What is osmizer

Osmizer is an Python based import tool which converts OpenSidewalks specified GeoJSON sidewalks data into OpenStreetMap XML format.

Features

• Validate input GeoJSON format before conversion
• Turns any Global OpenSidewalks standard schema into OSM standard format
• Deduplicate same geometry points
• Merge multiple layers into one

Requirement

• The app is only tested on Python 3.4 and 3.5. Therefore, these two versions of Python is recommended to run the application

Installation

First clone the git repository:

git clone --recursive git://github.com/OpenSidewalks/osmizer.git

Installing osmizer inside a Python virtual environment is recommended.

To create a virtual environment and install dependencies:

cd osmizer
sudo easy_install virtualenv
virtualenv env
./env/bin/pip install -r requirements.txt

Launch the App

After installation, there are two ways to launch the application in Python 3

• From Python 3 directly

  python3 -m osmizer
  

• From modules installed by pip (to install pip, please visit here)

  pip install osmizer
  osmizer
