OpenStreetMap GPS point data visualization

This repository hosts code and outputs of a visualization work about the density of GPS points from the OpenStreetMap bulk dataset.
Beside creating a gray scale bitmap of this, we superimposed it with the visualization of world border dataset and NASA city light images in order to compare the OSM contributions density with some data which hints about earth civilization.
