osm-combine

Combine OSM files through osmconvert and NodeJS

Installation

npm i -g osm-combine

Summary

This is designed to quickly combine osm.pbf files without manually writing out the pipe commands or making intermediate files. All you need is a list of files in a JSON array to process. The idea is that, if you have a workflow that demands this kind of process multiple times a day/week, it should save you time.

Simply run osm-combine in the directory with osm-combine.json and it will process the files, creating a new, combined file in your current working directory.

Note

This will download osmconvert to a ${__dirname}/osmc, but it will not add it to your $PATH.

osm-combine.json

Below is an example of osm-combine.json:

{
  "files": [
    "/path/to/new-brunswick-latest.osm.pbf",
    "/path/to/prince-edward-island-latest.osm.pbf",
    "/path/to/alberta-latest.osm.pbf"
  ]
}

Note that these are absolute paths, but relative paths are supported.

Example command and output:
