Discussion:
The map is constructed using two underlying datasets - spatial events and traversable roads. The paths can be queried either using shortest path, a user-defined path, or a radial path where a user is shown all the possible traversable locations within a particular radius. The rendering of paths is dependent on the spatial characteristics of the path segments, i.e in this case, spatial regions are characterized by the number of crimes recorded. The user also has the power to create visualization summaries by sketching out regions on the map
Godwin, Alex, and John Stasko. "Drawing Data on Maps: Sketch-Based Spatiotemporal Visualization."
Summary:
This paper is a joint effort by GeorgiaTech and the Atlanta Police Department, to help create visualization tools for understanding crime patterns, based on the user interaction with a map surface. The system allows sketching of 3 types of paths - shortest path, user defined path and radial path. The main purpose of this paper is to present a technique of visualization aid using map sketching. There is little or no recognition component used here.
