### PDS
Planetary Data System (PDS) is an assemble of (i) data archive (structure) standards and (ii) data access thematic nodes. The former, standards, state the rules through each missions and data providers should lay down datasets content. Current version of PDS standard is `4` -- PDS4 --, though most of the imagery archives of our interest follow the version `3` (PDS3).
The thematic data access nodes split planetary data according to their scientific subject, for instance, we -- as geoscientists -- relate to the [PDS Geoscience Node](https://pds-geosciences.wustl.edu/) (PDS-Geo).
To know more about PDS archive standards, see:
* PDS3: https://pds.jpl.nasa.gov/datastandards/pds3/standards/
* PDS4: https://pds-geosciences.wustl.edu/dataserv/pds4.html
And and _index_ page of PDS-Geo data services is provided at:

#### Software support
* Python interface for PDS headers: the library from `pds3` ([github/pds3, Michael Kelley](http://www.github.com/mkelley/pds3)) reads PDS3 products into lists and tuples and dictionaries in Python.
* GDAL interface for PDS files: https://gdal.org/drivers/raster/pds.html

### MRO HiRISE
The High Resolution Imaging Experiment (HiRISE) provides images with resolution down to 30 centimetres per pixel in visible and near-infrared wavebands.
HiRISE Reduced Data Records (RDR) products are radiometrically corrected and projected to a standard map projections. Different from the other PDS archive, RDR images are in JPEG2000 format. Typically, each observation provides two RDR products, a single-color product from the _red_ filter, and a three-colour image using _blue_ and _near-infrared_ detectors -- if all CCDs were operating.
* Dataset ID: HiRISE
* Dataset URL: `https://hirise-pds.lpl.arizona.edu/PDS/`
* Data format: `JPEG2000` + `PDS LABEL`
* Data volume: 10TB
#### Data archive summary
The `RDR/` directory immediately under the volume's root directory. These directories contain a cascading set of subdirectories organizing the products by mission phase (level 1), orbit range or time period range (level 2), and observation identification (level 3).
HiRISE archive has an `EXTRAS/` directory tree with JPEG2000 fullresolution products and browse images of the EDR, RDR, and DTM standard products and 3-D anaglyph products in the JPEG2000 and png formats.
The standard set of products include one DTM plus two orthoimages for each source image used to create the DTM, for a total of five standard products for each DTM. The HiRISE RDR products have detached PDS labels.
#### File naming
HiRISE Observation IDs are 15 characters in length in three fields: a mission phase Identification, orbit number, and target code.
> * mission phase:
> * AEB - Aerobraking Phase
> * TRA - Transition Orbit Phase
> * PSP - Primary Science Phase
> * REL - Relay Phase (if needed)
> * E01 - 1st Extended Mission Phase (if needed)
> * Exx - Any possible extended mission phase (if needed)
> * orbit number is a six-digit, zero-padded number
> * target code is a four-digit zero-padded chronologically ordered number within an orbit
Example: the Observation ID `PSP_002170_0990`, is a Primary Science Phase observation, acquired on orbit 2170. The observation was acquired near the South Pole.
The RDR product file names are constructed by appending `_RED` or `_COLOR` to the Observation ID. The `_RED` designation is a single-band image compiled from the Red-filter images operating during the observation. The `_COLOR` designation is a three-color image complied from the overlapping blue-green, red, and near-infrared detectors.
#### Coordinates reference system
The coordinate system used is planetocentric latitude and east positive longitude direction. The planetocentric latitude is the angle from the equator to a point on the surface of an oblate planet. The longitude increases from west to east (left to right).
Two map projections are used in the HiRISE RDR products: Equirectangular and Polar Stereographic.

### MRO CTX
TBD
The Context Camera (CTX), on board of the Mars Reconnaissance Orbiter, aquire images with a spatial resolution of 6 meters per pixel, over an aperture of 30 kilometers wide. It was designed to provide context to other, high resolution observations from HiRISE and CRISM experiments.
### MRO HiRISE
CTX provides Experiment Derived Records (EDR) data, simgle images in raw format.
TBD
* Dataset ID: `MRO-M-CTX-2-EDR-L0-V1.0`
* Archive URL: `https://pds-imaging.jpl.nasa.gov/data/mro/ctx/`
* Data format: `PDS IMAGE` + `PDS LABEL`
