Most of you might already know that the OpenStreetMap project will celebrate its 7th Anniversary this month. Several events will take place on Saturday, 20 August 2011 at different locations around the world! You can read more about it here.

A small gift that I would like to contribute is a website which allows you to get some information about your “OSM-Age“. The functionality is similar to “How did you contribute to OpenStreetMap ?“. Type in your or any other OSM username and your or the corresponding user’s OSM-Birthday will be displayed. To be more specific the website will show your OSM-Age and your rank within the OSM contributors list. Remember: Not every OSM member contributed to OSM (cf. „Nominal Members“ of OSM). So it is possible that your rank is better than you might have expected. The date of a user’s birthday was collected from each users OSM User Wiki page (“Mapper since: …”).

The following image shows an example search result:

Additionally you can find the oldest and newest contributors in the boxes below the search results. Further you can see whose birthday it is on that specific day, or within the previous or following three days.

Soooo, what is your birthday? Check it out here: http://osmbirthday.neis-one.org

Additional information: Today (Aug. 2011) the OSM project has about 143 000 contributors with at least one edit in the database. Remember that officially the project has over 446 000 registered members (cf. OpenStreetMap stats report). I will announce more about this topic here in my blog in the near future … so stay tuned! Or you can read the blog post from last year (2010): „Nominal Members“ of OSM

thx @ *Fab* for the user-interface
and thx @ maɪˈæmɪ Dennis

Ok, you want it, you’ll get it! Maybe some of you know the nice website: www.googlefight.com. You can enter two keywords and after that it starts a funny fight between these keywords. Based on the database of “How did you contribute to OpenStreetMap?” I created a similar website where you can set up a “fight” between OpenStreetMap contributors. The following picture shows an example fight:

I am very sure you have some ideas for further fights, don´t you?
“Let´s get ready to rumble!” >>  http://osmfight.neis-one.org/ <<

thx @ Frederik for idea during a talk
thx @ *Fab* for the user-interface
and finally thx @, you know it: maɪˈæmɪ Dennis 🙂

I think most of you know my website: “How did you contribute to OpenStreetMap?“. It is a website where you can find information about OpenStreetMap contributors. You can see the first/last node the contributor placed and the amount of created nodes, ways, relations and other things.

Today I added a new diagram (1). It shows your monthly contributions to OpenStreetMap for the past 12 months as a chart and it’s based on the latest Full OSM History Planet Dump. In the following picture you can see the updates.

By clicking at “Get more Information …” (below the chart) you can see your past contributions in more detail. Separated into different categories such as created, touched and your “last modifier” OSM objects (nodes, ways and relations).

As a second update you can now see your first OSM way and OSM relation at the website (2). Check it out here: http://hdyc.neis-one.org

thx @ maɪˈæmɪ Dennis 🙂

My last blog post about the growing agreement to the new CTs is now nearly three months ago. Time for a short update: During the aforementioned time frame, about 32 contributors accepted the new CTs every day. Overall this means that since October 21 2010 there are about 43 contributors each day who accepted the new CTs. I updated my diagram with the latest numbers:

In December I conducted an analysis about the “Change of OSM object numbers through relicensing”. This time I only declared the last modifier of an OSM object (node/way/relation) as the owner of the object! The last and the new results can be seen in the following diagrams:

In my OSM-user-database of March 9th, 2011 a total of 120456* members are the “owners” of the following OSM objects (* Notice: Not every member of the OSM project (>350000 members) has contributed!):

• Number of nodes: 1007604532
• Number of ways: 85365727
• Number of relations: 899145

As of March 9th, 2011, 8124 Users have accepted the new license. 35678 new OSM members (uid >= 286582) have accept the new contributor terms automatically. I created the following numbers of OSM objects, which will be available for relicensing (if you assume that the last modifier is the owner of the object):

• Number of nodes: 801700665 (79,56%) (as of Dec. 15th, 2010 it was 66,52%)
• Number of ways: 66236798 (77,59%) (as of Dec. 15th, 2010 it was 61,68%)
• Number of relations: 716130 (79,65%) (as of Dec. 15th, 2010 it was 62,14%)

Are you still interested in any analysis regarding this topic?

thx @ Dennis

[Update – March 24th, 2011]
The following diagramm shows the above numbers of March 9th, 2011 in percent:

And again, I did a small update to “How did you contribute to OpenStreetMap ?” (http://hdyc.neis-one.org).

