Hi All,

I am using Alexander Brenning RPyGeo. I have a DEM.asc (ASCII File format)
and I wish to obtaion SLOPE (possible always in ascii formta) in percent.
But I have this problem:

 rpygeo.Slope.sa
<http://rpygeo.slope.sa/>("C:/work/DEM.asc","C:/work/SLOPE.asc",unit=c("PERCENT_RISE"),
z.factor = 1)
[1] "Executing: Slope C:/work/DEM.asc C:\\work\\SLOPE.asc PERCENT_RISE
1"
[2] "Start Time: Mon Mar 02 19:03:30
2009"
[3] "Failed to execute. Parameters are not
valid."
[4] "Parameter : C:\\work\\SLOPE.asc's extension is invalid for the output
raster format."
[5] "Failed to execute
(Slope)."
[6] "End Time: Mon Mar 02 19:03:30 2009 (Elapsed Time: 0.00
seconds)"
>

I tryed several solutions but nothing. I tryed also with RSAGA but I don't
understand the right code to have in "percent".


Thanks

Gianni.

PS: for Prof. Alexander Brenning. this geoprocessing expression runs in
RpyGEO

rpygeo.geoprocessing("Intersect_analysis"
c("C:/work/plots.shp;C:/work/sample.shp", "C:/work/right_sample.shp",
"ALL"))

but I need to load the datas from the work folder
