Greetings
I have created a raster with the r.grow function where I attributted
value 1 to the original+growned areas.
From the r.info I obtain the following:
|
|
| Type of Map: raster Number of Categories:
9 |
| Data Type:
CELL |
| Rows:
6991 |
| Columns:
8171 |
| Total Cells:
57123461 |
| Projection: UTM (zone
-24) |
| N: 9305500.00000001 S: 9095770.00000001 Res:
30 |
| E: 689130 W: 444000 Res:
30 |
| Range of data: min = 1 max =
1 |
|
Comments: |
| r.grow input="myscript.tmpcl...@national" output="grow02" radius=1
m\ |
| etric="euclidean" old=1
new=1 |
Where I obtain this:
506505.949964|9267207.442575||1|grown cells
or
506782.475461|9265066.600014||*| for the non-grown values
Then I applied this expression:
if( gro...@national ==null(),1,0)
but from this output I obtain only NULLS. Maybe this is a problem
related with the output of r.grow. can anyone give me a clue?
Thanks
Antonio
