Presentation Transcript


Slide1 l.jpg

  • Overview

  • 3D Analysis & Modeling

  • A new ArcView document type: the 3D scene document

  • Data sources for 3D display and analysis

  • 3D visualization


Slide2 l.jpg

  • view 3D data sets

  • convert 2D data to 3D

  • 3D Analysis & Modeling


Slide3 l.jpg

  • feature extrusion

  • 3D Analysis & Modeling


Slide4 l.jpg

new document type

  • 3D Scene Document


Slide5 l.jpg

  • 3D Scene Document

  • TOC & viewer in separate windows

  • The 3D scene GUI


Slide7 l.jpg

  • Data sources for 3D display and analysis

  • Grid data sources

  • TIN data sources

  • 2D shapefiles and raster data

  • 3D shapefiles


Slide8 l.jpg

  • 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 l.jpg

  • TIN data sources

  • Different vector data type

  • Triangulated Irregular Network

  • Point, line, and polygon features


Slide10 l.jpg

  • TIN data sources

  • Complex structure where necessary to model surface


Slide11 l.jpg

  • 2D shapefiles and raster data

  • any 2-D theme can be displayed draped over a surface

  • streams

  • contour lines

  • digital orthophoto


Slide12 l.jpg

  • 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 l.jpg

  • 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 l.jpg

  • point

  • line

  • polygon

  • 3D visualization: Legend editing

  • display of TIN can be altered


Slide15 l.jpg

  • 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
