About BJ_FEATURE.h5

[ZJ726]

Hello, I have a question about the original data. In the grid feature data 'BJ_FEATURE.h5', each dimension of the feature value of 989 dimensions corresponds to what features, and 989 is not equal to 940 ‘BJ_POI’ + 47 ‘BJ_ROAD’, why?

Or if you can, could you share the 'BJ_FEATURE.h5' file before it was embedded?

Thank you very much and look forward to your reply!
