This blog is dedicated to the topic of integrating CAD and GIS and the issues of being able to combine these two types of technologies. But rather than look at CAD and GIS as technologies consider the data that they represent. CAD information typically represents small scale precise engineering projects describing 'a conceptual design', or 'what is built or in operation' and GIS information typically represents larger scale representations of phenomenon including the natural environment. Perhaps the perfect union of these two types of information can best be seen in the context of a city, where ideally the balance of the human built environment and our necessary infrastructure meets the esthetics and preservation of 'green space'.
Recently, Autodesk has released a technology preview called Galileo which aims at being an easy-to-use planning tool for creating 3D city models from civil, geospatial and building data, and 3D models. In addition, recent developments in the geospatial community have started to look at the need for geodesign. This is simply CAD and GIS integration that allows for iterative design sketches to be vetted out based on geospatial information. Project Galileo can act as a hub for design and geospatial information to be integrated, as well as allowing for some light weight urban design sketches (roads, water, buildings) allowing for geodesign to occur. To see how the project is being developed you can view a recent presentation given at the geodesign summit by Chris Andrews (Project Manager - Autodesk).
