Geosoft-Grid-to-Raster

Convert geosoft grid to an open format for useability

Data

• Gravity grid from Natural Resources Canada
  • http://gdr.agg.nrcan.gc.ca/gdrdap/dap/search-eng.php

Tools

• Mira Geoscience Geoscience Analyst
  • https://mirageoscience.com/mining-industry-software/geoscience-analyst/
• Geoh5py python package
  • https://geoh5py.readthedocs.io/en/stable/
• Rioxarray : goto tool for high level abstracted raster wrangling
  • https://corteva.github.io/rioxarray/stable/
• Geosoft
  • Viewer: https://www.seequent.com/products-solutions/geosoft-viewer/
    • For access to data conversion
  • Python package: https://pypi.org/project/geosoft/

Issues

Need Geosoft/login access to use the converter

• Free to sign up to get their viewer, but you can't export
• Geosoft has their own python package, so you could do it this way, however it is much more complicated
  • Use this if you use their gdbs or other stuff and have it already

Examples

Thomas Martin has a version of going to geoh5py via xarray and back here - https://github.com/MiraGeoscience/geoh5py/blob/6b3da659444fcd73323d8f36dba09312e841b7b1/examples/geoh5py_xarray_testing_and_back.ipynb

Summary

All of the above is a good example of why government data providers should also provide a version in an open format.

e.g. We don't want a future where we have to do this routinely to recover science: -

• This capability now exists in Harmonica - examples soon
