What the Demo Does

What does the demo do?

It launches a server that displays the current heatmap at http://localhost:8000/web/crowdReporter3.html. This map automatically updates every five seconds.

You can display four different kinds of map:

1. Predictions based on report locations only.
2. Uncertainty based on crowd reports only.
3. Predictions using HeatMapBCC to interpolate between report points, predicting the damage rate across the whole area.
4. Uncertainty in the heatmap produced by HeatMapBCC.

The demo server also simulates the influx of reports from the crowd by adding a new report every 10 seconds, then recalculating the heat map.

You can submit a new report using the web page. This allows you to enter the prior trust of the source, by specifying how accurate you think they are and how certain you are about their accuracy. Thus, for a highly trusted source, you can enter a report that is treated similarly to ground truth. This report is then used the next time the heatmap updates itself.

The maps and reporting interface can also be accessed programmatically using the HTTP interface..
