NEANIAS Planetary Tools

This Python library provides the data/metadata processing tools running in NEANIAS/MEEO backend planetary data store. We are handling data provided by NASA/USGS Planetary Data System (PDS).

Main tools:

• search: query PDS' Orbital Data Explorer (ODE) using a bounding-box or a Product-ID.
• download: download data and metadata files from search
• reduce: process data from ODE to our data storing level (science-ready, GeoTIFF)
• mosaic: provide different functions for spatial mosaic'ing (GDAL, Rasterio, xarray)

General tools:

• isis: ISIS utilities, primarily used during reduce PDS files
• utils: misc utilities (data I/O, formatting, temp files support, etc.)
• pipelines: ADAM-DPS specific interface

Install

Installing the latest stable version on Pypi:

$ pip install npt

Installing a specific version from Github:

bash
$ pip install https://github.com/chbrandt/npt/archive/refs/tags/v0.7.2.zip

Or, for developers, directly from a local copy of this repository:

$ git clone https://github.com/chbrandt/npt.git
$ cd npt
$ pip install -e .

Python

• What's for datasets?:

> import npt
> help(npt.datasets)

Help on package npt.datasets in npt:

NAME
    npt.datasets - Datasets dynamic import

PACKAGE CONTENTS


FUNCTIONS
    descriptors(dataset_id)
        Return descriptors set for given 'dataset'

    filters(dataset_id)
        Return filters set for given 'dataset'

    list()
        Return (sorted) list of available datasets

FILE
    /home/chbrandt/lib/npt/npt/datasets/__init__.py

>

• List the available datasets:

> npt.datasets.list()

['mars/mex/hrsc/rdrv3',
 'mars/mex/hrsc/refdr3',
 'mars/mro/ctx/edr',
 'mars/mro/hirise/rdrv11']
>

• How to search for data products for a given dataset:

> import npt
> help(npt.search)

Help on package npt.search in npt:

NAME
    npt.search - Query USGS/ODE API for image data products

PACKAGE CONTENTS
    _ode

FUNCTIONS
    ode(dataset: str, bbox: dict, match: str = 'intersect', bbox_ref: str = 'C0')
        Return GeoDataFrame with found data products as features

        Input:
        - dataset: name of the dataset (see `npt.datasets`)
        - bbox: bounding-box to query overlapping products.
                Dictionary keys: minlat, maxlat, westlon, eastlon;
                Latitude/longitude values range: (-90:90, -180:180)
        - match: how to consider overlapping matching footprints.
                 Options are: 'intersect', 'contain'
        - bbox_ref: if 'C0' (default), 'bbox' longitudes are centered at 0 (-180:180),
                    if 'C180', 'bbox' longitudes are centered at 180 (0:360).

• Search HiRISE, for example:

> # Define the dataset and region to query for images
> dataset = 'mars/mro/hirise/rdrv11'
> bbox = dict(
    westlon = -1,
    eastlon = 1,
    minlat = -1,
    maxlat = 1
  )
> # Search ODE
> gdf = npt.search.ode(dataset, bbox)
INFO:_ode.parse(): 11 products found
>
> # Print search results
> gdf
