Earth imaging basics: spatial resolution.

Spatial resolution is the core way in which we benchmark satellite imagery.

What spatial resolution do you require? That depends on what you need to see.

RADARSAT-2 Automated Change Detection On GBDX: How It Works

The RADARSAT-2 satellite enables new capabilities that complement optical satellite data such as broad area change alerting and all season/weather target monitoring. The RADARSAT-2 mission provides a unique imaging mode called ExtraFine which has 5m resolution and a scene size of 125 km x 135 km so it can provide complete overlapping coverage, even at [...]

Finding Oil Tanks With GBDX Image-filtering Algorithms

Estimating oil reserves from high-resolution satellite imagery has become rather fashionable in our budding geospatial-analytics-from-space industry. We have developed a geospatial image analysis and processing software suite available to GBDX subscribers, which uses state of the art hierarchical image representation structures for the efficient organization, access and retrieval of the image information content.
