You may wish to actually get at the data in OpenStreetMap and extract a spreadsheet of information – not just latitude and longitude but also every detail about each point of interest or feature.


OpenStreetMap is a terrific tool for mapping and editing maps. It is a user-created map of the world, made by thousands of participants over the years. The structure is much like Wikipedia – anyone can edit the map, and users correct each others’ errors so that the results you see are highly accurate.

Adding your own map information to OSM is covered here.

Often, you’ll want to take part of the map you see on the OSM site and use it somewhere else, like on your website or blog as an illustration. This tutorial focuses on taking a map image off of the main OSM site so you can use it someplace else.


Make sure that the area you want to show on your map is actually mapped well before you start. You can follow the first step of the tutorial to find out. If it’s not go ahead and add your own information.

You may wish to actually get at the data in OpenStreetMap and extract a spreadsheet of information – not just latitude and longitude but also every detail about each point of interest or feature. Remember, there can be a lot in the OSM database that isn’t immediately visible – say, opening hours of a clinic or really anything someone wished to add. In order to do this, you should see It is not covered in this tutorial.

Starting a new Map

First, go to

There is a search box on the lefthand side of the homepage. You can type in there the name of the place you want to find on the map. A list of options will come up and if your area is mapped, it will appear there. Click on it to get to the part of the world you want to capture.

Or, you can zoom in and out of the map using the righthand side + and – buttons, and click and drag the map around using your mouse to find your part of the world. If it’s not well mapped, you might want to map it first yourself! Use the tutorial or else, see Learn OSM to get into more depth with mapping.

Once you’ve found the place you want, your screen should look something like this:

You don’t even have to log in to take this data right from the website to your computer desktop. First, drag the map around and zoom in and out to show the exact area that you are going to want. Click where it says Export.

The latitude and longitude coordinates shown will correspond to the edges of the actual map image you see, so you can leave them alone since you already adjusted that.

Formatting your map

Where it says Format to Export, at this point we just want an image file so you can leave it on Map Image. Below, choose your preferred format to export.

Where it says Scale, you might need to experiment with the size. The Maximum is given, and if you type in that exact number (in my example, it’s 21000) you’ll get every tiny bit of data in that box and a fairly large file size. The number given in my example is 65272 (actually less than 21,000 because it’s a ratio 1:x) will give you a fairly small file size and image, so if you zoom in it becomes pixelated. Choose the size that best works for your particular needs, and hit Export. That’s all – now you have a nice image to put on your blog post or website – or a printed document of any kind.

If you want to get a little more advanced, and use the HTML code, you can also place a marker onto the map and then put the code into your website directly.

Click where it says Embeddable HTML.

If you want, click where it says Add a marker to the map and click on the map to add a little pointer.

Then copy-paste the HTML displayed in the box into your website.

That’s it!
