<div dir="ltr">I fundamentally do not believe that shade is geospatial data, it is a characteristic that is derived from the physical location of objects in the world. I do not believe that there is a way to make the proposal workable if it includes a mapper making shade observations. The only approach that might be feasible is to map the physical qualities of the foliage and structures around a path, which could then be used algorithmically to come up with a shade calculation (as is done with the pubs in the shade concept).</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jul 16, 2021 at 1:46 PM bkil <<a href="http://bkil.hu">bkil.hu</a>+<a href="mailto:Aq@gmail.com">Aq@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Could you perhaps share your reasoning or what needs to be improved<br>

Estimating the direction of sunlight around noon in the summer based<br>
on GPS coordinates doesn't sound like rocket science to me. Do you<br>
have any other concern that was not already answered in the above<br>
thread?<br>
