Assignment 3 -Spatial data

For this assignment, I treat it as a chance to learn new tools in class, such as mapbox.


Public surveillance and privacy is a hot topic today, so I was wondering the surveillance camera setting in this big city. Is it covered everywhere? Is it too dense to cause concern?


1. Download data from here into google sheets

2. Translate address to coordinates in google sheets with tutorial from here

3. Visualization and editing in Mapbox


Final outcome



The translation from address to coordinates is definitely inaccurate, which needs to improve by a new solution.

The  visualization choices in Mapbox is very limited.

Data is not verified. (Should we consider the verification of data source when we use it? )
