Overview

  • The 3D scene document: a new ArcView document type

  • 3D Analysis & Modeling

  • Data sources for 3D display and analysis

  • 3D visualization_


Data sources for 3d display and analysis l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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_
