Up-to-date high resolution imagery is quite expensive. Most of Google maps imagery is generated from an older database of images. Businesses like Maxar (formerly Digital Globe) that provide Earth imagery will sell a database of old out-of-date imagery for much cheaper. But more recent imagery is much more expensive because it is much more valuable. These companies will often provide free images that are up to date to help with disaster and recovery efforts but that doesn't mean it has been put in to Google maps yet, a lot of it just still an old database of imagery.
In Summary:
- Old out-of-date imagery: $
- Newer up-to-date imagery that has been captured: $$$
- Tasking a spacecraft to request image of a specific area: $$$$
- boringg 5y agoLike all data -- new and high def data costs a lot more than something a couple years old. Data ages out.
- ideashower 5y agorandom question, but where would one acquire old out of date imagery of this part of the world? For example, I know through Google Earth's timelapse feature that Gaza has been consistently scanned by satellites over the last 3 or so decades. But the images on Google Earth's timelapse feature are of very very low quality. But viewing the timelapse is evidence enough that this information is out there.
