<p>Wiki-DavidLARall: m</p> <hr /> <div>David Lloyd Arthur Rall b. 1959 d. not yet <br /> <br /> First program written in FORTRAN in 1973. I wish I had saved a listing of the source. It was a cute little crew race that used &quot;&amp;lt;&amp;lt;&amp;lt;&amp;lt;&amp;lt;&amp;lt;&amp;lt;&amp;lt;&quot;, &quot;||||||||&quot;, and &quot;&amp;gt;&amp;gt;&amp;gt;&amp;gt;&amp;gt;&amp;gt;&amp;gt;&amp;gt;&quot; in succession to emulate an &quot;eight&quot; rowing its way across the screen. In a pathetic way this was a graphical representation of a river with some boats. <br /> <br /> Latest programming work includes a satellite orbit propagator (Simplified General Perturbation model SGP4) and a 3D Earth visualizer (C++, OpenGL, WGS-84). Somewhat similar to the AGI Satellite Tool Kit. I freely admit to some pseudo plagiarism of the style of their GUI. <br /> <br /> I currently work and live in the Washington, D.C. area for a smallish company that does contracting for various government agencies.<br /> <br /> &quot;http://wiki.osgeo.org/wiki/David_Rall&quot;<br /> <br /> &lt;tt&gt;[[Category:OSGeo Member]]<br /> <br /> {{#umAdmin: DavidLARall}}</div>
