[mapguide-users] GDAL provider for raster...again problem whit loaddata...

[Chris Tallman]

I think you guys having problems with the GDAL provider may have missed
an important post that I can't seem to find either.  But, I think it was
stated at one point that rasters connected using the GDAL would not
preview in studio.  I believe you have to make a map and web layout and
view it with a browser to see the aerial images.

Maybe someone else has this post I couldn't seem to find it on Nabble.
I'm sure it's buried in the posts when 1.1.0 was first released. 

I maybe wrong and if so someone correct me but its worth a try.  I'm
using Windows Server 2003 and have no problems with aerials.

Subject: [mapguide-users] GDAL provider for raster...again problem whit
loaddata...

hello!

i fight (do the end:) whit raster and GDAL provider...what may problem
is.


I download and install MGOS 1.1.0
http://mapguide.osgeo.org/downloads.html

after that i add
MapGuide1.1.0_GDAL_Patch.zip
-----
To verify whether the patch is installed: check the properties of the
three DLLs (GRFPProvider.dll, GRFPOverrides.dll and GRFPMessage.dll),
they will have a Comment property that ends with the string "(3.2.0.26
Patch)".
-----

yes i have it!


provider.xml file have correctry code:

   <FeatureProvider>
     <Name>OSGeo.Gdal.3.2</Name>
     <DisplayName>OSGeo FDO Provider for Raster</DisplayName>
     <Description>Read access to various raster-based file formats. 
Supports georeferenced file-based raster images.</Description>
     <IsManaged>False</IsManaged>
     <Version>3.2.0.0</Version>
     <FeatureDataObjectsVersion>3.2.0.0</FeatureDataObjectsVersion>
     <LibraryPath>GRFPProvider.dll</LibraryPath>
   </FeatureProvider>


i use following steps to add new raster files.


    1.  Start Studio and connect to your MapGuide Open Source 1.1.0
server.
    2. Then do File > New > Data Connection...
    3. In the Connect To Data dialog that comes up, select OSGeo FDO
Provider for Raster, then press OK. An editor that says "Configure a
Feature Resource using the Generic Editor" will display.
    4. In the Connection Properties grid, there is a
DefaultRasterFileLocation property. Click in the value column and enter
the directory where your image files are. On Linux it has the form
/home/thf/myimages and on Windows it has the form C:\myimages.
    5. The configuration of the raster source is now complete, save the
resource and start using it.


then create layer, add to map and use preview in studio...

NOW:

I observe that whit some tif and jpg it does't work ...raster are loaded
but i can't see it.

look on screen

i have this truble whit 7 raster files (3 are displayed correcty :/

for example try load this raster (i can't see it in MGOS)
http://easy3249.easyisp.pl/mapa2.tif
or this
http://easy3249.easyisp.pl/pistas-ortofoto.jpg

Somebody on group said that it can be raster error....so what sould have
raster file that i can show it in MGOS? any header for example?

I think that many off people have this same problem...it looks like GDAL
provider work but whit raster files who have something...so what it is. 
Do you have this same truble whit that?

In another machine i use MGOS 1.0.2 whit Autodesk.raster.provider....it
works great!  I try add this provider do 1.1.0 but whitout any
results...
