VRI Data Analysis

 Smallest Polygon is .000000126 Ha. Largest Polygon is 14755.71 Ha.

Most prominent species in Species_cd_1 is Lodgepole Pine.

Total area of polygons containing birch is 159591.25 Ha.

DBH stands for diameter at breast height.

Total volume of timber where spruce is leading species is  2,512,688 cubic meters.

  1. Volume of  Birch is 2084408 cubic meters.
  2. Volume of Aspen is 10566003 cubic meters.

Raster Exercise

1. A map projection on which the azimuths of all points are shown correctly with respect to the center. Azimuthal projections result from projecting a spherical surface onto a plane.

2. Euclid is any three non-collinear points determining a unique triangle and a unique plane. Is closely connected with computational geometry, computer graphics, convex geometry and discrete geometry. The Euclidean distance functions measure straight-line distance from each cell to the closest source.

3. The Pythagorean Theorem: The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c). a2+b2=c2.

 
4.  The Map Algebra language provides building blocks that can be used individually or in conjunction with one another to solve problems. When combining the blocks, a syntax or set of rules must be followed for ArcGIS Spatial Analyst to perform the requested task. Map Algebra creates new features and attribute relations by overlaying the features from two input map layers. Features from each input layer are combined to create new output features.
 
5.  The 7  functions of Spatial Analyst: 
  • Density analysis – Distributes a measured quantity of an input point layer throughout a landscape to produce a continuous surface.
  • Surface generation –  
  • Surface analysis –   Creates new surfaces from existing datasets.
  • Hydrologic analysis – Specialized tools for working with and deriving new information from hydrologic and landscape data.
  • Geometric transformation –  Used to ensure that each data layer precisely overlays the other data layers. 
  •  Generalization – Removal of detail from a data layer to make processing or visualization easier at smaller scales. 
  • Resolution altering – changing the resolution of an existing raster. This speeds up processing and reduces data size. 
                                                                            

5 Buffer Zones

                                                                                       

  1.  Logging buffers on streams, rivers and lakes to protect fish habitats.
  2. Military no fly zones to prevent aircraft from entering areas of warfare.
  3. No hunting zones around parks and wildlife areas to prevent mass slaughter of animals.
  4. Buffers around areas of illness to prevent illness of others.
  5. Buffers around whale watching areas to prevent injury and stress to the whales.
