pygmt.Figure.basemap

Figure.basemap(**kwargs)

Produce a basemap for the figure.

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 options frame, map_scale, rose or compass must be specified.

Full option list at https://docs.generic-mapping-tools.org/latest/basemap.html

Aliases:

  • B = frame

  • J = projection

  • L = map_scale

  • R = region

  • Td = rose

  • Tm = compass

  • U = timestamp

  • t = transparency

Parameters

  • projection (str) – Required if this is the first plot command. Select map projection.

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

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

  • map_scale (str) – '[g|j|J|n|x]refpoint' 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.

  • transparency (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).
