In the previous Blog Agroclimatic factor of interest: Frost-free period, frost dates we have already presented a workflow of how we calculate an agro-climatic factor of frost dates here on this blog. Now we would like to introduce you first draft of a 4D application, which visualizes another agro-climatic variables, length of growing period for C3 types of crops (red bar) and length of growing period for C4 types of crops (green bar). It is a 3D visualization of the factor at the area of Pilsen region in the Czech Republic, combined with a temporal part of data, showing such a factor by particular years (see the time bar at the bottom of the following video).

The first draft of the application is available here:
