For our Iceland trip in Summer we had decided to go camping and purchase the camping card. The camping card offers a large number of possibilities across whole Iceland for a reasonable price. Since Iceland is comparably expensive, this might be a real consideration for most of travellers that want to go camping.
Although the page offers a good overview of all camping places, I wanted to have them offline on my mobile phone. Thus I wrote a small python script to extract the data form the website and extract it as GPX track, that I could easily import into OsmAnd (the app I use for navigation and maps)
