[GPlates-discuss] Conversion of text data for plotting lines and points

[Genti Toyokuni]

Dear John and Christian,

Thank you very much for letting me know several ways to solve this problem.
First I tried to run "convert_xy_to_gplates.py". However I received
several syntax errors, which may be due to difference in version of
Python in my environment.
(I am using Python 2.5.4 in Vine Linux. I should run your programs in
Python 3.x)

Second I tried to open my data files directly in GPlates but it also
showed many errors.

The attached files are as follows:
coast-eclip.dat: Coastline data (lon, lat) in the ecliptic coordinates
which was chosen for the central Greenland to be at (lon=90deg,
lat=0deg).
volcano_lonlat_eclip.dat: Location of volcanoes (lon, lat) in the same
coordinates.

If you have time, would you please confirm that you can convert these
files into "gpmlz" format?

Best wishes,

Genti Toyokuni

> It works on its own, so if you want you can just copy it from there instead of installing the entire package (eg, hit 'raw' and copy'n'paste - sorry I'm not very experienced with Git).

> To see the options run:
>
>     python convert_xy_to_gplates.py --help
>
> ...and you'll also see some examples of what the script does.

> For your second point, you can use the "-s" option (eg, "-s depth") and then the third column of your XY file (depth) will then show up in GPlates (once you've loaded the generated GPML file) as a separate colour on each point (that you can then configure with colour palettes).

>
> Before running the script, you'll need to install pyGPlates (and it currently only works with Python 2.7, though next year will also support Python 3):

> Dear Sirs;
>
> Thank you very much for providing us a great software!
> I want to ask you the following two points:
>
> (1) How can I convert a simple text list of longitudes and latitudes including a ">" sign as a line separator, which is commonly used in Generic Mapping Tools, into "gpmlz" format? I want to plot several lines specified by the list on the Earth's surface.
>
> (2) How can I convert a simple text list of longitudes, latitudes, and depths showing locations of volcanoes, hotspots, and hypocenters into a file format which can be opend by GPlates?
>
> I am sorry for my very basic questions.
