I just ran a backsearch using Twitter Search with a geo focus of a
circle of radius 210 km around the epicenter of the quake. This gets
the westernmost tip of Haiti, but includes some of the Dominican
Republic. Eventually I'll be coding the Streaming API version of this,
but there aren't enough geotagged tweets yet to make it worth doing.<br>
<br>
What did I get? 7500 tweets total - the earliest was from "Thu, 21 Jan
2010 20:46:12 +0000". I don't know if that's because Twitter wasn't
functional before that or for some other reason. Twitter Search
normally goes back at least a week, and it can go back longer. Of those
7500 tweets, only 93 were geotagged. I've left the data in JSON format,
UNIX line endings. I have a script that converts them to CSV, but it
needs to be enhanced to include the geotagging data when it exists. I'm
in no hurry to do that, since my understanding is that the various
projects are directly integrating Twitter data. The file is<br>
<br>
<a moz-do-not-send="true"
href="http://github.com/znmeb/Twitter-API-Perl-Utilities/blob/master/haiti_quake_backsearch_collected_data.json"
target="_blank">http://github.com/znmeb/Twitter-API-Perl-Utilities/blob/master/haiti_quake_backsearch_collected_data.json</a><br>
<br>
It's about 3.7 megabytes.<br>
<br>
I also got a list of tweet counts for all the users represented in the
search result. If a user is in this list, they either sent a geotagged
tweet from inside the search circle, or Twitter thinks their profile
location is inside the search circle. That file is<br>
<br>
<a moz-do-not-send="true"
href="http://github.com/znmeb/Twitter-API-Perl-Utilities/blob/master/haiti_quake_backsearch_tweet_counts.csv"
target="_blank">http://github.com/znmeb/Twitter-API-Perl-Utilities/blob/master/haiti_quake_backsearch_tweet_counts.csv</a><br>
<br>
There are 579 users in that list. That's not a horrendous number to
expect human curation on at this stage of the game, and if anyone so
desires, I can pull their profiles into a spreadsheet and even download
their most recent 3200 tweets. ;-)<br>
<br>
Please feel free to forward this to anyone you thing would be
interested. I'm going to see if anyone on the main "CrisisMappers"
mailing list has an interest.<br clear="all">
