13. Integrative Sensing

An exercise in remote sensing commonly results in the production of a thematic map that depicts characteristics of the land surface germane to the motivating application. The cartographic convention of the map effectively communicates information that documents the spatial disposition of the desired elements, landscape elements and aids decision making as the patterns revealed on the map are interpreted and appraised. However, the outcome of a remote sensing investigation also serves as data for additional analytical treatment and wider forms of inquiry. When working in concern with complimentary geospatial technologies, remote sensing embodies a core methodology within the expanding field of geoinformatics; a discipline which integrates the acquisition, modeling, analysis, and management of spatially referenced data. Understanding remote sensing’s contribution to this larger endeavor not only strengthens its role as an information technology, but further demonstrates the uniqueness of the remote sensing solution. As innovation continues to propel geospatial technologies forward, integrative sensing with remote sensing as the center-piece can be anticipated. Realizing this future depends on how and when remote sensing can be marshaled to support extended geomatic studies and where an appropriate technological fit can be achieved. In this chapter, we will examine the concept of integrative sensing. From this discussion we can explore the connection between geo-imaging as realized via satellite remote sensing and the field of geoinformatics as evidenced in the defining technologies of geographical information systems (GIS), environmental sensor networks, and geosimulation.
