North Carolina Landslide Hazards

This amazing video has been making its way around the geoblogosphere as well as the mainstream media. Pretty remarkable. It ranks up there with the Japanese Landslide Video.

A report has been released by the NYSDOT on the Scoby Hill Landslide which has impacted a 4.2-mi improvement project of Route 219. The report, dated May 20, 2008 was headed to an FHWA peer  review panel.

The Feds were call in to help because of the unusual nature of the landslide. The slip surface is very deep, approximately 30-m (100-ft) below the surface and below all of the design phase investigations. And the remolded shear strength of the silty clay forming the slip surface was only 12-14 degrees.

From Google Maps Mania Blog:

The ArcGIS JavaScript Extension for Google Maps allows map developers to extend the Google Maps API to use ArcGIS Server services. With the extension, you can add your own data to a Google Map and embed this map in your own page.

ESRI have a number of examples of what can be achieved using their new API. Examples and reference for the API can be found here. Using the API you can:

• Display your own maps on top of a Google Maps base map.
• Execute a GIS model and display the results in Google Maps.
• Search for features in your GIS data and display the results on Google Maps.
• Find addresses using your own address locator and display the result on Google Maps.
• Display attributes from your GIS data on the map using the Google Chart API.
• Allows others to add GIS functionality from your server as a Google Mapplet.

On the surface, it seems like this news would only be of interest to GIS professionals and geeks like me. But the truth as I see it is that this development for extending the popular ArcGIS platform to the internet will lead to a whole host of new online applications and mashups that will be both fun and useful.
