Abstract:
Abstract - The presented Temporal Distance Mapping tool creates a visual representation in which distance on the map represents travel time rather than physical distance. In the age of routing applications, most people are more concerned with the time it will take to reach a destination rather than its physical distance. A river, mountain, or even traffic can make nearby points on a map seem distant by comparison, while highways and fast public transportation lines can seem to bring distant physical locations together. Utilizing travel data, we can morph the shape of any mapped region to accurately depict travel time. First, a traditional static image map for a specific location of interest is overlaid with a grid of points. The travel time from the center point to each grid point is calculated. Each grid point is then shifted radially toward or away from the center point depending on calculated travel time. The rest of the map pixels are then shifted according to the new gridpoint locations using an affine transformation. In this way, the original map is warped to represent travel time relative to the center point. Although two destinations on a traditional map may have the same physical distance, the travel time may be orders of magnitude different due to barriers or access to public transportation. This map better represents access to the surrounding area, and also provides a compelling visual representation to understand the local community in the context of what matters most to them - their time.
