ESRI has published a how-to guide on building web maps showing Sheriff Crime data with ArcGIS Online: read the post here
The reason this post hit me was not so much for the fact that it uses LA County data, which is great, or the fact that our Sheriff department shares this data (which is even better – kudos to Wendy Harn!!!) – but that it shows the value of making our data open, updated, and easy to find! This increases access to developers, who can make the data more visible to citizens, improving their understanding about what goes on around them, and potentially improving their lives.
What sparked this “epiphany” was this little banner on the top:
As of April 30th (8 days after the post):
- 52 people had shared this on Facebook (this goes into their timeline)
- 120 people had shared this on Twitter
- 200 people had shared this via Tumblr.
- 372 total shares.
Well – 372 folks doesn’t seem like much, until you realize that means that this has been shared with ALL of their friends and followers – so we may be talking about thousands of other people. Each one of them can backtrack to both the ESRI post, as well as the LA County GIS Data Portal. So they may end up using the instructions to create their own maps and applications, learning both about GIS, crime, and analysis, but maybe finding other data that they have interest in, and can work with.
Maybe one of them will build an application like crimemapping.com that does some neat analysis (supported by the Sheriff and other police departments), combined with other data that we have, to do some neat work.
A Map Of NFL Team Allegiance POPULAR SCIENCE – NEW TECHNOLOGY, SCIENCE NEWS, THE FUTURE NOW | JANUARY 30, 2013
“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.”
To get the word out even further about what we are doing in LA County in terms of geography, I am connecting the content that I publish on this site out to my Facebook account, and (more importantly) enabling visitors to “Like” various posts which will link us out to the Facebook community, connecting the information we publish to more people!
So – if you have a facebook account, you can like the content you find interesting!
I should have done this before our big outreach (GIS Day), which is tomorrow, but late is better than never!
So if you are in LA tomorrow, check out GIS Day: http://gis.lacounty.gov/gisday
There are a number of open source data visualization packages out there – R is one of them, and there are a LOT of very cool things that folks can do – take a look at this one:

You may recall seeing this great visualization from Facebook last week on the links between friends. Well the creator of that graphic has blogged about how he did it using R and some amazingly simple processing. R is one of those tools that isn’t used in our space enough (really, you use Excel for analysis?) and if this doesn’t open your eyes to its great potential, your priorities are in the wrong place.
