Functions of a MSDS Scanner

A Multispectral Scanner and Data System refers to a remote-sensing instrument used in earth resources survey programs. Modern multispectral scanners are more advanced with features enabling real-time high resolution imaging systems. These advanced scanners record images of earth resources at high spatial resolution. The advanced features of a MSDS scanner make it suitable for tasks such as strategic intelligence, geologic mapping, oil spill detection, forest inventory, water chlorophyll studies and fire mapping.

  1. Collecting Information on Earth Terrain

    • A multispectral scanner collects spectral and spatial information on earth terrain scanned above the surface. Multispectral scanners are usually mounted on survey aircraft to record earth resources. Features inherent in a multispectral scanner enable viewing of many wavelengths simultaneously. Spectral bands are recorded by detector arrays in a focal plane of grating spectrometers. The radiometrically calibrated bands using field-filling sources can be viewed during the inactive period of a scan cycle.

    Geologic Mapping

    • MSDS scanners are useful in geologic mapping. By use of specialized scanner software aboard survey aircraft they measure and geocode each image pixel to map coordinates. These help in producing imagery compatible with geographical information sensing. When survey aircrafts touch down, corrected imagery is produced while raw data is recorded.

    Strategic Intelligence

    • In addition to geologic mapping, MSDS scanners are useful alongside intelligence equipment in providing real-time satellite imagery links to a designated workstation. Information produced through such links is then superimposed over a standard base map to decipher useful intelligence information. Strategic intelligence functions facilitated by MSDS scanners cut across a variety of uses.

    Natural Resource Inventory

    • MSDS scanners are useful tools in keeping track of global forest inventory. They are useful in forest inventory by providing real-time imagery on forest degradation, forest cover distribution and real-time environmental studies. These include water pollution, chlorophyll conditions and waste settling in water resources. These can be easily monitored using the built-in remote sensing technology in MSDS scanners.

    Pilferage Detections

    • MSDS scanners are used to detect oil and gas pilferage. A configured multispectral scanner when mounted on a distribution pipeline helps in leak detection during transmission and distribution. This is a significant step in curbing losses arising from fuel pilferage as well as facilitating better fuel management systems. The built-in sensors and optical instruments help in providing real-time images of pilferage points.
