Some time ago I wrote about the impending Carbon Pollution Reduction Scheme (CPRS) in Australia and its potential opportunities for the spatial industries. The CPRS was the brainchild of then Prime Minister, Kevin Rudd, who was subsequently unceremoniously dumped. With the Greens now in control, the pressure is on to have a carbon price.

One of the most powerful tools in the analytics toolkit for decision making is the development of mathematical models, also known as mathematical programming (MP). Mathematical programming encompasses a wide-range of techniques including linear programming (LP), dynamic programming (DP), simulation and others. In most applications of mathematical programming models, there is an overriding objective that

Real time, full-scale analysis immediately and positively impacts all stakeholders in slightly different ways. Architects and engineers rush to validate their designs naturally looking for opportunities to improve their product. Owners experience a sense of relief and tend to take immediate ownership of their prior decisions and look forward to future input and final product

We are witnessing what may be one of the worst man-made environmental disasters of all time. As devastating as Chernobyl and even more catastrophic than the Exxon Valdez, the Deepwater Horizon disaster in the Gulf of Mexico increasingly appears to be the result of deliberate decisions to cut cost, and save time.

Today, GIS is becoming more part of business processes, and the consequence of this change is that there are many more users with much higher requirements regarding the availability of GIS services. This column describes the path from a workgroup to an enterprise GIS.

Earlier in the month I was asked to present at the British Cartographic Society conference on the issues of accurately representing “place” in a 3D model. The concept of ‘place’ (as opposed to simply ‘location’) has been gaining prominence in recent years, with the Association for Geographic Information (AGI) 2009 conference focusing on place as
