<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt"><font face="Calibri" size="3">I currently have several XP based laptops running MGOS 2.02 (IIS, PHP) and one server (MGOS 1.2, IIS, PHP). All of the maps on each were authored using Studio and each have a 1.05Gb ECW displaying correctly.</font></p>
<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt"><font size="3"><font face="Calibri">However, I can not seem to get the same ECW to run correctly with MGOS 2.1 on another new XP laptop (IIS, PHP). <span style="mso-spacerun: yes"> </span>I’ve tried using both Studio 2009 as well as Maestro to no avail.</font></font></p>
<div class="MsoNormal" style="MARGIN: 0cm 0cm 10pt"><font face="Calibri" size="3">With studio, I use the GDAL provider and connect to an external data source via a pre-configured alias (C:\Data\ECW_2007). I then select the ECW via the “data files” and then do a coordinate override. When I add the layer using this data source and preview it, nothing appears.</font></div>
<div class="MsoNormal" style="MARGIN: 0cm 0cm 10pt"><font face="Calibri" size="3">No errors show up in the log show up and running in debug mode shows no errors. I only get messages of type: “GDAL: GDALOPEN <C:\DATA\ECW_2007/Cornwall_10cm_20-1.aux, this=0146110> succeeds as HFA” (I think that means no errors...correct?).</font></div>
<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt"><font face="Calibri" size="3">I’ve never used Maestro before, but I think I do everything right there too. I select the GDAL Provider, of “type Single file or folder”, point to my .ecw in the Aliased folder and override the Coordinate System to UTM83-18.</font></p>
<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt"><font face="Calibri" size="3">When I create a layer for this datasource however, I get this message:</font></p>
