The misr_envi tool imports MISR Level 1B2 Ellipsoid and Terrain stacked block data into ENVI. The data are automatically geolocated and the band information is correctly interpreted, improving the way ENVI understands such files and presents their contents. An extension to the tool reads and geolocates the Land BRF parameter from a MISR Level 2 Land Surface data file.

The tool consists of a set of routines written in Exelis Visual Information Solutions IDL programming language which implements an ENVI User Function for working with MISR L1B2 data. MISR map projection definitions are provided for augmenting the ENVI defined map projections file, and a sample ENVI menu file which adds a menu item to invoke this tool is also included. The tool runs in ENVI version 4.0 and higher.

Additional information, including installation and program execution instructions, is available in the Users Guide (MS Word Users Guide | PDF Users Guide).

The misr_envi tool software can be downloaded as a tar file containing all twelve files, misr_envi.tar (713 KB) or the files contained in the tar file can be downloaded separately.

The Level 2 BRF extension can be downloaded as a tar file containing seven files, misr_envi_l2brf.tar (25 KB), including a README text file with Installation instructions.
