ArcGIS has a suite of extensions that provide extended capabilities to the core product. The categories of extensions include analysis, data integration and editing, publishing, and cartography. Also available are extensions that are solutions for specific markets.
Three-dimensional visualization and analysis; includes ArcGlobe and ArcScene applications. Also includes terrain data management and geoprocessing tools.
ArcGIS 3D Analyst extension extends ArcGIS to be a fully functioning 3D GIS system. It allows you to view, manage, analyze, and share your 3D GIS data.
Analyze and validate data with a variety of checks that allow you to check for both spatial and attribution conditions. Additionally, you can also sample data, validate metadata values against a schema, and check valency on network features. The results of the analysis or validation are stored in a table, where you can update the correction or verification status.
Advanced statistical tools for surface generation and analyzing and mapping continuous datasets. Exploratory spatial data analysis tools provide insights about your data distribution, global and local outliers, global trends, level of spatial autocorrelation, and variation among multiple datasets.
Perform advanced routing and network analysis supporting
Generate, visualize, and manipulate diagrams from network data coming from a geodatabase or any data that has explicit attributes showing connectivity. You can do the following:
A broad range of powerful raster modeling and analysis features allow you to create, query, map, and analyze cell-based raster data. ArcGIS Spatial Analyst extension also allows integrated raster-vector analysis and adds more than 170 tools to the ArcGIS geoprocessing framework.
Designed for mapping objects that move or change status through time, Tracking Analyst gives you the power to do the following:
Data integration and editing
Directly read and employ more than 100 common GIS vector data formats, including many of the evolving GML specifications. In addition, GIS data can be delivered in a variety of formats. For example, data sources, such as advanced computer-aided design (CAD) datasets with extended entity attributes, MapInfo datasets, Intergraph GeoMedia datasets, and various GML files, can be accessed, displayed, and used directly in ArcGIS. Deliver GIS data to others in a variety of vector data formats (more than 70 supported formats).
At the 10 release, the ArcGIS Data Interoperability extension is a separate setup available on the ArcGIS for Desktop media.
Perform raster-to-vector conversion tasks on scanned documents, including raster editing, raster snapping, manual raster tracing, and batch vectorization.
Manage post-processed bathymetric data and metadata. You can leverage the central geodatabase, referred to as the Bathymetric Information System (BIS), to interact with and manage large volumes of raster data and selected soundings on an ArcGIS for Desktop platform. The extension provides a simple interface for:
Manage hydrographic information and products to generate electronic, hard-copy, and raster navigational products that are compliant with standards. The following can be produced using the Nautical Solution:
Efficiently manage aeronautical information, products, and integrated workflows to generate navigational products compliant with aviation standards.
Facilitate large-scale data production with tools that support data creation, maintenance, validation, and cartographic production.
