# Planetary Data System
The PDS standards, in particular PDS3, are/is explained in the ESA link
* https://www.cosmos.esa.int/web/psa/pds-standards
as well as NASA's
* https://pds.jpl.nasa.gov/
, where they (the americans) go in further details explaining their PDS
(thematic) nodes. As for the _data_ standards, in NASA's PDS website,
in particular PDS3, the following link may be of better help:
* https://pds.jpl.nasa.gov/datastandards/pds3/standards/
; The content of it is in the attached document:
* [PDS3_StdRef_20090227_v3.8.pdf]

# Tools for ESA/NASA data users
## MRO / CRISM

## ESA Planetary Science Archive (PSA)
We start at the [PDS Geosciences Node] page for [MRO CRISM] data access.
PSA introduction page, https://www.cosmos.esa.int/web/psa/psa-introduction,
provides links to PDS standards, data access, resources, etc:
* PDS3: https://www.cosmos.esa.int/web/psa/pds-standards,
* PDS4: https://www.cosmos.esa.int/web/psa/pds4-standards,
* data access: https://www.cosmos.esa.int/web/psa/psa-interfaces,
* resources *: https://www.cosmos.esa.int/web/psa/resources.
First thing to cover is the [Data Product Software Interface Specification].
And the list of data in their FTP:

## Other tools
## ESA/PSA
ESA missions: https://www.cosmos.esa.int/web/psa/missions
Considered core sofware for working with PDS4 data are available at
https://pds.jpl.nasa.gov/tools/about/.
The address https://www.cosmos.esa.int/web/psa/tools provide a concise list of
tools meant to help users put their hands over the data:
And at https://pds.jpl.nasa.gov/tools/tool-registry/ there is a
search tools for tools working with data following PDS standards
From the list of resources we pre-select some surely useful
documents and links about tools we might as well use:
* VICAR: http://www-mipl.jpl.nasa.gov/external/vicar.html
* File format: https://www-mipl.jpl.nasa.gov/external/VICAR_file_fmt.pdf
* Start guide: https://www-mipl.jpl.nasa.gov/vicar_os/v2.0/vicar-docs/VICAR_guide_2.0.pdf

Quote:
> PDS3 datasets can incorporate a VICAR header.
> By default, GDAL will use the PDS driver in that situation.
> Starting with GDAL 3.1, if the GDAL_TRY_PDS3_WITH_VICAR configuration option is set to YES,
> the dataset will be opened by the VICAR driver.
### INSTRUMENT-SPECIFIC SOFTWARE
Instrument-specific software is not included in this list, but can be found in
the Mission or Instrument pages.
Software tools, libraries, or utility programs to access or process data products,
if provided by the instrument team, are available in the SOFTWARE, DOCUMENT or
EXTRAS directory of the corresponding dataset, along with instructions.
### ANCILLARY SOFTWARE TOOLS (SPICE)
A software library and other useful utilities to read SPICE kernels and to
compute derived observation geometry, such as altitude, latitude/longitude,
and lighting angles, can be found in the NAIF SPICE Toolkit page.
This software is offered in FORTRAN, C, IDL and MATLAB.

ODE has a simple, plain website at https://ode.rsl.wustl.edu/mars/indexDatasets.aspx
that is very well structure. It can be seen at [this link], where we query for
the `browse` directory of observation `0010` of `MEX/HRSC` `DTM` data products
