I'm not sure it's the best way but:
1. open in gimp the full uncompressed water map let's say Mymap_c.tga. Select all regions with color around rgb=0 (water), copy (I think you need to have antialiasing unchecked)
2.open map_h.tga and paste
3. fill the layer with black RGB=0 (so the gray colors are all converted to black which means height 0)
3. go to layer and scale down 4 times in both dimensions, with "none" for the scaling method.(if the layer is say 400 by 200 pixels then you scale it to 100 by 50 pixels)
4 move the layer till you get the right position
5. anchor layer
6. save as with RLE compression unchecked
You may then still have problems which you have to correct manually but maybe Redwulf,s utility can do the job automatically...
To no 4.
If My map_c has water in the lower left corner then getting the right position is just moving the scaled layer till it's lowere left corner matches the lower left corner of the whole image (map_h)
And so on, you'll find the way
