Presentation Transcript

  1. Overview • The 3D scene document: a new ArcView document type • 3D Analysis & Modeling • Data sources for 3D display and analysis • 3D visualization_

  2. Overview • The 3D scene document: a new ArcView document type • 3D Analysis & Modeling • Data sources for 3D display and analysis • 3D visualization_

  3. 3D Scene Document • 3D Scene: document type for viewing data in 3 dimensions

  4. 3D Scene Document • Table of contents & viewer in separate windows

  5. 3D Scene Document • Viewer “floats” outside of application window

  6. selection of 3D shapes or other vector features save as BMP or JPEG selection of 3D graphical primitives rotateviewer navigate zoom buttons The 3D scene GUI • 3D Scene GUI • Buttons & tools on same bar

  7. Overview • The 3D scene document: a new ArcView document type • 3D Analysis & Modeling • Data sources for 3D display and analysis • 3D visualization_

  8. 3D Analysis & Modeling • Viewing/converting 3D data • Contouring • Profiling • Color hillshade mapping • Steepest descent • Viewshed and visibility • Slope and aspect calculation_

  9. view 3D data sets • convert 2D data to 3D 3D Analysis & Modeling • 3D Analyst functions

  10. 3D Analysis & Modeling: Contouring • Surface contouring

  11. line shows green (visible)red (not visible) • surface profile is generated 3D Analysis & Modeling: Profiling • Composite tool for line of sight & profiling

  12. 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

  13. 3D Analysis & Modeling: Viewshed and visibility • Viewshed and visibility analysis • delineation of areavisible from a point

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

  15. single attribute display multiple attribute display 3D Analysis & Modeling: Feature extrusion • Feature extrusion

  16. Break Entertainment Star Wars Kid

  17. Overview • The 3D scene document: a new ArcView document type • 3D Analysis & Modeling • Data sources for 3D display and analysis • 3D visualization_

  18. 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_

  19. 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_

  20. Data sources for 3D display and analysis • TIN data sources • Vector-based data type • Triangulated Irregular Network • Composite of point, line, and polygon features

  21. Data sources for 3D display and analysis • TIN data model • Complex or simple structure where necessary to model surface

  22. 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_

  23. Overview • The 3D scene document: a new ArcView document type • 3D Analysis & Modeling • Data sources for 3D display and analysis • 3D visualization_

  24. 3D visualization • 3D visualization • Seeing 2D features in 3D by draping and extruding • Legend editing • Navigation and moving around in real-time • Real-time perspective viewing_

  25. 3D visualization: Surface draping • 3D surface draping • Any 2D theme can be displayed draped over a surface • streams • contour lines • digital orthophoto

  26. 3D visualization: Color hillshade mapping • Draping with color ramping

  27. 3D visualization: Color hillshade mapping • Draping, color ramping, and hillshading

  28. base height of feature • offset from base height • extrusion 3D visualization: Seeing 2D features in 3D by draping and extruding • Display of 2D theme can be altered

  29. orthophoto & streamsdraped on DEM • DEM as color hillshade& streams draped on DEM 3D visualization: Seeing 2D features in 3D • Draping rasters/features on surfaces

  30. points or polygonsextruded by an attribute value • lines extruded by a constant 3D visualization: Seeing 2D features in 3D • Extruding features

  31. point • line • polygon 3D visualization: TIN legend editing • Display of TIN can be altered

  32. 3D visualization: TIN legend editing • Display of TIN can be altered

  33. 3D visualization: TIN legend editing • Display of TIN can be altered

  34. navigate tool 3D visualization: Navigating the 3D Scene Document • Complex tool for navigation

  35. 3D visualization: Navigation and moving around in real-time • “Real-time” = automatic refresh of viewer as perspective changes
