★★★★★ – Essential Tools for Remote Sensing and Data Analysis

As a geospatial software developer, I’ve worked with many platforms over the years, and ENVI 6.2 together with IDL 9.2 from NV5 Geospatial have quickly become my go-to tools.

The new ENVI 6.2 features, especially the faster spectral detection algorithms and expanded satellite data support (including BlackSky and Planet’s Tanager), have dramatically improved my workflow efficiency. Processing large hyperspectral datasets is noticeably faster, and the results are more accurate thanks to the new covariance regularization options.

On the programming side, IDL 9.2 is a solid upgrade. The improved FFT performance on ARM-based Macs is a game changer for time-series and spectral analysis, and the language remains one of the best environments for building custom geospatial applications, automation scripts, and data visualization dashboards.

Both tools run smoothly on modern Windows, Linux, and macOS systems, and the stability improvements in these versions are clear. I’ve noticed fewer crashes, better memory handling, and an overall smoother experience.

For any developer, researcher, or analyst working in remote sensing, earth observation, or scientific computing, this release is absolutely worth the upgrade. ENVI 6.2 and IDL 9.2 continue to set the standard in the industry.
