on opensuse 13.1 i try to do some gis-works with a large file: france-latest.osm.bz2 which i gathered from here:
http://download.geofabrik.de/europe.html
what do i do with that file france-latest.osm.bz2
bzcat france-latest.osm.bz2
what is aimed? i want to extract all things that belong to the POI restaurant which is
Quote:
long lat
name
adress
etc - etx.

my trials:
the very first attempt to do the job: i have the following things up and running:
Code:
package perl-XML-Twig and run xml_split
with a command available on openSUSE to split xml files named xml_split (it is part of the package perl-XML-Twig)
Now we try to run the following command (I hope we have enough hard disk space since the output is roughly 20GB).
Code:
bzcat france.osm.bz2 | xml_split -s 100M -b france -n 3 -
the second attempt:
well i think i will go and extract (an initially small) geographical area using osmosis,then i will go to look at osmfilter to extract the data (possibly having a look at osmconvert to convert the data into a format that osmfilter can understand). Also perhaps consider osmium.
well - i need to run osmosis and osmfilter
besides this i need to have osmconvert
are these packages available for opensuse
btw: i did it - see here

btw regarding the two other toools osmconvert osmfilter - i have had a loook at the corresponding websites.should i have to install it like it is written on here :
PHP Code:
Download and build in one run: wget -O - http://m.m.i24.cc/osmconvert.c | cc -x c - -lz -O3 -o osmconvert
and
PHP Code:
Download and build in one run: wget -O - http://m.m.i24.cc/osmfilter.c |cc -x c - -O3 -o osmfilter
what do you say - well i need a example where i can run osmconvert and osmfilter - in order to have good and valid examples
so i finally am sure that i have all the ingredients on my machine to work
