pytsg

Rationale

The spectral geologist (TSG) is an industry standard software for hyperspectral data analysis https://research.csiro.au/thespectralgeologist/

pytsg is an open source one function utility that imports the spectral geologist file package into a simple object.

Installation

Installation is via pip pip install pytsg

Usage

If using the top level importer the data is assumed to follow this structure ``` \HOLENAME \HOLEMAMEtsg.bip \HOLENAMEtsg.tsg \HOLENAMEtsgtir.bip \HOLENAMEtsgtir.tsg \HOLENAMEtsghires.dat \HOLENAMEtsgcras.bip

```

```python from matplotlib import pyplot as plt from pytsg import parse_tsg

data = parsetsg.readpackage('example_data/ETG0187')

plt.plot(data.nir.wavelength, data.nir.spectra[0, 0:10, :].T) plt.plot(data.tir.wavelength, data.tir.spectra[0, 0:10, :].T) plt.xlabel('Wavelength nm') plt.ylabel('Reflectance') plt.title('pytsg reads tsg files') plt.show()

```

If you would prefer to have full control over importing individual files the following syntax is what you need

```python

bip files

nir = parsetsg.readtsgbippair('ETG0187tsg.tsg','ETG0187tsg.bip','nir') tir = parsetsg.readtsgbippair('ETG0187tsgtir.tsg','ETG0187tsgtir.bip','tir')

cras file

cras = parsetsg.readcras('ETG0187tsgcras.bip')

hires dat file

lidar = parsetsg.readlidar('ETG0187tsghires.dat')

``` For convienience

Thanks

Thanks to CSIRO and in particular Andrew Rodger for his assistance in decoding the file structures.
