Example: satellite remote sensing images show cyanobacteria outbreaks We will first look at the mechanism of remote sensing monitoring of blue-green algae outbreaks. When blue-green algae bloom, green algae mixed with white foam pollutants on the surface of water. The spectral characteristics of blue-green algae cover area are obviously different from those of the surrounding lake. Because of the high chlorophyll A content, the blue-green algae region has a higher reflectivity in the LandsatTM2 band and a slightly lower reflectivity in the TM3 band, but still higher than the lake water, and the maximum reflectivity in the TM4 band. Thus, in TM4 (red), 3 (green) and 2 (blue) pseudo color synthesis Image, a crimson and blue, dark blue, blue and black around the lake has the obvious difference. In addition, the outbreak of blue-green algae is affected by the lake flow and wind direction, extending along the strip, showing a banded structure and flocculent texture on the TM image, which is obviously different from the surrounding lake and water surface. 451: the most abundant combination of information, TM images of light wave information has 3~4 dimensional structure, its physical meaning equivalent to brightness, greenness, heat and humidity. In the TM7 band spectral images, the fifth bands usually contain the most abundant object information. The correlation between the 3 visible bands (i.e., the first, second, third bands) and the two mid infrared bands (i.e., the fourth, seventh bands) is very high, indicating that there is considerable repetition or redundancy in the information of these bands. The fourth, sixth band is special, especially the correlation between the fourth band and other bands is very low, which shows that the band information is very independent. The calculation of various combinations indicate that color images by a visible and middle infrared bands and band 4 and generally has the most ground information, which are 4, 5, 3 or 4, 5, 1 for the best band combinations. The seventh wave band has special function only in detecting forest fire, rock ore alteration zone and clay mineral type of soil. When the best band combination is selected, the color rendering problem must be considered in order to obtain the best color composite image. The most sensitive color of the human eye is green, followed by red and blue. Therefore, the maximum variance bands should be given to the green. According to this principle, take 4, 5, 3 respectively. The band red, green and blue Fu image synthesis, color contrast, rich layers, and various types of color display rules similar to the conventional synthesis, consistent with past conventional visual interpretation of habit. For example, 4, 5, two bands of color transfer, that is, 5, 4, 3, respectively, given red, green, blue, and then access to approximate natural color composite images, suitable for non remote sensing application professionals. 741: band combination images have the advantages of compatible infrared, near infrared and visible band information, and are rich in color and level Good sense, it has abundant geological information and environmental information; and high definition, less interference information, geological interpretation of a high degree of various structural features (folds and faults) showed clear boundary, different types of rocks Clearly, the boundaries of lithostratigraphic units, the distribution of special lithologies, and the volcanic mechanism are also clear. In 742:1992, the comprehensive interpretation of the gold and silver ore deposits in Southeast Guangxi was carried out by remote sensing geological interpretation. By using 1:10, 000, TM7, 4 and 2 false color synthetic plates to interpret, 1615 linear structures and 481 annular images were interpreted, On the basis of summarizing the characteristics of remote sensing images and metallogenic models of tectonic altered rock type, quartz vein type and volcanic rock type typical ore deposit, the metallogenic prognosis of the whole basin is delineated, and 2 types of gold and silver a type metallogenic prospect areas are delineated. B 4, C class 5. The remote sensing evidence is provided for the optimized target area in this area. 743: our country has successfully monitored the forest fire and post disaster changes in Greater Khingan Range by using Landsat imagery. This is because the TM7 band (2.08-2.35 microns) sensitive to temperature changes; TM4 and TM3 band respectively belong to infrared light, red light district, the best band can reflect the vegetation, and reduce smoke influence function; at the same time, TM7 TM4, TM3 (red, green and blue respectively given) color composite colors close to nature color, it can be through the analysis of the TM743 color composite image to command and control the spread of forest fires and disaster recovery in the forest. 754: the change of water level in different periods of the lake, also can use different bands, such as the use of Landsat MSS7, MSS5, MSS4 synthesis and standard false color images in blue, dark blue color to distinguish different levels. Therefore, it can be used to analyze the geographical law of lake water level change. The remote sensing investigation of sand and gravel mine in 541:XX development zone is made by choosing the best combination of fefee7 bands for Landsat TM (TM5, TM4), (TM1) as well as interpretation and analysis of various remote sensing data of Aeronautics and Astronautics, preliminary interpretation is made to ascertain the Quaternary geomorphology in the surveyed area. For example, 4, 5, two bands of color transfer, that is, 5, 4, 3, respectively, given red, green, blue, and then access to approximate natural color composite images, suitable for non remote sensing application professionals. 