How frequently do satellite images update on Google Earth for accuracy?

Satellite Imaging Update Cycle

Google Earth relies on a combination of satellite imagery providers, including DigitalGlobe, Planet Labs, and the US Geological Survey (USGS). The frequency of updates varies depending on the provider and the location. For high-resolution imagery, DigitalGlobe typically updates its imagery every 30-90 days, while Planet Labs updates its imagery every 1-3 days. However, not all areas receive high-resolution updates as frequently, and medium-resolution imagery may be available less often.

Historical Imagery and Hunting Scouting

When scouting for hunting, historical imagery can be valuable for identifying changes in terrain features, such as the formation of funnels or the location of bedding areas. Google Earth offers a range of historical imagery options, including images from the 1940s to the present. By comparing historical imagery with current imagery, hunters can gain insights into changes in the terrain and identify potential hunting areas. For example, a funnel that formed in the 1990s may have been used by deer for years, and historical imagery can help hunters identify this funnel and plan their strategy accordingly.

Using Satellite Imagery for Hunting

Satellite imagery can be used to identify a range of terrain features that are relevant to hunting, including funnels, bedding areas, and food sources. By examining the imagery in detail, hunters can identify areas where deer are likely to congregate, and plan their hunting strategy accordingly. For example, a funnel that forms where a ridge meets a valley may be used by deer to move through the area, and satellite imagery can help hunters identify this funnel and plan their hunt accordingly. By combining satellite imagery with field observations, hunters can gain a more complete understanding of the terrain and increase their chances of success.
