What's Wrong With Bing Maps? about 11 hours ago

Have you tried other aerial imagery such as Mapbox? Both are slow to load initially, but fast once the cache is built up.

You should be able to change your location under your account in "My Settings." be sure to save the change after you move your marker.

Harry I trust you are refering to the post from make great hat.

What can I do? about 2 months ago

Rick, Lots to do. Arizona roads need lots of care. When I'm visiting my Dad in Tucson, I spend most of my time getting roads fixed. The problem was the initial TIGER import. The TIGER quality in Arizona was really bad. The good news is - it's easy to fix.

Have some fun. Join us on [Slack.](Sign up at ) Post on Facebook

And just get out and map.

Best, Clifford

Building local mapping communities 2 months ago

Joost, I just added my scripts to github to capture new users using the IRC #osm-bot channel. You can find the scripts as well as my welcome message, which came from your community.


Apartment complex addresses 3 months ago

I applaud you for adding addresses to buildings. Hopefully someday soon, every address will be in OSM.

My solution to apartment numbers is using a node with the address, including the unit number (addr:unit) inside of the building outline. The individual units will render - but only with the housenumber. Tag the building outline with the main address. Check out Parkpoint Condominiums that was done a while back.

Road Segments, naming streets and Town-land boundries 3 months ago

We had a similar discussion last night. Roads connected to landuse. I usually un-glue roads connected to landuse or admin boundaries. It would be great if editors complained when landuse, landcover or boundaries are connected to roads.

Welcome to OSM. I hope you get as much satisfaction from contributing as I do.


Let's Talk Local at the Global State of the Map 4 months ago

Mikel, Terminology is getting rather confusing. We have Local Chapters and then we have local groups. The two are worlds apart. Local groups organize to improve their community. I can't speak for all the local groups, but I suspect very few have any sort of non-profit status. Local Chapters on the other hand would have a non-profit status, by-laws, members, etc. Local Chapters are organized to put on local State of the Map conferences?

The thing is, we really don't need Local Chapters. We need local groups. Everywhere. Before everyone jumps on me for that statement, consider what we need most. More contributors. Most of those will be the result of local groups.

Let's start by asking "what do we need to do to promote more local groups." Hopefully Local Chapters will step up to play strong role in helping answer that question. But Local Chapters are just part of the answer and maybe not even a critical part.

When we talk local, let's talk local, at the community organizing level.

Like you I really look forward to hearing the outcome of the discussion. Unfortunately, I am unable to attend or would otherwise be happy to participate.

OSM editor for mapping on iOS mobile devices? 5 months ago

I'll add a third vote for GoMap!! - The developer is always looking to make the app better. On top of that he is an active mapper as well. GoMap!! works for the entire iOS line - iPhone, iPad mini, iPad and iPad Professional.

Way to go. With your list of todo's, signage, buildings, addresses, don't forget sidewalks.

Mapping lake shore 5 months ago

Looks like it could use some refinement, but glad you added the lake.

"Welcome-to-new-mappers" program in the Netherlands comes to an end. 6 months ago

I've been sending welcome messages for sometime. Late last year I modified it after the Belgium communities welcome message and included all new mappers in Washington State. Prior to that it was focused on the Seattle area and the message was to invite them to join our Meetup group.

The response rate is around 7%. I haven't looked to see how many continue to map. My guess is that number is very low.

Your assessment of is right on target. I usually don't bother even sending them a message nor a changeset comment for the less than stellar edits. I'm not blaming the person, but in the hands of a newbie is dangerous. I only hope as the app matures, it also improves. Check out Millions that Don't Care presented by Ilya Zverev,, at the 2016 SOTM-US conference. While I attended the conference, I didn't get to his talk.

I think a better approach than for each of us to send out welcome messages, would be to have a script that automatically sends a message to new uses based on their language and the location of their first edit.


1 million buildings in LA, but what about the community? 6 months ago


Only having the ability to contact one person at a time is very frustrating. We used a room full of volunteers to send message to target mappers to invite them to SOTM-US. We did get results, but it was way to time consuming.

We need the ability to: 1. Allow people to opt-in and out to receiving bulk messages. 2. Let people select interests that would allow bulk messages from others with similar interests 3. Be able to send to geographical areas 4. Send bulk message to people with similar interests. 5. Build in controls to prevent/limit spam messages like are seen on diary pages.

Keep up the great import work.


Cities by only buildings 6 months ago

Jon, Sorry I missed your talk. Can't wait to see the video.

The Latest LA data looks very rich. Do you have a breakdown of building=*?


A look into a sample of edits from MAPS.ME contributors 6 months ago

New users not responding to changeset comments is pretty common, not just MAPS.ME users. I did have one recently respond. They were attempting to add a waterfall. Unfortunately MAPS.ME doesn't have waterfall tags, so it was tagged as an attraction, and not as a node on the waterway.

They did respond, but never took the suggestion of using iD to fix their edit.

Which brings up the issue of tracking of open changeset comments. Would be nice if there were and easy way see changesets with discussions.

Sounds like a very productive meetup. Can not wait to hear more about Denver Regional Council of Government plans to import the data.
