Blue/red color map

is specified by editing to

;mapname="LR BkBlAqGrYeOrReViWh200" ; rainbow style,  nv <= 17
mapname="LR BlWhRe"                 ; blue/white/red, nv <= 17

NRL color map

is specified by editing to

;mapname="LR BkBlAqGrYeOrReViWh200" ; rainbow style, nv <= 17
mapname="nrl_sirkes"                ; NRL,           nv <= 17

Gray-scale color map

is specified by editing to

;mapname="LR BkBlAqGrYeOrReViWh200" ; rainbow style, nv <= 17
mapname="gsdtol"                    ; grayscale,     nv <= 17

It may be an idea to change the color of land here...
