I have a raster image ( DEM fromat from US Geological survey).
This format has x,y, z(elevation data). If I want to display it in the Web,
I have to convert it to GIF/JPG formats. In doing so, I will loose the z's values which I need
to use in my calculation in Java or whatever. Is there a way to convert the DEM format to
GIF but still keep the all the z values. I see on solution is to save he z values in a text
file but in this case java will take too much time to download it and interact with it
once it is loaded. I am looking for a solution. I am prepared to do whatever to find a
solution to this problem. If you know, please let me know please. Thanks
