SeaDAS 11.0.0 Release Announcement - seadas/seadas-toolbox GitHub Wiki

SeaDAS 11.0.0 released April 13, 2026

Release Date: April 13, 2026

We are pleased to announce the release of SeaDAS 11.0.0.

Improved Data Handling – Correct support for L3m datasets that cross the dateline, improved handling of HARP2 and SPEXONE Level-2 products with 4D bands, and fixes for CZCS L2 image orientation.
Map Gridlines Enhancements – Improved rendering for global datasets and dateline-crossing scenes, with better labeling and performance for large-area visualizations.
Earthdata Cloud Spatial Subsetting – New OB_CLOUD Spatial Subset Tool retrieves Level-2 subsets from Earthdata Cloud via Harmony L2SS. Supports selection of individual 2D variables (e.g., chlor_a). When using variable subsetting, quality flags (e.g., l2_flags) are not included, and multi-dimensional variables (e.g., Rrs) are not supported. Spatial subsetting preserves full data and should be used for quality-controlled analysis.
Enhanced OB_CLOUD Data Browser – Added "Regions" selector for bounded geographic subsetting and improved integration with the Spatial Subset Tool.
GPT Cross-Platform Support – Graph Processing Tool (GPT) now fully functional on Windows, macOS, and Linux.
Platform and Installer Updates – Integrated with SNAP 13 and Java 21. Installers available with and without bundled JRE for Windows, Linux, and Apple Silicon macOS. Intel-based Mac support has been discontinued.
