Monitoring Illegal Mining in the Amazon: Turning Persistent Data Into Actionable Insight

Monitoring Illegal Mining in the Amazon: Turning Persistent Data Into Actionable Insight

5/28/2026

Illegal mining over decades has constituted one of the most persistent and complex socio-environmental problems in the Brazilian Amazon. In recent years, with the increasingly intensive use of mechanized extraction, the associated environmental impacts—such as deforestation, intense soil disturbance, river siltation, and mercury...

From Answers to Action: Why ENVI and IDL Agents Go Beyond General AI

From Answers to Action: Why ENVI and IDL Agents Go Beyond General AI

4/20/2026

As generative AI tools like Claude and Gemini continue to gain traction, many organizations are asking the same question: Can general purpose AI actually support real geospatial workflows, or does it stop at surface-level answers? That question was front and center in our recent webinar, Meet Your New Partners in Science: ENVI... Read More >

Comparing Amplitude and Coherence Time Series With ICEYE US GTR Data and ENVI SARscape

12/3/2025

Large commercial SAR satellite constellations have opened a new era for persistent Earth monitoring, giving analysts the ability to move beyond simple two-image comparisons into robust time series analysis. By acquiring SAR data with near-identical geometry every 24 hours, Ground Track Repeat (GTR) missions minimize geometric decorrelation,... Read More >

Empowering D&I Analysts to Maximize the Value of SAR

Empowering D&I Analysts to Maximize the Value of SAR

12/1/2025

Defense and intelligence (D&I) analysts rely on high-resolution imagery with frequent revisit times to effectively monitor operational areas. While optical imagery is valuable, it faces limitations from cloud cover, smoke, and in some cases, infrequent revisit times. These challenges can hinder timely and accurate data collection and...

ENVI Tasks make ENVI even smarter

Anonym

In my last blog, I wrote about a few ways ENVI Task is making it easier for developers to quickly deploy functional image processing workflows and batch routines. This week I'd like to discuss how ENVI Tasks are making it easier to build workflows that are procedurally robust.

When I say procedurally robust, I'm talking about the correct order of image processing operations to obtain an accurate and repeatable result. For example, is it best to resample (an interpolation step) a raster before or after the primary analytic is applied? What about sub-setting (reducing the extent) of a raster - should that be done before or after the task is run? Get the order correct and instill confidence in the answer your customer demands. Get it wrong and you might be misrepresenting your results.

We are building properties into each ENVI Task object that help a client or programmer understand the impact of these decisions. In this way, we like to say we are making ENVI smarter.

You can check outthese properties in our online help system for ENVI Task: http://www.exelisvis.com/docs/ENVITask.html Look under COMMUTE_ON_DOWNSAMPLE and COMMUTE_ON_SUBSET for more details.

Can you think of additional properties that we should carry with the task that will make ENVI smarter? If so, let us know in the comments below.
