[Talk-us-massachusetts] Groton's JONATHAN NUTTING ROAD

[Alan & Ruth Bragg]

Interesting. My question for Massgis is "Jonathan Nutting Road" exists as
and "ACTIVE" address in the Groton "AdvancedAddresses_M115" xls file I
downloaded from
http://massgis.maps.arcgis.com/apps/View/index.html?appid=530eb45188934e23a8703399fd37bf0f
126447097 1094579 1 JONATHAN NUTTING ROAD 1 JONATHAN NUTTING ROAD





GROTON 115

JONATHAN NUTTING ROAD RD



H
owever, it cannot be found in the on-line massgis address viewer at
http://massgis.maps.arcgis.com/home/webmap/viewer.html?useExisting=1&layers=a0049ad319674c439516b2df1173d8f5

W
hy do the two ways to view the same information differ?
Do we understand the address point data?
