webgeocalc 0.1

Python package for NAIF WebGeoCalc API

In december 2018, JPL/NAIF announced an experimental API RESTful interface for their new WebGeocalc server (which make online SPICE calculations). Documentation and JavaScript examples are already available.

This package is an early attempt to provide a Python interface to make SPICE calculation through this API.

Install

With pip:

$ pip install webgeocalc

With the source files:

$ git clone https://github.com/seignovert/python-webgeocalc.git webgeocalc
$ cd webgeocalc ; python setup.py install

Usage

>>> from webgeocalc import API

>>> API.url
'https://wgc2.jpl.nasa.gov:8443/webgeocalc/api'

>>> kernels = API.kernel_sets() # /kernel-sets
[
    <KernelSetDetails> Solar System Kernels (id: 1),
    <KernelSetDetails> Latest Leapseconds Kernel (id: 2),
    ...
    <KernelSetDetails> SPICE Class -- Binary PCK Lesson Kernels (Earth) (id: 39)
]

>>> kernel = kernels[0]
>>> int(kernel) # kernelSetId
1

>>> str(kernel) # Caption
'Solar System Kernels'

>>> kernel.description
'Generic kernels for planets, satellites, and some asteroids covering from 1950-01-01 to 2050-01-01.'

>>> kernel.keys()
dict_keys(['caption', 'sclkId', 'description', 'kernelSetId', 'missionId'])

>>> kernel.values()
dict_values(['Solar System Kernels', '0', 'Generic kernels for planets, satellites, and some asteroids covering from 1950-01-01 to 2050-01-01.', '1', 'gen'])
