Mapping Earthquake Deformation in Taiwan With ENVI

Mapping Earthquake Deformation in Taiwan With ENVI

12/15/2025

Unlocking Critical Insights With ENVI® Tools Taiwan sits at the junction of major tectonic plates and regularly experiences powerful earthquakes. Understanding how the ground moves during these events is essential for disaster preparedness, public safety, and building community resilience. But traditional approaches like field... 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

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...

A cool visualization with Object Graphics

Anonym

Peter Delamere, a research associate at the Laboratory for Atmospheric and Space Physics (LASP) at CU-Boulder, made this visualization of plasma flow around Io, with Jupiter in the background, using IDL Object Graphics:

Plasma flow around Io

Here's Dr. Delamere's description of the visualization:

The figure illustrates the complex electrodynamic interaction of Jupiter's innermost Galilean satellite, Io, with Jupiter's magnetosphere. The moon is constantly bombarded by plasma (ionized sulfur and oxygen) flowing by at roughly 57 km/s (flow lines color coded according to flow speed), generating a few mega amps of current flowing through its atmosphere and coupling the moon to Jupiter's atmosphere. The isosurfaces show high plasma temperatures on the flanks (red), high plasma density in the equatorial region and the downstream wake (blue) due to ionization of Io's atmosphere, and magnetic field perturbations associated with the electrodynamic interaction (green).

Thanks, Peter! If you've made a cool visualization with IDL that you'd like to share, please send it to me and I'll post it.
