2024-06-17

Added

  • Add CITATION.cff file to provide a citation for the repository

Changed

  • Removed use of nan for fill_values to be more consistent with EMIT datasets. This means that users will have to manually assign them before plotting.
  • Updated notebooks to include the new fill_value behavior, and assign them to np.nan for visualizations
  • Replaced raw_spatial_crop with spatial_subset function to subset EMIT data spatially before applying orthorectification
  • Fixed typos in Earthdata Search Guide

2024-03-22

Added

  • geojson with plume bounding box for Visualizing Methane Plume Timeseries notebook

Changed

  • Updates to instructions in Visualizing Methane Plume Timeseries notebook
  • Remove horizontal lines from notebooks for web-book creation

2024-03-13

Added

  • Added new Visualizing Methane Plume Timeseries notebook
  • Added new Generating Methane Spectral Fingerprint notebook
  • Added new tutorial_utils.py module which has functions specific to the new CH4 notebooks

Changed

  • Updated setup_instructions.md to provide more up to date Python setup instructions
  • Updated README.md to include new notebooks
  • Added some functions to emit_tools.py to support the new methane tutorial notebooks
  • Minor updates to How to Extract Area and How to Extract Points notebooks to improve visualizations

2023-12-01

Changed

  • Applied automatic formatting to emit_tools.py
  • Fixed GLT index adjustment in raw_spatial_crop function
  • Reimplemented PointerXY stream so interactive plot from Exploring EMIT L2A Reflectance shows spectra at current cursor location

2023-11-27

Changed

  • Updated emit_tools.py to fix an issue with raw_spatial_crop
  • Updated some plotting visuals within notebooks
  • Improved interactive plots in Exploring_EMIT_L2A_Reflectance
  • Renamed CONTRIBUTE.md to CONTRIBUTING.md

2023-10-23

Changed

Changed

  • Default behavior of emit_xarray function from emit_tools.py no longer orthorectifies, must add parameter ortho=True
  • Removed 'bands' dimension in favor of 'wavelengths' for 'radiance' and 'reflectance' when using emit_xarray function from emit_tools.py
  • Updated write_envi function from emit_tools.py, it should work for L1A,L1B, and L2A products.
  • various other minor changes to emit_tools.py
  • Updated notebooks to support changes made to emit_tools.py
  • Improved RGB Image creation and brightness adjustment in Exploring_EMIT_L2A_Reflectance Tutorial
  • Each notebook now uses the earthaccess python library to handle NASA Earthdata Login and downloads of needed files
