Hi there,

I am using osmar to work with open streetmap data in R. I tried to import a small area (25km²) from the german os.pbf (2.7 GB). Yet this failed due to osmosis not parsing the osm file.

System: Ubuntu 15.04, i686 GNU/Linux, 4 Cores, 8GB Ram

R: platform i686-pc-linux-gnu
arch i686
os linux-gnu
system i686, linux-gnu
status
major 3
minor 1.2
year 2014
month 10
day 31
svn rev 66913
language R
version.string R version 3.1.2 (2014-10-31) nickname Pumpkin Helmet

R-Script:

require (osmar)

setwd ("~/data/")

### Datasource
src <- osmsource_osmosis("/home/administrator/data/pgsql/osm_germany/germany-latest.osm.pbf")

### BBox
bb_sol_leipz <- center_bbox(12.359383, 51.403859,  width = 5000, height = 5000)

sol_leipz <- get_osm(bb_sol_leipz, source = src)

Just checking, but does the MD5sum of the germany-latest file match?

Hi, thanks for the hint:

md5sum -c data/pgsql/osm_germany/germany-latest.osm.pbf

md5sum: data/pgsql/osm_germany/germany-latest.osm.pbf: keine korrekt formatierte MD5‐Prüfsummenzeile gefunden

(no correct md5sum found)

Try without the -c, and manually compare the resulting checksum with the .osm.pbf.md5 file on the download site.

The error message

org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to parse xml file

tells us that it is trying to parse the file as an XML file but it is a PBF file. Download the .osm.bz2 file and try with that, or fix Osmar to use the --read-pbf flag to Osmosis instead of --read-xml.

"Unable to parse xml file" means that osmosis can open OK but can't make sense of it, which usually means a partial download (as confirmed in the comment above).
