[OSM-talk] osmosis --tee and heap space

[Martijn van Exel]

Hi there,

I am trying to cut a large number (hundreds) of polygons out of a
planet file, using the --tee option in osmosis to do it all in one go.
It fails with a heap space error. My heap space is set to 2G. My
command looks like this:

osmosis-0.39/bin/osmosis \
--rb planet/us-110821.pbf \
--tee 512 \
--bp file="poly/us_metro_central_cities/Abilene.poly" \
--wb file="out/Abilene.pbf" \
--bp file="poly/us_metro_central_cities/Aguadilla.poly" \
--wb file="out/Aguadilla.pbf" \
--bp file="poly/us_metro_central_cities/Aiken.poly" \
--wb file="out/Aiken.pbf" \
--bp file="poly/us_metro_central_cities/Akron.poly" \
[.......]
--bp file="poly/us_metro_central_cities/Yuma.poly" \
--wb file="out/Yuma.pbf"

What I'm trying to do is extract OSM data for each of the central
cities of the US metro areas[1]. If there's a better way to do that,
I'd love to hear about it.
