GIS Training book done!

Monday, June 9th, 2014

We’ve finished the learning GIS via QGIS  book and it is in the process of publishing.  We’ll let you see the pre-design cover and tell you that it will be available on AMAZON soon!

The authors are Nik Freeman and McCartney Taylor. (Note: the important author goes last)


The book is a workbook that evolved from our training courses over 3 years. It will be aimed at the beginner, walk them through important concepts, then give them data and start using QGIS to make a map.  The formula was very successful in training hundreds of Oil and Gas people in how to use basic GIS. And it saved thousands of dollars by showing them how they can use the free QGIS instead of ESRI.

Expected release date June 30, 2014.


Solving Issues Downloading Qgis for Ubuntu 13.04

Wednesday, July 17th, 2013

I downloaded Qgis for Ubuntu 13.04 and I encountered a few issues.

First issue I had was that I was not able to download any plugin-ins. Second issue is that I was having is that I was not able to download and use the sextante plugin after solving my initial problem.

Before starting I would do a clean install of Qgis if you have been having problems

sudo apt-get purge qgis

If you having issues downloading plugins:

I found this tutorial online and it is from a few years ago but the step to remove the directory worked for me.

Change to your home directory in the terminal, if you need help with the terminal see the Ubuntu documentation 



ls -la

sudo rm -Rf .qgis


What these commands will do is delete a read only file that is put on your computer during installation preventing you from being able to download plugins. There is a more detailed explanation in the link.


To download the sextante plug-in:

If you want to use all the parts of the sextante plugin, make sure you have grass installed: and make sure you have SAGA installed. You can get SAGA from the software center or online

If you are getting the error that you are missing psycopg2 you have two options

First try and download it from the software center

Then in the terminal:

sudo apt-get update

Then open up Qgis and see if you are able to get the plugin.


If this does not work for you and when you try and download from the software center it give you an error then here is the process to get around that

In the software center look for the synaptic package manager

What is allows you to is download any updates or repositories needed as a sudo user with a GUI interface

In the search box look for the update: I just typed psy and it came up in the list

Click on it, check mark for installation and then Mark all upgrades


Then in the terminal

sudo apt-get update

Then open Qgis and the plugins should be available.

Free Mapping Software

Monday, August 9th, 2010

We, at the Institute, are big believers in free mapping software.  Open Source has brought wonderful software tools to the common man who lives on a tight budget. There is no need to spend hundreds of dollars (or thousands if buy ESRI) on  GIS software if you are a beginner .


The best software for the beginning and intermediate mapmaker is Quantum GIS, aka QGIS. It is intuitively easy to learn, powerful in capabilities, yet friendly in use.

Best yet, they update it constantly, and that costs you nothing. You got it — zero, zilch, nada.  And as you grow as a cartographer, QGIS can keep up with you until you begin extremely advance GIS processes.


The folks at QGIS  have just come out with version 1.5, and it has wonderful features.  So good, in fact, that we use it for our Professional  Education Training and other GIS courses.  It beats out the other two contenders, GRASS, and gvSIG.  You can get QGIS here at
