"Work" will provide geo-coordinate data to supplement data provided by Hawaii Open Data for Traffic Incidents, adding the capability to plot map locations. Data will be stored in a separate database to be utilized by mid and front end developers.

Team Members:

A = Andrew

B = Joanne

Work Modules:

1. [A] getIncidentData - retrieve JSON data from Traffic API

2. [J] processAddress - prepare valid address

3. [J] getGeoCodes - provide valid address to Geo Code API to retrieve geo coordinates (lat=latitude, lng=longitude)

4. [A] storeIncidents - insert incidents with valid geo coordinates to PostgreSQL database

API Data:

incident_number, date, code, type, address, location, area
