About 3D Analyst |
|
ArcGIS 3D Analyst is an ArcGIS extension that provides advanced tools for three-dimensional visualization, analysis, and surface generation. ArcGIS 3D Analyst enables both novice and advanced users to create dynamic 3D models and interactive maps that elevate the visualization and analysis of geographic data. |
|
Using the ArcGIS 3D AnalystM extension you can easily perform three-dimension line-of-sight analysis and create surfaces such as TINs. Using any of the standard ArcGIS supported formats, both two-dimensional and three-dimensional data can be viewed in a three-dimensional perspective by using attributes. For example, you can easily extrude building footprints to three-dimensional structures, lines to walls, and points to lines. This allows you to build highly interactive and navigable views without having to create new data. If your data has three-dimensional coordinates, the applications will use this data and place it correctly in three-dimensional space. |

Your data can also be viewed from a global perspective with the ArcGlobe application. Leveraging extremely efficient and highly optimized data retrieval and display techniques, ArcGlobe provides seamless and fast access to virtually unlimited volumes of geographic information. ArcGlobe can easily and intelligently handle raster, vector, and terrain data sets representing data from local to global scale with performance exceeding traditional two-dimensional mapping.
Using standard interactive mapping tools, users can also pan, query, and analyze data at any scale, or they can zoom right in to their local area and view high-resolution spatial data, such as parcels or detailed aerial photographs, of their area of interest. |

| Why Use ArcGIS 3D Analyst? |
|
ArcGIS 3D Analyst provides the tools to model and visualize your data in three dimensions, giving you a realistic perspective of your data. Patterns and trends appear in three dimensions that might not be discovered in a flat, two-dimensional view.
With ArcGIS 3D Analyst you can:
- Create and analyze surfaces
- Build surface models from many supported data formats including CAD, shapefiles, coverages, and images
- Perform interactive perspective viewing, including pan and zoom, rotate, tilt, and fly-through simulations, for presentation and analysis
- Model real-world surface features such as buildings
- Model subsurface features - wells, mines, groundwater, and underground storage facilities
- Generate three-dimensional surfaces on the fly from attributes
- Apply data normalization and exaggeration on the fly
- Drape two-dimensional data on surfaces and view in three dimensions
- Calculate surface area, volume, slope, aspect, and hillshade
- Apply various data layer effects such as transparency, lighting, shading, and depth priority
- Generate contours as two-dimensional or three-dimensional features
- Perform viewshed and line-of-sight analysis, spot height interpolation, profiling, and steepest path determination
- Query three-dimensional data based on attribute or location
- Export data for display on the Web using VRML
- Create animations for visualization (AVI, MPEG, and QuickTime)

| Who Uses ArcGIS 3D Analyst? |
|
Any user who needs a three-dimensional understanding of spatial data can use ArcGIS 3D Analyst. ArcGIS 3D Analyst users leverage the visualization capabilities for improved communication and representation of GIS data and ideas. For example, users can examine the visual impact of building new structures; analyze atmospheric, surface, and subsurface pollution dispersion; study the income distribution in their community; and much more.
Some of the application areas include:
- Agriculture production analysis
- Geological exploration
- Environmental monitoring
- Meteorological analysis
- Hydrology modeling
- Archaeological visualization and mapping
- Forest modeling
