Congratulations to Scott Gregory (GIO of California) and his team – it’s a great start!

 

My quick takes:

  1. The sound clips talk a lot about mobile apps – looking forward to what that means
  2. I really like the application carousel –  it’s a pretty cool interface – but it doesn’t work in Google Chrome.
  3. My favorite map could be the Parcel Viewer – but it isn’t working – not good.
  4. The Viewer leaves a lot to be desired – throwing data on a map without any tools that provide context doesn’t help too much.  I think that Philadelphia’s map viewer is a bit closer to what we need – where you can switch between maps.  But on that map, too there aren’t tools that let you interact with the information in a way that is specific to each map.
  5. If this portal is for California, why is there Oregon data there?
  6. Under the gallery, the organization by theme is really cool,  but some of the links are just PDFs – don’t know if that is really what we need.  BUT as this part fills out I look forward to it – I just hope that the search capabilities are robust enough to clear out clutter.
  7. I am having some issues searching.

 

 

 Here’s a Video showing how to use it:

Congressional (2011)

2011 United States Congressional Districts clipped to the LA County Boundary.

This data was created by the California Citizen’s Redistricting Commission, and downloaded from their website.  Click here to go to the site.

This data is based upon the US Census Bureau’s TIGER basemap, and are not the final version for the County.  The TIGER file, while it represents physical features in the County accurately, does not have the same spatial accuracy as the County’s mapping layers.  The Registrar/Recorder County Clerk is currently updating their precincts to include these new districts, and with the same precision as the County base.

However, the County has tested and found the Census Bureau’s data to substantially accurate for even large-scale mapping, so future changes will not dramatically impact mapping, but I do recommend coming back to this page to check for updates.
