How big is this park? NYC has the answer or GIS mischief?

I think they still don’t know.

>The aim was to learn the size of each of the city’s 1,700 parks down to the thousandth of an acre, said Joshua Laird

Precise to 0.001 acre?

I want to meet the surveyor that will certify an 1200 acre survey to 0.001 acre. 🙂

Even more amazing, they are using GIS to determine area to 0.001!

No certification required!

(897.62 to be precise)

Flushing Meadows was only listed to 0.01 ac. Looks like some folks need a refresher on Significant Figures.

My browser says the title is 'Surveying Effort Alters Sizes..."

And... They are the big push for a national system with all our reproducible bearings all tied together.

0.001 acres!! That is amateur hour.

I have seen many folks around here who are surveying large acreage tracts with such precision as to justify reporting it out to 0.0001 acre.

“There is a certain artistry behind the old hand-drawn maps, and now everything is done on computer,” he said. “It’s a trade-off between beauty and accuracy. But numbers are important.”

Is this clown serious? Doesn't New York have any standards? You want real numbers get it surveyed.

Ah-HA....it's the computer that changed the acreage. Hey I can get those acres down to 5 places behind the decimal!

"lost 0.049 acres" ... probably due to global warming. Things do shrink in the dryer!
