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 >

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...

App Update Check - Coming soon in IDL 8.6 and ENVI 5.4

Jim Pendleton

First, a dose of nostalgia.

In the early days of commercial IDL, new drops of the application occurred when new features were added and as bugs were fixed for important customers. It was not unusual for there to be a couple different releases per month, a release cycle concept not dissimilar to that of most of today's smart phone apps.

The new releases were signaled through an update to a README-type of text file that was available on a node on a computer network called DECNET, shared by many universities and national labs in the days before the internet as we know it today.

At the organization where I worked, I had a nightly batch job that would alert me to the availability of a new version of IDL. It was a highlight of my week when new features appeared in IDL. Yes, I had that sort of a life back then. Frequent updates, from a customer point of view, kept the buzz alive with the products.  

Here we are about 30 years later and this functionality to check for updates is now built into the upcoming releases of both IDL 8.6 and ENVI 5.4. By default, IDL will check once a week automatically for updates when a new session is started.

Additionally, with the click of a single "Help/Check for Updates..." menu button in the IDL Workbench or from the ENVI UI, you can ensure that you, too, are enjoying the freshest and best we have to offer.

If your version is current, you will receive a dialog assuring you all is well.

To check that your ENVI version is current, find the menu item in the main application user interface.

You will need an internet connection to the commercial world for the status check to complete successfully.

Extra "80s-throwback" credit if you use a packet sniffer to find the syntax of the request and write a script that will automatically launch a WGET query each time you start a new IDL session.

Does this new feature signal a return to more frequent application updates? Have we gone back to the future? Only time will tell.
