[GRASS-user] r.mapcalc error

[Blumentrath, Stefan]

Hei Andy,

You have a whitespace in your mapname, wich is not valid. I am surprised that a mapset name with only numbers is allowed...
The rest looks OK.

Try:
r.mapcalc expression="image1=if( NDVI at 220215  >= 0.25 ,1 ,0)"
instead.

Cheers
Stefan

Hi Helmut,

the r.mapcalc error i found at the first time when i try to mosaic two images. Then I try r.mapcalc in another operation, for example :

r.mapcalc "image 1 = if( NDVI at 220215  >= 0.25 ,1 ,0)"
syntax error, unexpected INTEGER, expecting '('
Parse error
ERROR: parse error

regards,

Andry
