I think we need a abspath(expanduser(path)) somewhere, at least for local files...

[felixcremer]

Is this the same also for other file types?

[asinghvi17]

Same for GDALsource on that file

If I call expanduser on the string first, it works in both cases.

[rafaqz]

Lets add abspath(expanduser(path)) then. Probably we need a better path handler function

[asinghvi17]

Well we have to handle urls, http, etc too

[rafaqz]

Yeah, probably why it doesn't work yet!
