<div>guys,<br>trying to put a geotiff in- works but not right. here's what's happening:</div>
<div>
<p>i download the geotiff from national atlas. when i give no proj info under LAYER it shows up but not where it should (nwis). so i copy MAP proj to LAYER proj hoping for some on-the-fly magic- again it shows up but nwis.
</p>
<p>well i go over to <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.remotesensing.org/geotiff/proj_list/" target="_blank">proj_list</a> and look up the epsg (EPSG?) code (9820) from metadata but it throws the "msProcessProjection(): Projection library error. no options found in 'init' file" error. then i try all epsg codes given by gdalinfo ;) but same error. although when i try the MAP epsg code (4326) it shows up but nwis.
<br> <br>so what's wrong here? think proj.exe geod.exe cs2cs.exe libgeotiff listgeo'd help? now i don't think wld is needed because it's included with the geotiff but i've tried with wld and no luck. i just hope i don't have to rectify in arcmap. btw IMAGETYPE=png24 in case that matters.
