Re: which way is the sun?
Eddie E says "Hence, the shadows would depend on your local light source, not on the light source at the mapped location"
Yeah, i'd thought of that one. I always have my desk lamp pointing at my work from under my left arm pit to throw a shadow to the upper right. Which would give me a shadow to the nor' east while I'm sitting at my desk. But perhaps not so much in the back o' beyond while I'm trying to drive to the Isa. Or Mildura.
I did have a bit of mental confusion as to what time of day would lead to a nor'east shadow in the outback. But then i thought "If I was in a car on my way from Tennant Creek to Mt Isa, that is local to me" and so in the morrning, the shadow should be W to SW and in the arvo SE to E. And as Eddie says, at night pretty dark so not much shadow. Or light!
My original point was probably that the application is saying "we're not from these parts", which should be a warning. But a bit too subtle for those people who having paid for a software bundle, think that an application should be fit for purpose. Which it doesn't seem to be.
Need a beer after thinking that hard
