I've got a point shapefile of river sonar data. It got only two fields:
depth. I want to interpolate
depth of selected 40 points (arranged by
id) value from 1.49 to 1. Any idea how can I do it with
QGIS Field Calculator?
For now I've got only one lame solution:
1.5 - @row_number/100
I'm sure that more elegant and mathematical approach exists.
