This python script traverses through all the images in the sepcified directory and gives us a heat map using the gps location present in those images metadata.Since EXIF metadata are present only in .jpeg files, so this will work only for jpeg/jpg images. Along with giving us the heat map, it can also print out the metadata of each image which sometimes proves extremely useful during an investigation.
Pillow library was used for getting the exif metadata and Gmplot was used for plotting of the heat map.Gmplot provides us with many different options for plotting of those points and you can read about it more at https://pypi.org/project/gmplot/.
Data-set used here was take from the following link https://www.kaggle.com/jbakerdstl/geolocated-imagery-dataset-scotland.
