How To: Create a 3D surface view in ArcInfo Workstation

Summary

An introduction to creating 3D models of landscapes using ArcInfo Workstation.

Procedure

  1. Set the SURFACE. This is the elevation lattice for the surface commands to work on. Think of this as the canvas you will draw on top of. You can also use a tin.

    Code:
    Arcplot: SURFACE LATTICE mysurface
    Arcplot: SURFACEDEFAULTS

  2. Orient the view. Set the environment for how and where the surface will be viewed, its resolution, and how much of it will be displayed.

    Code:
    Arcplot: SURFACEOBSERVER 10 10 1000
    Arcplot: SURFACETARGET 0 0 500
    Arcplot: SURFACEVIEWFIELD 30 30 30 30
    Arcplot: SURFACELIMITS PAGE
    Arcplot: SURFACEEXTENTS 0 0 10000 10000
    Arcplot: SURFACERANGE 100 5000
    Arcplot: SURFACEZSCALE 2
    Arcplot: SURFACERESOLUTION SURFACE

  3. Drape the features. These commands 'melt' vector or raster data over the surface. You can use many of ARCPLOT drawing commands with SURFACEDRAPE.

    Code:
    Arcplot: LINESYMBOL 15
    Arcplot: SURFACEDRAPE MESH FISHNET 10
    Arcplot: LINESYMBOL 2
    Arcplot: SURFACEDRAPE ARCS myroads
    Arcplot: LINESYMBOL 4
    Arcplot: SURFACEDRAPE ARCS mystreams
