Vertical Feature Mask Feature Classification Flag Extraction


Vertical Feature Mask Feature Classification Flag Extraction

This routine demonstrates extraction of the feature type information stored in a CALIPSO Lidar Level 2 Vertical Feature Mask feature classification flag value.

It is written in Interactive Data Language (IDL) as a callable procedure that receives as an argument a 16-bit feature classification flag value and prints the feature type information extracted from the bits in the flag value, as described in the CALIPSO Data Products Catalog.

Interactive Data Language (IDL) is available from Exelis Visual Information Solutions.
