time and transfer them all into OSM. I'm sure there's easier ways... some suggested JOSM with a MassGIS address layer, but JOSM is fairly difficult software to use and I don't quite understand it yet. So far, I've been using iD editor, but that has challenges in that anything over about 100 concurrent edits in the current changeset starts really bogging down the web browser, so I have to save often.

The mission: to update all addresses systematically from west to east, to draw in driveways, and to fix misaligned buildings as I go through.

This is going to take some time.

How to track and encourage contribution?

Posted by bdiscoe on 15 February 2018 in English (English)

As I've been mapping heavily since 2013, I've tried various ways to track my progress. It's really great to feel that your mapping is making a visual and statistical difference! However, as of today, there is no good metric, and it's very frustrating. Understandably, there is no way at all to measure actual quality or value of contribution across users, because it's subjective, and users are very different from each other. However, for me, I know that I map at a consistent quality and node density, so I should at least be able to measure my progress with respect to myself! Here are things I've tried:

  1. Looking at my Heat Map. At first I thought, this is great! A clear visual indication of how much of the world I've contributed to, and a clear goal to cover the world! But, by 2014, I observed many edits weren't counted, confirmed in an email exchange with it's author, Pascal. To its credit, YOSMHM's goal is only to give a rough idea of where a user has edited, and it does that very well. However, once you've edited for a while, you can add a thousand nodes and see nothing on the map change. That's just frustrating.

  2. Looking at the "last modified" nodes and way on HDYC. This was great, I could do a busy night of editing and the next day, HDYC would show my "last modified" nodes went up by, for example, 10K nodes. It gave a good indication of how much I was contributing. Sadly, Pascal changed the website around November 2017 so it no longer shows "last modified". That's frustrating.

  3. Refreshing the map after doing major edits. This used to be possible by right-clicking the main map's tile and submitting it to the "dirty queue", so it would be re-rendered and you can see all your work. This gave quick visual feedback and confirmation and an encouraging sense of accomplishment! Sadly, changed how their map works (some blame OpenLayers?) so now you can't get tile URLs and can't request re-rendering, just wait for several days or more for the server to eventually re-render. That's very sad.

  4. Looking at the #MissingMaps leaderboard you could see your "Total Edits", "Buildings", "Km of Road" numbers, and watch them go up in nearly real time! It used to be a little flaky (ignoring the occasional changeset, which was frustrating), but since December 2017, it now fails to count most changesets. I can submit, for example, 10 #MissingMaps changesets in a day and only see 1 of them counted, the rest ignored. That's beyond frustrating.

In regards to #2 (HDYC), I did write a small C++ program (on my bitbucket) using Osmium to read the OSM Planet file and count the last-modified for each user. But, this is awkward, for several reasons:

  1. The planet file is huge (39 GB!), and I have yet to automate, so it's a long slow manual download.

  2. The planet file is only updated once a week now. I have no idea how HDYC updates every day!

  3. I haven't written the code yet to format the results into a nice, sortable web layout, or to integrate it with my existing spreadsheet of user notes.

So, that's the state of things. All the ways that used to exist, to get visual or numerical feedback or progress metrics, are gone. In my opinion, it's not just a personal frustration, but a lost opportunity for OSM as a movement, that we are missing this simple way for mappers to get encouragement and acknowledgement.
