If I add alias (directory with same tiffs) to datasource, map is displayed correctly. I tried to add geo tiff or ecw via composite mode it loses coordinate information to. I was thinking it is problem with world files, but it seems that it is problem in gdal, mapguide maestro or MGOS. <br>
Any Ideas how to solve it?<br><br>P.S. I tried to add tiles data vie php script found in FDO website (rasterconfig.php). same problem too... :(<br><br><br><div class="gmail_quote">On Thu, Jun 12, 2008 at 6:30 PM, Kenneth Skovhede, GEOGRAF A/S <<a href="mailto:ks@geograf.dk">ks@geograf.dk</a>> wrote:<br>

I have seen this happen when the images are not accepted by GDAL.<br>
For some reason it does not return an error, but rather some large
values.<br>
<br>
What happens if you try to use a single file (ea. not composite mode)?<br>
Do you get the correct coordinate system?<br>
<br>
If not, you can try to debug with the regular raster debug guide:<br>

I think I'm missing something basic here. Why world files are not detected?
If I add same data using alias, everythink works fine.

<pre>I don't think re-installing Maestro will help.
AFAIK MapGuide needs two setups for coordinate systems, one for MapGuide
and one for the WebTier.
Maestro only has access to the WebTier, so everything may work fine, but
you cannot see the coordinate systems.

<pre>Odd, since it's been working fine all along....I'm going to try
reinstalling Maestro. As for my image layer - I've managed to get it
to show up now, but it's totally crazy. If I do a layer preview in
Studio, I see a single image - should be about 6....and it's scale is
messed up, because I have to zoom way way out to see it.

<pre>Ah. Easy....thanks! Now when I did that, of course, my coords system
overrides got messed up and I can't seem to fix them from Maestro
(or anywhere, so far) - In Maestro, all I get in my coord category
list is Arbitrary X-Y....If I just paste in the correct string,
it'll take it - but every time I refresh my overrides, it adds a
Default in XY-MT. If I look at the configuration document using
Studio, I see that it's got some coord system stuff in it (in
<fdo:WKT>), and that it's wrong (it's using XY-MT). I'm guessing
this is the problem, but have no idea how to fix it. Here's that
section in the configuration doc:
<gml:baseCRS>
<fdo:WKTCRS gml:id="Default">
<gml:srsName>Default</gml:srsName>
<fdo:WKT>LOCAL_CS["*XY-MT*",LOCAL_DATUM["*X-Y*",10000],UNIT["Meter",

In the "Type" field select "Composite".
Now add files and folders in the list below.

<pre>The Gdalnotes wiki says:
"With the release of FDOGDAL 3.2.3, Frank has added support for
tile indexes in an XML config file.
MapGuide Maestro <a href="http://trac.osgeo.org/mapguide/wiki/maestro" target="_blank"><http://trac.osgeo.org/mapguide/wiki/maestro></a>
will allow you to create these tile indexes in an intuitive GUI."
Where do I find that gui?
