Twitter is a free social networking microblogging service that allows users to broadcast short posts called tweets. It’s used widely by individuals, as well as federal and local government agencies, organizations, and businesses. Tweets can include location (a user account … Continue reading
ArcGIS Online’s Make a Web Application gallery includes three templates that leverage the Twitter API to add geolocated tweets to your maps. Twitter recently announced updates to their API, and now requires authentication on all Twitter endpoints. For more information … Continue reading
Want to know what’s going on with Hurricane Irene and see for yourself what folks on the ground are saying? Here’s how you can quickly make your own ArcGIS Online Hurricane Irene map, add geo-located tweets, and share your map with others in three quick and easy steps.
Step 1: Get your map
You can start off with a new map and hunt for services to add, but there’s no reason to do that when there are a number of hurricane maps already available that have been publicly shared. So we’ll start by going to ArcGIS.com and search for the keyword “Irene:”
This year the focus of the GeoWeb conference was on “Going Real Time”.
In our presentation, we discussed how to build client and server GIS applications that consume real time Twitter data. We covered a number of real world scenarios that this could be applied to such as disaster management, emergency scenarios and so on. We also covered some of the challenges we face when building systems like this.
GeoWeb 2010 Real-time ArcGIS Twitter Map
In the spirit of supporting the “real time” theme of the conference, we also demonstrated how to use the ArcGIS platform to build a real time mapping system to track conversations on Twitter. The system (code named “TweetBase”) had the capabilities of capturing all of the ”GeoWeb” conversations that took place during the conference, geolocate them, and publish them on a web map on ArcGIS.com.
Here is an example of the map in a browser and mobile client.
2009 was the first DevSummit where people really used Twitter
to talk about the event. I followed the tweets from here in New York and it gave me enough insight into the event to whet my
appetite to attend this year.
With the incredible growth of Twitter since then, we all
stepped it up a notch for the 2010 DevSummit. The official @ESRIDevSummit
account kept people up-to-date on announcements while a number of us, ESRI
staff and the developer community alike, broadcast their thoughts and photos of
The inevitable backchannel
All this tweeting provided real value to those of us who
couldn’t make it in person, and many people thanked us for providing so many
updates. I felt the tweets communicated not only the content of the DevSummit,
but also that it was fun, that people were busy and enjoying themselves.
With thousands of tweets
in total the sheer size of the backchannel was fantastic (there was even a day-by-day favourite tweets series). In fact, some people were able to write summaries of
the plenary and other sessions based off it. I checked out some of those posts
as they were published and they were pretty spot on.
To Tweet or not to Tweet?
Many people still question me on the value of Twitter
(because I’m a geek and have a twitter account, not because I claim to have an
opinion), and I don’t blame them. It’s not right for everything. But the DevSummit is a great example of just how Twitter can work really
well: People were tweeting announcements, commentary, opinion, conversation,
troubleshooting, and behind-the-scenes, all of which made for great reading. But twitter also often provided practical benefit. A big part of the DevSummit is about being in the same room as ESRI staff – the whole “grab a red badge” thing. With twitter, people were able to do that without getting out of their seats: we got projectors corrected, firewalls adjusted (or else we explained why they couldn’t be), features confirmed, and so forth.
It was a tremendous event, and even with the videos being made
available online and the informative backchannel over Twitter, I wouldn’t miss it. Getting together with your colleagues and our teams in a dedicated environment where
everyone’s mind is on software is such a rich experience. Nothing gets close to replacing that, but Twitter makes up for some of not being able to make it.
The DevSummit organisers and the EDN team in particular would like to thank all the geo-tweeters for doing such a great job. It was a pleasure meeting some of you in person at last. And here are some tweets of gratitude from people who couldn’t make it:
- @ikendoh: Thanks to all at #devsummit for interesting tweets. Couldn’t make it there myself but still learning from you all.
- @amandahstaub: Huge thank you 4 their coverage of #devsummit: @sathyaprasad @geeknixta @Taliesn @JimBarry @Kirrilian @davescheirer @dbouwman @cageyjames
- @storm72: Thanks to all who tweeted #devsummit. It’s very much appreciated out here in the #geohinterlands.
- @mattpriour: Just closed the #devsummit pane in Seesmic. Sad not be there so thankful for all the tweets. Excited about ArcGIS X !
With that, I give you a top-20ish list of DevSummit
