<p class=MsoNormal>Hi Trevor.<br>
<br>
The message reported by Maestro is a warning, because it can see that the
extents are invalid.<br>
I think 2.0.2 returned the correct bounds, so perhaps a change after that
resulted in this problem.<br>
IIRC, the coordinate system was also returned correctly in 2.0.2.<br>
<br>
In 2.0.2 (and 2.1), the XY-M and default extents was returned by the provider
if you gave it an empty folder.<br>
I would think it should throw an error because no files were loaded.<br>
<br>
The config document is optional (afaik) but is created if you use a composite
set of ECW files.<br>
<br>
<br>

<p class=MsoNormal style='margin-bottom:12.0pt'>The GDAL provider is a little
special, in that it never reports errors.<br>
Instead it returns the default extent, as you have in your xml below.<br>
<br>
Sometimes (perhaps an MG bug or a specific format issue?), the default extents
are also<br>
returned for perfectly valid data, making it impossible to detect errors :(.<br>
<br>
The only way to see the data, is to set up a map with the correct coordinate
system and<br>
extents. Then add the layer and preview the map.<br>
<br>
The GDALOPEN message you get means that the file was read correctly.<br>
I'm not sure what aux or HFA has to do with ECW though.<br>
IIRC (90% certain :)), it reports "succeeds as ECW" in my setup.<br>
<br>
The "Value cannot be null" could be the indicator, but since you can
get<br>
the schema, I suspect that it is working anyway.<br>
<br>
In Maestro (the latest preview), there is a bug with the coordinate system
override,<br>
you need to use the "advanced" editor, or the coordsys override is
not set (there is an issue registered).<br>
