<div dir="ltr">Hi Johan,<div><br></div><div style>Thanks for the suggestion of tuning the ArcGIS server! It was something that I certainly had not consider. I will gather some information about its feasibility on the client's environment. Just a double check that I understood it: the already existing WMS FDO provider can be used to access raster data in read-only mode by enabling the WMS in the ArcGIS server (which functionality from [1] does it map to? GIS Web Services?), correct?</div>
<div style><br></div><div style>Regarding your second point, I am confused. How would I access to the ArcSDE raster data by extending the FDO ArcSDE driver with GDAL? As far as I understand, the model used in ArcSDE is not GDAL. Could you elaborate this further, please?</div>

<div>* If you have access to the arcgis server it may be reasonably easy to configure a wms (if it is a recent version of arcgis server and the license [1] permits you to do so). Configuring this has the advantage that it can also be used in other applications apart from mapguide and no programming is required.</div>
<div>Apart from that, this solution seems more futureproof. I'm not too sure about the future of arcsde. WMS will probably be supported far longer.</div><div>* If you expand the arcSDE driver in GDAL all applications that use gdal could use the new driver. Actually more people could be testing and/or maintaining your changes.</div>

We are in need of raster functionality with ArcSDE. One of the ways that we are considering (and the most likely) is to extend the existing FDO provider and releasing our implementation back to the community.</div><div style="font-family:arial,sans-serif;font-size:13px">
