Bounding Boxes for World Countries (Berkeley GADM)

Tuesday, June 23rd, 2009

[Editor's note: Knowing the longitude-latitude (latLng) bounding box of a feature gives us a clue as to what map scale or zoom level is required to fit the feature into our display area and thus what base map scale set to draw from. While this image does not provide actual coordinates, it visually establishes what such bounding boxes look like (further refinements can be had with respect to crossing the 180° meridian, note New Zealand). ]

Here is a map of all countries and their bounding boxes (when using a lat/long “projection”), highlighting those countries that cross the international date line, and for which these bounding boxes make little sense (this map is provided for diversion only).

Effective immediately, the address for the suburban split-level the Beyersdorfers have occupied for 43 years is no longer 6211 Wedgewood Rd. That address now belongs to one of the two unbuilt houses next door. The Beyersdorfer house has been bumped to 6213.

It was, the letter said, simply a matter of public safety. The numbering system is designed to help emergency vehicle drivers easily find addresses, the letter said, and a sequential system is the best way to do that.

Or, as a county planning official told Anne Beyersdorfer one recent day as she questioned the decision, “sometimes you just don’t have any options.” And no, the county doesn’t allow 6209 1/2 or 6209A and 6209B.

“That’s just rude,” Beyersdorfer said. “How can there be no options?”
