Interpretive gridding by anisotropic kriging
An algorithm of this type produces a much more reasonable map of aeromagnetic data from the Cobb Offset zone of the Juan de Fuca Ridge than either minimum curvature gridding or isotropic kriging. Most interpolation algorithms perform poorly on data sampled along profiles crossing features whose length scales are small along the profiles but ...

Gridding, objective mapping, and kriging (Chapter 7)
The grid dimensions could be latitude–longitude, like the familiar topographic map, or involve other dimensions such as time, depth, or even property values (e.g. temperature, oxygen, chlorophyll). Mathematical gridding is common in visualization because computers can only draw contour lines if they know where to draw them.

A Basic Understanding of Surfer Gridding: Data Metrics
A Basic Understanding of Surfer Gridding: Data Metrics Surfer offers many different grid based maps, such as 2D contour maps and 3D surface maps. To create a grid based map, you must have a grid file. To create a grid file, Surfer takes randomly spaced XYZ data and uses it to create a regularly spaced grid file, composed of grid nodes.

Gridding Data Methods
The process of gridding takes point (XYZ) data and interpolates the readings to determine the values at the nodes of a grid in between the data points. The resulting interpolated data set is known as a grid. The table below provides a summary of the different gridding methods you can use to grid your data as well as fundamental gridding concepts.

A New Dimension of Surfer: 3D Gridding Features
Now when presenting data to clients you can interactively display how a map changes with depth/elevation through a 3D grid. By creating a grid-based map from a 3D grid VTK or HDF file you can create a 2D slice of your data at any corresponding Z value. With just a simple click and drag of the Z value slice slider the map will update on the fly.

Comparison of some gridding methods
Gridding of irregularly spaced data is extremely common in geology and geophysics—consider scattered well data, depth picks on radiating or irregularly spaced seismic lines and, of course, land gravity surveys. Gridding is necessary and prevalent because contouring, processing, and even forward modeling and inversion require that data be regularly sampled. This paper …
