Google Maps Static API Image Downloader

Simple tool to download image tiles from Google Maps via the Static-Maps API and Merge them back together using GDAL API.

How it works

• All parameters are set by defautl can be modified on the code: such as the tile size which is set to 1024*1024, the zoom etc
• The tool calculates how many individual image tiles it needs to get from Google's Static-Maps API and begins to download them
• All image tiles are stitched together and a preview showed onscreen
• The image is also saved to a file
