Summary

The goal of this chapter is to discuss the issues associated with managing remotely sensed image data with a particular focus on the problems unique to such data, and to provide a few examples of how some existing systems handle those problems. Section 3.2 gives a brief history of remote sensing. Section 3.3 provides a discussion of applications with two examples of assessing human impact on the Earth's environment. Section 3.4 covers data collection systems briefly with emphasis on defining terminology relevant to obtaining and managing image data. Section 3.5 is a discussion of the types of errors and artifacts in remotely sensed images and the corrections required before proceeding with higher levels of information extraction. Section 3.6 outlines processing steps to derive useful information from remotely sensed images. Section 3.7 addresses the implications of the variety of collection systems, processing, and usage patterns on the storage and access of remotely sensed image data. Section 3.8 gives a few examples of systems managing such data and how they address the issues identified in Section 3.7. Section 3.9 concludes the chapter with a summary of the key points.
