I went through the Image Tutorial in http://docs.geotools.org/stable/tutorials/raster/image.html and was able to load image and get the output.
But I need to load the image without use of world file format, since I need to load image dynamically.
Also if that is not possible, how do I load image(say base station image) instead of points in countries. Eg: I need to load images in the point which points on Australia and Africa. How it can be done?
Thanks in advance
