Abstract

Web-Based GPS Processing and Travel Pattern Visualization
Track: Analysis
Authors: Dara Seidl

In 2012, Abt SRBI unveiled an ESRI-based GPS processing system that delineates precise trip origins and destinations from continuous streams of raw GPS data. Abt SRBI now takes this technology to the web with online processing and reporting tools. Team members have built a web application using ArcGIS Server and APIs to process and visualize travel data obtained from GPS devices. Since location-based data are extremely sensitive to privacy concerns, strong aggregation and data protection techniques have been implemented to safeguard identities. The online GPS visualization enhances project reporting and dissemination of findings from GPS-based travel surveys. This presentation highlights some of the techniques used to achieve successful processing and reporting of these massive quantities of data.
