Re: Shade Map
#53Ha! A friend and I had this idea ages ago when living in Austin. I actually have the domain “walkdarkly.com” registered for it, in case I ever got around to it. If somebody actually doing something with it wants the domain, I’m happy to talk about transferring it
This hints at a hiking trip planner maybe?
Depending on time of day and year evaluate a path to be in the direct sun/shade?
In summer, I might want to avoid the direct sun. Suggest the hiking path with least direct sunshine. And if it is autumn already, then please suggest a hiking path to be in the sun all day.
Might be a cool feature to compare hiking paths by percentage of direct sunshine.
But maybe, selecting a path through a forest vs. across open fields might already do.

#54Earlier quoted context omitted.
I've seen the setting, and I've seen that you suggest toggling it when tree shadows seem inaccurate, can you elaborate on what that setting does exactly?
"Top of canopy" - view from above like looking down from an airplane window. You won't see any shadows looking down on a forest because you only see sunlight landing on the top of the canopy. Most accurate. "Below canopy" - what shadows would look like on the ground. If you're in a dense forest everything is in shadow because the trees obscure the sun. I guesstimate how big and where the below canopy shadows land. An…
Hmm, maybe I'm missing something, but what's the difference between "top of canopy" and "No trees" then?

#55This tool uses OpenStreetMap data for the buildings and base layer. Unfortunately, it kind of hides that it is doing that, which sucks. Usually the required attribution is placed in a corner of the map. Shade Map has a little information-i there which does appear to list OpenStreetMap according to my browser's dev-tools, but it seems to be broken and gets hidden behind other page elements, so only '© Shade Map |' is…

Re: Shade Map
#56This doesn't look particularly accurate, at least not relative to what I can see right now out my window.
Website creator/maintainer here. Happy to try and diagnose the error if you elaborate on what the discrepancy is (tree, building, hill, etc)...
Would just like to say thank you so much for this tool! Ended up finding a quieter park to watch the eclipse last night.

Hi! I've recently made a shade calculator specifically for climbs in North wales:

It's important for me to use accurate height-maps as (obviously) the terrain is very three dimensional.
Are you using the public LiDAR data as well?

#60https://en.wikipedia.org/wiki/Manhattanhenge There a street in Manhattan that, during a certain time of year the light shines all the way down the grid of buildings. Here's the link to that moment https://shademap.app/@40.7426,-73.9841,13.48594z,17839875468...
Shameless plug: been working on https://www.streethenge.com for sometime. You type in a street and it shows whether the sun ever aligns with it at sunrise or sunset, and when (date, time, compass bearing). Works with the moon as well.
Here's the page for Manhattanhenge: https://www.streethenge.com/henge/new-york
It works for any street, and there's an add to calendar button for the next alignment. One warning: street lookups go through public OSM APIs, so the occasional query can time out due to api limits. I haven't figured out what to do about that yet without exponentially increasing the size of the app.
