What is the difference of Spatial_matrix.csv and Spatial_matrix_rook.csv?

[rabbit200]

Congratulations on the publication of your paper. It is really a great job and is very enlightening to me.

After debugging your code, I have some trouble understanding the difference of the Spatial_matrix.csv and Spatial_matrix_rook.csv .

I guess Spatial_matrix.csv means 0/1 adjacent matrix generated by (OD) flow, while Spatial_matrix_rook.csv means geographic 0/1 adjacency matrix generated by Rook-type contiguity relationship.

Am I right ?

Looking forward to your reply, thank you sincerely !

Thanks for your interest! Yes, you are right! The two files are used to describe different spatial adjacency relationships between nodes.

Hi! As you described in readme file, Spatial_matrix.csv is the adjacency matrix generated based on the geographic adjacency relationship.

There are various geographic adjacency relationships in TIGER/Line Shapefiles, common edge(Rook), common corner(Queen), and so on.

I'm wondering which type of geographic adjacency relationship for constructing Spatial_matrix.csv

Yes, good point! You can use either spatial relation to construct the spatial_matrix.csv file. It depends on whether you want to include geographic neighbors that include common vertices in addition to common edges/boundaries.
