<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Thanks for the suggestions. I am able to reproject my maps with mapserver. I found out what projection my maps started in by reprojecting in QGIS, it filled in the starting projection. Either it calculated what that projection was, or it was the default. Then, wherever my site modified coordinates in the mapfile, I used cs2cs to convert meters to degrees first. Alaska wraps so I had to change starting longitude to -40. All works good now! <br><br>--- On <b>Tue, 8/24/10, Fawcett, David (MPCA) <i><David.Fawcett@state.mn.us></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: Fawcett, David (MPCA) <David.Fawcett@state.mn.us><br>Subject: RE: [mapserver-users] projecting in degrees<br>To: "Josh Jordan" <outerspaceman81@yahoo.com>,

units of the utilized by the SRS are inherently part of the definition. When
data is projected to a particular SRS, the units are set by that SRS. </span></p>

defining input projections for your layers and an output projection for your
map. Your annotation layer could be in geographic coords and the
annotation points would be projected by MapServer.</span></p>

<p class="yiv1294213289MsoNormal">I have shapefiles that are stored in degrees and they are
displayed in degrees if there are no projections in the mapfile. When
displayed like this, they look like UTM world projection. However, I
need to display it in old style mercator where greenland is really big.
I can get mapserver to project as mercator, but it always converts to
meters. I would like to project my shapefiles in degrees. Is this
possible? I need to because I handle extents and annotation points in
degrees.</p>
