3d analysis modeling9

view 3D data sets

  • convert 2D data to 3D
3D Analysis & Modeling
  • 3D Analyst functions
3d analysis modeling profiling

line shows green (visible)red (not visible)

  • surface profile is generated
3D Analysis & Modeling: Profiling
  • Composite tool for line of sight & profiling
3d analysis modeling steepest descent

Steepest descent tool; use with TIN

3D Analysis & Modeling: Steepest descent
  • Creates a 3D graphic line of steepest downward descent
  • can be viewed in 3D
  • creates a graphic on the view
3d analysis modeling viewshed and visibility
3D Analysis & Modeling: Viewshed and visibility
  • Viewshed and visibility analysis
  • delineation of areavisible from a point
3d analysis modeling slope and aspect calculation

slope for each cell

  • aspect for each cell
3D Analysis & Modeling: Slope and aspect calculation
  • Maximum slope & aspect (slope direction azimuth)

Data sources for 3D display and analysis
  • Source of 3rd Dimension
    • Surfaces
      • Grid data sources
      • TIN data sources
    • 2D shapefiles and raster data
    • 3D shapefiles_
data sources for 3d display and analysis19
Data sources for 3D display and analysis
  • Grid data sources
    • Typical grid data sets from Spatial Analyst
    • Create from any other supported data set
    • Download DEM data
    • Displayed in 3D based on cell values_
data sources for 3d display and analysis20
Data sources for 3D display and analysis
  • TIN data sources
    • Vector-based data type
    • Triangulated Irregular Network
    • Composite of point, line, and polygon features
data sources for 3d display and analysis21
Data sources for 3D display and analysis
  • TIN data model
    • Complex or simple structure where necessary to model surface
data sources for 3d display and analysis22
Data sources for 3D display and analysis
  • 3D Shapefiles
    • 2D shapefiles have only X & Y coordinates as part of data structure
    • 3D shapefiles incorporate a Z coordinate as part of data structure
    • Z-value can represent any numerical phenomenon
    • Any 2D shapefile can be converted to a 3D shapefile
    • Conversion based on a constant, attribute value, or surface model_
