Remote sensing are available in most remote sensing textbooks, including those by avery and berlin (1992), szekielda (1988), elachi (1987), sabins (1987), and swain and davis (1978). Most satellite sensors detect emr electronically as a continuous stream of digital data. The data are transmitted to ground reception stations, processed to create defined data products, and made available for sale to users on a variety of digital data media. Once purchased, the digital image data are readily amenable to quantitative analysis using computer-implemented digital image processing techniques. Sabins (1987) describes these techniques in the chapter. Remote sensing: principles and interpretation. Some of these techniques (such as data error compensations, atmospheric corrections, calibration, and map registration) essentially involve preprocessing the data for subsequent interpretation and analysis. Another group of techniques is designed to selectively enhance the digital data and produce hard-copy image formats for interpreters to study. For these images, some of the principles and techniques of airphoto interpretation can be applied to manual analysis of the image information content.
ReplyDeleteRemote sensing are effective tools to generate accurate data for gis applications. Aerial photogrammetry is mainly used to produce topographical or thematic maps and digital terrain models. Map tell remote sensing division is capable of interpreting and incorporating remote sensing data into raster and vector gis formats. We help you to implement state-of-the-art web mapping applications. We use different gis and internet map server tools for application development. We have extensive experience in developing lbs/avl applications using open source map servers and viewers.
