<div>Hi, Sorry if this has been addressed before, I couldn&#39;t see any way to search the archive.</div>
<div>&nbsp;</div>
<div>I want to build the correct paramater list for proj based on this data:</div>
<div>PROJCS[&quot;NAD_1983_UTM_Zone_12N&quot;,GEOGCS[&quot;GCS_North_American_1983&quot;,</div>
<div>DATUM[&quot;D_North_American_1983&quot;,</div>
<div>SPHEROID[&quot;GRS_1980&quot;,6378137.0,298.257222101]],</div>
<div>PRIMEM[&quot;Greenwich&quot;,0.0],</div>
<div>UNIT[&quot;Degree&quot;,0.0174532925199433]],</div>
<div>&nbsp;</div>
<div>PROJECTION[&quot;Transverse_Mercator&quot;],</div>
<div>PARAMETER[&quot;False_Easting&quot;,500000.0],</div>
<div>PARAMETER[&quot;False_Northing&quot;,0.0],</div>
<div>PARAMETER[&quot;Central_Meridian&quot;,-111.0],</div>
<div>PARAMETER[&quot;Scale_Factor&quot;,0.9996],</div>
<div>PARAMETER[&quot;Latitude_Of_Origin&quot;,0.0],</div>
<div>UNIT[&quot;Meter&quot;,1.0]]</div>
<div>&nbsp;</div>
<div>I&#39;ve read the documentation, and since I&#39;m just a newbie to cartography it is all still&nbsp;a little unclear and I need to learn by example.</div>
<div>&nbsp;</div>
<div>Is there any code out there (any language) I could see that takes this kind of input and builds out the paramaters for prj_init()?</div>
<div>&nbsp;</div>
<div>My guess is that it is something like this:</div>
<div>static char *params_in[] = { </div>
<div>&nbsp; &quot;proj=tmerc&quot;, </div>
<div>&nbsp; &quot;lat_0=0&quot;, </div>
<div>&nbsp; &quot;lon_0=500000&quot;, </div>
<div>&nbsp; &quot;units=m&quot; </div>
<div>};</div>
<div>prj_init(4, params_in);</div>
<div>&nbsp;</div>
<div>But that doesn&#39;t work :)&nbsp; And I&#39;m sure it is pretty far off.</div>
<div>&nbsp;</div>
<div>Thanks.</div>
