<P> I think using external Image Web Server is another idea (Example <STRONG>ER Mapper Image Web Server -But Expensive</STRONG> ) and can use layers as <U>OGC WMS</U> ,another option is use the ECWP protocol for providing realtime roam and zoom functionality on image updates. </P>
<P> </P>
<P>Many applications natively support <STRONG>ER Mapper’s streaming imagery protocol</STRONG>.But till <STRONG>now its now supported in MapGuide</STRONG> and if someone can think on those aspects then it can solve integrating High Performance Image Web Server with MapGuide,so in this case the Raster Data will reside on Image web server while vector data on the Mapguide Server.<BR></P>
