Historic Landsat imagery on Google Earth Pro

by matthewfloyd1 » Tue Aug 23, 2022 7:50 am America/New_York

Hello,

I'm working on a project that tracks change through time in Maldivian marine habitats. As such, I'm interested in acquiring satellite imagery from as far back in time as possible. I've been looking through the Google Earth Pro historic satellite imagery which purports to go back to 1985 - see attached file - the metadata shows that this image is acquired from 12.31.1985 and the data source is Landsat/ Copernicus.

I have tried to look for Landsat data from 1985 covering this region however I have been unsuccessful using the USGS earth explorer web application and through Google Earth Engine.

Can someone offer advice on this? Why am I unable to find the data displayed on Google Earth Pro from the data provider (Landsat/ USGS)? And is there somewhere else I should look to find this data from 1985?

many thanks,
Matt

Hi @matthewfloyd1 I have spoken with the Landsat team and the Landsat catalog has no record of a Landsat scene over this area acquired on December 31, 1985. We are unsure of what is being shown on the map you provided. However, looking in USGS EarthExplorer: https://earthexplorer.usgs.gov/ there are data over the Maldives from select dates between 09/24/1978 and 06/23/1982 that you may be interested in from the "Landsat 1-5 MSS C2 L 1" dataset. If you are interested in those dates, please use USGS EarthExplorer to search for and download the available data.

Thank you very much for looking into this for me. This is very useful.
