[GRASS-user] t.rast.mapcalc for interpolate nulls

[Diana Brito]

Hi list!

I have a problem with de mannagment of nulls values, i have a termporal
serie of lst daily (MODIS), i want to interpolate each image in order to
estimate de values of the nulls cells, I want to get the value of the null
cell, by averaging the same position in xy but the *previous time and the
next*, i don´t have any idea how to indicate the position of the null cell
neither the way to calculate the average.

Is it possible to do this with t.rast.mapcalc? how? another function?

I,m using grass71

thanks for your help in adnvance
