Dear all,<br><br>I am using proj.4 as part of PostGIS. Version 1.3.1 of postgis included PRO Rel. 4.5.0, whereas version 1.36 includes PROJ Rel. 4.6.1<br><br>When I transform a coordinate from EPSG:23209 to EPSG:4326 I get the following results.<br>
<br>In Postgis 1.3.1 (PROJ.4 Rel. 4.5.0):<br><br>"POINT(549556.009066526 4801796.3531214)";"POINT(-8.38839299999999 43.3657910268222)"<br><div id=":151" class="ii gt"><br>In Postgis 1.3.6 (PROJ Rel. 4.6.1):<br>
<br>"POINT(549556.009066526 4801796.3531214)";"POINT(-8.38839299999999 43.3666118995462)"</div><br>The second coordinate of the transformation to 4326 changes by 0.004 degrees (approx).<br><br>If I use cs2cs from command line (version proj446_win32), I get:<br>
<br>-8.38839300 43.36661190<br><br>Why do I get a different result in postgis 1.3.1 and in postgis 1.3.6?<br><br>Why do I get the same result in PROJ4 4.4.6?<br><br>I do not understand. I hope anybody can help me.<br>
<br>Best regards,<br> Miguel<br><br>
