<h2>What is FOSS?</h2>

<h3 style="margin: 1em 0;">Free and Open Source Software</h3>

<ul>
    <li style="margin: 0.5em 0;">Software that is free to run, study, modify and distribute
    <li style="margin: 0.5em 0;">Free means freedom: free is a matter of liberty not price
    <li style="margin: 0.5em 0;">It can be commercial but not proprietary
</ul>
</section>

<h2>FOSS is everywhere </h2>

<blockquote>
<p>
Microsoft loves Linux
<p>
&mdash;<a href="http://www.theregister.co.uk/2014/10/20/microsoft_cloud_event/">Satya Nadella, Microsoft CEO, 2014</a>
<!--Neil McAllister, The Register, October 20, 2014-->
</blockquote>

<blockquote>
<p>
Apple uses software created by the Open Source community and returns its enhancements to the community.
&mdash;<a href="https://www.apple.com/opensource/">Apple Inc., 2015</a>
</blockquote>
<p>
Google, Amazon, Facebook, IBM, Red Hat...
all use and contribute to FOSS and the community

<h2>FOSS is essential in science</h2>
<blockquote>
    <p>
        Software [...] developed as part of novel methods is as important
        for the method's implementation [...]
        Such software [...] must be made available to readers upon publication.

<p class="small">Note: making software available to readers does not make it FOSS</p>

<h2>Course development</h2>
<h3>Software and GIS education problem</h3>
<p>
<ul>
    <li>students are becoming software users instead of scientists
    <li>students confuse software implementation issues with fundamental concepts
    <li>bonding with single software limits flexibility and broader knowledge of the field
</ul>
</section>


<section>
<h2>Beyond teaching GIS software</h2>
<ul>
<li style="padding-top: 0.5em;"><b>Lectures:</b> software-independent, focus on theory, concepts
<li style="padding-top: 0.5em;"><b>Assignments:</b>
    <ul>
        <li>hands-on practice related to lecture topic
        <li><b>students use two different software packages solving similar tasks in both</b>
        <li>opportunity to see what is a general concept
            and what is specific to a particular software
    </ul>
<li style="padding-top: 0.5em;"><b>Independent project:</b>
    focus is on research question, students chose software/tools/data
</ul>
</section>


<section>
<h3>Geospatial Analysis and Modeling course</h3>

<ul>
    <li>offered since 2008 as on-campus and distance course
    <li>every semester 30-50 students
    <li>assignments in <b>both</b> GRASS GIS and ArcGIS
    <li>workflow for each software is provided
    <li>students write papers explaining methods and results
</ul>

<h3>Keeping assignments up-to-date</h3>

Most of the assignment instructions provided as text (easy to update), 
students generate the images.
<ul>
    <li>GRASS GIS workflows provided as commands.
    <ul>
        <li>GUI dialog filled according to the command.
        <li>Commands can be automatically extracted and tested.
    </ul>
    <li>Text also for running ArcGIS part through GUI, 
        but the names in dialogs are not part of the API, so they change.
</ul>

<h3>Standardized sample datasets</h3>

Initiative to make the course material location specific through data sets with standardized names of layers

r.relief input=elevation output=shade
d.shade shade=shade color=elevation
</code></pre>
