gplately.PlotTopologies

class gplately.PlotTopologies(plate_reconstruction, coastlines=None, continents=None, COBs=None, time: float = 140.0, anchor_plate_id=None, plot_engine: ~gplately.mapping.plot_engine.PlotEngine = <gplately.mapping.cartopy_plot.CartopyPlotEngine object>)[source]

Bases: object

Read, reconstruct and plot topology features at specific reconstruction times.

The PlotTopologies class:

  • Read features held in GPlates GPML (GPlates Markup Language) files and ESRI shapefiles.

  • Reconstruct the locations of these features as they migrate through geological time.

  • Turn these reconstructed features into Shapely geometries for plotting.

To create the PlotTopologies object, supply:

and optionally,

  • a coastline_filename

  • a continent_filename

  • a COB_filename

  • a reconstruction time

  • an anchor_plate_id

For example:

 1# create a PlotTopologies object
 2gplot = gplately.plot.PlotTopologies(
 3    plate_reconstruction,
 4    coastline_filename=None,
 5    continent_filename=None,
 6    COB_filename=None,
 7    time=100,
 8    anchor_plate_id=None,
 9)
10
11# Setting a new reconstruction time
12gplot.time = 20  # Ma

The coastline_filename, continent_filename and COB_filename can be paths (str) to GPML and/or shapefiles, as well as instances of pygplates.FeatureCollection.

Some features for plotting (like plate boundaries) are taken from the PlateReconstruction.topology_features. They have already been reconstructed to the given time. Simply provide a new reconstruction time by changing the time attribute, e.g.

1gplot.time = 20 # Ma

which will automatically reconstruct all topologies to the specified time. You MUST set gplot.time before plotting anything.

A variety of geological features can be plotted on maps, including:

  • subduction boundaries & subduction polarity teeth

  • mid-ocean ridge boundaries

  • transform boundaries

  • miscellaneous boundaries

  • coastline polylines

  • continental polygons and

  • continent-ocean boundary polylines

  • topological plate velocity vector fields

  • netCDF4 MaskedArray or ndarray raster data:
    • seafloor age grids

    • paleo-age grids

    • global relief (topography and bathymetry)

  • assorted reconstructable feature data, for example:
    • seafloor fabric

    • large igneous provinces

    • volcanic provinces

plot_plate_id(*args, **kwargs)[source]

Deprecated! DO NOT USE!

The function name plot_plate_id() is bad and should be changed. The new name is plot_plate_polygon_by_id(). For backward compatibility, we allow users to use the old name in their legcy code for now. No new code should call this function.

plot_plate_motion_vectors(ax, spacingX=10, spacingY=10, normalise=False, **kwargs)[source]

Calculate plate motion velocity vector fields at a particular geological time and plot them on a map.

Note

The plot_plate_motion_vectors() generates a MeshNode domain of point features using given spacings in the X and Y directions (spacingX and spacingY). Each point in the domain is assigned a plate ID, and these IDs are used to obtain equivalent stage rotations of identified tectonic plates over a 5 Ma time interval. Each point and its stage rotation are used to calculate plate velocities at a particular geological time. Velocities for each domain point are represented in the north-east-down coordinate system and plotted on a GeoAxes.

Vector fields can be optionally normalised by setting normalise to True. This makes vector arrow lengths uniform.

Parameters:
  • ax – Cartopy ax.

  • spacingX (int, default=10) – The spacing in the X direction used to make the velocity domain point feature mesh.

  • spacingY (int, default=10) – The spacing in the Y direction used to make the velocity domain point feature mesh.

  • normalise (bool, default=False) – Choose whether to normalise the velocity magnitudes so that vector lengths are all equal.

  • **kwargs – Keyword arguments for plotting the velocity vector field. See Matplotlib quiver keyword arguments here.

plot_plate_polygon_by_id(ax, plate_id, color='black', **kwargs)[source]

Plot a plate polygon with the given``plate_id`` on a map.

Parameters:
  • ax – Cartopy ax or pygmt figure object.

  • plate_id (int) – A plate ID that identifies the continental polygon to plot. See the Global EarthByte plate IDs list for a full list of plate IDs.

  • **kwargs – Keyword arguments for plotting.

plot_pole(ax, lon, lat, a95, **kwargs)[source]

Parameters:
  • ax – Cartopy ax.

Parameters:
  • ax – Cartopy ax or pygmt figure object.

  • spacing (float, default=0.07) – The tessellation threshold (in radians). Parametrises subduction tooth density. Triangles are generated only along line segments with distances that exceed the given threshold spacing.

  • aspect (float, default=None) – Aspect ratio of teeth triangles. If kept at None, then aspect = 2/3*size.

  • color (str, default='black') – The colour of the teeth. By default, it is set to black.

  • **kwargs – Keyword arguments for plotting subduction teeth. See Matplotlib keyword arguments here.
