Deploying a VGI application in one day Tom Brenneman

Agenda What is VGI Social media and geo-location Working with crowd sourced data Templates ArcGIS in the cloud

What is VGI? Volunteered Geographic Information - Capture content from the community Two aspects - Geographic and Map-based data collection - ArcGIS, Web Maps - Geo-location data collection via social networks - Twitter, Youtube, Flickr

How can VGI be used? Situational awareness Open government New Zealand Earthquakes Citizen Service Request

Twitter Micro-blogging, messaging and networking platform Post messages (status updates) Follow others Others can follow you Service for sharing information Anyone, Anything, Anywhere, Anytime, Any Device

Examples of status messages - “tweets” I noticed a brush fire off the 10FWY south of the 91FWY interchange. Anyone dispatched yet? #LAFires Traffic accident off of the 38FWY near Big Bear Lake. #SoCalTraffic Anyone know where there’s still parking available for the baseball game tonight? #OregonEvents Pseudo-geotweets

Anatomy of a tweet Downtown LA. Traffic accident on I10. Backed up for miles. Anyone know how the I60 is? #Traffic What’s happening? To whom? Geolocation?

GeoTagging Tweets Applications can append coordinates Users must geo-enable (opt-in) accounts string url = string status = “At the IGIC conference learning lots of cool things… #IGIC2011”; string request = string.Format("lat={0}&long={1}&status={2}", lat, lon, status); ‘ Geolocation enabled ‘ Geolocation not enabled Learn more about geotagging tweets

Twitter Service APIs 1. Search - ATOM or JSON 2. REST 3. Streaming Free, simple, access from many clients (HTTP) Authentication, rate limiting, whitelisting Use API to integrate tweet + location into GIS Learn more about the Twitter API

What other services can be used? Filckr - Can expose geotag - content tags Youtube - Map location - content tags Ushahidi - SMS, MMS, web form - Opensource - event specific Others?…

How to integrate with crowd sourced data? Client side - Web application queries geo-location content - Benefits - Easy / Fast to deploy - No data management Server side - Script integrate community content into GDB - Benefits - Can support many more clients - More options for filtering content - Violation of twitter terms of use

Quick start templates Template include everything you need to build a solution - Application, maps, sample data Social Media/VGI App – Version 2 - Geo-location data collection via social networks - Twitter, Youtube, Flickr, Ushahidi Citizen Service Request Template for ArcGIS 10 - Geographic and Map-based data collection - Community uses the map to add data

But how can I deploy this template in 1 day?

What is Amazon Web Services (AWS)? A Cloud Infrastructure - Data centers around the world Accessible via Web Services - EC2 (Elastic Cloud Computing) - Cloud Watch (Monitoring) - Cloud Front (Web Content Delivery) - Virtual Private Network (Secure networks) - Simple (S3) and Block (EBS) storage (Storage) - Following a ‘pay as you go’ business model We will sometimes refer to it as ‘the Amazon Cloud’

Advantages of running Simplified management Preconfigured machine images Monitoring, back-ups, scaling Real time access to massive amounts of Computing power Network bandwidth Storage No long term investments in infrastructure Elastic computing ArcGIS Server on Amazon EC2 Storage Computing Networks

Amazon Machine Images (AMIs) A virtual image that works in the Amazon Cloud A cookie-cutter approach for configuring servers OS + Software + Data ESRI provided AMIs: ArcGIS Server 10 AMI Enterprise Geodatabase AMI Windows bit ArcGIS Server GIS Services Microsoft SQL Server Express (ArcSDE enabled) ArcGIS Desktop 100Gb of storage (optional) Windows bit PostgreSQL (ArcSDE enabled) 100Gb of storage (optional)

How do I get the data out of the cloud? FTP / Copy pasteFTP / Copy paste Geodatabase replicationGeodatabase replication With on-premises existing infrastructureWith on-premises existing infrastructure Cloud to on-premiseCloud to on-premise On-premise to cloudOn-premise to cloud Two way synchronizationTwo way synchronization Cloud = inputCloud = input On-premise = QAOn-premise = QA Geodatabase replication Over http/s
