[mapguide-users] Additional FDO Provider Previews

[Andy Morsell]

Should the <Location name= tag point to the path or the full file name in
the case of a MrSID image?  If just a path, should there be a slash at the
end?

For a raster resource, there will (unfortunately) be an extra step of
indirection from what I posted originally for SHP and SDF files. Most of the
feature information for a raster is stored in a separate XML file which the
feature source points to. Basically the feature source looks like this:
 
<?xml version="1.0" encoding="utf-8" ?> 
<FeatureSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
  <Provider>Autodesk.Raster.3.0</Provider> 
  <ConfigurationDocument>config.xml</ConfigurationDocument> 
</FeatureSource>
 
 
Note how it points to config.xml -- this file is also stored as a resource
associated with the raster feature source, so you need to call the
GetResourceData operation with config.xml as argument. config.xml contains
the location of the directory where the raster is and then lists the raster
you actually want to include in this feature source. So you can edit it
similar to what I suggested for SHP and SDF and save it back to the
repository using SetResourceData.
 
An example config.xml is attached. The disclaimer here is that unlike SHP
and SDF, I did not actually verify that this process would work without
problems for the raster provider.

Have you looked at using this procedure to create resources with external
locations?

&msgNo=321
 
When I have time, I'm going to write either a web app or command line
utility that allows us to do this for SHP/SDF (and other?) resources.  I may
need to work on figuring the right XML schema for the new data sources...

I've been playing with the raster provider this morning and am happy to
report that two quick tests worked fine and performance seems to be very
good.  I loaded up a 10 MB ECW and a 250 MB MrSID.  The flexibility of
transparent shaded polygon fills really shows over raster, it's very nice.  
 
My only complaint is the managed data structure of the repository.  I had to
load my MrSID which already resides somewhere else on that same drive and is
accessed by other apps (like an older MapGuide 6.5 app).  Now I have
redundant data.  Are there any plans to allow "connections" to raster data
stored in other physical locations?  I have some clients that have many
gigabytes of imagery used in their existing MapGuide applications and I see
having to load the data as a potential problem.

All,

 

Previews of the additional FDO Providers for ArcSDE, MySQL, ODBC, WMS, WFS,
and Raster Files have now been posted for the Windows platform only at this
point. You can download individual providers from:

 

 
<https://mapguide.osgeo.org/servlets/ProjectDocumentList?folderID=35&expandF
older=35&folderID=35>
https://mapguide.osgeo.org/servlets/ProjectDocumentList?folderID=35&expandFo
lder=35&folderID=35

 

Note that the included Raster Provider is the one that will be shipped with
the commercial MapGuide offering. If you only intend to use the Open Source
version then Franks GDAL Provider is the one you will want to use long term.

 

See the readme.txt file included with each provider package for installation
instructions.

 

Thanks,

Bob
