Shapes grid¶

Description¶

Creates a new vector layer as a result of the union of a points layer with the interpolated value of one or more base background grid layer(s). This way, the new layer created will have a new column in the attribute table that reflects the interpolated value of the background grid.

Parameters¶

Points [vector: point]

Input layer.

Grids [multipleinput: rasters]

Background grid layer(s)

Interpolation [selection]

interpolation method to use.

Options:

• 0 — [0] Nearest Neighbor
• 1 — [1] Bilinear Interpolation
• 2 — [2] Inverse Distance Interpolation
• 3 — [3] Bicubic Spline Interpolation
• 4 — [4] B-Spline Interpolation

Default: 0

Outputs¶

Result [vector]

The resulting layer.

Console usage¶

processing.runalg('saga:addgridvaluestopoints', shapes, grids, interpol, result)
