A WSGI Server to calculate a route based on an OSM-File.
Used for the backend of an OpenLayers-Visualization.
Currently it only connects crossing nodes of streets/way, so the sampling of the route isn't that good.

Install

Install Python

Download & install Python(>=3.6) -> Python Downloads.

Install Python packages

Run the "INSTALL.bat"
OR
run the following command in the project folder: pip -R install requirements.txt

Download an OSM-File

Download an OSM-File of your region. Keep in mind that big OSM-Files can take a long time to process.
Example download sites: https://download.geofabrik.de/, https://www.openstreetmap.org/export.
Name your OSM-File "map.osm" and override the current "map.osm" in the project folder. Alternatively you could just change the "osmPath" variable in the "server.py" file.

Run

Development Mode

Run the "START.bat"
OR
run the following command in the project folder: set FLASK_APP=server && flask run -p 5555 --with-threads

Production Mode

To run the server in production mode, you must deploy the server correctly on your system.
Flask Documentation | Deploy

Usage

The Server has those following URLs which all respond in a JSON-Format
If you have any problems try to delete your "map.db" and let the server regenerate it!

ATTENTION: First Run

When you run the server for the first time and no "map.db" got generated yet, it may take a while before the server starts.
Thats because the "map.db" has to get generated and this can take a LONG time based on your OSM-File & your computer.

Get route based on ways

http://localhost:5555/getRoute/%fromWay%/%toWay%/
fromWay & toWay: AN OSM wayID.

This responses with a JSON-File this following structure:

Find ways based on name

http://localhost:5555/search/%query%/%limit%/
query: The street/way name with autocomplete. Example: http://localhost:5555/search/F/%limit%/ -> gives you "Foster Street", "Friday Street" etc.
limit: The limit of results which should come back. This responses with a JSON-File this following structure:
