Create map of trees

[StefanVriend]

One possible additional output is a map of the tree locations and the temperature grid cells. This may be helpful in making the audience at the LTER-LIFE Days understand what the input data looked like and what we tried to achieve.

Marcel suggested to create a map of the Hoge Veluwe which shows each tree at its location together with its bud burst date and the species to visualize spatial and species differences.

This could be combined with NDVI data or RIVM data on nitrogen.
Dependent on what further extensions of the workflow we can realise, the map can be adjusted accordingly.
