Home Range and GIS Eva Strand CNR Remote Sensing and GIS Lab

Slide 3

What is Home Range? The portrayal of a creatures space utilize The home reach is accepted to contain the key prerequisites, for example, nourishment, water and cover Wildlife Techniques Manual

Slide 4

Home extent qualities Home ranges regularly cover (instead of domains) Home reach size has been associated to body size Can clarify a creatures natural examples Can enhance comprehension of environmental connections

Slide 5

Telemetry information or GPS neckline Tabular information in Excel (2003) .dbf or .txt configuration can be straightforwardly foreign made to ArcGIS or ArcView

Slide 6

Telemetry information or GPS neckline

Slide 7

Home Range Methods Minimum Convex Polygon Harmonic Mean Kernal Jennrich-Turner

Slide 8

Minimum Convex Polygon Minimum Convex Polygon (MCP) is characterized as the polygon drawn around the peripheral focuses

Slide 9

Fixed bit home extent is presently prescribed Contours The measure of the part home extent is delicate to the transmission capacity esteem (h) utilized!

Slide 10

Kernel Density Functions n – number of areas h – smoothing parameter d – separation from the area x, y

Slide 11

… .a couple of suspicions Locations are autonomous sufficiently large example size Smoothing parameter (bit estimators)

Slide 12

Bandwidth, h-component, smoothing parameter Least Squares Cross Validation (LSCV) Currently prescribed Tendency to undersmooth, makes different nearby minima High variability Likelihood Cross Validation (CV) Novel strategy (Horne and Garton 2006) Performs better for littler specimen sizes (< 50) Better fit and less variability Normal or Reference technique (h ref ) Scaled-REF (h ref is duplicated by an altered extent) Gitzen et al. 2006 Horne and Garton 2006

Slide 18

Animal Movement Extension Will use any sort of point information that can be acquired into ArcView Works any projection* Works on any chose subset of data* Produces Coverages, Grids, or Tables i.e. all yield is perfect with ArcView *Except G in = G out 2 G = Garbage U.S. Bureau of Interior U.S. Geographical Survey Alaska Biological Science Center Glacier Bay Field Station
