In ENVI, you can assign map information to a PDS image based on values from the PDS label.
1. Download an image and corresponding PDS label file (.lbl extension) to the same directory.
2. Open the image in ENVI. It will not be map projected.
3. Select File > Edit ENVI Header and select the image. Click OK.
4. From Edit Attributes, choose Map Info...
5. Click Change Proj.
6. Unless you already have the correct lunar projection, create a new one (steps below assume projection does not exist).
7. Click New... on the Projection Selection dialog box.
8. Enter values based on label. For example, sphere radius 1738000 (notice in meters), projection type sinusoidal, 0 false
easting and northing, 74 central meridian longitude. (False easting/northing not in the label.)
9. Save projection and map_proj file. Select newly created projection.
10. In the Edit Map Information dialog, enter values from the label. For example, image coordinate x,y of 1.5,1.5 (the upper left
corner) might be 0,50 with pixel size of 400 m/pixel. Click OK to save map information and OK to save header.

In the MSL, MER, and Phoenix Analyst's Notebooks, standard data sets can be found in the sol summaries, but additional data sets can be accessed, as well.
These data sets can be located through Resources for Curiosity, Spirit, Opportunity, and Phoenix. Both the MER and Phoenix resources offer additional data sets, data set documents, and a reference list.
In MER's additional data sets, you can access:
- APXS Oxide Abundance Data
- MI Merged Focal Sections
- Pancam Atmospheric Opacity Data
- Rover Motion Counter Data
- Inertial Measurement Unit Data
- Traverse and Crater DTMs
- and Radio Science Orbit and UHF Data
In Phoenix's additional data sets, you can find:
- Robotic Arm (RA) Data
- Atmospheric Structure Experiment (ASE) Data
- Telltale Data
- and Surface Stereo Imager (SSI) Data
Both MER's and Phoenix's data set documents contain Data Set Software Interface Specification (SIS) documents, Mission and Instrument Description (Catalog) Files, calibration, and errata files. However, those for MER also include the MER Archive Plan and those for Phoenix contain the Phoenix Archive Plan.
The Phoenix resources also provide a map of the landing site, sol documents grouped by subsystem, and various web resources linking to the Phoenix Mars Mission, Planetary Data System (PDS), and related NASA websites. The MER resources further provide Mini-TES locator frames, Coordinate System Definitions, software, and suggestions for further reading.
