I'm Back, Yet Again

After battling network issues and then some weather issues and spending some time in the mountains with L, I am once more sweating profusely at my keyboard. So what great oddity do I bring forth to celebrate my return? That was a tough question since I seem to have run amok amidst things that pique my interest and curiosity of late.

For example, I read that the recent quake in Japan is estimated to have moved the main island approximately 8 feet eastward. Interesting in and of itself, but that led my mind wondering how property surveyors handle the movement. Up til the introduction of GPS units it would not have make much difference since survey marks were based off the geologic survey markers embedded in the ground. Since the ground moved, the basis mark moved with it and all was fine. But now survey is based increasingly off of precision GPS readings. Those GPS readings are based on satellite positioning, not ground. So the ground moved but the satellite did not.

Picture now the poor Japanese property owner whose neighbor wants to build a fence at the edge of his lot. The deed marks the lot in terms of latitude and longitude. So a surveyor comes out and marks the corners of the neighbors lot from the latitude and longitude via satellite and now discovers the the lot sits 8 feet into our poor owners lot, right through his kitchen. So how is the subsequent slew of anomalies corrected/handled. Inquiring minds want to know!

I'll leave you with one of my favorite Gore Vidal quotes:
Half of the American people have never read a newspaper. Half have never voted for President. One hopes it is the same half.


  1. If only it were the same hal indeed

  2. Very interesting stuff to ponder about :) Good thing we don't own any land in Japan! We just rent :)

  3. The Japanese have an interesting problem there! Here we'd be in the courts for years; hopefully they can do something more reasonable.


You know you want to ... so just do it!!!
