How to convert latitude and longitude of location to cartesian coordinates (x, y)?

31 views (last 30 days)
Dear Sir,
Is there a feasible way of converting (lat, long) coordinates into cartesian corordinates (x, y) of respective locations?
For instance, i want to convert (27.2046° N, 77.4977° E) coordinates into (x, y).

First, you need a reference point. Second you have to assume that the posints are close enough to the reference points so that the spherical coordinates on earth surface (lat, lon) can be approximate in cartesian coordinates.
With these assumption, you can do the following:
ref = [27, 77]; % ref point [lat, lon]
p = [27.2046, 77.4977];
[arclen az] = distance(ref, p)
arclen = 0.4880
az = 65.0993
x = deg2km(arclen.*cosd(az));
y = deg2km(arclen.*sind(az));
[x, y]
ans = 1×2

"doc distance" for more details.
You can use the center of of data points as the reference point.
