I'm using osm.nl too but I'd need to move the Europe set (too much bandwidth). Maybe Lambertus has some space left on his server to store a European srtm set? If someone would like to generate one I'd be happy to host it on my google docs account.

Sorry Ligfietser I missed this question 🙁

I'm interested in trying to host the SRTM tiles for Garmin map purposes for the whole world (I hope my sponsor won't mind the significant extra bandwidth usage that most probably comes with it), preferably already splitted into usable tile sizes. One of the servers has a partition with 380 GB free diskspace. I hope that all the SRTM data in OSM PBF or OSM XML.7z format will be small enough to fit.

As I understand, from the discussion between you and Kukuk above, the creation of the ready-to-use tiles is a bit tricky. I'm thinking of using Phyghtmap for downloading the data in large PBF chunks, merge the osm files with Osmosis into a planet and then use Splitter to create suitably sized tiles. Can you or Kukuk tell me if this could work? What are the pitfalls?

A few specific questions:
- What is a useful interval of the contour lines, 20 or perhaps 50 meters?
- What base ID should be used for the nodes and ways?
- Is incorporating viewfinderpanorama data useful?
- I found this wiki page that describes how to properly process the SRTM data. Seems quite complex to me, is it necessary?
