EGIS Committee meeting for October


I will send out a more detailed agenda tomorrow but I wanted to remind folks of our meeting tomorrow. I look forward to a presentation from DPSS on their boundary redistricting project and we will discuss the classification exams and share notes.

See you tomorrow.

Maps of water use by water agency

per_capita_water_useWanted to share a pair of maps that someone made based upon the Water Purveyor Service Areas dataset available from the LA County GIS Data Portal.

This is the power of sharing – it comes back in interesting ways.

The Trouble with the Purple Election Map

Mike Henderson from LAFCO found this article – I think it is a great twist on one of the great mapping questions of our time – Red vs. Blue vs. Purple (and now Grey) chloropleth maps of elections.

FOSS4G 2014 Videos Available

If anyone missed the FOSS4G 2014 international conference in Portland, we can thank the presenters and event organizers for their generosity. This year’s 187 General Sessions were recorded and are available online for all of us.

The videos cover a wide range of subjects, including 3D printing, GDAL scripting, web development, and integrating open source tools into traditional GIS shops, to name a few. If watching these videos whets your appetite for more open source GIS, mark your calendars for FOSS4G North America on March 9-12, 2015 in San Francisco.

URISA Certified Workshops – to be Presented Virtually!

Passing this along from URISA.

URISA is pleased to announce the presentation of two of its most popular Certified Workshops via instructor-led web-based training.  Normally full-day classroom sessions, each workshop has been re-packaged into three sections for presentation virtually without the travel expense and time away from work. The workshop content is thoroughly peer-reviewed and updated each year and is eligible for GISP Education credit (8 hours of EDU-2). The cost to attend each virtual workshop is $195 for URISA members and $245 for non-members.

URISA’s virtual classrooms are limited according to the number of participants in order to facilitate online discussions and Q&A with the presenters. Individuals are encouraged to register early to reserve a spot. (Note that the workshops are recorded, so if for some reason you cannot attend all three sections of a workshop, you will have complete access to the recorded archive.) A registration form and FULL details are available online.


Introduction to Open Source GIS Software

This 8-hour workshop will be presented virtually over three days:

Tuesday, October 21, 2014 – 1:00– 4:00 pm EDT

Wednesday, October 22, 2014 – 1:00– 4:00 pm EDT

Thursday, October 23, 2014 – 1:00– 3:00 pm EDT

Course Description: Free and open source software (FOSS) has been offering choices to computer users for a number of years. Over the past few years the open source choices in GIS have been broader and more capable than ever before. This workshop will focus on GIS open source software. It will give an overview of current developments from technical and management perspectives. Selected packages and their applications in various projects will be demonstrated and discussed.


Asset Management: Planning, Strategy, and Implementation

This 8-hour workshop will be presented over three days:

Tuesday, November 18, 2014 – 1:00– 4:00 pm EDT

Wednesday, November 19, 2014 – 1:00– 4:00 pm EDT

Thursday, November 20, 2014 – 1:00– 3:00 pm EDT

Course Description: Public and private agencies face continuous challenges to accomplish more with less as increases in demand, regulatory requirements, infrastructure deterioration, and political and economic forces have significantly outpaced increases in capital and operating budgets. Many of these agencies are turning to Asset Management to cope with these challenges and improve business performance and effectiveness. This workshop will focus on several aspects of developing an asset management system that could help improve performance, reduce long-term costs, and maximize return on investment in infrastructure assets.

Map of London V2 rocket sites

Thanks to Warren Roberts for sharing: http://londonist.com/2009/01/london_v2_rocket_sitesmapped.php#_login

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.
