If you are a user of OsmAnd Maps for iOS, you might have to refrain from using the current version (3.14) to edit OSM POIs. I just figured out that, after editing a bunch of POI opening hours in my suburb, the changeset also affected the locations of the POIs, even though I did not touch that.

It looks like the editor rounds the coordinates of the POIs to 6 significant figures, which might look like a move of only a few meters on the map, but the changes get more drastic as you move away from the equator and the meridian. I suspect people editing in Oceania and East Asia will see more obvious changes.

In this picture, from data in eastern so-called Australia, the arrowheads roughly show where the POIs should be, and the green line shows the longitude where they were moved:

Apartment complex addresses

Posted by stragu on 30 October 2016 in English.

Recently, I have mostly been adding house addresses around my neighbourhood.

current focus on local addresses

One issue I am running into is that I can’t figure out the best way to set the address for an apartment complex.

I am currently trying to tag individual buildings with building=apartments, and an area that encloses all the buildings with the address tags (like addr:housenumber, addr:housename, addr:street).

My first OSM meeting

Posted by stragu on 16 December 2013 in English.

I organised yesterday my first OSM meeting, at the Brisbane Square Library of Queensland. Because of a lack of advertisement and the difficulty to access the library after hours, I ended up giving my presentation to a crowd of two attendees: my wife and a good friend. It was ok because it was my first try and it was a good way to give my presentation a go and get some feedback. My very good “students” got to do a tiny survey of the Brisbane Square and add a few POIs together, and this brings two new users to OSM! We’ll see if they end up coming back to contribute to the project a bit more ;)

Here is my presentation, for anyone curious or needing ideas for their own. Feedback would be very welcome!

Hopefully I can organise more meetings / mapping parties around Brisbane; I got a few responses from contributors who would have loved to join but could not make it, which is a great sign!

Another on of my projects will be to reorganise the big mess in the Brisbane events on the wiki - it gets very confusing.

Questions about parking mapping

Posted by stragu on 18 June 2013 in English.

Hi all!

I had a few questions about how to map parking spaces. Here is an image of the zone, and coordinates are linked in the post:

The zone

There are two things: - The two parking lanes have the number of parking spots and the number of disabled parking spots. Should “Capacity” include or exclude the number in “Capacity:disabled”? - The highlighted point on the left, along Boggo road, is my attempt at mapping a single disabled parking space. I thought a point would be better than an area for a lone parking space, am I right? What do you think? The previous question applies here too: do I need to tag it with Capacity=1 and Capacity:disabled=1?

Cheers, and happy mapping! :)

Hi all

I was wondering: what exactly is Map Quest Open? So far, I understand that it is the side of Map Quest for contributing to OSM, but is there anything fishy about it? Or is it genuinely an effort to make people contribute to OSM with a different flavour?

I tried using it, and I like the fact that there is more space for editing (I can’t figure out how to get rid of the left pannel on OSM’s website when using Potlatch???).

However, I noticed something funny: the building type “Family house” is not recognised when editing in QMO:

Hi community!

I was an active Wikipedia contributor for a few years, and I am now contributing to MusicBrainz a fair bit. Even though I had an account on OSM for some time, I just started mapping actively around my street, which needed some love (the suburb still really does):

Around my street

I was wondering a few things, if anyone feels like helping a newbie:
