Much of the more recent enthusiasm for mapping technology has been focused on consumer mapping portals for driving directions and unique visualization using satellite imagery and 3D viewing. Somewhat lost in this trend is the technological underpinnings that we seem to take for granted. Google can protest all it wants that it is not a GIS company but at the core of Google Maps is a geospatial processing system (supplied by deCarta, formerly Telcontar-also "not a GIS" system) that is interpreting and integrating location-based information. It geocodes, it integrates points, lines and areas, and displays raster imagery. Will Google Maps eventually be coupled with more advanced geographic search and query so that it looks, feels and acts like a GIS? If it walks, talks, and acts like a duck, then ArcGIS Explorer, in its beta form, already is the closest thing to "GIS on the Web." Along with Google Earth, the pair of products, and others like them, are creating a paradigm that moves the mapping industry closer to a standard way of using location technology as a platform for other business ideas and successful business models. Some companies, like Platial, use the technology solely as a platform to launch social location networking. We can expect to see other companies do likewise using the technology in applications that are yet to be defined. This paradigm shift parallels how Amazon transformed the retail sector. With all the glitz removed, Amazon is essentially a good search engine and database, fueled by effective marketing. Likewise, the next generation of these Web mapping platforms will transform a $2 billion software industry into one that could see an order of magnitude greater in revenue potential.
Data. Streets, signs, bridge heights, on ramps, restaurants, coffee shops, historical markers, my friends - my friends on the move, biohazard sensors, seismic recording geophones, tsunami warning devices, heart rate monitors (see a Garmin 301 GPS coupled with a heart monitor). We will both monitor and possibly become geo-sensors (should we choose to share our personal location data). We will broadcast geospatial data to different devices and geospatial servers that will assimilate these data to be re-broadcast to mapping portals like on-board vehicle navigation systems that might platoon your car within a traffic corridor or reroute it to compensate for network impedances. Location-based data will be more ubiquitous than they are today and we have not even begun to think of the applications that will be created.
And speaking of statistics, the mainstream media provided the most obvious data point facilitated by the long tail of mapping: one dead terrorist. The identification of the location of Abu Mousab al-Zarqawi was coordinated by SIGINT, HUMINT, and GEOINT. Signal intelligence (SIGINT) "tracked" the position of cell phone movements of al-Zarqawi's spiritual advisor; human intelligence (HUMINT) secured the location of the safe house in which he was staying; and geospatial intelligence (GEOINT) determined with pin point accuracy ground zero of the laser-guided bombs.
Looking ahead, technology and standards now being developed will begin to feed "the long tail." Web services and new options for encoding data like GeoRSS have the potential to offer unlimited access to geospatial data. A geospatial aggregator will allow users to create customized mapping applications like "my weather and traffic," "my family locator," "my competitor's sales campaigns," "my worst performing store locations from yesterday." So, let's get beyond mashups to more viable business models that have real value in the marketplace.
Watch how "consumer mapping portals" merge with "Web GIS" very soon. The long tail of mapping is, right now, very short but it is "growing legs" and will have incredible reach.
