Year limit for sentinel-2 data in generating timelapse gif?

[keqisarah]

I have tried the "geemap.sentinel2_timelapse" in my study area, time period is set to the same as the example, from 2017 to 2023. However, there are error messages shown as the figure. My study area is smaller than the example (-76.77169893823239, 39.19472525990652, -76.47232149682614, 39.429542585647454).

May i ask what is the reason of the error? and I tried the change the year from 2023 to 2020, I can get the gif file, why my study area is small but can't generate the timelapse file till 2023. Meanwhile, I remember for Landsat data, we can even generate files within longer than 40 years.

But when I tried to limit the month periods only in summer, like from April to Oct., then the gif can be generated till 2023. May I ask what is the year limit? Or should I ask what is the limit of total data frame numbers to generate a gif?

Sentinel-2 has a 10-m resolution, while Landsat is 30-m resolution. The number of pixels being processed is at least 9 times more than Landsat. The memory error is not surprising. You either need to use a smaller area or shorter time span to avoid the error.

Thank you for the prompt reply, but i think the revisit frequency is a more critical feature. Since the sentinel-2 data could be every 5-day a frame while Landsat could be every 16-day.

Another clue is the solution when I limited the months only during the summer (with a file of 1.72 MB). And my study area only covers several communities, typically very very small compared to the code example, so I assume there are frame number limits to generate the gif?

No, there is no limit on the number of frames. The real issue is the number of images, file sizes, and pixels being involved in the computation. Even though the output GIF file is small, there could be a lot of images being used to generate the GIF.

Got it, thank you for the detailed information
