In 2015 the company “Isocal” assigned me with the project “Eisspeicher”  – a webapplication to visualize the temperatures at certain control points in a huge geothermal heating and cooling system.

The temperature data was retrieved from heat cameras and a php-script read the input csv-file and displayed the numbers generically on a graphic. It was accessible over the internet as a webapplication. A statistic of old temperature data was stored and could be displayed. Thus, the webapplication could be used as a controlling system.
