Measurement tool errors at small scale

Received via email:

it seems that both the polygon tool and linear tool have errors at small scales – they only seem to work at or above 1 mile which is why our office was most likely having issues. In summary:

• Columbus Circle appears to be the same amount of square feet as it is square meters. (Measure the circumference of the circle in feet and then switch to meters)
• The linear measuring tool jumps from 1,609 feet to 1 mile (measure a line feature and observe the jump from feet to miles happens at the wrong spot)

Hotfixed in 907c950, which refactors handleMeasurement() in main-map.js.

Confirmed conversions between standard and metric are accurate, and all "upgrades" to larger units are taking place at the appropriate thresholds.

Also confirmed tracing this BBL in staten island measures ~9000sf in area, consistent with the lot area in PLUTO

Measurement tools is working perfectly now. Square Footage is extremely close to the site Survey on file.
