We can use the Haversine formula to calculate the distance between two points given their latitude and longitude coordinate. The Haversine formula is a mathematical formula that is used to calculate the great-circle distance between two points on a

In the following distance calculation function, I use thehaversine formulato calculate the distance between two points on the Earth’s surface, feeding it the latitude and longitude of both points. The calculation is a bit tricky, so I won’t describe it in details. Rather, let me just give...
Given two points A and B on the sphere expressed by latitude (lat) and longitude (lon) you will have: distance (A, B) = R * arccos (sin(latA) * sin(latB) + cos(latA) * cos(latB) * cos(lonA-lonB)) The angles used are expressed in radians, converting between degrees and ...
Unfortunately I'm getting a little frustrated. I am using .net standard 2.0 with GeoAPI 1.7.5, NettopologySuite 1.15.1 and ProjNet4GeoAPI 1.4.1 I am trying to get the distance between two latitude/longitude points in meters that I know t...
