I have posted you my latest correction curves for MicroDEM.  It will change the greyscales  of the SRTM files so IL2 will plot the heights properly, albeit with the limitations of the terrain engine.  m properly.  It also allows you to assign textures to the maps automatically and then tweak them later.  Instructions are below.
 
 
Run MicroDEM and do the following:
 
Load your SRTM map, once loaded do the following:
 
To set the correction curves and display to greyscale:
 
menu:
	"modify"
	"elevation"
	Select "colours from table"
	Then select the "Elevation Table" button
	Load the new table values I have sent
	Select the "Missing" button
	Choose red as your colour
	Press "OK"
	Ensure "Ocean Check" and "Lake Check" is not ticked
	Press "OK"
 
You should now have a greyscale piture and possibly some red areas.  The red shows missing data, to get rid of this do the following:
 
select from the menu:
 
	"EDIT"
	"DEM Holes"
	"Interpolate across holes (Smooth)"	(default value is 2, I use 5)
	Select "OK"
	select "Yes"
 
You may have to experiment with this.  Choose a value, the larger the number the larger the "hole" is filled.  I sometimes have to use up to 5 or 6 as the number.
 
Now to set the scale, go to menu:
 
	"Modify"
	"Map Area"
	"Set Map pixel size"
	since we are making a map_h, change the value to "200.0" and press "OK"
 
Now to save the map: go to menu:
 
"File"
"save image"
 
I always save as a BMP image then edit and crop in Gimp.  For assigning textures etc , the principle is the same, just use the terrain textures colour scale instead.
 
You can open both files in a spreadsheet to look at and edit the values.
