Session Three ? GMT 6.1.1 documentation - The Generic Mapping Tools
...GMT comes with several utilities that can create gridded data sets; we will discuss two such modules later this session. The data sets needed for this tutorial are obtained via the Internet as they are needed....

Grid file from a txt file - Q&A - GMT Community Forum
...The values in gravity.xyz looks gridded to me. Then you should get a gridfile that gmt can use. Next would be to plot it (and mask areas with no data). Tip: gmt info gravity.xyz to get the extent. Increment you have to eyeball the textfile. I dont know of a way to check this. This is my script but I am not able to proceed. may work. Good progress!...

(15) Gridding, contouring, and masking of unconstrained areas
...This example demonstrates some off the different ways one can use to grid data in GMT, and how to deal with unconstrained areas. We first convert a large remote ASCII file to binary with gmtconvert since the binary file will read and process much faster....

Gridding and Surface Fitting | GenericMappingTools/gmt | DeepWiki
...These tools transform irregularly spaced observations into continuous surfaces suitable for visualization and analysis. For basic grid operations like cutting and sampling, see Grid Operations. For specialized geophysical modeling, see Geophysical Modeling....

(16) Gridding of data, continued ? GMT 6.6.0 documentation
...(16) Gridding of data, continued contour (for contouring) and triangulate (for gridding) use the simplest method of interpolating data: a Delaunay triangulation (see Example (12) Optimal triangulation of data) which forms z (x, y) as a union of planar triangular facets....

Plot points from a .txt file on a pygmt map - GMT Community Forum
...I have a topographic map of North Irleand and I would like to plot seismic stations as points on it. I have a ?.txt? file with the name and coordinates (longitude and latitude) of the seismic stations I want to plot and they are divided by sep....

(14) Gridding of data and trend surfaces ? GMT 6.6.0 documentation
...This example shows how one goes from randomly spaced data points to an evenly sampled surface. We arrange for four panels using the subplot command. First we plot the distribution and values of our raw data set (same as in Example (12) Optimal triangulation of data)....
