============================================= nagg version 1.0.0 released on Feb 17, 2012 ============================================= 1. Introduction =============== This document describes the NPP Aggregation tool, nagg, and contains information on the platforms tested, changes since last release and any known problems. If you have any questions or comments, please send them to: help@hdfgroup.org 2. Platforms Tested =================== Linux 2.6 32bit and 64bits with gcc 4.1.2 3. New features and bug fixes since Version 0.0.1 ================================================= Configuration ------------- - [None] Features -------- - Output files are aligned with the bucket boundry as defined in the Control Book. Fill granules are added when there are no granules available for "slots" in a bucket. Leading and trailing fill granules are not generated for the first and last output files respectively. Therefore, first and last output files may be partial files that consists of granules fewer than requested. - Geolocation file names can be approximate such that only the beginning parts up to creation date are matched. E.g., if the sensor data files define its geolocation file as: GMTCO_npp_d20100906_t0701368_e0703013_b00004_c20111024161933653314_noaa_ops.h5 the tool will accept any file matching this pattern acceptable and will use the one with the latest creation date. GMTCO_npp_d20100906_t0701368_e0703013_b00004_c*.h5 Limits ------ - See nagg.docx (html, pdf) in the same directory for proposed functionality. Current release has the following limitations: * Environment variables or command line options for compliance with file naming convention presume valid types and packaging as defined in the "nagg.h" file. * Grouping by time rather than number of granules (-A flag) is not supported (e.g., 7 minute 59 second granules starting at a given time rather than just at the earliest granule encountered.) * Warnings or failures if granule gaps exceed some threshold are not supported. * Compression on output is not supported. * Options to choose repair granule are not supported; for now, the one with the latest version is used. * Option to replace existing granule with repair granule is not supported. * Restrictions on flags and input parameters: Directory input is not supported. -t - only one single type is supported. -l - not supported -A - not supported -S - not suported -d - not suported 4. Known problems ================= [none]
