Remote sensing of vegetation is a useful tool for many applications in ecology, agriculture and beyond. This short tutorial showing you how to calculate the soil adjusted vegetation index - and alternative to NDVI which aims to better account for the influence of soil reflectance - using freely available Sentinel-2 satellite imagery in QGIS 3.

The NDVI (Normalized Difference Vegetation Index) is a versatile vegetation index to evaluate the vegetation and dynamic of the vegetation coverage change. This index has been studied and evaluated with many satellites over the years, changing its calculus method in relation to the number and type of bands of the satellite. This video shows how to apply the NDVI to Landsat-8 images using QGIS 3.4 (aka Madeira) Landsat-8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9. The ultra blue Band 1 is useful for coastal and aerosol studies. Band 9 is useful for cirrus cloud detection. The resolution for Band 8 (panchromatic) is 15 meters. Thermal bands 10 and 11 are useful in providing more accurate surface temperatures and are collected at 100 meters.

#Subscribe #SeekShow #ArcGiS Deriving temperature from Landsat 8 thermal bands / Estimating Land surface Temperature using arcmap * check below description for 6 equations you can apply on raster calculator tool This is how to calculate LST ( Land Surface Temperature ) using Land-Sat 8 bands. Here i have used Band 10 as a thermal band, and band 4 and band 5 to calculate the NDVI ( Normal Difference Vegetation Index ) To calculate the LST - USGS formulas have been applied on arcmap raster calculator tool which is the only tool used to calculate the LST -Used Equations - 1) TOA = 0.0003342 * "band10" + 0.1 2) BT = (1321.08 / Ln((774.89 / "%TOA%") + 1)) – 273.15 3) For Landsat TM NDVI = (Band 5– Band 4/(Band 5 + Band 4) 4) PV = Square(("%NDVI%" - NDVImin)/(NDVImax – NDVImin)) 5) E = 0.004 * "%PV%" + 0.986 6) LST = ("%BT%" / (1 + (0.00115 * "%BT%" / 1.4388) * Ln("%e%"))) If You Like My Video Please #SUBSCRIBE To My Channel For Latest Update.

This video provides a quick tutorial on how to calculate the Enhanced Vegetation Index (EVI), in this case using Sentinel-2 satellite imagery in QGIS, although the formula applies to any imagery and software. EVI is a vegetation index designed to give enhanced contrast in areas of dense foliage or canopy cover, making use of the blue band as well as the red and near-infrared bands used by many other indices like NDVI.

The "enhanced vegetation index" is an 'optimized' index designed to enhance the vegetation signal with improved sensitivity in high biomass regions and improved vegetation monitoring through a de-coupling of the canopy background signal and a reduction in atmosphere influences. EVI is computed following this equation: " EVI= G \times \frac " where NIR/red/blue are atmospherically-corrected or partially atmosphere corrected surface reflectances, L is the canopy background adjustment that addresses non-linear, differential NIR and red radiant transfer through a canopy, and C1, C2 are the coefficients of the aerosol resistance term, which uses the blue band to correct for aerosol influences in the red band. The coefficients adopted in the MODIS-EVI algorithm are; L=1, C1 = 6, C2 = 7.5, and G = 2.5. Whereas the Normalized Difference Vegetation Index is chlorophyll sensitive, the EVI is more responsive to canopy structural variations, including leaf area index , canopy type, plant physiognomy, and canopy architecture. The two vegetation indices complement each other in global vegetation studies and improve upon the detection of vegetation changes and extraction of canopy biophysical parameters. . Another difference between Normalized Difference Vegetation Index and EVI is that in the presence of snow, Normalized Difference Vegetation Index decreases, while EVI increases . Starting 2000, and after the launch of the two MODIS sensors on Terra and Aqua by NASA, EVI was adopted as a by NASA and became extremely popular with users due to its ability to eliminate background and atmosphere noises, as well as its non saturation, a typical NDVI problem. EVI is currently distributed for free by the USGS LP DAAC. Wiz Science™ is "the" learning channel for children and all ages. SUBSCRIBE TODAY Disclaimer: This video is for your information only.

This short tutorial is the first video (Part 1) of the “Getting Started with MODIS Version 6 -Vegetation Indices Data” video series. This video focuses on the National Aeronautics and Space Administration’s (NASA) Terra and Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Version 6 Vegetation Indices data distributed by NASA’s Land Processes Distributed Active Archive Center (LP DAAC). The LP DAAC is one of twelve NASA Earth Observing System Data and Information System (EOSDIS) DAACs. It is located at the United States Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota. The LP DAAC ingests, archives, processes and distributes NASA Earth science land processes data and information. In this short tutorial, we will cover the MODIS Version 6 Vegetation Indices data products, improvements in Version 6 products over Version 5 products, and how to search for and download these data using the NASA Earthdata Search Client data access tool To learn more about MODIS Version 6 Vegetation Indices data and other data products distributed by the LP DAAC please visit https://lpdaac.usgs.gov/.

This tutorial demonstrates how to compute Spectral Profile for for Vegetation, Built Up and Water class in Landsat 8 using ERDAS Imagine. Spectral signature is the reflectance as a function of wavelength, each material has a unique signature, therefore it can be used for material classification. The Spectral Profile Viewer allows you to visualize the reflectance spectrum of a single pixel through many bands.

Vigor mapping is nothing new to the wine industry. NDVI imaging has been used by vineyard owners and managers for nearly forty years. Did you know, however, that there are many errors associated with NDVI imaging? That's why scientists at VineView use the EVI, or Enhanced Vegetation Index, for vigor mapping. EVI eliminates errors associated with NDVI imaging, including those caused by soil variations, shadows, and solar incidence angles that typically plague NDVI imaging.
