Indeed! I may have to try that one ... it's probably not a moi:bius embedding, but it's worth a try just in case ;-) > "Zero Brattle", although that is in the wrong I suspect it finds it because of text searching in Local Search, not Google Maps address parsing. It also appears to have Cardullos on the wrong side of the street? I've noticed that Lat/Lons for Google street addresses are not the same as for Google Local Search items claiming the same address ... 6 Brattle St comes up at the same point as TeaLuxe icon on "Zero Brattle" did, but the Cardullos flag on the "Zero Brattle" search is up at JFK & Brattle -- on the JFK side not the COOP side of the street. Do the odd-even sides of street swap when Brattle St dog-legs at Brattle Square? One of the odder geographical brandings is the two adjacent buildings, 10 Post Office Square and Ten Post Office Square. Their lobbies are interconnected, but they're considered separate properties and addresses. Google doesn't do Ten, only 10. In fact, www.google.com offers maps of 10 Post Office Square if you search for Ten Post Office Square. Well, it'll get you within a hundred feet, that's not too bad ... but won't tell you the crucial fact that there really *are* two buildings 10 & Ten POSq, and also there really is a second (although not *twin*) peak on Mt.Kilimanjaro**, Monty Python* not withstanding. [* Monty Python, Season 1, Episode 9, The Ant, An Introduction included the Twin Peaks of Mt Kilimanjaro sketch. Ultimate in-joke is that Kilimanjaro has a subordinate volcanic peak with a broad saddle, and a third minor peak as well. Also in movie "Now for Something Completely Different".] [** Kilimanjaro: http://www.directionsmag.com/images/mapgallery/30_md.jpg Mawensi peak http://www.peakbagger.com/peak.aspx?pid=11203 is a good bit lower, across a wide saddle (called The Sadle) from the main High Camp and peak, less than 7 miles away. http://www.backpackingtheplanet.com/africa/africaPhotoPage.asp?PgNum=8 ] > Geography is hard. Real data of many kinds that real people live with is harder than nice clean math, but yes, Geography is delightfully hard.
