NASAView Image Display Software

NASAView is a PDS archive product display program that runs on multiple platforms in a GUI environment. This application was built using the Label Library Light (L3), Object Access Library (OAL) and the XVT Development Solution for C package. Label Library Light parses PDS ODL labels and creates an in-memory representation of the label information. The Object Access Library uses the parse tree and accesses the actual PDS object. The XVT Development solution supplies the cross-platform GUI support and an object-oriented environment.
