Simard Canada Centre for Remote Sensing 588 Booth Street Ottawa Ontario Canada K1A 0Y7 ABSTRACT This paper describes initial steps toward building an integrated earth sensing capability that encompasses both remote and in-situ sensing. Initial work has focused on the demonstration of in-situ sensorweb prototypes in autonomous remote operation in the context of monitoring applications in Earth and environmental science. The paper discusses integrated Earth sensing and sensorwebs and reports on an in-situ sensorweb prototype demonstration in support of flood hazard monitoring in Manitoba as well as on development plans for a more advanced heterogeneous sensorweb in support of drought severity and rangeland crop vigour monitoring in Alberta. 1. INTRODUCTION INTEGRATED EARTH SENSING AND SENSORWEBS Our monitoring requirements and responsibilities as nations and as members of the global community continue to multiply. We have some powerful science and technology tools at our disposal but it is not clear that we are using them effectively to tackle the issues before us. In many countries government agencies in particular have long traditions of excellence in field data acquisition and more recently space-based observations of the Earth. However such endeavours have been and largely remain resource-intensive activities. Innovative tools need to be developed to provide the time-critical and cost-effective monitoring of complex and dynamic systems essential to support effective decision-making. At the 2002 World Summit on Sustainable Development the point was made that . space-derived information generally needs to be combined with insitu measurements and models to obtain a holistic picture of the Earth s .
