I need to figure out how to convert my xy coordinates to longitude and latitude.
I do not need the exact conversion, just an approximate so I can plot it in a mapping API. I managed to estimate the following xy to long-lat:
(x, y) = 24050, 123783.3333 -> (long, lat) = (122.98, 24.46)
(x, y) = 24216.6667, 123933.3333 -> (long, lat) = (122.985339, 24.46041)
Can I somehow use these to come-up with a formula to convert the other xy points?
I found another link that does what I want, but I cannot extract the formula:
In the above link, I specify the origin of xy in lat-long coordinates, and it was able to convert xy to lat-lang
