Description

Calculates the latitude and longitude bounding box of all cubes in a directory. Used in making mosaics.

Arguments and Return Values

Arguments: a filelist, file suffix, band number and a directory

Return Value: a v_object containing the bounding coordinates of all cubes in the filelist

Usage

Syntax: bounding_box(filelist, suffix, band, dir [,geo = BOOL])

The filelist must contain one filename per line. The file_suffix must be the suffix of all files in the filelist. The THEMIS cubes must contain the band specified.

geo - use a Geo-Struct compatible file instead

Examples

 dv> a = read_lines("file_list")
 Text Buffer with 2 lines of text
     1: V09277003
     2: V10812002

 dv> b = bounding_box(a,".qub",3,"/work/bob/mosaic")
