Greetings,

   I'm considering implementing a udig website, but have a few questions about 
udig's capabilities:

1.  Does udig support dynamic adding and dropping of image layers?  I have a 
very large area to map, which is covered by about 250 Landsat 30-minute tiles 
in .jpg format with world files.  Clearly I can't load all of these images into
the map at the start.  I need to be able to load only the ones in the user's 
map frame, dynamically, as a user pans or zooms.  Is this possible?

2.  Does udig support digitizing over the web?  I need users to be able to draw
points or polygons on their maps, and have the shapes saved on the server.

3.  Does udig support spatial queries based on irregular polygons that the user
draws on the map?  I need to be able to do this, pulling the spatial records 
out and linking them to a MySQL database.

4.  Does udig support shapefiles?

Thanks,

-Steve
