OSM Stats for Namibia

Ever wanted to explore OSM statistics over time and in depth? OSM Stats is for you. Notice the site asks for your location – this is just to show you your country automagically by default.

The site lets you explore by country, over time, major types of OSM data. The left-hand graph shows you the aggregate count over time, the right-hand graph shows the difference (delta) over the same time period. You can click different data types on the left, change country at the top, and change the time range just above the graphs.

You can find some interesting things. Here’s the default view for the United Kingdom:

What it shows is data growing over time. We like graphs that go up-and-to-the-right. The right-hand graph shows, as expected, the amount of data being added declining over time. This is because there’s less and less to map in the UK as I started the project there.

Compare that to Haiti:

Can you guess what the spikes in data addition are?

Now look at residentialĀ roads only in the United States:

Things are declining over time! Where are all those residential roads going? Well a small part of the answer (notice the vertical axis is 2 orders of magnitude less than above) is the growth of living streets in the US:

That’s a small taste of the things you can learn – have fun exploring the site and email me any comments.
