Yes, it’s what I want now. At present, I just want to repeat the experiment. (By the way, are there any easy-to-use high resolutuon remote-sensing image?)

When I tried to create the drone image tiles the OpenAerialMap API, the robosat.tool download just returned too many “Warning: Tile(x=857247, y=430855, z=20) failed, skipping”. After I debuged the program, it showed “{“message”:”Not Authorized - Invalid Token”}”. But I did copy the “tms” property from the “http ‘https://api.openaerialmap.org/meta?bbox=114.159102840124,30.3833619895642,114.637039919757,30.6950619601414’” request. And I choosed “

to download the tiles. Similarly, I tried to repeat your work in the diary. Sadly I didn’t get the tiles either. Did my network have some problem or other reasons?

Sorry to trouble you again. Similarly I tried to prepare tiles from Tiff Image downloaded at OpenAerialMap. The tiling speed was about 60tile/s, and the speed would go down after it operate several hours. it would take a lot of time to tile my study area. I’d like to know your tiling speed, and is there any lib which could accelerate the tiling speed or I must write my own code.

Thank you for your detailed introduction to the RoboSat pipeline, but there’s still some confusing places for me. Could you please tell me if the online web site which you used to fetch a bounding box is available now? And May I take it that the bounding box has nothing to do with the final process once your bounding box covers the study areas?
