    Ganz ehrlich, der User u/Linkerbaan ist mir schon häufig aufgefallen. Er ist einer der größten Hamas-Propagandisten auf Lemmy, und hauptsächlich auf den beiden großen worldnews communities unterwegs.

    Meiner Meinung nach hat der einen Permabann verdient. Wegen solchen Leuten trete ich aus Communities aus, ohne Moderation ist schlicht nicht dagegen anzukommen.

    Diesen speziellen Fall hier hab ich mir jetzt gar nicht erst angeschaut. Hast du die Mods von !europe@feddit.de mal persönlich angeschrieben und gefragt? Wenn Sie auf reports nicht reagieren, haben sie wohl leider eine andere Meinung als du, so ist das auf Lemmy…














  • For optical images you want Sentinel-2 (EU) with 10m Resolution or Landsat 8 (NASA) with 30 m resolution. You can use the Copernicus Open Data Hub and the The USGS earth explorer for download, they offer graphic inferfaces where one can select an area of interest or upload shapefiles.

    There are many more data sources, specialized software and/or APIs for Python for batch downloading etc.

    When you have downloaded the data, you can use different programs for visualizing and georeferencing the images such as QGIS.

    Keep in mind the work with satellite remote sensing data is not trivial and usually requires many postprocessing steps. If you just want to explore the earth surface I would recommend to look for local ortho images from aerial photography. Depending on where you live, this data will be made available for download and/or exploration via a web mapping service (WMS). It is much more detailed and may be more interesting you, and a bit less complicated than satellite data.

    Just to be complete as you asked for satellite data in general: Of course there is much more available than just RGB channels. You can get more band e.g. Near Infrared from Sentinel-2, or cool stuff like RADAR from Sentinel-1, LIDAR from GEDI etc. There are plenty of satellite missions for all your desires.

    For anyone who wants to dive more into these topics, search for satellite remote sensing. You can also find many tutorials for processing this data e.g. using Python or R.
