In DAS, the primary satellite imagery you see is sourced from Google, which is updated periodically based on Google's update schedule. The frequency of these updates can vary:
Urban Areas: Typically receive more frequent updates due to higher demand and better data availability.
Rural Areas: Updates may be less frequent, with some regions having imagery that is a few years old.
Average Update Frequency: Google’s satellite imagery generally has an average age of 1-3 years, though this can vary based on region and imagery availability.
Building Layer Updates:
The building layer in DAS is separate from the satellite imagery and is updated quarterly from our data vendors. This ensures a more accurate representation of structures like houses, silos, and sheds.
Why Does Imagery Vary in Age?
Imagery updates depend on factors such as weather conditions, data availability from Google’s vendors, and the priority of certain regions. This means that some areas may show more recent imagery, while others may be older.
