Japan region missing subset of 133002112 (appears to be 13300211212) #116

Hello,

I tried downloading data for Tokyo and noticed that the following quadkey is missing from both the geojsonl downloads and the planetary computer:

13300211212

As the other 15/16 quadkeys from level 11 contain data, my assumption here is that there should be some results.

As these are found is there a best practice for creating issues and being notified of potential updates to those particular quad keys?

This issue seems to happen for many other parts. There are a lot of quadkeys in the dataset csv, that can't be found in the buildings-coverage.geojson

Try to cut off the last 1-3 chars from the key.

Thanks for the info. To be sure I am not missing anything, I tried using the sample code here:

https://planetarycomputer.microsoft.com/dataset/ms-buildings#Example-Notebook

to use either STAC or Delta to download and transform the data to a geojson file. When I tried using Delta and setting a different zoom level than 9, I got no results from my search. When I used 9 I retrieved the same data where the content of 13300211212 was missing.

Is there another way I should be querying this?
