out of curiosity, can you say a few words on how your overall approach
to calculate centroids for ways? As we all know it's an endless pain to
get that information out of minutely diffs :)
I have to say that I'm pretty much unfamiliar with SPARQL and just tried
the following query. My expectation was that I won't get any results,
making me wonder if my query has some issue?
SELECT * WHERE {
?osmId osmm:type 'w' .
FILTER NOT EXISTS { ?osmId osmm:loc ?osmLoc }.
} LIMIT 100
BTW: A quick search on Github yielded the following:
https://github.com/nyurik/osm2rdf. Would that be the right place to look
for more details?
Best,
mmd
