It took a while since the previous feature update to Spincloud. I have done a number of upgrades to the underlying tech and some intensive code refactoring but nothing visible. The time has come for another eye candy: heat maps. It is a map overlay that shows a color-translated temperature layer based on interpolated values of the current weather conditions. It gives a quick indication of the average temperature across all land masses where data is available. |
Naturally in areas where data is more dense, the visual representation is better. The toughest job was to figure-out the interpolation math. I still have to refine the algorithm currently based on the inverse distance weighting algorithm which interpolates scattered points on a surface. Apparently a better one to use is kriging but I have yet to implement it.
The temperature map is generated from current temperatures and is updated once every hour. You can toggle the overlay by clicking the “Temp” button found on the top of the active map area.
