Easy Analytics Big Data? Key Benefits:

• Save time by running processes in parallel

• Run processes in the background in ENVI

• Take advantage of beefy machines and modern hardware

• Easily distribute processing to local servers with common data access

• No programming required!

Common data store for distributed processing

Anyone with ENVI 5.6 will be able to access ENVI Server at

no additional cost

ENVI is a client for ENVI Server, meaning we can connect to

machines used for dedicated processing

Why should I care about ENVI Server in SARscape?

Save time by running processes in parallel

Operational Processing with SARscape and ENVI ServerSARscape 5.6 supports ENVI Server to run processing remotely or in the background of ENVI• Save time by running processes in parallel• Bulk processing in the background • Take advantage of powerful network resources• Distribute processing to local servers

with common data access• No programming required!

ENVI ENVI Server

Additional Additional ENVI Server

ENVI 5.6 ships with one ENVI Server and SARscape 5.6 with one background process at no additional cost!

Distributed processing needs a common data store

Add additional ENVI Servers to scale up the number of concurrent processes you can run