You can now see your ranks within the OSM World, depending on how you have been contributing to the project!

Besides the regular OSM data update, implemented by applying the planet- & changeset-dump (dated 2010-12-15), I also added two additional rows with some information about your data. In the picture below you can see your rank in OpenStreetMap (1) separated by different OSM objects such as Nodes, Ways or Relations. The rank refers to the amount of objects that have been lastly modified by you (see also row: “… are the last modifier of:”). The percentage in the brackets gives you an impression of how big your contribution to the project has been so far in comparison to the whole OSM database.

Some more information about my current database (dated 2010-12-15):

• At the moment about 111000 different users* are the last modifier in the OSM database
• Overall about 149000 contributors have created a changeset
• In the OSM database there are about 878000000 nodes, 73800000 ways and 790000 relations

*Remember: Not every member of the OSM project, which are currently more then 330000, has contributed!

I think a regular contributor should have a rank better then #14000. A really active one could have a rank better then #1000 and probably only bots are in the Top Ten. However, what is your OSM Rank ? >> http://hdyc.neis-one.org
Have fun !

Thx @ “AFK” Dennis 😉

Last weekend I added some information to “How did you contribute to OpenStreetMap ?“. The “ChangeSets” (1) of an OpenStreetMap contributor can be seen now too. To be more specific, you get the following numbers:

• ChangeSets == Overall amount of your ChangeSets
• Changes == Overall amount of your changes within your ChangeSets
• First ChangeSet == Date of your first ChangeSet
• Last ChangeSet == Date of your last ChangeSet

You can make this information visible by clicking the “more“-link (2)! In the following picture below you can see the new add-on:

Notice that the date that is shown in the ChangeSet-information field (see image above) is always the same as the date that is being displayed underneath the “Your last Node … “-image (3). Check it out here: http://hdyc.neis-one.org

In my last post in average ca. 38 members accepted the new Contributor Terms (CT) every day. I created a new diagramm which shows the increase of the accounts for the past month.

Overall for the past month every day ca. 55 accepted the new CT.

What causes the increasing support to the new license? Are more people getting familiar with the new license through publicity work? Or is it maybe Fabian´s ODbl-Map?

thx @ dennis

Because of the upcoming license discussions, I made some small additions to the “How did you contribute to OpenStreetMap?” website. First (1) I imported a new planet dump file dated 11/17/2010. Additionally the user can get the information now if the OSM contributor has agreed to the new ODbL/CT, indicated by a green “Agreed” at the bottom part of the page.

If the OSM contributor has not agreed to the new ODbL/CT yet, it’s showing a different message (3), requesting the contributor to review and accept the new ODbL/CT here.

I hope that helps and please remember: If a contributor has not agreed to the new license yet, it could imply that he/she does not know about the license changes so far!

Try it out: http://hdyc.neis-one.org/

thx @ Dennis

As I mentioned in an earlier post, since October 10th there is a list of OSM member accounts available that have agreed to the contributor terms. The file is available here and it will be refreshed every hour. I created a diagram that shows the increase of the number of accounts in the past.

So for the past 15 Days, in average, about 38 members accepted the contributor terms every day. As you can see in the figure above, there was a problem while creating the users file on the server between Oct. 29 and 31. It seems to be working normally again by now. Remember, new OSM members do automatically agree to the new conritbutor terms, so that they are NOT counted in this list!

However, I think it will be interesting to see if or how a change will be visible in the next weeks (or months?) compared to the numbers from my last post “Change of OSM object numbers through relicensing – Vers. 1” …

thx @ dennis 🙂

Since my last blog post there are some small improvements available for the “How did you contribute to OpenStreetMap?” website.

The following picture shows the changes. First (1) I imported the new full history (10/22/2010) and normal planet dump file dated 10/27/2009. Completely *new* is the second OSM map which shows the “last” contributed node of the user (2) (depending on the imported OSM planet dump file in my database). Further a link to the contributor’s page in the OSM wiki has been included (3).

So: “How did you contribute to OpenStreetMap?” Use your UserLink and share it with other OSMers or simply get some information about other OSMers!

thx @ dennis
