Starship Asterisk*

Where can I find some explanations about naming conventions for hirise images?
What does PSP_3647_1745 stand for?
How can I find the "PSP image" for a known latitude/longuitude position?

PSP_003647_1745 is apparently an observation ID. you can look through label to find correlations, or simply ask here.

Looking at their viewer, though, it seems that only few spots were covered, so I don't think you can simply poke at random latitude/longuitude like here.

I found official documentation about naming convention:

Here it is an excerpt:
ppp_oooooo_tttt_ffff_c.IMG

ppp = Mission Phase:
INT = Integration and Testing
CAL = Calibration Observations
ATL = ATLO Observations
KSC = Kennedy Space Center Observations
SVT = Sequence Verification Test
LAU = Launch
CRU = Cruise Observations
APR = Mars Approach Observations
AEB = Aerobraking Phase
TRA = Transition Phase
PSP = Primary Science Orbit (nov 2006-nov 2008)
REL = Relay phase
E01 = 1st Extended Mission Phase if needed
Exx = Additional extended Missions if needed


oooooo = MRO orbit number

tttt = Target code.

The target code refers to the latitudinal
position of the center of the planned
observation relative to the start of orbit.
The start of orbit is located at the equator
on the descending side (night side) of the
orbit. A target code of 0000 refers to the
start of orbit. The target code increases in
value along the orbit track ranging from 0000
to 3595. This convention allows the file name
ordering to be time sequential. The first
three digits refers to the number of whole
degrees from the start of orbit, the fourth
digit refers to the fractional degrees rounded
to the nearest 0.5 degrees. Values greater
that 3595 identify observations as off-Mars or
special observations.
Examples of target code:
0000 – planned observation at the equator on
descending side of orbit.
0900 – planned observation at the south pole.
1800 – planned observation at the equator on
the ascending side (day side) of the orbit.
2700 – planned observation at the north pole.
Off-Mars and Special Observations Values:
4000 – Star Observation
4001 – Phobos Observation
4002 – Deimos Observation
4003 – Special Calibration Observation

ffff Filter/CCD designation:
RED0-RED9 - Red filter CCDs
IR10-IR11 – Near-Infrared filter CCDs
BG12-BG13 – Blue-Green filter CCDs

C Channel number of CCD (0 or 1)

so... seing how far you have advanced into this, is there complete list of ppp_oooooo_tttt_ffff_c.IMG images, where one can see if some specific combination exists, online?

EDIT: I poked their online viewer and found this xml. It is only ~130k, so probably incomplete.

I found this site:
http://hirise-pds.lpl.arizona.edu/PDS/

But I don't know if it does contain ALL images.

This is a nice search engine (just specify MRO as "mission"):

A link to all repositories for MRO images:

Notes from http://hirise-pds.lpl.arizona.edu/PDS/AAREADME.TXT:

Experimental Data Record (EDR) Products are the permanent record of the raw images obtained by HiRISE. The EDRs have the properties of
unprocessed and unrectified imaging maintaining the original spacecraft
viewing orientation and optical distortion properties.

RDR products are radiometrically-corrected images resampled to a standard map projection. They are formatted and organized according to the standards of the PDS.
