Presentation Transcript

  1. Overview • 3D Analysis & Modeling • A new ArcView document type: the 3D scene document • Data sources for 3D display and analysis • 3D visualization

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

  3. feature extrusion • 3D Analysis & Modeling

  4. new document type • 3D Scene Document

  5. 3D Scene Document • TOC & viewer in separate windows

  6. selection of 3D shapes or other vector features save as BMP or JPEG zoom buttons rotate viewer navigate • The 3D scene GUI

  7. Data sources for 3D display and analysis • Grid data sources • TIN data sources • 2D shapefiles and raster data • 3D shapefiles

  8. 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

  9. TIN data sources • Different vector data type • Triangulated Irregular Network • Point, line, and polygon features

  10. TIN data sources • Complex structure where necessary to model surface

  11. 2D shapefiles and raster data • any 2-D theme can be displayed draped over a surface • streams • contour lines • digital orthophoto

  12. 3D shapefiles: A new feature type • 2-D shapefiles have only X & Y coordinates • 3-D shapefiles incorporate a Z coordinate • Z-value can represent any numerical phenomenon • Any 2-D shapefile can be converted to a 3-D shapefile • Conversion based on a constant, attribute value, or surface model

  13. 3D visualization • Legend editing • Seeing 2D features in 3D by draping and extruding • Navigation and moving around in real-time • Real-time perspective viewing

  14. point • line • polygon • 3D visualization: Legend editing • display of TIN can be altered

  15. base height of feature • offsets • extrusion • 3D visualization: Seeing 2D features in 3D by draping and extruding • display of 2-D theme can be altered

  16. DEM & streamsdraped on DEM • orthophoto & streamsdraped on DEM • 3D visualization: Seeing 2D features in 3D by draping

  17. plot centers extruded by anattribute value and • streams extruded by a constant • 3D visualization: Seeing 2D features in 3D by extruding

  18. navigate tool • Navigating the 3D Scene Document

  19. 3D visualization: Navigation and moving around in real-time
