California’s Lone Gray Wolf moves around a lot!

Hopefully it finds what it is looking for!

Pictometry ArcMap Extension for 10.1

For LAR-IAC members, Pictomery has released its ArcMap extensions that will enable you to access the oblique imagery using ArcMap.  With the County moving away from locally hosted data (Network Image Warehouse – NIW) toward Pictometry Online, this is a critical enhancement to the suite of tools used to access oblique imagery.

Note – you will need your LAR-IAC organization or sub-organization username and login to access POL.

Installation files (with setup instructions): ArcMAP 10.1 – (4 Mb)

New Link in Z-NET Public

Z-NET Public ( has just been upgraded to give the public more parcel information. Now, instead of going directly to the Assessor’s Map Book Page (AMBP) when the APN link is clicked, the link now opens the Assessor’s Detailed Property Information Sheet for the selected parcel.
