comment Algorithm for estimating position of many objects and differentiating those?
of course I will - nonetheless I like to evaluate new options and this scenario seems to be a good situation as k-means is pretty generally applicable and I see potential for a more efficient algorithm given the specific situation

Of course - k-means is the first you stumble upon and I also used it for similar but different use cases myself. Is K-means what a GIS pro would use for this task?

comment How do you memorize the meaning of longitude and latitude?
well, that's actually wrong I think - at least if you look at the earth standing in front of you N to S.

And a third one :) Saving the layer as SVG works (I find it odd to considers this conversion as "printing") but the <path>s are lacking IDs / attributes. So I don't know what polygon represents which geographic entity and also cannot programmtically reference it. Do you know how to deal with this issue?

That did the trick - thanks a lot! Two more questions: 1) What SQL (dialect) is this? 2) How do I find out how many levels are available?
