(1994) provide a useful discussion on the different algorithms submitted for the PIP-1 exercise, noting three main groups of algorithms: Watch it on YouTube. Remote sensing systems which measure energy that is naturally available are called passive sensors. 10. Sure, the advantages are: 1. Active sensors emit energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target. The user stands to lose a lot of information due to the generalization of data. channels enable remote sensing of different parts of the atmosphere Radiometric Resolution: Remote sensing measurements represented as a series of digital numbers – the larger this number, the higher the radiometric resolution, and the sharper the imagery Spectral Bands and Resolution for various sensors cimss.ssec.wisc.edu 25 The sun's energy is either reflected, as it is for visible wavelengths, or absorbed and then re-emitted, as it is for thermal infrared wavelengths. Better resolution (wavelength is much higher and thus with the right signal equipment you would get more signal bandwidth). There are two types of remote sensing technology, active and passive remote sensing.. This section will try to evaluate some of the advantages and related disadvantages of the statistical–empirical techniques over other current passive microwave algorithms. Wilheit et al. Microwave remote sensing instruments acquire data useful for geophysical investigations by measuring signals arising due to interaction of microwaves with natural media. Generalization may lead to loss of important information: In performing data analysis using a GIS system, there is a lot of generalization due to the massive data being analyzed. Large amounts of data: A GIS system stores extremely large amounts of data at any given time. Advantages of WSN are multishop networking, in-network processing, technology can deploy different network topologies, communication is secured among nodes and ability for long reading ranges. The sun provides a very convenient source of energy for remote sensing. 9. The main advantages of microwave remote sensing are due to its ability to 2.
