What is ESE?

ENVI Services Engine:
Image and Data Analytics for the Cloud and Enterprise
Cloud and/or enterprise-based processing engine which leverages the power of IDL, ENVI, and ENVI
LiDAR analytics to create products for consumption by desktop, thin, or mobile clients. Because ESE
analytics are performed server-side, these applications can retrieve, process, and publish data to the cloud
without ever running any data I/O or processing on the client computer or device.
A client can be anything that speaks HTTP, such as a webpage, IDL, C++, etc...
This allows developers to write applications in the language of their choice, then use ESE to do analytics
using IDL, and the ENVI and ENVI LiDAR Application Programming Interface (API).
Because it is deployed on a server, it is always "on", giving you on-demand distributed processing over an
enterprise network or on the web.

ENVI Services Engine Architecture
Application developer
builds customized
application, leveraging
the power of ENVI image
analysis algorithms
The
developed
services are
deployed to a
server
architecture
in the cloud
Results are delivered
back from the Engine
and can be saved out,
utilized in further
analysis, or …
displayed in a
variety of web,
desktop, or mobile
clients.
HTTP REST requests are
made from middleware to
server
ENVI Services Engine
executes the application
• Application developer builds custom applications
• Developed services are deployed to a server architecture
• ENVI Services Engine executes the application
• Results are delivered back to ENVI Services Engine for further analysis, or…
• Results can be displayed on a desktop, across an enterprise, or on any device that has access to
the world wide web
