This book deals in detail about the remote sensing and geographical information
systems. Broadly speaking, remote sensing means acquiring information about a
phenomenon, object or surface while at a distance from it. This name is
attributed to recent technology in which satellites and spacecraft are used for
collecting information about the earthâÂEUR™s surface. The broad areas covered
in this book are: Aerial Photography; Basic Remote Sensing; National (Natural)
Information Managements System (NRIS); Image Interpretation; Introduction to
Digital Images; Platforms and Sensors; and Geographical Information Systems.
