Usage

  1. Configuration API key

    In sample_settings.json, It is needed to fill your google street view API key in GOOGLE_KEY field. Detailed information about google street view API key can be found here. The DISTANCES field means the distances between each viewing point to the object. [10, 20] means we have totally 5 points to that points each are the nearest point on the road to the object, two points 10 meters away from the nearest point to the object and two points 20 meters away from the nearest point to the object. The FILE field is the required .csv file directory which is detailed explained in data preparation. The ROOT_FOLDER is the directory to save all the parsed images.

  2. Data preparation

    To successfully running the code, a .csv file containing all the coordinates must be provided in settings' FILE field. This file containing all the coordinates to be parsed from google street view. A sample format of a .csv file is provided and shown below.

    stop_name,         stop_lat,      stop_lon
    "Bird Ave",        37.325184,     -121.900520
    "BSan Carlos",     37.324215,     -121.900337
    "Diridon Station", 37.330338,     -121.902634
    "Santa Clara",     37.331902,     -121.899567
    

    If you do not have the coordinates yet. We also provided a simple script stopRefiner.py to use OpenStreetMap (OSM) overpass API to parse the data and generate a .csv file. Before running this script, make sure fill in line 6 in stopRefiner.py. this line require a Overpass QL request. For example node["highway"="bus_stop"](36.947831, -122.070237,37.007419, -121.916590) is request all the bus stop in Santa Cruz area. More information can be found here.

  3. Running the parser

    Make sure everything is done just simply running

    python3 GoogleStreetViewParser.py

    After the progress bar completed, all the data can be found under /downloads.

You can’t perform that action at this time.
