LA County (RRCC) Looking for Help Locating Vote Centers

This came through Nextdoor – from the LA County RRCC (related to Vote Centers).

In 2020, we’re stepping away from polling places and moving to Vote Centers – providing voters with greater convenience, accessibility and time to vote. We want YOUR help in choosing the locations of these Vote Centers.

The key part for the GIS community – Suggest a location for a Vote Center: (go to ‘Suggest a Vote Center’ under Community Engagement).

Modernizing the voting experience is stemmed directly from the California Voter’s Choice Act, which some Counties in CA are already implementing.  View our CA Voter’s Choice Act factsheet for more info:

Take a look at what the future Vote Center model looks like: If you have any questions go to our Contact Us page:   Thank you.

Welcome Steve Steinberg! New LA County GIO!

Re-posting – because it’s important (thanks Michael Carson).

Congratulations to Steve Steinberg on becoming the new Geographic Information Officer (GIO) for the County of Los Angeles. He will be working from the Internal Services Department (ISD); for those of you that want to know.

Before joining the County, Steve was the Principal Scientist and Department Head for Information Management and Analysis at Southern California Coastal Water Research Project (SCCWRP), a public agency for environmental research located in Costa Mesa.

Steve has extensive experience with geospatial analysis technologies including GIS, remote sensing, and image analysis in interdisciplinary applications.  He has a B.S. in Natural Resources, a M.S. in Natural Resources Policy and Management, and a Ph.D. in Forestry (Geospatial Sciences).  He also has co-authored books, such as GIS Research Methods: Incorporating Spatial Perspectives (2015) and GIS for the Social Sciences: Investigating Space and Place (2006).

Oblique satellite imagery from PlanetLabs

Wanted to pass this along:

These are oblique imagery from the satellites from Planet Labs.

There are some potential applications, too, beyond the “wow” factor of the images. Taking stereo images of an object from different angles will allow for the derivation of height. And taking images from many different angles will allow for the construction of a 3D model of a mountain or be used to track urban growth in cities.

There is even enough resolution in the SkySat images for commodity traders to track the volumes of coal at a site, the depth of mines, or even to determine the height of shipping containers to measure the outflow of goods from a port.

A bit creepy, but GIS nonetheless.

Big Data Day LA 2018

This post has been updated. The original, August 18 date has been moved to Saturday, August 11. Per Subash, valid tickets issued with the previous tentative date will still be honored.

Registration for Big Data Day LA is now open.

There has been a rise in the field of Data Science and a host of technologies that surround this field. With over a dozen different knowledge tracks, this event covers a wide range of subjects ranging from material that will challenge hard core data scientists down to introductory material for newbies in this field.

These presentations explain technologies like the IoT, Hadoop, Spark, Redis, Artificial Intelligence/Machine Learning, Predictive Analytics, etc. Examples of the use of these emerging technologies in GIS can be found in the FOSS4G 2017 presentations or this short video from Planet (formerly Planet Labs).

When explaining Big Data, I like to use this example. Once upon a time, TV ratings were computed from a handful of Nielsen boxes placed in a given city. Today, every second watched by every PC, phone, or tablet on Netflix is tracked, and new content is created based on predictive analytics.

Date: Saturday, August 11, 2018
Times: 8:00 AM to 7:00 PM
Where: USC Marshall School of Business, Los Angeles
Cost: Free if you register before April 30; $40 if you register in May and June

Notes: This event usually fills very, very fast.
