<p>Try downsampling your image and using that for your overview map</p>
<p>1.5gb to a tiny little map is a lot of processing... ie like for say a 5k image result</p>

The raster data consist of a geotiff image and its size is 1.5 GB and resolution is 2.5m color. Using openlayers map control it is displayed on the webpage. I have also added the overview map control. But the problem is, it is not sychronized with the map control i.e the overview map control does'nt show the area which is displayed in the map and it is also taking time to display it. Some body point me in a right direction how to sort it out.<br>
