Description

I am missing important information on the mentioned "DE-9IM intersection matrix" at https://docs.djangoproject.com/en/4.0/ref/contrib/gis/geos/#spatial-predicate-methods. Nobody knows what T*FF*, *TFF*, *TFF*, or T*FF* mean and where to get this information. I suggest to add information about this matrix or where to find a definition of it.

I don't agree, folks working with spatial relations of geometries are quite often aware of DE-9IM.

I suggest to add information about this matrix or where to find a definition of it.

Adding a reference to the Wiki page should be enough. Would you like to prepare a patch?

I think it wouldn't hurt to add a link to some reference documentation like the mentioned Wiki page.
