Can AI Super-Resolution Replace High-Resolution Satellite Imagery?
AI super-resolution can make satellite imagery look sharper and, in some validated workflows, improve the information extracted from it. But it does not automatically turn a low-resolution observation into the equivalent of a native high-resolution image. Whether it can replace a new imagery purchase depends on the task: a background map, a land-cover classification, a…

Why Don’t Satellite Images Line Up with Your GIS Data?
A new satellite image arrives, but roads sit slightly beside their mapped centerlines, building roofs extend beyond existing footprints, and a utility corridor appears to have shifted. Before moving any GIS features, check how both datasets were positioned. A sharper or newer image does not automatically provide a more accurate ground reference. Misalignment can come…

How to Check Historical Tree Cover Before Planting
Checking whether trees existed on a plot before planting requires more than searching a forest-loss map. A useful assessment connects each plot boundary to its planting date, examines evidence from the relevant historical period, and records what the available data can—and cannot—establish. Satellite archives can help screen large numbers of plots, but missing loss records…

Can Satellite Imagery Detect Selective Logging?
Satellite imagery can detect some selective logging, particularly when tree removal creates visible canopy gaps, new access routes or repeated changes in the radar signal. However, detecting a large clear-cut is a different task from identifying scattered tree removal beneath a mostly intact canopy. The reliability of the result depends on the disturbance footprint, forest…

How to Monitor Mining Expansion Using Multi-Temporal Satellite Imagery
Multi-temporal satellite imagery can reveal where a mine’s surface footprint is expanding, which facilities are changing, and how surrounding land is being affected. Reliable monitoring, however, requires more than placing two images side by side. The images must be comparable, the changes must be linked to specific mine features, and the findings must be checked…

Satellite Revisit Time vs. Actual Monitoring Frequency
A satellite may be able to revisit your site every few days, yet the interval between usable images can be much longer. Clouds, acquisition schedules, viewing conditions and delivery requirements all affect when a new observation becomes useful. For monitoring projects, the key question is not simply how often a satellite can see the target,…

Can Satellite Imagery Detect Early-Stage Construction?
Satellite imagery can reveal construction activity before a building is completed—and sometimes before its structure appears. Land clearing, exposed soil and expanding work areas can provide early signals. But reliably identifying a small foundation or building extension requires much finer imagery than detecting a large construction site. The result depends on the size of the…

From Imaging to Intelligence: How Smart Remote-Sensing Satellites Are Changing the Market
Several smart remote-sensing satellites have recently been launched in China and other countries, entering a rapidly expanding applications market and attracting growing industry attention. But what does it mean for a remote-sensing satellite to become “smart”? What benefits could onboard intelligence provide, and how might it help satellite operators reach new markets and deliver services…

Russian Satellite Imagery Reportedly Supports Iranian Targeting of U.S. Bases
Russian Earth observation satellites are providing imagery to Iranian military forces to support targeting of U.S. and allied installations across the Middle East, according to defense intelligence assessments reported on September 17, 2026. The reported cooperation involves synthetic aperture radar and high-resolution optical imagery used to refine information on fixed military sites, air-defense positions and…

Pinglu Canal Officially Opens to Shipping: Satellite Images Capture China’s Project of the Century
China’s 134.2-kilometer Pinglu Canal officially opened to navigation on September 16, 2026, creating a direct waterway between the Xijiang River system and the Beibu Gulf. Satellite imagery released by the China Centre for Resources Satellite Data and Application provides a corridor-wide view of the RMB 72.7 billion project and records the construction of new channels,…
