Show HN: Every mountain, building and tree shadow mapped for any date and time

I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer any questions.<p>[1] <a href="https://www.nature.com/articles/s41559-023-02206-6" rel="nofollow">https://www.nature.com/articles/s41559-023-02206-6</a>

Show HN: ChatGPT UI for rabbit holes

I was inspired by the way ChatGPT writes bullet lists, then invites you to "delve" deeper.<p>This is an interface that reifies that rabbit-holing process into a tiling layout. The model is instructed to output hyperlink-prompts when it mentions something you might want to delve into.<p>Lots of features to add (sessions, sharing, navigation, highlight-to-delve, images, ...). Would love to hear other usecases and ideas!
