Update improves performance of NoCal LiDAR browsing in Google Earth

Feb 6, 2009

We are pleased to announce an updated version of the Northern California GeoEarthScope LiDAR in Google Earth capability that offers significantly improved browsing performance. This update features the same data as available in previous releases but achieves faster data loading in Google Earth through an updated image processing approach. In order to experience the improved performance it is necessary to download a new KMZ file.

Introducing the OpenTopography Portal

Dec 3, 2008

Yesterday, GEON released an updated and redesigned website (http://www.geongrid.org/). As part of the update to the GEON site, we have moved all of the LiDAR topography oriented features previously hosted in the GEON portal to a new website we are calling the OpenTopography Portal (http://opentopography.org/).

Garlock LiDAR data is now available: GeoEarthScope SoCal airborne LiDAR project

Nov 25, 2008

Another round of GeoEarthScope LiDAR data is now available via OpenTopography. The much anticipated Garlock fault portion of the Southern & Eastern California acquisition can now be downloaded via OpenTopography in Google Earth hillshade overlay and standard tiled DEM formats. The full data release announcement:

We are pleased to announce the availability of new GeoEarthScope airborne LiDAR data products from the Southern/Eastern California project! This release includes full coverage of the Garlock fault.

LiDAR data update: NoCal Hillshades in Google Earth

Nov 12, 2008

David Phillips, GeoEarthScope Project Manager, distributed an email announcement today about the Google Earth Northern California GeoEarthScope LiDAR hillshades that are available via OpenTopography:

OpenTopography Beta Release

Nov 7, 2008

We are pleased to announce the beta release of the OpenTopography Portal. We are still actively working to refine the user interface and navigation, and add content to the pages, but the core functionality of the system is ready and stable. For those of you that have used the GEON LiDAR Workflow running inside the GEON Portal, OpenTopography will be familiar.

Chaitan Baru to Present at 4th Annual Topo-Europe Meeting

Sep 23, 2008

The 4th International Topo-Europe Meeting will be held October 5-7, 2008, in Madrid, Spain. The aim of this meeting Is to provide an open forum for science on the feedbacks between deep Earth and surface processes. Chaitan Baru will attend and present a talk on GEON, on October 6th.

Northern California GeoEarthScope LiDAR Hillshades in Google Earth

Sep 23, 2008

GEON, in collaboration with the USGS, has developed a Google Earth file (KMZ) that provides access to 1 meter resolution bare earth hillshades from the Northern California GeoEarthScope LiDAR topography dataset. By downloading this file and opening it in Google Earth, users are able to browse hillshades with two illumination angles (315 and 45 degrees) for faults in the northern San Andreas fault system. The Google Earth file remotely accesses data stored on GEON servers to allow users to seamlessly browse the full NoCal dataset from within Google Earth.

GeoEarthScope Northern California Airborne LiDAR Data Available for Download

Aug 20, 2008

The entire San Andreas fault system has now been imaged utilizing GeoEarthScope Northern California Airborne LiDAR Data, along with many other important geologic features, and is available for download via the GEON Portal. This entire dataset is now available as 1 km^2 tiles of 0.5 m digital elevation models - both unfiltered (all data)and filtered (bare earth) in ESRI (ArcGIS) binary grid format. Complete metadata are also now available for download.
