Most images (PNG and thumbnails) were generated with an equirectangular projection. Images that are near the poles have been projected with a polar projection.
We used Gaskell's shape model and the ISIS software routines to convert images into map-based projections.
About SBIB - Vesta
Vesta Mission Phases (from end to beginning) covered in SBIB
- TransC - Transfer from HAMO2 to Ceres (aka Departure)
- HAMO2 - A second High Altitude Mapping Orbit
- LAMO - Low Altitude Mapping Orbit; about 210 km
- TransL - Transfer from HAMO to LAMO
- HAMO - High Altitude Mapping Orbit; about 680 km
- TransH - Transfer from Survey orbit to HAMO
- Survey - Consists of a full and complete survey of Vesta; includes all FC filters and expansive VIR observations
Map Projection and Arc-GIS
Data can be imported into ArcMAP 10.1 by downloading the ISIS Map cubes.Most images (PNG and thumbnails) were generated with an equirectangular projection. Images that are near the poles have been projected with a polar projection.
Maps
We use several different overview maps for the Image Browser. References for each:- Topographic - Gaskell et al., AGU Fall Meeting (2011)

Data processing
We used the USGS software tool Integrated Software for Imagers and Spectrometers (ISIS) as the main tool to process the data.We used Gaskell's shape model and the ISIS software routines to convert images into map-based projections.
Coordinates
This software uses the PDS-Vesta-2012 coordinate system, as approved by the IAU (details). This system is also known as the "Claudia Double Prime."- Spin Pole of Vesta at RA=309.0 deg, Dec=42.2 deg
- Rotation period 0.2226 days (Drummond et al., 1998)
- Prime Meridian parameter W0=285.4 deg and Wdot=1617.33 deg/day
