How can we help?

ENVI  |  Extensibility

ENVI is written in IDL®, a modern programming language that provides the ability to extend or customize ENVI features and functionality. The ENVI API lets users add their own proprietary algorithms, extend existing tools and models and automate workflows for batch processing. ENVI is also accessible via a Python client library.


Perform visual programming and write custom tasks and workflows

If you aren’t a programmer, the ENVI Modeler is a visual programming tool that makes it easy to perform batch processing and effortlessly create custom image processing workflows without having to write a single line of code. In addition, if you are an Esri user, you can run your ENVI Modeler workflows in ArcGIS Pro or ArcMap. With ENVI Modeler’s intuitive user interface, you can also run processing in the cloud, or on remote servers, with the click of a button.

For the developer, ENVI enables users to write custom tasks using templates that define the input and output parameters required for data processing. These discrete processing tasks are de-coupled from the desktop and can easily be chained together to build custom workflows. A task can be written once and then run on desktop or enterprise environments.

ENVI  |  Integration with ArcGIS®

ENVI is tightly integrated with Esri’s ArcGIS platform and lets GIS users seamlessly access and analyze imagery to solve critical problems with confidence. ENVI analytics can be accessed from within any ArcGIS environment and results can be displayed directly from ArcGIS Pro, ArcMap or via ArcGIS Online. By extending ArcGIS with ENVI analytics you can derive quantitative, actionable results from remotely sensed data, share them across your organization and use the information to make better decisions, regardless of your experience.

With the integration of ENVI’s task-based analytics into ArcGIS, it is easy to implement all of the advanced ENVI processing techniques on the desktop or in the enterprise. Additionally, there are automated workflows exposed out-of-the-box in ArcGIS making it easy to deliver expert-level results regardless of image analysis experience.


Python integration

L3Harris has exposed ENVI tasks through a Python client library, ENVI Py, which enables users to access ENVI’s suite of image processing tools directly from ArcMap or ArcGIS Pro. Users also have access to out-of-the-box toolboxes for ArcMap or ArcGIS Pro. This suite enables ArcGIS users to take advantage of ENVI’s advanced imagery capabilities where and how they want.


Batch process and create custom workflows

ENVI Modeler helps you perform batch processing and effortlessly create custom image processing workflows without writing a single line of code. These workflows can be published directly to ArcGIS Pro.

ENVI Server

ENVI Server lets you run processing in parallel or in the background using ENVI desktop and allows you to take advantage of modern hardware. With ENVI Server, you no longer need to wait for ENVI's progress bars to finish before getting to the next step of your workflows. One of the best features about ENVI Server is that it is free to anyone who has access to ENVI 5.6 or newer. There is no additional fee, license or module that you need to purchase to use ENVI Server.

You can also use ENVI as a client to ENVI Server – meaning that, any machine with ENVI Server and access to the same data as your local ENVI session, can accept processing from ENVI. You can use the ENVI Modeler or ENVI dialogs to send processing to ENVI Server. This allows you to keep using ENVI the same way that you always have to easily take advantage of the power of ENVI Server.

Leverage image analysis in the cloud

ENVI Server is a great way to try out enterprise processing. If you have immense volumes of data to analyze, then scalable processing in the cloud might be what you need. ENVI makes it easy to take workflows created with the ENVI Modeler or the ENVI API and deploy those to cloud-hosted processing instances – write once and deploy anywhere.

Implementing cloud based image analytics reduces hardware and software costs and overhead for support and maintenance. A centralized repository for data and analysis functionality also increases collaboration among disconnected users. We have experts who can help you implement this type of technology. Learn more >
