Providing a global info about the ore in ALL systems makes no sense because there is no way to know what ore and grade of it are in a system unless that system is controlled by a faction/player corp, which is WHY we don’t know anything about the ore in the rest of the systems of the galaxy that are not part of the game, let alone the entire galaxy, let alone other galaxies.
So it would make much more sense if the info for the ore in the map is “filtered” based on the standings of the character with the factions/corporatoin that sovereigns the system, if the standing are above a threshold - include them in the data that is send to the player. The only exception of this rule would be system that are tagged as being involved in faction warfare, I have never flown in those so my guess is they are neither of each but both the factions that war in them could provide info for the pilots, also systems that are under pirate invasion so the pirates would provide info to the respective high standing pilots! So in my case I should get no info from the systems controlled by the Serpentis, Sansha, Raiders and Angles as my ratings with them are way bellow -5.0.
