[GRASS-user] r.mapcalc-problem

[Helmut Kudrnovsky]

hi,

i test a little bit the examples in

http://skagit.meas.ncsu.edu/~helena/grasswork/grassbookdat07/ncexternal/grasstestrast.txt

on grass64 from osgeo4w on a Win Vista 32 box. 

I copy simply the command from the file above in the command line of the wx-gui

first example:

# find developed areas close to lakes
r.buffer lakes out=lakes_buff dist=60,120,240,500 --o
d.rast lakes_buff
r.mapcalc "developed_lake=if(landuse96_28m==1 || landuse96_28m==2, lakes_buff, null())"
d.rast developed_lake
d.vect streets_wake co=grey
d.rast -o lakes

following error message for the r.mapcalc-command:

(Thu Mar 12 22:32:47 2009)                                                      
r.mapcalc "developed_lake=if(landuse96_28m==1 || landuse96_28m==2, lakes_buff, null())"
syntax error, unexpected $end, expecting '='
Parse error
(Thu Mar 12 22:32:48 2009) Command finished (0 sec) 

second example:

r.mapcalc "streets_travtime=1./streets_speed"
r.info streets_travtime

following error message for the r.mapcalc-command:

(Thu Mar 12 22:34:39 2009)                                                      
r.mapcalc "streets_travtime=1./streets_speed"                                   
syntax error, unexpected $end, expecting '='
Parse error
(Thu Mar 12 22:34:39 2009) Command finished (0 sec) 


best regards
