ArcView 3D Analyst supports three primary data types for modeling three-dimensional
features—grids, triangulated irregular networks (TINs), and shapefiles (2D and 3D).
Grids and TINs are used to model continuous data or surfaces. Three-dimensional vector
features, where X, Y, and Z values are stored for every vertex, let users capture and
precisely represent geographic features.
Both two-dimensional and three-dimensional data can be viewed in perspective using the
ArcView 3D Analyst 3D Scene Viewer. With the viewer, a user can rotate, zoom in and
out, and pan the data from any angle in a scene.
With ArcView 3D Analyst, users can perform a wide range of activities.
Create realistic surface models from multiple input sources.
Determine height at any location on a surface.
Find what is visible from an observation point.
Calculate the surface area and volume between surfaces.
Work with three-dimensional vector features to make realistic models of the threedimensional
world.
Visualize data in three dimensions.
View in pan and zoom mode as well as interactively tilt and rotate data, featuring
fly-through simulation.
Turn maps into Web-viewable VRML files.
Allow creation of TINs from any combination of point, line, and polygon feature
types or from grids.
Import gridded elevation models including USGS DEMs.
