Hi Shwetha,
 
Here are the answers,
 
1.  MSE provides APIs for retrieving the building maps. What is the format of these images? Are these images in JPEG or   
    AUTOCAD images?
 
  - WCS is used to load the image maps which will be pushed into the MSE . Image format supported in WCS are JPEG or JPG
    or GIF or PNG . One can also import CAD maps DXF,DWG but in this case WCS will convert these maps to PNG format and
    pushes to MSE . So when you retrieve from MSE APIs it will be either GIF or JPG 0rJPEG or PNG    .
 
2. Does MSE store multiple building map images for different zoom sizes?
    
   - No , Only one single image for a floor , one has to write their own logic to show the zoom in/out effects . WCS has
     the capability to dispaly all these effects .
