As interest in czml continues to rise, we need to make sure the barrier to entry is zero. As we discussed on github (apparently github doesn’t let us search pull request comments), I believe we need a command-line tool that converters from all supported formats, i.e., any format that a converter exists for, to czml. This could be used for scripting servers, and as a standalone tool. I suspect the implementation is trivial, and given Kristian’s commitment to supporting the widest possible content with the lowest barrier to entry, I’m sure he’d love to code it.
As part of this effort, we should also host a REST web service that converts from supported formats to czml. Perhaps this can be built on the web service that converts czml to kml?
