Extracting and Visualizing (unmapped) Bit Flags from Byte Data.

Bitflag Visualizer Sample Image

Program Name: Bitflag Visualizer

Program Description: This IDL program extracts bit flags from byte data arrays, and then plots them (unmapped) using a 23-color discrete color bar. The specific codes are designed to extract any Runtime QA bit flag and/or 35_L2 Cloud Mask bit flags.

Language and Environment Requirements: IDL.

Limitations: IDL must be installed. User must have x-window display capability. HDF file must be visible to local machine.

Run Tips: Edit the main IDL program "bitflag_visualizer", modify user specified input lines to select HDF file, Scientific Data Set (SDS), and specific bitflags to visualize.

Developer: Paul A Hubanks (NASA GSFC)

Current Version (Release Date): Version 2.0 (June 2005).
