A couple of months ago, Google Maps quietly added a Terrain layer to their maps. I’ve enabled that in OurAirports now, so that you can get at least a rough idea of the terrain around an airport (or in a region, country, etc.).
For example, here’s why there are so many accidents around Hope, BC when the weather gets low.
I’ve finally gotten around to adding free data downloads to OurAirports. You can now download nightly CSV-formatted data dumps of all the airports, countries, and regions in OurAirports at

These will open with most spreadsheet and database programs (make sure you import them as UTF-8).
All data is released into the Public Domain and comes with no warranty. If you have any corrections or additions, please make them in the spreadsheet and then send them back to me.
