A photograph refers specifically to images that have been detected as well as recorded on photographic film. Remote sensing useful for Mapping rock units (stratigraphy). Noise in an image may be due to irregularities or errors that occur in the sensor response and/or data recording and transmission Common forms of noise include systematic stripingor banding anddropped lines Striping was common in early Landsat MSS data due to variations and drift in the response over time of the six MSS detectors For a treatment of remote sensing at microwave wavelengths see J. Photographic film has the clear advantage of recording extremely fine spatial detail, since individual silver halide molecules can record light sensitivity differently than their neighbouring molecules. x}}mGuCjRU{y{>/ 6`>!~$y6&*%@V4uBR" `4R)%Em? relate image data to quantitative ground measurements (e.g., vegetation characteristics like LAI and biomass, and water quality data).

Before we go on to the next chapter, which looks in more detail at sensors and their characteristics, we need to define and understand a few fundamental terms and concepts associated with remote sensing images. Energy Source or Illumination (A) 2. Possibly the most significant characteristic of the image data provided by a remote sensing system is the wavelength, or range of wavelengths, used in the image acquisition process. It is important to distinguish between the terms images and photographs in remote sensing. Institution of Surveyors (Australia) Annual Congress, Alice Springs.

What is remote sensing Remote Sensing: remote sensing is science of - acquiring, - processing, and - interpreting images and related data that are obtained from ground-based, air-or space-borne instruments that record theinteraction between matter (target) and electromagneticradiation. However, in the near-infrared, although both types reflect a significant portion of the incident radiation, they are clearly separable. What would be the advantage of displaying various wavelength ranges, or channels, in combination as colour images as opposed to examining each of the images individually? Hoffer, 1978: Biological and Physical Considerations in Applying Computer-Aided Analysis Techniques to Remote Sensor Data. remote sensing is detecting and measuring of electromagnetic energy (usually photons) emanating from distant objects made of various materials, so that we can identify and categorize these object by class or type, substance, and spatial distribution image classification has the overall objective to automatically categorize all pixels in an image 5 in P.
