Current location as measure of feet from man was inaccurate #138

When looking at your current location as clock time and feet from man, the distance from man calculation was way off numbers were about 50% higher than they should be. man to a point on trash fence should be 8175’

Hmmm yeah you're right! I tried Point 1 - 40.782814, -119.233566 from here https://bm-innovate.s3.amazonaws.com/2023/2023%20BRC%20Measurements.pdf and it shows it as 7:12 & 13535' from the man. On the bottom of that document it says for this year the points should be 8,430' from the man Simulator Screenshot - iPhone 14 Pro - 2023-08-06 at 07 59 00

If you're able to help us debug, the source code for the geocoder is here: https://github.com/iBurnApp/BlackRockCityPlanner/tree/master/src/geocoder and our layout file is here: https://github.com/iBurnApp/iBurn-Data/tree/master/data/2023/layouts

Do you have a script that builds those layout json files from the 2023 API?

chrisballinger commented 11 months ago

That layout file is actually artisanal hand crafted JSON, it is used to generate GeoJSON and also within the geocoder
