Purpose
This package collects data from satellites.pro. It fetches all the tiles (image and road mask pair) as given by the parameters provided by the user. This uses an API-key generated at the time of browsing the map. There are some future plans for this project, check TODO to see what this will support in the future.
The api accessKey
token is automatically fetched if you have Google Chrome or Chromium installed using chromedriver-autoinstaller
. Otherwise, you'll have to fetch it manually and set the ac_key
parameter (which can be found out by selecting one tile from Apple Map, through chrome/firefox by going Developer->Network, looking at the assets, and finding the part of the link beginning with &accessKey=
until the next &
) every 10-15 mins.
Need for scraping satellite data
Well it's good (best in the world) satellite images, we just need to give the coordinates (Lat,Lon, and zoom) to get your dataset of high resolution satellite images! Create your own dataset and apply ML algorithms :')
The scraping API is present, call it and download it.
Installation and Usages
sudo pip3 install jimutmap
# Install google chrome for chrome driver
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo apt install ./google-chrome-stable_current_amd64.deb
# optional for viewing the temporary files generated by internal databases
sudo apt-get install sqlite sqlitebrowser
Needs to have google chrome web browser in the system.
For example usage, check test.py
(venv) jimut@jimut:~$ python3 test.py

YouTube video
If you are confused with the documentation, please see this video, to see the scraping in action Apple Maps API to get enormous amount of satellite data for free using Python3.
Sample of the images downloaded
Perks
This is done through parallel proccessing, so this will take maximum threads available in your CPU, change the code to your own requirements!
If you want to re-fetch tiles, remember to delete/move tiles after every fetch request done! Else you won't get the updated information (tiles) of satellite data after that tile. It is calculated automatically so that all the progress remains saved!
