Abstract: Soundscore™ is HowLoud, Inc.’s patent-pending technology to build our noise map and deliver data to users. A Soundscore™ rating is a number between 50 (very loud) and 100 (very quiet) that tells you how loud a location is due to environmental noise.

ETL for us_soundscore_howloud

######### # GDSC ETL is performed in two steps: shell script to ETL data into postgres # and then additional transformations with SQL in postGIS (if needed). #### ######### # Step 1 - bash script (pseudo code) #### # create directory structure and move into it mkdir -p /data/us_soundscore_howloud/{download,etl} && cd /data/us_soundscore_howloud # set update flag based on last update and update frequency do_update=0 if date() < last_update + update_frequency else do_update = 1 #
