    4.6. Relationship between land-use/land-cover and Normalized difference vegetation index Normalized difference vegetation index maps extracted from near infrared and red-bands of the study periods indicated that different LU/LC has different NDVI values. As NDVI is related with the vegetation condition, the value varies from area to area based on vegetation intensity of the sites. Plantation and shrub land have the highest NDVI value than other classes (Fig. 4.6). Figure 4.6: Zonal statistical

  • Pine Forests Of The Colorado Plateau

    1222 Words  | 5 Pages

    Ponderosa pine forests of the Colorado Plateau cover a large portion of the higher mesas and mountains from elevations of 6000 to approximately 8000 feet.

  • Modeling The Agrometeorological Indices Of The Surface Temperature

    1160 Words  | 5 Pages

    uncertainties in models which use the MODIS 8-day that is a composite of once-daily overpass at ~ 10:30 h local time. In this case, the radiometric temperature is determined under a view angle at the satellite overpass time, using emissivities based on vegetation classes at a 1-km grid that differs from that of the MODIS pixel location. The parameterizations involved in the agrometeorological indices by using the SAFER algorithm in this chapter were done in Brazil with simultaneous satellite and field measurements

  • Term Paper On The Greenock Region, South Australia

    2953 Words  | 12 Pages

    McDougall 1607680 Introduction Vegetation is important to conserve, especially in or near built up areas where it can easily become obsolete due to expansion or otherwise. In areas such as the Greenock region, South Australia, vegetation often gets split into fragments spread across the landscape. This has many implications for the conservation of both vegetation and animals in the region. In order to revegetate and conserve any vegetation in the area, a suitable site (or sites) must

  • Persuasive Essay On Forest Fires

    1830 Words  | 8 Pages

    Forest fires are not uncommon in the west coast but rising temperatures and global climate change have been leading to drier and drier seasons in many areas, making wildfires a growing concern. The west coast has both the largest number of wildfires as well as the most severe, starting from 100 acres and above (Donegan, 2016). Southern California is a frequent location for wildfires each year due to its dry weather and hot temperatures during the summer, and the Santa Clarita region alone has had
