Visualizing Data with Street Map Service in JMP®
John Ponte, SAS
Adding a background map to your visualization is an effective way to add context to your data, particularly when the data is geographical. But the background map options in JMP prior to version 11 did not allow you to zoom in on a local region such as a city. With the addition of the Street Map Service in JMP 11, you can now drill down on your data to see details at the street level. The Street Map Service is the newest option on the Background Map dialog. Like some of the other mapping options in JMP, it requires an Internet connection and accesses a server for up-to-date maps. JMP provides the Street Map Service so that the availability of the server is reliable. The server generates maps on demand using OpenStreetMap technology and data. The amount of detail in a map is determined by the size of the map and the zoom level. Zoomed out, the map shows country and state names with major highways. The detail in the map increases as you zoom in, revealing minor roads, street names and building footprints. Maps are generated using a soft color scheme to enable your data to stand out. This poster demonstrates how you can display crime data for a city. You can get an overview of the data across the entire city and then zoom in to a particular neighborhood or street. Each bubble represents a reported crime, with the location of the bubble indicating where the crime took place. Bubbles are color-coded by the type of crime, as indicated by the legend. The northeast region of the city shows a concentration of crime activity. By zooming in on the data, you can distinguish and identify individual bubbles.
