2. Three Transformers for Raster Lovers
Take a DEM and make it all with:
RasterHillShader (added in 2013)
RasterAspectCalculator
RasterSlopeCalculator
Hill shading
Aspect
Slope
3. Three Definitions for Raster Beginners
Hill shading – simulates the cast shadow thrown
upon a raised relief map
Aspect – horizontal direction to which
a mountain slope faces
Slope – the inclination of the surface to
the horizontal
Hill shading
Aspect
Slope
4. Three Dimensions for Inquisitive Viewers
Generate a surface (SurfaceModeller) from DEM
Apply Aspect/Hill Shade/Slope as a texture
(AppearanceSetter)
Save to a 3D format (PDF 3D, Geodatabase, OBJ)
5. Three Demos for Everyone
Simple Use of
RasterAspectCalculator, RasterSlopeCalculator, an
d RasterHillShader
Making textured PDF 3D
Slope Analysis
Dean: Why is this useful?Slope used in slope stability, slide or avalanche hazard, road construction, hydrology etcAspect combined with slope used in solar calculations for farming, solar power, snow field analysisHill shading used in cartography
Therasters can be used as textures (note that some formats such as PDF 3D require RGB, so if you make a demo, Interpretation coercing might be needed)
