Earthquake Real-Time Data

As many know already, there was a Magnitude 6.1 earthquake in Haiti early this morning. The ESRI GEOSS/GEO Viever and perhaps others can help you visualize this. For those who might want to learn more about this earthquake and quakes in general, the USGS Earthquake Hazards programme provides lots of current information and of interest to GIS-ers, the data are also available for download or via webfeeds.

Haiti GIS Viewer

With the dire situation in Haiti there's a lot of spatial data including hi-resolution satellite imagery and from-the-ground vector data being generated to support the emergency humanitarian effort. The ESRI GEOSS/ GEO Viewer mentioned in the previous post is doing a great job of updating what it offers and providing an integrated view from the flood of data. It's a little slow, but I understand that it's had to make the leap from demonstration prototype to operational resource in a hurry; so full credit to the people behind it for doing so.

Earthquake in Haiti via GeoRSS feed

The scale of the humanitarian crisis caused by the earthquake in Haiti is now beginning to be understood. One source of information is the new GEOSS Viewer. Its use of up-to-date data, via RSS feeds, and its smooth interface makes it an excellent visualisation tool for both GIS Specialists and wider users such as the news media. It is a website that allows for the search of data across multiple data portals and has analytical capabilities, such as population estimations. It is currently focused on the disaster area of Haiti. There is a GeoRSS feed that will show the locations of the earthquakes there – from the USGS Earthquake data. The site is being enhanced with additional data and imagery to support humanitarian response operations.

The site is built using the ArcGIS Server API for Flex Sample Viewer, which is a free API for non-commercial use – which any organization can download and use from here: http://resources.esri.com/arcgisserver/apis/flex/. Additional widgets are available from the code gallery here: http://resources.esri.com/arcgisserver/apis/flex/index.cfm?fa=codeGallery.
Thanks to Carmelle Terborgh for the details.
