I attempted to make a Timeseries gif using Landsat data. I used images of Howth and Bull Island in Dublin from 1980 to 2023. The first attempt was well 👇

Problem 1: I cropped the images but didn't realise positions would change depending on the image.

Problem 2: clouds!!!

Problem 3: what's with the black lines on some of the images?

@conorosully did you do these by hand (your programming) or using a service? I think EObrowser from SentinelHub has some Lansat (but possibly not to 1980).

@lavergnetho I'm trying to do it using only code. I want to be able to apply it to any location with minimal manual work.

I'm using this python package to access the data: https://github.com/yannforget/landsatxplore

It is based on the ESGS M2M API: https://m2m.cr.usgs.gov/api/docs/json/

It allows you to access landsat 5,7,8 and 9 data using Python.

@conorosully @lavergnetho Also, consider getting a Microsoft Planetary Computer account. Although Google's equivalent has been around longer, #PlanetaryComputer allows you to do these things easily with standard Python tools and libraries (eg #xarray )
