GIS -- where Esri is probably the most prominent data provider -- is related to ITS by way of providing ITS research with road maps. Traditionally, GIS data come as .shp files in 2d- or 3dmesh format. The sad news is that (1) even 3dmesh is low resolution, and (2) native GIS roads maps have no context. This study presents a web application which extracts pairwise routes via Google Maps API and stores them in cloud storage (Google Drive, Dropbox, etc.). When done, pairwise routes are merged into the graph ready to use for ITS simulations. The webapp is socially scalable and can use any number of clients, which is important for large datasets.
