TRANSFORM 2020 has ended
Welcome to the first global, virtual TRANSFORM! The Software Underground is excited to bring you lots of interesting and useful sessions on the digital subsurface. The schedule is still taking shape, but this event is a bit different from most conferences: the sessions are all fully participatory and interactive. Get ready for a conversation!

If you are viewing the schedule on the web, you can select the timezone you wish to see in the menu on the right. In the mobile app, times are shown in UTC.

Tutorial: From scattered data to gridded products using Verde

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

This tutorial will be a hands-on tour of Verde, a Python package for processing and gridding geophysical/geospatial data with a twist of machine learning.
BEFORE THE TUTORIAL: Please go to github.com/fatiando/transform2020 and follow the setup instructions. There is also information on where to ask questions and what is going to happen in the tutorial.

We'll start with a real dataset and work our way towards producing one or more gridded products. The way there will take us through:

  • Loading some data
  • Generating and handling coordinates and projections (using pyproj)
  • Splitting training and testing data for validation
  • Data decimation with blocked means/medians to avoid aliasing
  • 2D trend estimation
  • Gridding with bi-harmonic splines
  • Combining everything into a data processing pipeline
  • Cross-validation of data distrubuted spatially on the Earth (including parallel execution)

UPDATE: Given the size of the tutorial, this will mainly be some live coding to showcase what Verde can do with participants following along. There will be some short exercises that can be done individually after the tutorial is finished. We will finish a bit earlier than the scheduled time to leave room for more questions/chat at the end.
