I want to use osmconvert to parse down the size of my diff files for just the area I'm interested in because osmconvert is way faster than osm2pgsql, which loads the data.
When I call the command using os.system() like such:
cmd = r"""c:\temp\osmconvert.exe 770.osc.gz -b=1,1,3,3 -o=extract.o5m"""
os.system(cmd)
I get osmconvert error: cannot open file
When I run the same exact command from my command prompt in Windows 7, it runs fine. What is python doing to prevent this function from running? The 770.osc.gz file lives in the same directory as osmconvert.exe and the output extract.05m should populate in the same directory as the osmconvert.exe exists.
If I put the command in a batch file, it works, but I want to use python to download the file from the server so I can automate the updates of the database.
