PEMS Demonstrator Project

Client: Cooperative Research Centre for Spatial Information.

The term ‘PEMS’ stands for Platform for Environmental Modelling Support.  PEMS is a data platform that adopts a grid cell (also called raster) based approach to managing spatial information (SI).  The basic objective of PEMS is to provide a platform which supports the SI needs of modellers and decisions support systems.  Once established, the same platform can also support simple spatial queries and analyses to spatially enable professionals, with little or no SI knowledge, to a point where they can build SI into their processes in a simple and repeatable manner.

To achieve this PEMS aims to develop a shared infrastructure that provides an economic and effective means to integrate SI from a variety of sources, and in various formats, to support commonly required query, analytical and modelling tasks.   This will be based on a set of standard grids and projections to support new and existing business activities.  The goal is for production systems based on PEMS across Australia to be developed as an integral part of the Australian Spatial Data Infrastructure, providing easy access to current and authoritative grid cell-based data.

To promote the PEMS ideal to key users and stakeholders in Australia, the Cooperative Research Centre for Spatial Information (CRCSI) has funded the development of PEMS as a Demonstrator.

The purpose is to develop typical functions of PEMS and showcase to interested parties the core technical components and user interactions experience that exemplify the full PEMS Production system.  The Demonstrator aims to form the reasoning for the larger scale development of PEMS through an evaluation strategy involving a host of partners including the Victorian Departments of Sustainability and Environment, Justice, and Primary Industries; Geoscience Australia and Spatial Vision.

A formal evaluation on the PEMS Demonstrator application will be undertaken to assess core technical components of the Demonstrator and user interaction experience, and evaluate if the Demonstrator establishes the case for the larger scale development.

In evaluation of the PEMS Demonstrator application is scheduled for completion in June 2008.  Spatial Vision* is responsible for the development of the PEMS Demonstrator system. DSE is managing the project on behalf of the CRCSI. Other project participants are supporting the project by contributing specific modelling expertise and experience.

*Spatial Vision is a member of 43 Pty Ltd, the company formed to manage SME interaction with the CRCSI (see www.crcsi.com.au for further information).
