Update several notebooks to use cleaner `odc-geo` code

robbibt commented 6 months ago

Proposed changes

The Open Data Cube Geo / odc-geo package now includes functionality to make it easy to perform spatial processing tasks using its built-in .odc. methods that are automatically added to xarray data.

For example, we can now mask an xarray dataset by a polygon using:

import odc.geo.xr
ds.odc.mask(poly)

Or reprojecting a dataset:

ds.odc.reproject(how="EPSG:3577")

This PR updates several notebooks to take advantage of this new functionality and simplify our code.

It also adds a new load_reproject function which uses odc.geo and rasterio to load and reproject external rasters to match data loaded from DEA.

Closes issues (optional)

Closes Issue #000

Checklist

(Replace [ ] with [x] to check off)

[x] Notebook created using the DEA-notebooks template
[x] Remove any unused Python packages from Load packages
[x] Remove any unused/empty code cells
[x] Remove any guidance cells (e.g. General advice)
[x] Ensure that all code cells follow the PEP8 standard for code. The jupyterlab_code_formatter tool can be used to format code cells to a consistent style: select each code cell, then click Edit and then one of the Apply X Formatter options (YAPF or Black are recommended).
[x] Include relevant tags in the final notebook cell (refer to the DEA Tags Index, and re-use tags if possible)
[x] Clear all outputs, run notebook from start to finish, and save the notebook in the state where all cells have been sequentially evaluated
[ ] Test notebook on both the NCI and DEA Sandbox (flag if not working as part of PR and ask for help to solve if needed)
[ ] If applicable, update the Notebook currently compatible with the NCI|DEA Sandbox environment only line below the notebook title to reflect the environments the notebook is compatible with
[x] Check for any spelling mistakes using the DEA Sandbox's built-in spellchecker (double click on markdown cells then right-click on pink highlighted words). For example:

sandbox_spellchecker

Hey @BexDunn, I fixed up the comment - but when I re-ran the notebook, the runtime warning disappeared. I've had that happen before - it's a confusing! Can keep an eye out for it if it re-appears
