Low-cost remote sensing experiments within an educational environment

摘要

The results of a two-year preliminary investigation into the remote sensing field are described. Ways of investigating some of the major disciplines involved at low cost are shown. In particular a means of combining disciplines to yield topical experiments at graduate level is shown. Some of the many research possibilities within the field are also indicated. Based on experiments with data from a Nimbus-7 coastal zone colour scanner, multiband aerial photographs and an experimental low-cost image processor, an introduction is given to such aspects as atmospheric correction, data sources, typs of classification, fundamental hardware requirements and related image enhancement software.
