Getting started with OS OpenSpace FAQs

How do I start using OS OpenSpace?

Register for your own application programming interface (API) key.

Registration will require you to click accept the terms of the OS OpenSpace Developer Agreement and tell us the URL of where your map will be used. Once you have done this we will email you the details of your API key and then you are ready to start developing your map.

Take a look at our getting started guide, sample code and tutorials to see how to start building your first application and to get the most out of OS OpenSpace – or take a look at the gallery to see other applications.

Is there any special software I need to get started using OS OpenSpace?

No. To use OS OpenSpace all you will need is an internet Browser and Notepad or another text file program (to edit and save your code).

I have never developed a web application before. Are there any tools to help me?

Yes. We offer Web-Map Builder, a tool that will create all of the code for you. All you need to do is decide what size map you want, add your information and click to generate the code.

Once you have created the code, you will need to copy it into your website editor. We have published a series of tutorials which will help you to embed the code into various blog and website editing applications.
