QGIS How To’s

Sriharsha Vankadara — Fri, 06 May 2011 20:33:17 +0000

Underdark at Free and Open Source GIS Ramblings reports of a great new addition to the QGIS Wiki – a set of step by step tutorials complete with graphics and categorized into tasks dealing with vectors, rasters, map projections, spatial analyses, format conversion and map making. This is a great reference for anyone just beginning to get their feet wet as well as for existing users trying to get a glimpse of the latest features.

What is LiDAR?

Sriharsha Vankadara — Fri, 07 May 2010 21:48:04 +0000

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.

Install Quantum GIS 1.4.0 on Ubuntu 10.04 Lucid Lynx

Sriharsha Vankadara — Sun, 02 May 2010 01:44:28 +0000

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 video has been doing rounds in the social media circles for some time now and is definitely worth the time. Watch the Fuhrer rant over the failure of ESRI and ArcGIS.

ESRI Videos on YouTube and Viddler

Sriharsha Vankadara — Wed, 01 Apr 2009 21:52:00 +0000

Among the GIS blog world, this is the fourth posting today on ESRI’s official YouTube channel.

ESRI operates a channel on YouTube under then name esritv which is a useful resource with videos on product demos, conference presentations, howto’s, process work flows and other interesting stuff.

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.
