The attractiveness of remotely sensed data to aid in the interpretation of global and local environmental processes has been widely recognized. However, some of the most common and frustrating, yet simple, questions that are asked by potential users of remotely sensed data are what images are available, from whom, and, most importantly, how much do t h q cost? As cost is often critical in deciding whether satellite imagery is to be used in a project, it is important to determine what benefits can be obtainedfrom the use of such data. These questions are examined here in the context of obtaining remotely sensed Landsat and SPOT imagery for monitoring a spectral and spatial dynamic geological feature, namely, an active volcano, Mt Etna, Sicily.
