Java application to serve traffic data from NDW in a friendly format

## Usage in QGIS

The software presents a shape file in GeoJSON format that can be imported into QGIS.

Each point in the GeoJSON represents a measurement site,

and contains all properties of the original shape file,

plus URLs to the static data (fixed properties), dynamic data (traffic speed and flow) and a link to Google streetview.

First, add an openstreet background layer,

by clicking XYZ Tiles / OpenStreetMap

![QGIS Add openstreetmap](images/qgis_osm.png)

Then, add a vector layer,  by opening menu

Layer / Add Layer / Add Vector Layer ...

![QGIS Add vector layer](images/qgis_vectorlayer.png)

The URL is https://stofradar.nl/traffic/static

Click 'Add', then 'Close'.

You should now see all measurement sites on the map.

Select a particular site using the 'Identify features' button.

![QGIS Add vector layer](images/qgis_identify.png)

This shows the static information about the measurement site,

including an URL to the dynamic information. For example:

http://stofradar.nl:9002/traffic/dynamic/RWS01_MONIBAS_0121hrr0292ra

The URL to the SSE event stream has '/events' appended:

http://stofradar.nl:9002/traffic/dynamic/RWS01_MONIBAS_0121hrr0292ra/events
