What I am trying to do is get the extent of my data which is on SRS:28355 and convert it too SRS:4326 so my map will display correctly.<br><br>I used the command<br><br>proj +proj=longlat +ellps=WGS84 +datum=WGS84 <geogdata.txt
>results.txt<br><br>but it returned <br><br>+proj=latlong unsuitable for use with proj program<br>
