[Tagging] Planning route in the shade during hikes either in urban areas or forests

[bkil]

Could you perhaps share your reasoning or what needs to be improved
for you to accept it or could you propose a better alternative?
Estimating the direction of sunlight around noon in the summer based
on GPS coordinates doesn't sound like rocket science to me. Do you
have any other concern that was not already answered in the above
thread?
