Presentation Transcript
slide1

Overview

  • 3D Analysis & Modeling
  • A new ArcView document type: the 3D scene document
  • Data sources for 3D display and analysis
  • 3D visualization
slide2

view 3D data sets

  • convert 2D data to 3D
  • 3D Analysis & Modeling
slide3

feature extrusion

  • 3D Analysis & Modeling
slide4

new document type

  • 3D Scene Document
slide5

3D Scene Document

  • TOC & viewer in separate windows
slide6

selection of 3D shapes or other vector features

save as BMP or JPEG

zoom buttons

rotate viewer

navigate

  • The 3D scene GUI
slide7

Data sources for 3D display and analysis

  • Grid data sources
  • TIN data sources
  • 2D shapefiles and raster data
  • 3D shapefiles
slide8

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
slide9

TIN data sources

  • Different vector data type
  • Triangulated Irregular Network
  • Point, line, and polygon features
slide10

TIN data sources

  • Complex structure where necessary to model surface
slide11

2D shapefiles and raster data

  • any 2-D theme can be displayed draped over a surface
  • streams
  • contour lines
  • digital orthophoto
slide12

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
slide13

3D visualization

  • Legend editing
  • Seeing 2D features in 3D by draping and extruding
  • Navigation and moving around in real-time
  • Real-time perspective viewing
slide14
