Quick Start

1. Install the package via pip:

pip install pygmdl

2. Import the package and use it:

import pygmdl

lat = 35.681236
lon = 139.767125
size = 2000
output_path = "satellite_image.png"

pygmdl.save_image(lat, lon, size, output_path)

It will took a while to download the image, but as soon as it's done, you will see the image in the specified path.

Overview

This package is designed to download satellite images from Google Maps in a simple way. This repository is a fork of satmap_downloader, which provides CLI to download satellite images. So if you need a CLI tool, please use the original repository.

How to Use

Here, you'll find the detailed explanation of the save_image function.

Function signature

def save_image(
    lat: float,
    lon: float,
    size: int,
    output_path: str,
    rotation: int = 0,
    zoom: int = 18,
    from_center: bool = False,
    logger: Logger | None = None,
) -> str:

Note, that by default the function expects that provided coordinates (lat, lon) are coordinates of the top-left corner of the image. If you want to provide the coordinates of the center of the image, you can set from_center to True.

Function arguments

Parameters	Type	Description
lat	float	Latitude of the point to download the image from.
lon	float	Longitude of the point to download the image from.
size	int	Size of the ROI in meters.
output_path	str	Path to save the image.
rotation	int	Rotation of the image in degrees (CW).
zoom	int	Zoom level for images (higher values = higher resolution).
from_center	bool	If True, the provided coordinates will be treated as the center of the image.
logger	Logger | None	Logger to use for logging. If None, the default logger will be used.

Return value

The function returns the path to the saved image (the same as output_path).

Usage example

import pygmdl

lat = 35.681236
lon = 139.767125
size = 2000
output_path = "satellite_image.png"
rotation = 25
zoom = 16
from_center = True

pygmdl.save_image(lat, lon, size, output_path, rotation, zoom, from_center)

As a result, you will get the satellite image of a region 2000x2000 meters around the point with coordinates (35.681236, 139.767125) with the center of the image at these coordinates. The image will be rotated by 25 degrees clockwise and will be downloaded with zoom level 16.
