[STATSGRASS] R/grass, numerical instability/kriging

[Tomas Lanczos]

Hello,

finally I solved it - one of the points were duplicated another two points
were too close to each others, now it's perfect, thank You. However, is
there a common rule for e.g. selecting resolution for the given smallest
distance the measurments?

regards

Tomas
