LA County Publishes its GIS Data Catalog

In order to make our data easier to find, sometimes a nice table or spreadsheet is what you want.  LA County has created a new page which lists all of the GIS Data Los Angeles County has identified in its systems, compiled and organized, with active links on this site to where the data can be downloaded.  This should make it easier to find and access its data, and avoid some of the potential hassles of searching for data one by one.

The data catalog is located here:

As well – if you have any feedback, don’t hesitate to provide that to them here:

LA Lakers Star Kobe Bryant’s Last Shot (in GIS)

If you are both a basketball and GIS fanatic, be sure to check this out.

The LA Times has a leaflet map viewer showing every shot Kobe Bryant ever took – all 30,699 of them. You can explore makes and misses over his career, view buzzer beater locations, as well as shots taken during his final game with the LA Lakers on April 13th.

With this type of tracking data available – spatial analysis could be used for coaching decisions and other impressive visualizations!

Humanitarian OpenStreetMap Team (HOT)

The Humanitarian OpenStreetMap Team (HOT)’s stated mission “applies the principles of open source and open data sharing to humanitarian response and economic development”. In a nutshell, HOT coordinates the work of OpenStreetMap volunteers and aerial mapping vendors, etc. in response to disasters in various parts of the world.

Volunteers often work from the comfort of their own homes, creating data used by first time responders and for helping with disaster recovery efforts. The HOT Tasking Manager shows their responses to the recent earthquake in Ecuador. To learn more about HOT, please visit their wiki.

US Supreme Court was required to settle GIS boundaries

boundaryI recently became aware of a valuable data resource (the Bureau of Ocean Energy Management GIS data download page) – and in poking around one of the more valuable layers for the County  (the 3 Mile boundary which is actually the County Boundary) I found out about a lawsuit that had been going on for over 100 years to determine who owns the rights to minerals offshore the State of California.

In 2014, it finally took the Supreme Court to determine the jurisdictional boundaries between the State of California and the federal government in the Pacific Ocean (the Submerged Lands Act).

Upcoming Mapathon – importing LA County buildings into Open Street Map

Passing this along:

We’re reaching out to you and the County GIS department about an upcoming mapathon Saturday April 2nd at the LA Times in downtown LA  to get people together to edit OpenStreetMap and import all the buildings in the City of Los Angeles!

This is part of a larger effort to import all 3 million buildings in Los Angeles County using open data from the LARIAC (Los Angeles Region Imagery Acquisition Consortium) Program and the L.A. County Assessor. The import will improve Southern California’s maps by adding building shapes and data on heights, elevation, general use, year built, and the number of residential units.

As we finalize the process to allow mappers to add this data to OSM, we need your help in spreading the word to anyone interested in learning and contributing to this platform built by a community of mappers.

In the run-up to our first mapathon being held Saturday April 2nd, a tutorial session will be held to teach OSM basics as well as JOSM, the editing tool used during the mapathon. The session will be led by the Los Angeles Chapter of Maptime on March 31st 6:30PM, a group whose mission is to open the doors of cartographic possibility to anyone interested by creating a time and space for collaborative learning, exploration, and map creation using mapping tools and technologies.

Our efforts are documented on github and the OSM wiki page, where you can follow and contribute your knowledge as we work towards completing this project.

Looking forward to hear from you!
