Mark Doherty has been with Intergraph for 20 years, and has spent a lot of time steeped in technology in general and geospatial technology in particular. This focus allowed him to give a detailed overview of where the technology of GIS has been, where it is now, and where it is going, during his keynote presentation on Thursday morning at the Rocket City Geospatial Conference in Huntsville, AL. He reviewing the history of GIS from its early mainframe days, up through the relatively near future of 3D, cloud computing, and software as a service.

Doherty's conclusion asked, where does all this leave us? "We will have a new era in computing in the maybe not too distant future." Four trends are converging to create a potentially unique opportunity: 1) SOA and standards; 2) cloud computing; 3) orchestration (e.g., taking services and chaining them together in a logical fashion); and 4) thin clients/rich Internet applications (RIA). What might these unique opportunities be? We will have to stay tuned, said Doherty.

Bob Baron, president and founder of Baron Services, gave a special presentation at the Rocket City Geospatial Conference on Thursday morning. He started by showing clips of himself and other weathermen from as early as the 1970's, which were wonderfully amusing and sometimes downright silly. He was a TV weatherman during the "grease pen on a chart" days. This experience was the impetus behind the founding of Baron Services, he explained. "In 1984, an F4 tornado came through Huntsville; there was no warning. A police officer down on the gulf coast reported that his car was overturned and that was our first warning. We lost 23 neighbors that day. We had little timely and accurate data that day - we had nice weather graphics but no weather tools. I incorporated my company two months later, and we focused on how we could do better."

Baron took the audience through the history of technology his company has developed and provided to TV stations, ending up with the company's newest product, OMNI. Baron explained OMNI: "We’re actually at the beginning of being able to show people the weather as they would actually see the weather." The company works with more than 200 TV stations around the country, so it's likely that you will see the OMNI system in the next few months.

The focus in this session was the increasing need to integrate building information models and GIS. The first speaker, Don Murray of Safe Software, talked about the need to address 3D BIM data as a new data type. "From our standpoint, BIM to GIS is just another kind of spatial data transform – [our job is to get users] to be able to move it around to where they want it – we had vector and then raster, and now we have this 3D BIM stuff," he said.

Keith Cooke of ESRI and Steve Milroy of Microsoft gave the next presentation as a tag-team. The duo discussed how ESRI's products integrate with Microsoft Virtual Earth. Essentially, you can think of ArcGIS as doing the analytical "heavy lifting" on the back end, and Virtual Earth as a 2D- and 3D-based visualization tool to help make decisions. Milroy offered the example of a plume model in downtown San Francisco.

David Kingsbury of Autodesk made some bold statements about the 3D revolution. He said, "We are right now on the verge of a whole new paradigm of using spatial data. … In the next 5-7 years, we will think of everything in a 3D context, in an object context. … It's a requirement that CAD, BIM, GIS, visualization and collaboration come together now." He also addressed how the GIS industry is relating to this change: "There's a big of a firestorm among the vendors right now rushing to [prepared for] this switch to 3D."

Three interesting speakers gave presentations during this session on Wednesday at the Rocket City Geospatial Conference. Each addressed a different topic under the loose category of spatial data management.

Joel Lawhead of NVision talked about Oracle Spatial, Oracle Locator and ESRI. NVision is a company with 44 employees that does GIS-related projects. He said, "Oracle [usage] is steadily on the rise." When the company was founded in 2002, they did no Oracle work, but now about 40% of their projects involve Oracle, and the company has hired an Oracle specialist. He described a variety of projects the company has helped with – one for the Department of the Interior's Mineral Management Service, and one for the U.S. Maritime Administration (MARAD). The last application he mentioned was one that was built just for fun – a tracking application for the TV program, "Deadliest Catch." It shows boats going out to supply the fishing boats that are trying to land that deadliest catch.

Damon Dougherty of Bentley Systems talked about the "geospatial federated approach" to spatial data management. According to Dougherty, the federated approach combines the traditional spatial search of GIS with the unstructured text search style of a search engine like Google. The example he gave was highway projects in New Hampshire. The federated search allows you to look for the GIS data as well as the graphic data and business data. As Dougherty put it, it's all about "finding information in chaos."

Bruce Westcott of Intergraph is known in the industry as being the "metadata guy." He talked about the fact that we need to move past the "withered business case" for building metadata into databases. He described that business case as one built on good will and desire to do the right thing: "You should produce metadata because other people might want to use it." That business case, for the most part, has not been successful, especially in cases where an internal mandate or business case isn't present. Westcott suggested that reexamining the legal tradition in the US of accessing government-produced data for free would be appropriate. Government entities would be given an incentive to include metadata if there was the possibility of generating revenue by providing access to the data.
