 Due to the large amount of information, the data folder can be a bit confusing, so here is a brief description of what each folder contains:
 
-* data/driving_distances:
-  * A set of csv files containing the driving distances between some pairs of points in the dataset. The files are named as follows: `driving_distances_{dataset_name}.csv`. The dataset name is the same as the name of the folder containing the dataset. 
-* data/shapefiles: 
-  * `los_angeles_majors`: Shapefile containing the major neighborhoods of Los Angeles.
-  * `los_angeles_minors`: Shapefile containing the minor neighborhoods of Los Angeles.
-  * `guarulhos_osm` : geospatial data describing boundaries of all neighborhoods of the Guarulhos city. source: _OpenStreetMap_
-  * `urban_regions_Sao_Paulo`: geospatial data describing land use over state of Sao Paulo. source: unknown