543: band selection and principal component analysis Our study uses the August 2, 1995 TM data. Analysis on the screen and the screen image, the amount of information is most abundant in 5, 4 and 3 bands with red, green and blue three colors to generate false color composite image, image synthesis of this combination is not only similar to natural color, a symbol of people's visual habits, but also due to the abundant information, can fully display the imaging features of various features of the difference, to select the training site, can ensure the accuracy of the training ground; for computer automatic recognition, using principal component analysis (K-L transform) data compression, the formation of the image data of the three components, used for automatic recognition. The work is based on the interpretation of remote sensing images, combined with geological, geophysical and geochemical data research methods. Interpreted as visual interpretation, Interpretation of remote sensing images: in March 1984 imaging, processing, amplification of 1:5 million satellite TM false color film (5) (4, 3 band synthesis) and July 1979 shooting of 1:1.6 million black and white aerial film as the main working species; used in November 1986 1:10 million TM false color film (7, 4, 2 band synthesis) as a reference species. 453: the research of remote sensing information source is the satellite remote sensing receiving station Chinese Academy of Sciences in October 1995 the United States to receive MSS satellite remote sensing TM band 4 (red), band 5 (green), band 3 (blue) CCT tape data produced by the 1: 100 thousand and 1: 5 Million false color composite satellite image. The image features of Karst landform landscape and land use are distinct in mountain, hill, plain and tableland. During the imaging period, late rice was close to harvest, and no water was accumulated in the paddy field, so the cultivated land types The color of the paddy fields is pink; the dry land is grey because the crops are mostly harvested and the soil is less water; the vegetable fields are bright and scarlet because of the good growth of vegetables. The color of the garden is light brown and the plots are in regular order, Clear outline. The forest trees in the woodland were dark brown, while those in Karst, mountains, hills and other areas were yellow to brown. Most of the pasture lands are yellow green. The towns in the construction land were blue and the highway was linear, Gray tone; railway like the line, color is light blue; the runway as the blue line, blue and green grass background; in the construction of the new airport construction site for the white rectangle; the old airport to spare white hue, the contour is clear, Rule. The reservoirs and rivers are dark blue. Take 4, 5, 3 respectively. The band red, green and blue Fu image synthesis, color contrast, rich layers, and various types of color display rules similar to the conventional synthesis, consistent with past conventional visual interpretation of habit. 472: in the use of TM4, 7, 2 band false color synthesis and 1:4 computer interpolation magnification technology, in the production of 1:5 million TM image, and 1:5 million engineering geological map, the quantitative monitoring of the development rate of the collapse of the shore, as well as in a single aerial film to calculate rock (broken) Layer, production, and other aspects are unique. Three. Type extraction: 1. extraction of cities and towns: TM1+TM7+TM3+TM5+TM6+TM2-TM4 2. towns and villages: TM1+TM2+TM3+TM6+TM7-TM4-TM5 3. extraction of rivers: TM5+TM6+TM7-TM1-TM2-TM4 4. Road: TM6 extraction (TM1TM2TM3TM4TM5TM7) Four. Spectral differences TM1 residential areas are not easy to separate from rivers and vegetable fields TM2 residential areas are not easy to separate from rivers and vegetable fields TM3 the country is not easy to separate from the vegetable garden TM4 farmland and roads are difficult to divide, and towns, roads and beaches are easy to muddy TM5 county is not easy to divide with farmland TM6 villages are mixed with rivers First of all, to understand the difference between pseudo color images and other images, usually in RS, single band or panchromatic band is shown as black and white images, and the quality of black and white images is usually measured by gray scale. The three band combination is represented by color images, including: True color (true Color (three): band combination), respectively, on the RGB image of three bands with RGB three colors correspond to actual color image and the original color consistent area or scene synthesis, called true color, is the only true color synthesis. Pseudo color (pseudo) Color): black and white image transform for color image of different gray or gray range according to the value given a different color or a color series, color and actual color image is not consistent, namely pseudo color image. False color (false) Color (three): band combinations to get different bands), were given three yuan color image RGB, not with the original band RGB three bands corresponding to color and actual color images are inconsistent, known as the false color image, false color image is characteristic in order to make some things more obvious and help us to interpret and analyze. The ETM+ image is used as an example to discuss the main applications of false color images TM the technical parameters of each band are shown in the following table, Different combinations of any three bands (with the exception of 321 combinations) form different false color forms and different applications: Reading (596) | comments (0) | cool (0) | of | share | report | classification: GIS&RS Previous: Landsat TM band portfolio next: digital model common software Zero Cool point Only login users can send cool points, please login first. - Blog comment No comment for the moment.
