A map of LA’s urban core?

LA's Core

LA’s Core

Mike Jenkins passed this interesting article about LA’s urban core along Wilshire and Santa Monica.  It’s an interesting hypothesis, and is similar to the “Walk Score” concept of mapping amenities near each other.  I think there are some issues (as are mentioned in the article) about it missing other cores such as Pasadena, etc – what do you think?

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.

New Link in Z-NET Public

Z-NET Public (http://planning.lacounty.gov/znet) 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. Not only does this page display a selection of parcel data but it contains links to other pages, including the AMBP and Parcel Change Activity, as well.

Please click on the image below to see the new APN pop-up.

I’ve been holding off upgrading to the newest version of iOS so that I wouldn’t get stuck with the Apple maps.  Now I can move forward!



City Boundary Updates

The LA County GIS program has completed the implementation of two October 2012 annexations (City of Santa Clarita and City of Palmdale) as well as some cartographic updates to the Port of Los Angeles (removing the city boundary checked linework from internal port/water boundaries).

This has been updated in all three map services (Street, Canvas, and Base) that reference the city boundary data.

The changes are seamless – samples are below
