yes you have done it like you should , just merge srtm files ( separate maps squares ) into one in microdem ... make all steps you have done .....don't know if you did that as well :

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"
set pixel and export in BMP


after it make map_t (texture) and map_c (land/water)as explained in CW's tutorial and export it as BMP as well .


Open new project in graphic editor ... put all three maps as layers in it .... crop to desired size/area
