Right, but as far as I can tell (and I've only done, say an hour of research), I can't find anyone who calls them Cartesian Tiers other than us. Personally, I think web users are the largest group (after all, aren't we all web users?) out there and therefore will be the most familiar with either grid or tile. FWIW, I have tentatively called the Solr FieldType to support this "SpatialTileField" as in it represents a tile in the spatial sense. I'd be fine with SpatialGridField as well (GridField seems a bit too generic).
