Load .csv or .dat file in PyGMT

[zulfakriza]

Description of the problem

Hi, I am a new user on PyGMT, before I used GMT 5 to create some map and plotting the EQ data. But in PyGMT I had a bit issue when trying to load data (.csv or .dat) in my map.

Is there any clue how to load .csv or .dat data format in PyGMT?

Thank you

Hi @zulfakriza,

For .csv files, you can follow the answer outlined at https://forum.generic-mapping-tools.org/t/how-to-load-data-into-pygmt/392, basically by using pandas. I actually made an example using earthquake data before from GNS, New Zealand at https://nbviewer.jupyter.org/github/GenericMappingTools/foss4g2019oceania/blob/master/2_pydata_and_pygmt.ipynb.

As for .dat files, you might need to upload an example as it's quite a generic format. Is it a binary format, ASCII text format, or something else?

Hi @weiji14

Many thanks for your response, then for the .dat file, I mean ASCII text format

If it's just text, then pandas.read_csv should work on that .dat file too. There's options to skip header lines, set column names, etc.

That said, some of the Data Processing functions allow you to pass the filename into PyGMT directly. So it depends on what you want to do :smile:
