Tracing devices may send up to 140 messages per day in Sigfox network. It is about 4.200 positions per month and 51.100 per year. Imagine you want to visualise the movement over the last 12 months…It is impossible to download and render so many pints in the map. And if we were able to do it, you would see thousands of points and poly lines that would hardly give you any benefit.
IO Frog is now processing location based messages using Ramer–Douglas–Peucker algorithm to significantly reduce the number of points that may be less important because of high proximity. The result is a possibility to visualise thousands of tracing points in one map.
