High Resolution Imaging Science Experiment (HiRISE) Stamp Layer

The HiRISE Stamp Layer will display stamps for all images acquired by the High Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter. While the search interface is similar to the THEMIS Stamp Layer, there are some differences that allow users to search for images based on the unique parameters associated with HiRISE images.

Open the HiRISE Stamp Layer

  1. Open the Stamp Layer: Chose "Add New Layer" -> "Imagery" -> Make sure that "Image Sets" is selected and click "HiRISE" OR Chose "Add New Layer" -> "Instrument" -> "HiRISE"

  1. Search Parameter Categories: The search parameters are divided into categories since there are so many of them. Clicking on the down arrow on the right side of the category name will reveal all the search parameters in that category. The categories are:
    • Basic Parameters
    • Advanced Parameters
    NOTE: A search can be performed with parameters set in multiple categories.
  1. Enter Search Parameters: It is not necessary to enter values for each parameter, but the more specific your search the faster it will be. The allowable values for each field are given in the quick reference table below followed by more detailed descriptions of each search parameter.
  1. Perform Image Search: Clicking OK will make the Stamp Layer perform the search and display the results. Depending on how specific the search parameters are, it may take the Stamp Layer a few minutes to find and create stamps for all of the images. Once the stamps are displayed in the Viewing Window, users can right-click on an outline to either render the image (display the image data in JMARS) or view the image in a web browser.

Description
Basic Parameters

Image ID(s)

Any Specific Image ID Number(s)

A unique identifier for each image commanded; follows the pattern PPP_NNNNNN_TTT_COLOR, where:

  • PPP is a mission phase descriptor
  • NNN is the six-digit, zero-padded orbit number
  • TTT is a four-digit zero-padded chronologically ordered target number within an orbit.
  • COLOR is either "RED" or "COLOR" based on the filters used.

Min/Max Longitude

0 to 360(East Longitude = Positive)
Blank(Any Longitude)

 This is the approximate longitude on the planet Mars of the image center. All values are based on the IAU 2000 aerocentric model of Mars with east positive longitude.

Min/Max Latitude

90 to -90(North Latitude = Positive)
Blank(Any Latitude)

 This is the approximate latitude on the planet Mars of the image center. All values are based on the IAU 2000 aerocentric model of Mars with north positive latitude.

Min/Max Orbit

1 - ~19000 (as of 9/9/10)
Blank(Any Orbit)

 MRO orbit during which the image was acquired.
Advanced Parameters

Mission Phase

PSP - Primary Science Phase

ESP - Extended Science Phase

Transition - Aerobraking Phase

Blank - All Mission Phases

 The MRO/HiRISE mission has been divided into the following phase.

Min/Max Map Scale

0.25 - 2.50 (in meters/pixel)
Blank(Any Map Scale)

 Spatial resolution (in pixels per meter) at the center of the image.

Min/Max Lines

0 - 202,200
Blank(Any Number of Lines)

 The number of horizontal lines of pixels contained in the image.

Min/Max Line Samples

0 - 181700
Blank(Any Number of Line Samples)

 The number of pixels in each line of the image.

Min/Max Solar Longitude

0 - 360(0=Northern Vernal Equinox)
Blank(Any Solar Longitude)

This is the position of Mars relative to the Sun measured in degrees from the vernal equinox (start of northern Spring). This number is used as a measure of Martian seasons. (Also known as heliocentric longitude and abbreviated Ls.)

  • Northern Spring/Southern Autumn start at 0°
  • Northern Summer/Southern Winter start at 90°
  • Northern Autumn/Southern Spring start at 180°
  • Northern Winter/Southern Summer begin at 270°

Min/Max Local Time (24hr)

00:00-24:00 - Given as HH:MM in Mars time
Blank(Any Local Time)

 This is the local time on Mars at the center of the image relative to a division of the martian day into 24 equal parts. A martian day is slightly longer than 24 hours and 37 minutes long.

Min/Max Solar Incidence Angle

0 - 180(0=Sun Directly Overhead)
Blank(Any Incidence Angle)

 Derived for the center of the image, this is the angle between the Sun and a "normal" drawn perpendicular to the planet's surface at the time the image was acquired. A higher incidence angle means that a person standing on the ground would see the sun lower toward the horizon.

Min/Max Emission Angle

0 - 180(0=HiRISE Directly Overhead)
Blank(Any Emission Angle)

 Measured from the center of the image, this is the angle between the HiRISE and a "normal" drawn perpendicular to the planet's surface. In most cases, the HiRISE is looking "straight down" and the emission angle is thus close to 0°.

Phase Angle

0 - 180(0=HiRISE and Sun In-Line)
Blank(Any Phase Angle)

 This is the angle between the sun, the surface, and the HiRISE at the time the picture was obtained.

Slant Distance

0 - 5000(Distance from sub-MRO point to image center, in meters)
Blank(Any Slant Distance)

 This number is similar to the spacecraft altitude, but also takes into account the emission angle. If the emission angle is 0 then this number is the same as the spacecraft altitude. If the emission angle is much greater than 0, then the "slant distance" to the surface at the center of the image is also greater than the spacecraft altitude.

Stereo Flag

Yes - Image is part of a Stereo Pair
No - Image is not part of a Stereo Pair
Blank - Any Stereo Flag

 Designates which images are part of a stereo pair.

Rationale Description

Any Text
Blank(Any Rationale Description)

 A short description of why the image was targeted.

Stamp Layer Functions

The HiRISE Stamp Layer's functions are identical to the functions of the Stamp Layer and are explained in detail on the Stamp Layer page.
