The 411 on Spatial Resolution

Every pixel counts.

  • Problem: Limitations of coarse-resolution imagery.
  • Solution: Choose the right resolution to fit your needs.
  • Benefit: Accuracy, quantification, prevention.

Imagery of the best resolution can facilitate the identification of a diseased tree before it falls on utility lines or spotting a shift of a few feet in a hill before a devastating landslide. When it comes to satellite imagery, there are many options available — though not all are suitable for detection and quantification.

Objects can only be identified if they are larger than the spatial resolution offered by the sensor. So if a sensor with 100-meter resolution is being used to capture imagery, a pipeline leak in its infancy wouldn’t be detected — unless it was the size of a football field or larger! Medium resolutions like 50- and 25-meters, though finer than 100-meters, present at best a vague impression of what’s really on the surface.

In the case of a leak, even if 25-meter resolution imagery captures it, that doesn’t mean it will effectively lead you to the leak’s source. Your organization is paying for incomplete answers and more questions.

Now consider the following image capture of methane emissions, comparing the spatial resolution of others and that of the data we use.

The U.S. government limits the high-resolution shortwave imagery we use for methane measurement to greater than 3.7-meters. This is sufficient to facilitate our algorithms in producing results specific enough to support quantification and location with specificity. All the answers you’re looking for are clear: location, source, flow rate, and concentration.

All of our non-methane services employ sensors with resolutions from 46- to 30-centimeters — about the size of your dinner plate. Imagine what you could see with that (the resolution, not your dinner plate)!
