specarray 0.1.1rc119.post1

Working with hyperspectral data

SPECARRAY

To read, analyze and plot hyperspectral data from Specim devices. Currently only tested with FX10 data.

Core features

• read Specim instrument data
• support for large files thanks to dask
• using xarray for data handling and data analysis
• computation of spectral albedo and braodband albedo if white and dark reference is available

Installation

pip install specarray

Usage

from specarray import SpecArray
from pathlib import Path
import matplotlib.pyplot as plt

data_dir = Path("data/white_weathering_crust_2_2023-07-15_15-25-24/")

white_weathering_crust = SpecArray.from_folder(data_dir)

white_weathering_crust.capture

white_weathering_crust.spectral_albedo.sel(sample=0, point=0).plot.line()
plt.ylim(0, 1)

The resulting imgage should look like this:
