Indian Grid Converter

A Python library for converting WGS84 latitude and longitude coordinates to the Indian Grid System and vice versa.

Features

• Convert WGS84 latitude and longitude to the Indian Grid System.
• Convert Indian Grid System coordinates back to WGS84 latitude and longitude.
• Accurate calculations based on the Indian grid system parameters.

Installation

You can install the package using either of the following methods:

Using pip:

pip install indiagrid

Installing from GitHub:

pip install git+https://github.com/goki75/indiagrid.git

Usage

Converting WGS84 to Indian Grid System

from indiagrid import wgs84_to_igs

result = wgs84_to_igs(lat=28.7041, lon=77.1025)
print(result)

Output:

{'Easting': 3632281.67, 'Northing': 531791.54, 'Grid': 'I'}

Converting Indian Grid System to WGS84

from indiagrid import igs_to_wgs84

reverse_result = igs_to_wgs84(3632281.67, Nth=531791.54, grid="I")
print(reverse_result)

Output:

{'latitude': 28.704099993002522, 'longitude': 77.10249995658076}

Parameters

wgs84_to_igs

• lat (float): Latitude in decimal degrees.
• lon (float): Longitude in decimal degrees.
• esterr (float, optional): Easting error adjustment. Default is 0.
• ntherr (float, optional): Northing error adjustment. Default is 0.

igs_to_wgs84

• Eth (float): Easting in the Indian grid system.
• Nth (float): Northing in the Indian grid system.
• grid (str): Grid region (e.g., 'I', 'IIA', etc.).
• esterr (float, optional): Easting error adjustment. Default is 0.
• ntherr (float, optional): Northing error adjustment. Default is 0.
