I think this is indicative of where we are going as data providers – not just providing downloads (like our GIS Data Portal) but providing data as a service so developers don’t need to build the platforms to access the data in applications. ESRI is doing this with their ArcGIS Online, but we’ll see how well that works.

See the quote from the article below.
In the long run, Buckner said, he wants the bureau to be a source for mobile data, not an app builder.
“We can’t be in the business of developing mobile apps forever,” he said. “That’s not in the government’s interest. The creativity about the way people want to use our data is outside government, not inside. So we want to expose core things that show the range of things you can do with our data.”
By markgreninger, on January 9th, 2012 Thanks Junior for passing along – I think you’ll find it interesting.
| Remember about a year ago you filled out a census form? Well, here are the result of this process. What you will see is a Map of the US – not just the 48 states but all of the 50 states. Territories are not in the census – but they did provide information during this process.
So let us say you are in Virginia , you can go by county and as you zoom in by city to see the increase or decrease and then you can see the changes of the various races within these cities. Case in point Crystal City, VA raised up 74,2% overall from 2000… while all around Kansas City , KS has lost at least 15% around the city.
Look at places you know and also look at the map at thedarker brown location.You can zoom in and out to get the information on the places you know.
Use your cursor can move map around and you can zoom in on specific counties to get current stats. It is very interesting!
Fascinating!
Just glide your cursor over the map and it displays every county.
Can’t imagine how long it took to create this map!!

By markgreninger, on July 8th, 2011 I wanted to pass along to folks that the Census Bureau has agreed to fix at least one error that we have identified in the 2010 Census Tract Boundary file – specifically the accidental merging of 2 tract from the 2000 TIGER file (tracts 1370.00 & 8002.01) into a single tract (8002.04) in 2010. This meant the tract boundary didn’t follow the boundary of LA City, which would create problems for historic comparison, as well as jurisdictional reporting.
If you are using the Census Data, please be ready to download the data when it becomes available.
From Tim McMonagle
‘Geography Division and all the other divisions involved have agreed that this situation warrants correcting. I have restored Census Tract 137000. This tract was unchanged in your PSAP submission. CT 800204 no longer extends north of Hwy 101 and the boundary follows the city boundary. Keep in mind this change will not show up in the next release of the next public TIGER/Line files.’
Click here to see a pdf document showing the error. On the map – follow the blue lines (2010 boundaries) – you will see the “isthmus” that connects the northern portion of the white area (LA City) with the southern green portion (Calabasas).
By markgreninger, on May 2nd, 2011 LA County releases online redistricting tools for public involvement in the redistricting process.
If you would like to try your hand at drawing the County’s supervisorial districts, try the County’s online redistricting tools: http://redistricting.lacounty.gov/index.php/create-plan-using-county-software/
You’ll need to register before you can begin updating the districts. I would definitely recommend taking a look at the principles, since it is a complex process: http://redistricting.lacounty.gov/index.php/laws-and-principles/

By markgreninger, on March 9th, 2011 So – the number is in, and the questions (I’m sure) are on their way. The Census released population figures from the 2010 Census yesterday as part of the redistricting process yesterday!
LA County’s population increased by only 299,267 people between 2000 and 2010, from 9,519,338 to 9,818,605. Still a lot of people!
Here are a couple of initial files that were sent to me:
To get the data yourself – here is the link to the Census website: http://www.census.gov/rdo/data/2010_census_redistricting_data_pl_94-171_summary_files.html
Personally, I’ve been quoting a figure above 10 million for a while now. My assumption is that we had a bell curve – that we gained many more people until the recession, where we lost population. Anecdotally, I believe that the northern part of our County (Palmdale, Lancaster, etc) was the center of growth for a while – this is perhaps where we lost of lot of people too.
My thoughts initially are to do both a spatial and a temporal analysis – showing changes in time and space. What is the best way to do this? What would you look at?
Have fun – lots more data to come!

By markgreninger, on December 16th, 2010 Thanks Hwa Saup for passing along.
Take a look at this app – the data volume it is outputting is impressive! You can move to LA with an address.
Old cartographic method in a new way. Very interesting map from NY Times.
