Oslandia/building-server

Repository files navigation

This is a prototype for a simple web server that retrieves polyhedral surfacesfrom a POSTGIS database and sends them back in a glTF or GeoJSON file.

It relies on a Bounding Volume Hierarchy (BVH) to transmit progressively thegeometric data. A script for building the BVH is provided in this repository.

Installation

From sources

To use building-server from sources:

$ apt-get install python3-dev$ git clone https://github.com/Oslandia/building-server$ cd building-server$ virtualenv -p /usr/bin/python3 venv$ . venv/bin/activate(venv)$ pip install --upgrade setuptools(venv)$ pip install -e .

If you want to run unit tests:

(venv)$ pip install nose(venv)$ nosetests...

Generating the BVH and the tile association

./building-server-processdb.py conf/building.yml <city>

How to run

building-server has been tested with uWSGI and Nginx.

Once filesbuilding.uwsgi.yml andbuilding.yml are well configurated for yourenvironment, you can run the building-server:

(venv)$ pip install uwsgi(venv)$ uwsgi --yml conf/building.uwsgi.ymlspawned uWSGI worker 1 (pid: 5984, cores: 1)

In case of the next error:

(venv)$ uwsgi --yml conf/building.uwsgi.ymlImportError: No module named site(venv)$ deactivate$ . venv/bin/activate(venv)$ uwsgi --yml conf/building.uwsgi.ymlspawned uWSGI worker 1 (pid: 5984, cores: 1)
