00:01I wanted to start off by giving you a little bit of background to this.

00:03On the 4th of September, 2010, around 4:30 a.m., Christchurch awoke to a 7.1 magnitude earthquake.

00:12A couple hours later, we were on the phone to our users down there offering as much assistance as we can.

00:18This wasn’t about business, but it was about survival and about doing the right thing for our users.

00:24A couple hours later, we worked with our users to get them on board with a number of things.

00:33And then two weeks ago, unfortunately, like John mentioned, a 6.3 magnitude aftershock rocked Christchurch.

00:41And this has caused massive damage through most of the region.

00:47Due to this, a national state of emergency’s been declared in the country.

00:52Unfortunately, unlike the previous earthquake, this has caused a number of fatalities as well.

00:56But it’s great to know that there is a number of international search and rescue teams...

01:00...working on the ground in Christchurch to help in the rescue and recovery effort.

01:05As you can see from some of the facts on the screen, it is going to be a little while before New Zealand is back...

01:10...or at least Christchurch is back up to it’s normal state.

01:14So I was wanting to share with you some of the ideas in the areas that we’ve been working in.

01:19I wanted to start off with data.

01:21I emphasize this quite heavily because it was one of the most important parts...

01:25...and also the hardest parts for us, working through this earthquake response.

01:30We were dealing with around 10 different agencies, four different GIS systems...

01:34...and formats of PDFs, CSVs, Excel documents, all coming in.

01:39In the initial earthquake, ArcGIS 10, plus the Data Interoperability extension, allowed us to work with this data.

01:45But it was more than this. It was about being smart and using the tools in a way that we can automate certain things.

01:52ModelBuilder helped us through this process.

01:55But we’ve taken it a step further now. We’re now using Python scripting to automate it totally.

02:00Data’s being fed into landing folders...

02:02...and Python scripts are being automatically run to update data that go up into the public viewers.

02:08ArcGIS 10, plus a templated structure, has allowed us to enable editing.

02:13We really wanted to do this in the initial earthquake, but we weren’t able to.

02:17Right now, we have securely enabled editing environments...

02:21...where a number of the agencies are feeding information and updating statuses of roads...

02:26...and other sort of structural incidents, et cetera, all through...live to the public.

02:30This has allowed us to focus more on the sites, rather than worry about the data.

02:36Talking a little bit about infrastructure.

02:38We’ve been doing a lot of work in cloud computing in New Zealand in the last six months...

02:42...and it’s been a really interesting area as cloud computing grows.

02:46But one of the things we found is that we haven’t done enough to be prepared for something like this.

02:52It’s not just about being able to throw up an ArcGIS Server in the cloud and saying, we know, We’ve got it running.

02:57It’s about having a system in place, having your network in the cloud, having databases in the cloud...

03:02...authentication servers ready to go, when something like this strikes.

03:07And we’re getting there. We’re working on that.

03:09We know it’s a mistake and we’re working on it to make that possible.

03:15I wanted to touch a little bit on the viewers that we had.

03:17In the initial earthquake, we launched a Flex-based viewer, which was used as sort of a incident viewer.

03:23In the current earthquake response, we’ve changed this to a JavaScript-style viewer.

03:28This viewer is being used to showcase a lot of the operational-based information...

03:32...whether that be where the location of water tankers are, portaloos, et cetera.

03:39We’ve also been able to bring in social media, and I’ll talk about that in a second...

03:42...and rope in a lot of those feeds from a number of sources, as well as open this up to a number of secure sites.

03:50The bus routing system in Christchurch has just got off the ground and is now live...

03:54...showing the public how to find bus route information.

03:57And as I mentioned, secure access for agencies to view postearthquake imagery...

04:02...and other high-resolution images as they come out of the ground.

04:08Mobile and the lack of it. And I mention this because we didn’t do enough in this area.

04:13In the first earthquake, it was too late by the time we actually got mobile up and running.

04:21In the current earthquake, it’s now been about two weeks, and as far as I’m aware, they’re still not using mobile in the field.

04:27And for us, it’s about educating our users and getting them better prepared...

04:31...to utilize mobile technology when an event like this strikes.

04:35We’re working with them to try and make this possible right now.

04:39From a social media perspective, I want to emphasize the fact on how much social media has played in this Christchurch earthquake.

04:46For the first three days at least, a lot of the information coming from the ground was actually being fed through social media channels.

04:52You saw on that screen shot, we were able to bring a lot of those together...

04:55...a lot of the Ushahidi feeds from the crowdsourcing perspective, Facebook, Twitter, YouTube...

05:01...bring it all into one view where the public can actually see information straightaway.

05:06It’s been a great working relation...we formed a great working relationship with many of our users on the ground.

05:11They’ve been our contacts there and we’ve been their contacts with technology.

05:15But in all of this, there’s a new definition to the term “preparedness.”

05:20For me, it’s about understanding...understanding technology ahead of time is key.

05:24Having the tools and the skills in place and having the people to support a disaster like this is vital.

05:31It’s been a touching experience, not being on the ground in Christchurch was, and still is, quite a hard, is quite hard...

05:38...but there’s been a great desire to help from the GIS community.

05:42I’m sad to have left New Zealand to be here attending the conference...

05:46...but what we have put in place right now with some of the automated ways of working is great...

05:50...and it is working and that’s the great thing to know.

05:54Charting a course together over the last six months, we have learned a lot...

05:58...and much of which is being used on the ground right now in Christchurch.
