Be Inspired: Day Two
November 8th, 2011 by Susan Smith
Tuesday opened with a series of keynotes that further pushed home the message of Bentley’s direction and clarified where they were headed with GIS.
In terms of revenues for geospatial and civil, CEO Greg Bentley reiterated his thoughts of the day before, noting that government spending had some success with the Stimulus program, but now all of our governments have run out of spending consistency and there is the concern that those industries may not be sustainable.
The scale of point clouds has been such that they have been prohibitive for most companies to use effectively. Point cloud solutions have typically been tied to a hardware solution, but in the case of Pointools, it has not been tied to anything. With Pointools hardwired into both ProjectWise and AssetWise, the new services can be used to stream point clouds so that every owner operator will be able to have point clouds in their projects now.
During the years after Bentley started its own company, Bentley acquired Descartes from the Canadian company HMR. Today, Bhupinder Singh, senior vice president at Bentley, looked at the functionality in Descartes V8i that allows you to use point clouds in workflows, draping and snapping .With Descartes, it is easy to take point cloud data and create road profile or transmission lines. Point clouds can be tagged with metadata, which is done automatically but not very accurate, Descartes can reclassify them and correct them. In retrofit you can isolate, remove and combine vector based data.
What is potentially very valuable is the ability to extract analytic data from point cloud data and imagine benefits in as built drawings, for clash detecting and resolution.
Singh talked about a “Killer app” to unlock the gigabytes of data that are in point clouds and other multimedia. A new app provided in ProjectWise will help you with the big data problem. ProjectWise data transfer allows you to just send the bits you have changed so that point clouds can be streamed on demand and all that is viewed is the bits you want to view while not sacrificing any performance. Point cloud data gets accessible, and available as a fundamental data type in your workflows.
A scalable terrain model is what Singh calls “digital terrain models on steroids.” It can be built from multiple sources, and maintained easily because we maintain provenance back to the source data.
The ability in ProjectWise allows you to combine terrain models with solids and meshes and capture design intent. You can update changes as modifications are made to design.
Streamlining your GIS-based workflows
The new release of Bentley Map lets you buffer road geometry and display aerial imagery from DigitalGlobe or other web map services. This release is also a good editor of spatial databases and can combine 3D city models and allows you to work seamlessly within a federated distributed work environment.
The 3D Physical World
Greg Bentley said that “The real world is a 3D physical world.” He brought up the equation of “GIS mapping + geospatial modeling + semantic simulation”. Semantic is the study of meaning. This must have some connection with the semantic web– a manmade woven web of data that allows machines to understand the meaning of information on the web. This seems applicable to 3D
“The semantic city could be semantically connected together and would emphasize components and models and understand people’s behaviors,” said Bentley. “IBM would call it a smart city, if we would visualize this way then there are networks in a semantic city.”
Montreal is an example of a semantic city model which is maintained in Oracle Spatial 3D.
Information mobility offers opportunities to make a 3D model a semantic model and there is an opportunity for i-models to control that information mobility. “Information modeling might be what we do, but information mobility may be why we do, as to the context of our projects, and for every project it would include site conditions, weather, terrain, and continuity in design, and point clouds,” said Bentley.
