Simple question about scalebar.

[Dirk-Jan Huisman]

Hi,
 
The units of the projection is m. The Extent of your mapfile are m? If
it is, the units of the mapfile should be m.  
 
best regards

Hi,
 
Thank you for your response. My map file is simple as below:
 
MAP
 SHAPEPATH "d:\work\gis\kornburi\data\"
 FONTSET "./fonts/fonts.list"
 SYMBOLSET "./symbols/symbol.sym"
 EXTENT 730000 1550000 935000 1750000
 UNITS kilometers
 SIZE 600 450
 IMAGETYPE gif
 TRANSPARENT on
SCALEBAR
 POSITION ll
 STATUS off
 COLOR 255 0 255
 IMAGECOLOR 255 255 0
 UNITS KILOMETERS
 INTERVALS 3
 STYLE 0
END
PROJECTION
    "proj=utm"
    "zone=47"
    "a=6377276.345"
    "b=6356075.413"
    "towgs84=209,818,290,0,0,0,0"
    "units=m"
    "no_defs"
END
LAYER
...
...
END
 
My problem is that scalebar showed wrong distance. Everything is ok but
scalebar. I told you last message that true distance it should be 18.3
km but scalebar showed 18300 km. I thought if this number was correct,
then the unit should be meter not kilometer.

Hi,
 
It's not clear what goes wrong. Include some code of your mapfile. What
are the map units and the scalebar units?

Dear all,
 
Whether or not I embeded scalebar in map, it showed wrong distance, e.g.
it should be 18.3 km but it showed 18300 km. Nontheless I use projection
or not. What I have to specially set to get right scalebar?
 
TIA
 
Krung
