Hi Matt,
1) Trying to find the closest 1 facility of 11,000 points for each of the 900 incidents; but the export would include drive time, not just distance;
2) Yes, it would be OK to do that; that solution is the only thing I've come up with. In Pro, you can generate a Near Table, so I was thinking about sub-setting the 11,000 points to just 900 by picking up the closest (in distance) single facility, and then trying to run the Closest Facilities tool in Pro or AGOL;
3) The points cover the entire U.S., including AK, HI, PR;
4) Just time/distance to each closest facility;
5) experience with Python mostly, some SQL and web programming languages.
