Yeah, I hear you. I chose spatial tiles for the Solr patch, but spatial grid would work too. Or map tiles/map grids. That anchors it into the spatial world, since we're calling Lucene's spatial contrib/spatial and Solr's Solr Spatial. > > On Mon, Dec 28, 2009 at 1:16 PM, Grant Ingersoll <gsing...@apache.org>wrote: > >> >> On Dec 28, 2009, at 3:51 PM, patrick o'leary wrote: >> >>> So Grant here's the deal behind the name. >>> Cartesian because it's a simple x.y coordinate system >>> Tier because there are multiple tiers, levels of resolution. >>> >>> If you look at it closer: >>> - To programmers there's a quadtree implementation >>> - To web users who use maps these are grids / tiles. >>> - To GIS experts this is a form of multi-resolution raster-ing. >>> - To astrophysicists these are tiers. >>> - To the MS folks I've talked to they have quad something or other. >>> - To math folks Cartesian levels makes sense. >>> >>> Can't make all the people happy all the time, >> >> 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.

I'd be fine with SpatialGridField as well (GridField seems a bit too >> generic).
