Comparison with other plotting packages
Q - Is GMT.jl different from the other plotting packages in Julia?
A - Yes and No.
GMT.jl uses a
Plotslike syntax and is a general purpose plotting package but doesn't provide (yet) the more exotic plot types that can be found in
It is not interactive like GLMakie.
It works in a similar way of Luxor and CairoMakie in the sense that a vector graphics is generated and at the end rasterized for displaying. The plot quality should be similar to that of those packages (they use the Cairo library and GMT uses its own PostScript library). A prof of this quality is that GMT has been used for the last 30 years in publishing papers in the highest ranked journals.
GMT.jl builds on 30 years of experience in fine-tunning details for producing highest quality maps (BTW
Generic Mapping Tools) with lots of mapping projections and a deep knowledge that the Earth is round.
The figure dimensions in GMT are stated in physical units of cm (or inch), not pixels. The internal PS machinery uses integer numbers at an effective DPI of 1200. This allows to keep PostScript files reasonably small and at same time permits to create figures that can go as big as 11 x 11 meters.
GMT.jl is not a map/plotting package only. It has innumerous tools for grid and vector data processing. e.g. read virtually almost all formats (directly or via GDAL), grid interpolations, 1 and 2D filtering, coordinate conversions, direct access to many of GDAL, PROJ, GEOS functions, dedicated tools for seismology, geodesy, potential methods (gravity and geomagnetism), etc...
Thanks to Julia's FFI (Foreign Function Interface) GMT.jl can interface with the MB-system software from swath-bathymetry data processing.
