Module Natural Neighbour
Natural Neighbour method for grid interpolation from irregular distributed points. This tool makes use of the 'nn - Natural Neighbours interpolation library' created and maintained by Pavel Sakov, CSIRO Marine Research. Find more information about this library at:

Output | Target Grid | Grid (output) | TARGET_OUT_GRID | - | - |
Options | Attribute | Table field | FIELD | - | - |
Target Grid System | Choice | TARGET_DEFINITION | - | Available Choices: [0] user defined [1] grid or grid system Default: 0 | |
Left | Floating point | TARGET_USER_XMIN | - | Default: 0.000000 | |
Right | Floating point | TARGET_USER_XMAX | - | Default: 100.000000 | |
Bottom | Floating point | TARGET_USER_YMIN | - | Default: 0.000000 | |
Top | Floating point | TARGET_USER_YMAX | - | Default: 100.000000 | |

Minimum Weight | Floating point | WEIGHT | restricts extrapolation by assigning minimal allowed weight for a vertex (normally "-1" or so; lower values correspond to lower reliability; "0" means no extrapolation) | Maximum: 0.000000 Default: 0.000000 | |
(*) optional |
