I have tried so many formulas for it but didn't get perfect formula for my output...

My GPS coordinates of my gazebo world of buildings are:

Building No.1  Latitude: 18.9990965928 , Longitude: 72.0000664814 , Altitude: 10.75        
Building No.2  Latitude: 18.9990965925 , Longitude: 71.9999050292 , Altitude: 22.2
Building No.3  Latitude: 18.9993675932 , Longitude: 72.0000569892 , Altitude: 10.7

I'm coding in python . Give me correct formula for converting it to X,Y,Z coordinates...

  • The x, y and z coordinates should be on which projection plane? (Remember that the earth is not flat and also not perfectly round. That makes this kind of calculations rather complex.) – Klaus D. Dec 24 '20 at 07:07
  • In my case + -0.2 error is acceptable.. – Kartik Gondhali.. Dec 24 '20 at 08:21
  • Klaus D. is right that there are quite a few subtleties, so you need to give more information. Are you working with a package that handles conversions for you? What do you mean by "perfect formula" for your output? You should edit your post to include an example of code you've already tried and the output you've gotten to show us what's wrong. – shortorian Dec 24 '20 at 08:55
  • The information in [my answer](https://stackoverflow.com/a/4325545/355230) to another question may help. – martineau Dec 24 '20 at 09:39
  • @KartikGondhali..Do you want XYZ like in a horizontal plane? If so then this would be traditionally done by converting GPS positions to East North Up (or North East Down). So you can think of East == X, North == Y, and Up == Z (gravity-ish aligned). There is also XYZ positions on a sphere/ellipsoid (Cartesian/ECEF). – user2840470 Dec 24 '20 at 16:02
