You could use something like https://github.com/mapbox/untiler to stitch them back together again - but I wonder if it would be more useful to run a local tileserver and view them on a proper map instead?
Hmm, I've never run a local tileserver (coming from a deep learning background) but that sounds promising. I am investigating now but if you have any resources on how to get a local tileserver set up it would be much appreciated. Thank you!
To avoid the xy problem - what do you want to do with the larger images? If it's for visualization or further post-processing just serve your slippy map directory via HTTP e.g. via
python3 -m http.server
and then point any map framework to this endpoint, e.g. using Mapbox GL JS check out the compare map we provide
This will give you an interactive map loading tiles on demand
You can do this for the aerial imagery, the probability files, and the mask files.
Thanks, I do want to just view the aerial imagery, the masks, and the probability files so I think the tileserver is the way to go. I have successfully run the:
python3 -m http.server
And I can navigate to the corresponding directory in my web browser but I'm unclear as to what you mean by "point any map framework to this endpoint" and how to make use of the html script you linked. My apologies if this seems obtuse, this is my first time doing this.
index.html
similar to the template inUse e.g. Mapbox GL JS (see template) to visualize Slippy Map raster tiles
Point a raster layer to localhost, port (this is where your http server serves your tiles).
If you put the index.html
into your slippy map dir, you can use the simple Python HTTP server to serve both your index.html
and your slippy map tiles.
Think this is resolved - please reopen if there are further questions!
sorry for disturb. I try to serve my slippy map tiles generated by running this script, but I failed to do it. I cannot understand this:
just serve your slippy map directory via HTTP , and then point any map framework to this endpoint
below are what I tried:

/home/tiandeyu/robosat-taipei/robosat-hainan/tiles
this is my tile folders, the image format is webp, and my map.html here:

open the python3 http server in port 8887 and I can check the dir and files in my browser

Then I try to visualize the slippy map tiles with Mapbox GL JS API, but I can not find my tiles in the local address:http://127.0.0.1:8887/map.html#17 here is the contents of the map.html:

Hello, I'm wondering how, after you've built the training data folders for the masks and images, you can compile the slippy map tiles into a single (or at least many larger) images. As a check, I'd like to visually inspect the imagery that I've downloaded along with the corresponding classification masks. From my review of the Slippy Map format, given the format " /zoom/x/y.png", I should just be able to join the tiles in a grid fashion using the x and y values. Am I mistaken here?
I extracted a rectangular region, yet I find that the "x" subdirectories contain often wildly different numbers of tiles. Any suggestions?
Thanks!
