sentinel plug in ship detection script

0 Upvotes

hello guys,

I have been using QGIS sentinel plug in for a while and create a spesific configuration by using custom script of sentinel 2. however when I open it via software it doesnt work well. I cant see any differences with ordinary satellite image and ship detection script. Anyone who use this before? I am sharing relevant link above.

Is there a way to organize point displacement to group points by category instead of having them random like in this screenshot? To make it more like a pie chart? Thanks

Open Question/Issue How do I automatically download Sentinel-2 imagery for an AOI over a long time period ?

2 Upvotes

I'm working on a school remote sensing/ML project and I'm trying to figure out the best way to automatically download satellite imagery.

My goal is:

  1. I have a geographic area/AOI ( a shapefile,list of coordinates)

  2. I want Sentinel-2 imagery

  3. I want to specify a date range

  4. I want to filter by cloud cover ( if possible 0% )

  5. Ideally I want one image every ~15 days (or another fixed interval)

  6. I want the imagery downloaded automatically as GeoTIFFs

  7. I eventually want to use the images in QGIS/Python for land-cover analysis and ML

I've figured out how to download the imagery manually, but I want to automate the data acquisition pipeline.

I've tried using Google Earth Engine and Python, and I found a GitHub project called EEDL(Earth Engine Downloader), but I'm having trouble getting the actual image downloads to work.

For people who have done this in actual projects: what workflow or tool do you use to automatically search for and download Sentinel-2 imagery for an AOI over a long time period?

I'm especially interested in working implementations using Google Earth Engine Python API, STAC, Sentinel Hub, Copernicus Data Space, etc., rather than manually downloading scenes.

If you have a GitHub repo, example project, or tool that does this, I'd really appreciate it.

Does QGIS have a tool to make pie chart clusters like ArcGIS does? Thanks
