Remote sensing and geographic information systems - C. A Legg

This study opens with a look at the significance of remote sensing and geographic information systems in the mineral industry before moving on to briefly outline the basic concepts of remote sensing. The author defines the role of geographic information systems (GIS), examining the synergistic importance of data integration. Also covered are raster and vector based systems and problems of data input. Examples of hardware and software are given and some case histories reviewed. There is comprehensive coverage of current spaceborne and airborne systems and a review of systems that are still under development. This section of the book closes with a discussion on what criteria to consider in choosing the right system for the job.;The use of remote sensing and geographical information systems in mineral exploration is explored. The author covers the historical background, including the use of early Landsat MSS, and discusses how the increasing use of computerization has led to greater acceptance of GIS concepts.;One neglected field in remote sensing, where an important and cost-effective contribution can be made, is mine planning. This issue, together with a discussion of how remote sensing can help in various ways with the environment (including mapping existing land use, analyzing proximity to sensitive areas, perspective modelling and modelling land use changes) leads into a review of the use of remote sensing in water supply and land restoration.;The importance of remote sensing as a tool in the mining industry is emphasized throughout, with appropriate levels of technology being demonstrated for various applications. The author points out the growing importance of remote sensing to an environmentally, and increasingly cost conscious, mineral industry.
