Satellite imagery is revolutionizing the detection of illegal construction. By combining high-resolution images with building registry data, tools like OnGeo Intelligence enable municipalities to identify unpermitted structures, recover lost tax revenue, and address safety hazards. Learn how this technology works and how you can use it to prove unauthorized building activities.

Maxar’s DigitalGlobe, in partnership with PSMA Australia, has achieved a groundbreaking milestone in geospatial mapping—Geoscape, the first high-resolution dataset covering the entire Australian continent. By 2018, the project had mapped 7.6 million square kilometers and analyzed over 15 million buildings, revolutionizing data-driven decision-making for businesses, governments, and researchers.

Satellite images are rich sources of information, but unlocking their full potential requires the right approach. This guide covers essential techniques for interpreting satellite imagery, including understanding image scale, recognizing patterns and textures, analyzing colors and shadows, and applying contextual knowledge.

Satellites like Landsat 8 photograph Earth every 16 days, Sentinel-2 every 5 days, and Planet Dove every day. However, clouds can ruin an image, and commercial providers like Maxar or Airbus often take pictures on demand. Learn how this process works and who has the most data!

How off-nadir imaging works: Satellites are equipped with sensors that can adjust their viewing angles to capture images of areas not directly beneath them . This capability allows for increased revisit rates, enabling satellites to image specific locations more frequently without waiting for a direct overpass . By tilting their sensors, satellites can also acquire stereoscopic images from different angles, which are useful for creating 3D models of the Earth's surface.

Adding Satellite Basemaps in QGIS QGIS makes it seamless to incorporate satellite basemaps—often referred to as "basemaps QGIS" in the geospatial community—using the XYZ Tiles feature. This tool connects you to online tile services from leading providers, delivering high-quality imagery at various zoom levels. Follow these steps to enrich your project with satellite basemaps:

A dramatic fireball lit up the skies over Northern Europe as debris from a SpaceX Falcon 9 rocket made an uncontrolled reentry over Poland. The incident raised concerns about space debris and was closely monitored by European space agencies.

The CORONA program was the first successful reconnaissance satellite initiative, providing the U.S. with crucial intelligence during the Cold War. Utilizing film-return capsules and daring mid-air recoveries, it marked a pivotal advancement in espionage technology.

The latest satellite images reveal the scale of Mount Etna’s eruption on February 16–17, 2025. This article analyzes terrain changes, the eruption’s impact on the environment and settlements, and the importance of satellite data in monitoring volcanic activity. Discover how modern technology helps predict hazards and minimize the effects of natural disasters. Check out the full analysis based on satellite imagery!
