# 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:
```bash
pip install indiagrid
```
### Installing from GitHub:
```bash
pip install git+https://github.com/goki75/indiagrid.git
```
## Usage
### Converting WGS84 to Indian Grid System
```python
from indiagrid import wgs84_to_igs
result = wgs84_to_igs(lat=28.7041, lon=77.1025)
print(result)
```
**Output**:
```python
{'Easting': 3632281.67, 'Northing': 531791.54, 'Grid': 'I'}
```
### Converting Indian Grid System to WGS84
```python
from indiagrid import igs_to_wgs84
reverse_result = igs_to_wgs84(3632281.67, Nth=531791.54, grid="I")
print(reverse_result)
```
**Output**:
```python
{'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.
