Dove trovare immagini satellitari storiche?
Google Maps does not provide imagery from as far back as 1990; its historical data generally begins in 2007 for Street View, and satellite/aerial imagery availability from before the early 2000s is extremely limited or nonexistent. However, you can view changes from the earliest Google-captured years (such as 2007) up to the present, including projections into 2025, using different Google tools [2] [3] [1].
Key points:
-
Google Maps Street View:
- Street View historical imagery is available mostly from 2007 onwards, depending on the location. There is no Street View imagery from 1990, as Google Maps and its related imaging technology did not exist at that time [3] [1].
- To view historical images: drop a pin on a location in Google Maps, enter Street View, then look for the date at the bottom and select "See more dates" to browse available years for that spot. The range of years you can see depends on when Google made captures in that area [1] [3].
-
Google Earth Pro:
- For broader satellite/aerial imagery comparisons over time, use the Historical Imagery feature. The oldest satellite images vary by location; some densely populated or important regions may have aerial photos from the early 2000s, but not from 1990 [2] [4].
- In Google Earth, you click the clock icon to bring up a timeline and select available years to view map changes. Most historical data still starts no earlier than the late 1990s or early 2000s, barring inclusion of old, low-res black-and-white satellite data [2] [4].
-
Google Earth Engine Timelapse:
- This tool provides global annual satellite snapshots, beginning as early as 1984 with Landsat data. However, these images are limited in resolution and not suitable for street-level or city block detail [2] [7].
-
Current and Future (2025) Data:
- Google Maps, Street View, and associated apps continue to update, with new versions and map imagery usually being only a few months out-of-date (or, in case of some satellite imagery, up to 1–2 years behind real time) [5].
In summary: While you can view some areas globally from as early as 1984 via satellite timelapse, and Street View imagery from 2007 onward for many locations, there is no way to see precise Google Maps imagery from 1990. For changes between the earliest available date and 2025, use the historical imagery timelines in Google Maps Street View, Google Earth, or Google Earth Engine Timelapse [1] [2] [4] [3].
If you are seeking historical maps from 1990 specifically, you would need to consult national mapping archives or historical atlases, as they are not available within Google Maps or Google Earth.
