LARIAC Training Dates

For LARIAC participants, Pictometry will be providing a number of training opportunities in the coming months.  Read the descriptions, and register if you are interested.

Map of London V2 rocket sites

Thanks to Warren Roberts for sharing:

Read the article – but what was interesting to me was this line:

We’ve mapped out some of the impact sites above, with more to follow when we can access further information. Make sure you zoom in and check satellite view. Commonly, an area hit by a V-2 is now covered with a car park or 1960s housing estate. These areas are usually devoid of mature trees, and still stand out over 60 years on.

Something that happend 70 years ago still reverberates in Land use planning today!

Longest Beaver Dam in the World

Longest beaver dam in the world

I saw this article the other day (World’s largest beaver dam explored by Rob Mark) where he trekked 9 days to get to this beaver dam (don’t ask me why).  What was interesting to me, though, was the fact that this dam is close to 30 years old, and was found on Google Earth.

Some other links in that application took me to a website where I learned more about this beaver dam than I ever thought I would.  However – what really was interesting to me is how detailed, and how historic, a lot of the map were.  There are maps from 50 years ago, 3D maps, elevation profile maps, geologic maps, LANDSAT maps – all to describe this one beaver dam.  If you love beavers, or if you love maps, while the article is VERY academic, you have to love the maps (and the beavers of course).

Rooftop Reflectance Map released by Berkeley Lab

LA-zoomPretty cool map released by the Berkeley Lab of rooftop reflectance.  I checked and they are using the Building Outlines that we released to the public, which is good to see.

Click here for the full press release

Two things I hope they do:

  1. Make the data available to the public for download, and/or
  2. Allow inclusion into other websites, like the County’s Solar Map

That would allow us to do some serious analysis.

LA County GIS Directives

LA County released a set of GIS Directives as authorized by the CIO and the Chief Exectuive Officer a years ago – I wanted to share.  There are three directives:

  1. Enterprise GIS Repository – which mandates that departments will publish authoritative data to a central repository for sharing, and further published to the GIS Data Portal if not confidential.
  2. Centralized Software Management – all ESRI GIS software will be acquired through a single maintenance contract with ESRI.
  3. Central GIS Infrastructure – all GIS applications (with some exceptions) will be hosted on a central GIS infrastructure.

LA County releases Preferred Technologies for GIS

This document lists the preferred Geographic Information Systems (GIS) technologies for the County of Los Angeles.  This document is designed to help GIS and IT personnel identify technologies during proposal and contract development, procurement, and acquisition of new systems to ensure that they are compatible with existing GIS systems within the County.  This document supports the Chief Information Office’s mission of reducing redundant development platforms and streamlining the development, storage, maintenance, and access to geographic data and GIS application development.

Click on this link to download the full document: CIO Preferred Technologies for Geographic Information Systems – September 2014

To see more of our framework documents, go to the documents page of the eGIS Steering Committee (click here to view).

At its heart is the following table which lists the various tiers of a GIS system, and our preferred technologies.  While the County does not enforce these technologies as standards, it is noted that GIS systems not using these technologies will receive increased scrutiny by the Chief Information Office and the Geographic Information Officer.

Time-lapse visualization of city annexations

Check out the time-lapse visualization of city annexations on the County’s GIS Viewer! Watch the growth of cities occur incrementally in LA County.

Expand Political Boundaries > Expand City and County Boundaries > “Turn on” the City Annexations layer and the time-aware slider will appear. All you have to do next is click on the play button on the left-hand side of the slider.


TimeLapse_GISViewer37 TimeLapse_GISViewer59 TimeLapse_GISViewer100

There is a 36 year time period when the City of Los Angeles and the next city, Pasadena, became annexed so nothing will occur – be patient until the slider reaches to a time extent of “~37 years, 2 months”.

If you zoom in, you will see the annexation years as labels:


Change the transparency on the ‘Political Boundaries’ layer group to view the underlying base map:

LA County mourns the loss of Peter Fonda-Bonardi

It was with great sadness that the GIS community learned of the passing of Peter Fonda-Bonardi on September 13th after a long illness.  For those of you who knew him, you know that we lost one of the leaders of GIS in Southern California, a man who contributed so much to all of us with his passion, expertise, dedication, and love of life.  His work has supported the Census, our address maintenance, redistricting, mapping, precincting, jury allocations, and too many other government efforts to mention.

Peter was a mentor to me when I first started with the County – sharing his advice, wisdom, experience, and work for the greater good – I have missed his energy these past few years, but a lot of what I have done and much of the strategy that I follow, from sharing to open data, are direct results of the way he showed me around his County.

There will be a memorial service for him on October 18 at 9 a.m. at The Church in Ocean Park, 235 Hill St., Santa Monica 90405.

After the service you are all invited for refreshments at the home of Mario and Sylvia Fonda-Bonardi at 2421 Second St., Santa Monica (2 blocks north of the Church).  If you have questions, call Mario at 310 699-0374.

eGIS Committee Agenda for Tuesday, September 16th

Please find the agenda for Tuesday’s eGIS commitee meeting attached (September 2014.eGIS meeting notice and Agenda)

We will be discussing:

  1. Updates on LARIAC and CAMS
  2. Information about the shared GIS folder, and the new demographic datasets that are available (Download the Demographic Data Brochure)
  3. An update from the GIS Day committee
  4. An update on the GIS positions reclassification

Doug Morales from DPH will also give a demonstration of the DPH GIS Viewer, which should be very informative as well.

See you there!
