Working on both the AIDSVu and medical society projects for my job, I’ve had the opportunity to scratch the surface of location-based technologies.
For AIDSVu, we built a locator for STD testing centers around the US. Using your IP coordinates as a starting point, the site looks up the nearest testing centers to you. If the IP coordinates aren’t right (which they likely won’t be, as they map to the ISP location), you can enter an address which is geo-coded using the Google Maps API. This was an impressive feature for our clients as it provided immediate value to their customers and users. It promoted content in a way that’s more personal, a continual goal of information technology.
With the medical society software, the locator is built to let patients search for physicians by term and location (e.g. Cardiologists in San Diego). The former isn’t that exciting–keyword-based search is as old as the Internet (not really, but it’s old). Combining keyword with location-based search, though, is new. For someone with a medical condition that needs the nearest help they can get, being able to find the closest doctor who specializes in treating their symptoms could be both a time and life saver.
Implementing both of these features was a blast. The GIS (Geospatial Information Systems) world is fun, complex, and deep. After a year dabbling in parsing geographic datasets, map plotting, data mash-ups and geo-coding, I’ve barely scratched the surface. But there’s a mountain of potential here and it’s progressively catching on.
With the emergence of mobile phones as replacements for computers when accessing information, the potential of GIS to change how we interact with the world around us is huge. Wherever you are, the phone knows your geospatial location. It can transmit that data to an endless supply of web services which return location-sensitive data, providing a new layer of interactivity to life.
Imagine this: you’re a bicyclist in a busy city. Part of every day involves subconsciously calculating the risk of an accident as you speed down the road alongside cars, trucks and public transportation. In your back pocket is your cellphone. As you roll along, your phone is using your location to query the city’s crime lookup service, searching for bike accident reports in your vicinity. As you near a particularly hazardous intersection, the phone begins vibrating in pulsations, warning you of the risk ahead. In this application, it could save your life. In others, it can simply, but powerfully, add a new dimension to how we process and apply the myriad information we consume daily.
Our primary challenge each day is to make the best decisions we can with limited information. But there’s far more information available to help us make decisions than we concurrently have access to. The issue is that it’s not easily accessible in a way that’s helpful to us right here, right now, wherever that may be. With the world of mobile computing on the rise, we’ll see more and more applications that mash-up data in ways that offer the chance to improve the quality of our decisions. This has monumental implications.
It’s going to be an exciting decade and beyond.
