Here is an example:

; Set GeoTiff geotags: http://www.remotesensing.org/geotiff/spec/contents.html
s_geotag = {$
MODELPIXELSCALETAG: [d_resolution, d_resolution, 0], $ ;resolution
MODELTIEPOINTTAG: [ 0, 0, 0, d_xL, d_yA, 0], $ ;coordinates left
above
; GEOGGEODETICDATUMGEOKEY: 6326, $ ;geodetic datum WGS84
GTMODELTYPEGEOKEY: 2, $ ;Geographic latitude-longitude System
GTRASTERTYPEGEOKEY: 1, $ ;raster type
GEOGRAPHICTYPEGEOKEY: 4326, $
; GEOGLINEARUNITSGEOKEY: 9001, $ ;linear unit meter
GEOGANGULARUNITSGEOKEY: 9102} ;angular unit decimal degree

;write 16-bit geotiff - data 16 can be 3D matrix - dimension 1 for
channel, D2 for columns, D3 for lines
write_tiff, 'output_16b.tif', data16, compression=1,
geotiff=s_geotag, /float

Hope it helps!
