LiDAR, acronym for Light Detection and Ranging is a remote sensing technique to capture precise elevation including any vegetation or buildings on the earth’s surface. Over from the Lidar News blog is a short video from the Department of Geosciences at Idaho State University, introducing the principle of LiDAR and its application in elevation modeling of Snake River, Swan Valley in Idaho.
With all the rave reviews that Ubuntu 10.04 Lucid Lynx has been getting over the past couple of months, I couldn’t help myself upgrading and checking out the exciting new features and the enhanced interface, which I think was a much needed overhaul for the best desktop Linux OS.
A new version meant fresh installation of all the open source GIS goodies starting with QGIS. The latest version 1.4.0-Enceladus for Lucid is already available in the Launchpad UbuntuGIS repository and with a new command (add-apt-repository) for updating /etc/apt/sources.list with locations of repositories, the installation is simple and straightforward.
Bring up the terminal and issue the following commands.
Add the repository using:
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
Make apt aware of the new repository:
sudo apt-get update
Install QGIS
sudo apt-get install qgis
Once the installation is done, open QGIS from Applications -> Science -> Quantum GIS
This week marked the end of the 2010 ESRI Worldwide Business Partner Conference (BPC) and the 2010 ESRI Developer Summit at Palm Springs, California which was host to the largest gathering of GIS developers.
The BPC set the tone for the Developer Summit by showcasing features of the upcoming release of the ArcGIS product suite – ArcGIS 10. For those of us who couldn’t get to attend and see the demos first hand, the Plenary Session videos have been made available for viewing which cover the following topics:
ArcGIS.com
Desktop Usability
Server and Web Clients
Mobile Platforms
Editing Improvements
Imagery Platform
Analysis
Business Analyst Online
ArcLogistics
ArcGIS Server on Amazon
What started off as an overview of ArcGIS 10 during the BPC was picked up at the Developer Summit with demonstrations delving more into the new features and enhancements that ArcGIS 10 is going to support. ESRI has been quick to upload the Plenary demos which cover the following topics:

Jithen Singh on his blog http://geo.geek.nz has a detailed write-up summarizing the Plenary Session events of the Developer Summit.
The proceedings include code demonstrations and presentations (slides and video) by the EDN team and ESRI users for
Among the GIS blog world, this is the fourth posting today on ESRI’s official YouTube channel.
It so happens that many of the videos uploaded on YouTube can also be found on Viddler, probably uploaded by the same professionals. Just in case you happen to have problems accessing YouTube, don’t’ panic and remember that there’s Viddler.
