I've been using the Google Earth Engine API in an attempt to access Landsat 8 imagery for land use change detection in the South China Sea. Initial investigations suggest that Google may have removed imagery of this area from their collection, as when I run the code in the link below all images are clipped to the surrounding mainland coastline of each country.
Having checked the following, https://earthexplorer.usgs.gov/ I can confirm that suitable Landsat 8 imagery does exist for this ROI, so my question is:
Is there any documentation where Google specifies why this has been excluded from their Landsat 8 collection? Or have a made a mistake in the code above that somehow excludes the imagery I am looking for?
