Planet OS Exchange

We delivered a search engine for environmental sensor data called Planet OS Exchange.

I learned a lot about maps visualization and sensor data. Here is an early prototype.

That's where I developed Cirrus.js. Most data we currently have is raster data, but there's always the occasional time series.

And temporal coverage chart.

But most of the visualization work is on map polygons and raster data. Here is for example a screenshot of the colour palette dropdown.
