The spectral reflectance curves for vigorous vegetation manifests the "Peak-and-valley" configuration. Soil effects: Soils tend to darken when wet, so that their reflectance is a direct function of water content. Vegetation: The reflectance received in t he r an g e f r om about 0.7 t o 1.3 μm from vegetation and it reflects t y p i c al l y 40 - 50% of the ene r gy i nc i de n t upon it. The USGS Spectral Library contains reflectance spectra, including samples of minerals, rocks, soils, physically constructed as well as mathematically computed mixtures, plants, vegetation communities, microorganisms, and man-made materials. Spectral reflectance curve of dead stressed vegetation 1. Spectral Reflectance *The reflectance characteristics of Earth’s surface features may be quantified by measuring the portion of incident energy that is reflected. The VIs are used to analyze various ecologies. Spectral Reflectance of Vegetation The spectral characteristics of vegetation vary with wavelength. A typical spectral reflectance curve of the most common earth surface materials viz., water and vegetation is shown in Fig 1. SR = R NIR / R R 17 Optical Properties Vegetation reflectance properties are used to derive vegetation indices (VIs). VIs are constructed from reflectance measurements in two or more wavelengths to analyze specific characteristics of vegetation, such as total leaf area and water content. The internal structure of healthy leaves act as diffuse reflector of … Typical Spectral Reflectance Curve of Soil, Water and Vegetation. To detect healthy vegetation using this band combination is easy because the spectral reflectance curve of a healthy green vegetation has a significant low reflectance in the electromagnetic spectrum visible portion which comes from the plants leaves pigments. Spectral reflectance characteristics of vegetation 63 2.2 Photoelectric elements 2.2a Reflectance spectrophotometers: These instruments measure the hemispherical reflectance of sample stick on a window of a sphere and lighted by an artificial source of radiation. 1.8 shows the average spectral reflectance curves for three typical earth's features: vegetation, soil and water. Spectral Reflectance Curve of Dead/Stressed Vegetation 2. A compound in leaves called chlorophyll strongly absorbs radiation in the red and blue wavelengths but reflect green wavelength. Vegetation typically absorbs in the red and blue wavelengths, reflects in the green wavelength, strongly reflects in the near infrared (NIR) wavelength, and displays strong absorption features in wavelengths where atmospheric water is present. The Reflectance … Spectral Reflectance Curves for Natural Grass and Artificial Turf Visible versus Infrared Photos Visible Portion (Panchromatic) Near Infrared Football field has Artificial Turf Typical Spectral Reflectance curves for Vegetation, Soil and Water Lines in the figure represent average reflectance curves VEGETATION (Healthy Green Vegetation) Spectral reflectance of common land covers Vegetation has a unique spectral signature which enables it to be distinguished readily from other types of land cover in an optical/near-infrared image. The reflectance of vegetation in the SWIR region (e.g. Water has strong absorption bands around 1.45, 1.95 and 2.50 µm. Every object on the surface of the earth has its unique spectral reflectance.Fig. band 5 of Landsat TM and band 4 of SPOT 4 sensors) is more varied, depending on the types of plants and the plant's water content. The reflectance from vegetation depends upon internal structure of leaf and condition of plant. If the spectral response to moistening is not exactly the same in the two spectral bands, the NDVI of an area can appear to change as a result of soil moisture changes (precipitation or evaporation) and not because of vegetation changes.
