Definition
Environmental phenomena that vary continuously across regions of space and periods of time, such as changing sea temperature, concentrations of gas pollutant in the air, or levels of soil moisture, are called dynamic spatial fields. Information about dynamic spatial fields is important to a wide range of environmental applications. One of the goals of using a geosensor network (GSN) is to enable improved, more detailed monitoring of dynamic spatial fields. Individual sensor nodes in a GSN usually generate quantitative information. For example, a node might record a temperature of 23 ∘C located at coordinates 18.04S, 146.49E at time 20:51:06 on January 7th 2007. However, the information needed by decision makers is typically qualitative, and concerns the relationships between groups of spatially and temporally...
