pygmt.Figure.basemap

Figure.basemap(**kwargs)

Plot base maps and frames for the figure.

Creates a basic or fancy basemap with axes, fill, and titles. Several map projections are available, and the user may specify separate tick-mark intervals for boundary annotation, ticking, and [optionally] gridlines. A simple map scale or directional rose may also be plotted.

At least one of the parameters frame, map_scale, rose or compass must be specified.

Aliases:

  • B = frame

  • J = projection

  • JZ = zsize

  • Jz = zscale

  • L = map_scale

  • R = region

  • Td = rose

  • Tm = compass

  • U = timestamp

  • V = verbose

  • X = xshift

  • Y = yshift

  • c = panel

  • f = coltypes

  • p = perspective

  • t = transparency

Parameters

  • projection (str) – Required if this is the first plot command. projcode[projparams/]width. Select map projection.

  • zscale/zsize (float or str) – Set z-axis scaling or z-axis size.

  • region (str or list) – Required if this is the first plot command. xmin/xmax/ymin/ymax[+r][+uunit]. Specify the region of interest.

  • frame (bool or str or list) – Set map boundary frame and axes attributes.

  • map_scale (str) – [g|j|J|n|x]refpoint+wlength. Draws a simple map scale centered on the reference point specified.

  • rose (str) – Draws a map directional rose on the map at the location defined by the reference and anchor points.

  • compass (str) – Draws a map magnetic rose on the map at the location defined by the reference and anchor points

  • timestamp (bool or str) – Draw GMT time stamp logo on plot.

  • verbose (bool or str) –

    Select verbosity level [Default is w], which modulates the messages written to stderr. Choose among 7 levels of verbosity:

    • q - Quiet, not even fatal error messages are produced

    • e - Error messages only

    • w - Warnings [Default]

    • t - Timings (report runtimes for time-intensive algorthms);

    • i - Informational messages (same as verbose=True)

    • c - Compatibility warnings

    • d - Debugging messages

  • xshift (str) – [a|c|f|r][xshift]. Shift plot origin in x-direction.

  • yshift (str) – [a|c|f|r][yshift]. Shift plot origin in y-direction. Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#xy-full.

  • panel (bool or int or list) – [row,col|index]. Selects a specific subplot panel. Only allowed when in subplot mode. Use panel=True to advance to the next panel in the selected order. Instead of row,col you may also give a scalar value index which depends on the order you set via autolabel when the subplot was defined. Note: row, col, and index all start at 0.

  • coltypes (str) – [i|o]colinfo. Specify data types of input and/or output columns (time or geographical data). Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#f-full.

  • perspective (list or str) – [x|y|z]azim[/elev[/zlevel]][+wlon0/lat0[/z0]][+vx0/y0]. Select perspective view and set the azimuth and elevation angle of the viewpoint. Default is [180, 90]. Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#perspective-full.

  • transparency (int or float) – Set transparency level, in [0-100] percent range. Default is 0, i.e., opaque. Only visible when PDF or raster format output is selected. Only the PNG format selection adds a transparency layer in the image (for further processing).
