ESRI Tools & Resources for Haiti (& other) Response Efforts

Updated: Jan 21, 2010:

TwitterSearch Flex viewer Widget: http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGalleryDetails&scriptID=16782 
The idea for this widget came about at the Random Hacks of Kindness event in CA back in Nov 2009. The BarCamp discussions had a lot of talk about crowd-sourced information, especially Tweets. We weren’t able to complete the code for this widget at the event, but now it is ready for prime time (well, beta prime time). It is a multi-fuction widget in that you can search for Tweets within a draw radius area (like around the island of Haiti), and you can also filter your radius search results by up-to three keywords or hashtags. This widget also allows you to send Tweets, and even better – geo-locate those Tweets. So if you are Tweeting about something happening somewhere else, you can locate the Tweet in that area. Widget is also ready to go in the GEO Viewer. Thanks Andy!

Accessing OpenStreetMap data within ArcGIS to support the Haiti Earthquake Response: http://blogs.esri.com/Dev/blogs/publicsafety/archive/2010/01/20/Accessing-OpenStreetMap-data-within-ArcGIS-to-support-the-Haiti-Earthquake-Response.aspx 
This post on the ESRI Public Safety blog discusses how you can use OpenStreetMap data in ArcGIS Desktop. With all the work being done on updating these data post-earthquake, this is useful information.

Free Flex Sample viewer: http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGalleryDetails&scriptID=15905 
This sample viewer allows you to build a website without needing ArcGIS Server. It hits freely available ArcGIS Online data and allows for some viewer customization via configuration files, so no need to compile code. You can also deploy some of the free widgets available from the Resources pages. Some examples of widgets you may like to include are:
- Twitter Geospatial Search Widget (draw a radius on the map to retrieve geo-located Tweets within that area): http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGalleryDetails&scriptID=16448 
- Google Streetview Integrated with AGS Flex API (click on the map to grab Google Streetview at that location): http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGalleryDetails&scriptID=16070 

GeoEye Image Service published in the Amazon Cloud: http://events.arcgisonline.com/ArcGIS/rest/services/GeoEye_Haiti_Jan13/ImageServer 
More services: http://events.arcgisonline.com/ArcGIS/rest/services 
January 13 GeoEye imagery as an Image Service for REST, SOAP or WMS access

Tools available from ArcScripts for working with OpenStreetmap data: http://arcscripts.esri.com/scripts.asp?eLang=&eProd=&perPage=10&eQuery=openstreetmap 
Query on ArcScripts for OSM related entries.

Free tools and widgets available for your mapping websites:
- Flex:
- Silverlight:
- JavaScript:
- .NET:
- Java:
These are all part of the user communities for each product. ESRI supports and encourages the sharing of code through these community pages.

Geo Status Widget for Flex Viewer: http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGalleryDetails&scriptID=16686
This widget allows you to geo-locate a Tweet. So if you want to reference a Tweet to an event or location without being there, this is one way to do that via clicking on a map to select the location. This widget was developed onsite at the Random Hacks of Kindness event Nov 2009.

ArcGIS Online Haiti Earthquake: http://www.arcgisonline.com/home/group.html?owner=esri_event&title=Haiti%20Earthquake
