Explore Mercury Orbital Data

Simple, interactive Web interface for Mercury maps is now available to the public!

Recent enhancements:

Completely new User Interface including 3D navigation!

MDIS and MASCS product updatesNew MLA and MDIS regional DEMs

http://messenger.jhuapl.edu/


ACT-REACT Quick Map allows users to:

• Navigate Mercury in 3D !

• Locate craters and other named Mercury features

• Explore global mosaics and mini-mosaics of targeted regions. Global mosaics are available for download.

• Explore Mercury topography with elevation profiles and DEM layers

• Locate orbital images within user-defined regions of interest (ROI) and download those images from PDS. Also access spectra and observation meta-data.

Featured Images from MESSENGER Website

QuickMap allows users to locate and link to the featured images and associated descriptions from the MESSENGER website. Example showing “Revisiting Boccaccio” featured image near Mercury’s south pole.

a.With MESSENGER featured images layer selected (Location Overlays group), click on Search text box.b.Enter full or partial feature name (“revisiting” for this example search, on South Pole view) and click on Find. Results are listed below where you entered search text and marked by orange rings in display. Features are highlighted in yellow as the cursor is hovered over their names in results list.

c.Click on image of interest in results list to navigate to a higher-resolution view.d.Click on the featured image ring to display the image and associated description from the MESSENGER website.

MASCS/VIRS Global Mosaics

MASCS/VIRS global mosaic layers are now updated to show the latest released data sets.

Monochrome mosaic

Color (Multispectral) mosaic


XRS Composition Maps

Latest global composition maps layers (showing element weight ratios) are available.

Al/Si

Ca/Si

Fe/SiMg/Si

S/Si


WIDE tool sample layer

A sample layer from the WIDE (Water Ice Data Exploration) tool has been included. It shows radar bright patches (in red shades) that are a signature of water ice presence. (Best viewed on the north polar projection)

Additional Elevation Models

New Digital Elevation Model products are available: MLA North Polar DEM and four DEM quadrangles from DLR (German Aerospace Agency).

East illuminated map

MDIS Global Mosaics

These global mosaics were assembled from images acquired at high solar incidence angles (average >70°), illuminated from the east and from the west, to highlight topography and surface morphology.

Updated global mosaics with high incidence illumination (big shadows)

Sun from East

Sun from WestWest illuminated map


MDIS Global Mosaics

This global mosaic was assembled from images illuminated at minimized solar incidence angle to accentuate albedo variations.

Updated global mosaic with low incidence illumination (no shadows)


Master Target Mosaics

To view mini-mosaics of images satisfying targeted observations, select MDIS Regional Targeted Mosaics (RTM) layers at resolutions of 1000 meters per pixel or higher.


Regional Target Mosaics

Regional mosaics of enhanced observations pointed at special regions of scientific interest, like features for which higher-resolution morphological or multispectral imaging or denser spectral sampling could help in geological characterization, hypothesis testing or creating context for other MLA and MASCS observations.

names are approved by the IAU !

Mercury Features Layer

Example view of larger features among over 400 International Astronomical Union (IAU) approved named Mercury features. Smaller features are displayed in higher resolution views. Close features are clustered when zoomed out. Features names are displayed at 500 m/pixel or higher resolution. See next slides for feature searches and higher resolution example.

Mercury Feature Searches

Example Mercury feature search yields features with names containing search text “mo” – shown in results list on left and with orange rings on map display. Hovering the cursor over a feature in the results list highlights that feature in yellow on map display. Clicking on Mozart in the Search Results list navigates to higher resolution view of that crater – see next slide.

a.With Mercury features layer selected, click on Search text box.b.Enter full or partial feature name (“mo” for this example search) and hit Enter. Results are listed below where you entered search text and marked by orange rings in display. Features are highlighted in yellow as the cursor is hovered over their names in results list.

c.Click on feature of interest in resulting list to navigate to a higher-resolution view of that feature.

Search for named Mercury features:


Navigating Mercury Features

High-resolution view of Mercury Mozart crater navigated to via Quick Map Mercury feature search (as described on previous slide). Clicking on feature provides IAU information shown.


Polygon (ROI) Searches

Example search for images in user-defined region of interest (ROI). Links are provided to download images from PDS. Users can also search for targets and MASCS/VIRS observations in an ROI.

1. Enable Polygon tool

a.Draw ROI polygon by click-and-dragging mouse on map; end drawing by double-clicking.b.Click on the ‘Query Feature’ / MDIS Mosaic Imagesc.Search Results window will appear, listing requested results in ROI. Search can be iterated on same ROI for 750-nm mosaic images, all NAC images, and all WAC images.d.Links in search results: rightmost links enable image file download from PDS. Leftmost links indicate PDS image filenames which when clicked provide additional image meta-data.

2. Search for images in ROI
