ENVI Tools for ArcGIS®

---

Image Processing and Analysis Tools – For the ArcGIS® Toolbox

Organizations around the globe increasingly depend on geospatial information in critical decision making processes. Whether you are a defense or intelligence analyst, an urban planner, resource manager or an emergency responder the need to have accurate and timely information about an area of interest is growing exponentially. In order to meet these growing demands software technologies must provide workflows that are increasingly interoperable, easier to use and provide data to large communities of users in a timely manner.

Geospatial imagery is a powerful and cost effective way to update geodatabases with the most current and detailed information about a geographic area. Exelis and Esri®, as industry leaders respectively in remote sensing software technologies and geographic information systems, have worked together in a multi-year effort to integrate their two software technologies. This effort has resulted in the seamless integration of ENVI and the ArcGIS® platform to deliver the power of image analysis to the GIS environment. Now, the integration of these two technologies takes the next step – ENVI tools for ArcGIS®.

Access Proven ENVI Functionality as Tools within ArcGIS

The scientifically proven image analysis capabilities of ENVI are available as discrete tools in the ArcGIS toolbox and accessible directly from ArcGIS desktop and server environments. Upon installation of ENVI products, a selection of powerful image processing and analysis tools will be available within ArcGIS. These tools will deliver the popular image processing and analysis functionalities most useful for providing important geospatial information to GIS applications including:

Detecting change over time Finding features of interest or anomalies Identifying and classifying features or land cover Categorizing terrain

Correcting for atmospheric conditions Detecting and mapping lines of communication Analyzing LiDAR data

Add Image Analysis to Your GIS Models and Application

Information from geospatial imagery is often only a part of the data needed to get a complete representation of an area of interest. With ENVI tools for ArcGIS, image analysis processes can be integrated into GIS models to add information from imagery to a variety of applications. Incorporating feature extraction and classification tools into an urban planning model can deliver accurate and robust information regarding impervious versus pervious surface areas for a metropolitan area, and increase the accuracy and currency of land cover data. Adding change detection and vegetation index tools to a model for resource management can give you complete information about environmental impacts from man-made or naturally occurring change. The ability to add image analysis processes to GIS models further abstracts the complexities of image analysis and gives the power of geospatial information extraction to GIS users without requiring remote sensing expertise.

Customizable ENVI Tools and Models

One of the most valuable features of ENVI has always been the access to its underlying development environment, IDL. This open architecture platform also extends to ENVI tools for ArcGIS, giving users the ability to readily customize ENVI tools or to create new image analysis tools from the full compliment of ENVI functionality. Available with a desktop deployment of ENVI plus IDL, developing customized ENVI tools can be done using simple IDL scripting and wrappers that facilitate the integration of ENVI tools with the ArcGIS platform.

Publishing to ArcGIS® Server for Enterprise and Web Applications

ENVI tools for ArcGIS will be deployed in several different scenarios, used individually in the ArcGIS desktop or used to develop imagery services that can be published to ArcGIS Server for use across a workgroup or enterprise. For ArcGIS Server environments, ENVI for ArcGIS Server will allow multiple and concurrent uses of ENVI image processing tools. ENVI for ArcGIS Server will expose ENVI capabilities natively within ArcGIS Server allowing users to leverage server class resources to speed processing and analysis workflows on large data stores. ENVI processing tools will also be included in geoprocessing models and applications for desktop users, for batch analysis, and over the internet as web services in a variety of clients for remote users.
