      Tundra, a major zone of treeless level or rolling ground found in cold regions, mostly north of the Arctic Circle (Arctic tundra) or above the timberline on high mountains (alpine tundra). Tundra is known for large stretches of bare ground and rock and for patchy mantles of low vegetation such as mosses, lichens, herbs, and small shrubs. This. Contour lines are a familiar way to represent surfaces on a map. A contour is a line through all contiguous points with equal height. Contours are delivered as a polyline ESRI shapefile with a set interval. 3D PDF: A compressed Universal 3D model embedded in a PDF document, viewable in any PDF viewer - e.g. Adobe Acrobat Viewer PDF.

    Section - Landscape Soil 1 J Section - LANDSCAPE SOIL (TOPSOIL) Description. Landscape soil shall be used for soil preparation and amending existing soil for landscape areas, erosion control areas, and lawn areas. The terms landscape soil and topsoil can be used interchangeably for this specification. An example would be determining the amount of carbon present in the soil based on landform over a landscape, derived from GIS maps, vegetation types, and rainfall data for a region. Remote sensing work has been used to extend landscape ecology to the field of predictive vegetation mapping, for instance by Janet Franklin.

    the California Vegetation Classification (Sawyer and Keeler-Wolf ms). Purpose of Mapping The purpose of mapping vegetation goes beyond cataloging and identifying all the vegetation types in an area. The pur-pose of a map is to graphically display the location of the different vegetation types and emphasize their spatial rela-tionships. Survey Staff.

Areal correspondence was evaluated with the intersection/union ratio for vegetation and soil polygons. Ranks of vegetation communities according to their areal correspondence with the soil body were generally inconsistent.

The dissected soil showed the greatest amount of consistency in areal correspondence between upland and lowland : Janet Bilton. Comparison of soil and vegetation map delineation shapes and areal correspondence.

The latter objective was achieved in\ud a preliminary study involving a small number of soil-vegetation\ud complexes. Data on shape similarity and areal\ud correspondence were collected using a digital planimeter.\ud The methodology developed was then.

These qualitative discussions are based on the field observa-tionsof the surveyor, who then attempts to summarize the.

RS is a convenient tool to predict drought. This prediction is based on vegetation mapping. Drought causes structural changes in vegetation which affect its spectral reflectance.

Temporal monitoring of vegetation indices in a region and comparison with the values of a normal year will reveal the onset of drought and its areal extent.

Understanding the locations of certain vegetation classes within a region can be very useful in predicting other environmental characteristics, such as wildlife habitat, springs, soil types, and much more.

Many remote sensing techniques are available to accomplish this in areas that have large amounts of foliar cover and dense vegetation. GIS and Soil. Chapter (PDF Accurate soil data are needed in order to develop reliable and high-resolution soil maps for hydrological analysis.
