osmconvert border problem

Question

I tried to add a border to my osm file to make is smaller.

The command line is as follows:

osmconvert china.osm -b=22.30,114.11,22.38,114.22 --out-osm -o=hk.osm

an error occurred like this:

osmconvert Error: use border format:  -b="x1,y1,x2,y2"

I then tried following the border format by adding the two colons but still same error

Answer 1

You have swapped X and Y.

Try with

osmconvert china.osm -b=114.11,22.30,114.22,22.38 --out-osm -o=hk.osm
