Parcel Viewer Superceded by GIS Viewer

County staff and LAR-IAC participants have had access to comprehensive property information through the Parcel Viewer. This is an important message for those staff that use the Parcel Viewer.

Parcel ownership data has been moved from the Parcel Viewer to reside in the GIS Viewer. This eliminates the need to access two separate applications. Once you have launched the GIS Viewer and you wish to access parcel ownership data, click on the “Sign-In” link located at the top right corner of the interface.


Access to parcel ownership dataset is restricted to eGIS department members and current LAR-IAC members. Training is available on Feb 8th, 10th, and 17th. To sign up, go to https://www.wejoinin.com/sheets/mpylb.

GIS Viewer launch link: http://gis.lacounty.gov/gisviewer

Microsoft Silverlight needs to be installed on your computer. The HTML5 version (for mobile and tablet) will be coming in the next few months.

If you have any questions, please contact Christine Lam (CLam2@isd.lacounty.gov) or Mark Greninger (MGreninger@cio.lacounty.gov).

GIS courses at Rio Hondo College

Passing along from Warren Roberts:

Spring semester starts first week in February at Rio Hondo College.  Course offerings can be located by clicking on this link.

Given a majority of our students are working, our courses conveniently scheduled in late afternoon & evenings.  We work closely with our civil and engineering course schedule (CAD required component of the GIS Certificate).

We have the step by step process from applying for admission to registering for class.  New students can be perform the steps entirely online.  Most classes are 4 units and last check @46/unit.

Block Boundary Suggestion Project – Meeting February 18

Hello everyone – Census 2020 geographic activities are starting – the meeting below is the first of these, and will focus on creating/updating Census Blocks, which is the smallest geographic unit of the Census.  There are 8 meetings across the state, but the meeting in LA County will be on Febuary 18th.

Thursday, February 18
Southern California Association of Governments
1pm to 3pm (SCAG)
SCAG Policy Committee Room B
818 West 7th Street, 12th Floor
Los Angeles, CA 90017

Full BBSP Invitation

Geography files, etc: http://www.census.gov/rdo/program_phases/2020_census_redistricting_data_program.html


Phase 1 of the 2020 Redistricting Data Program is the Block Boundary Suggestion Project (BBSP) being conducted in the first half of 2016. This program is your only chance to weigh in on the smallest Census geography that underpins all other Census geographies – the Census block. Are your block boundaries correct? Are they where you need them to be? Have a say in which boundaries are important to you and your jurisdiction(s) and which are not. California must streamline its blocks as the geography exploded between the 2000 and 2010 Census’ from 533,000 to 710,000 – more than a 33% increase. While this project is of high importance for Redistricting and electoral district purposes, don’t forget the substantial uses of small area data for other data tabulation needs such as for grant writing, neighborhood profiles, etc.

The BBSP is an important part of the geographic preparations for the 2020 Census. California has designed the BBSP to allow its counties the opportunity to provide input about the features that will be designated as boundaries for census tabulation blocks in the 2020 Census. The BBSP also allows counties to submit suggested block boundary changes that may be of use in the post-2020 Census redistricting process or for other data tabulation purposes. The Statewide Database at UC Berkeley is coordinating this program and will host 8 workshops throughout the state.

Videos of GIS Day 2015 presentations

If you missed our opening speakers, we had a video crew on hand to film the presentations from Bernie Szukalski, Ted Ross, and Lilian Coral.  They did a great job of kicking off GIS Day, and I wanted to thank Andres Trinidad and the DHS film crew for capturing these great moments.

Our presentation schedule and those presentations for which we received slides can be found at this link.

Changes to Canvas Basemap

For those folks who use our online mapping systems, and for those partners who directly leverage our map services, we are rolling out a number of small changes to our cartography in order to make our maps more accurate and useful, as well as more suited to mobile devices.

This post covers changes to our LA County Canvas cache.  This is the final set of changes to our maps – but if you have comments please let us know!

Based upon feedback, we have made a number of changes:

  1. Created new labelling and street symbology sizes for levels 19 and 20 – labels especially are larger and bold
  2. Increased the frequency of labelling when zoomed in.

Take a look at the changes below.  We hope that you like them.

LA County Image Change App

Explore changes over time in LA County using our high resolution LAR-IAC imagery.  Click and drag the time slider bar to see the changes between 2014 and 2011 imagery. Several bookmarks have been created for you to quickly see some cool examples of development and the effects of drought on the landscape (e.g. LAX, Santa Clarita, San Gabriel Reservoir).
