     Type:  defect                     |     Status:  new
 Priority:  normal                     |  Milestone:  7.1.0
Component:  Raster                     |    Version:  svn-trunk
 Keywords:  interpolation, e.surf.idw  |        CPU:  x86-64
 Platform:  Linux                      |
---------------------------------------+-------------------------
 However '''r.surf.idw''' won't make the interpolation for my dataset, I
 tested on NC sample dataset where it was ok. ??

 I was not able to reproduce it with any other dataset but mine. I've
 created a cut of my data and accessible in the next comment.

 Projection: UTM 48N / WGS84 (on the area of Cambodia)

 +proj=utm
 +no_defs
 +zone=48
 +a=6378137
 +rf=298.257223563
 +towgs84=0.000,0.000,0.000
 +to_meter=1

 Symptom:

 r.surf.idw runs for the whole coverage. No error message displayed. When
 finished, the target raster map is the very same as the input was.

 Command run:
 ''r.surf.idw --overwrite input=debugfrom at lidar output=debugto npoints=7
 ''
 Purpose: generate a continuous surface from a very sparse set of points on
 the map.
