By Nick Franchino, on March 11th, 2013 This is a good article from Earth Imaging Journal Magazine regarding some things to think about when shopping for a wide-format printer.

By Christine Lam, on February 27th, 2013 The LA County GIS Viewer is fully running. The objective of the GIS Viewer is to publicize the County’s GIS authoritative data holdings and enable wide access to them through a powerful set of web-based GIS tools. Click on the image below to launch the viewer or go to http://gis.lacounty.gov/gisviewer. You will need to install Microsoft’s Silverlight tool in order to utilize the viewer.

For further information or to download the training manual and see training videos, go to the “GIS Applications” menu and then click on “LA County GIS Viewer”.
Have Fun!
By markgreninger, on February 12th, 2013 This could be of great interest to educational institutions out there:
“The US Geological Survey Pacific Region would like to find a new home for a complete collection of USGS 7.5-minute topographic maps of California. The map collection was compiled by the (formerly named) CA Department of Fish and Game Biogeographic Data Branch and represents one of a rare handful of complete collections for the state. The collection is contained in 6-7 steel cabinets that allow maps to hang vertically and be easily removed for inspection, use, and reproduction. Ideally, the collection should be housed in a publically accessible place so that agency representatives, land mangers and stewards, earth scientists, students, geographers, geocachers, and interested public can readily utilize, such as a university library or publically accessible government office. Required square footage would be a good-sized room (12′ x 12′) or wide hallway, as each cabinet has a footprint of about 4′ x 4′ (to allow for drawer opening). The maps contained in the collection are also available digitally, through the USGS store (store.usgs.gov) map locater.”
I will consider assisting to pay for moving charges if a good home can be found.
For more information email Carol Ostergren of the USGS.

“We’ve posted visualizations from Facebook’s Data Science Team before, but I think it’s safe to say that their newest effort–a county-level map of NFL fandom across the U.S.–is their most admirable yet. Based on the team page Likes and locations of over 35 million account holders, it’s probably the most accurate, precise geography of sports fandom ever.”

Mike Jenkins passed this interesting article about LA’s urban core along Wilshire and Santa Monica. It’s an interesting hypothesis, and is similar to the “Walk Score” concept of mapping amenities near each other. I think there are some issues (as are mentioned in the article) about it missing other cores such as Pasadena, etc – what do you think?

By markgreninger, on December 6th, 2012 The LA County GIS program has completed the implementation of two October 2012 annexations (City of Santa Clarita and City of Palmdale) as well as some cartographic updates to the Port of Los Angeles (removing the city boundary checked linework from internal port/water boundaries).
This has been updated in all three map services (Street, Canvas, and Base) that reference the city boundary data.
The changes are seamless – samples are below
By markgreninger, on November 1st, 2012 Election results can be difficult to understand – props to my alma mater Spatial Sciences Institute - for providing a good visualization of the fact that red/blue isn’t the only way to show voting patterns.
Here are the details: https://sites.stanford.edu/sssl/2008-obamamccain-vote-precinct - the map is below.
