v1.0.0

Updates

• Workflow orchestration: WorkflowManager.py and the configuration manager were moved into the pdgworkflow package to orchestrate the companion packages: viz-staging, viz-raster, and viz-3dtiles.
• Multi-layer WMTS: WMTSGenerator now creates a single WMTSCapabilities.xml that includes multiple layers in one pass.
• Build tooling: migrated project setup from Poetry to uv.
• Custom TMS support.

Additions

• Faster stats access: statistics previously written to CSV are now also duplicated to Parquet for faster reads and downstream analytics.

v0.9.3

Updates

• Visualization workflow config for processing the Arctic infrastructure dataset
• Python environment used for processing the Arctic infrastructure dataset

The viz-workflow package was designed to process geospatial datasets for visualization on the Permafrost Discovery Gateway, an online platform for big data creation and discovery to support knowledge-generation. There are known areas for improvement, and the codebase is currently under development.

Datasets and metadata are archived on the Arctic Data Center. Datasets can be standardized and visualized with Permafrost Discovery Gateway packages, such as viz-staging, viz-raster, and viz-3dtiles via the viz-workflow package. These packages produce derived datasets that can be used for future research, education, and more.

v0.9.2

Updates

• generalized workflow script to import and process appropriate workflow configuration and input datasets
• Updated README documentation

Additions

• Added code for processing Arctic infrastructure dataset
• New CONTRIBUTING documentation

The viz-workflow package was designed to process geospatial datasets for visualization on the Permafrost Discovery Gateway, an online platform for big data creation and discovery to support knowledge-generation. There are known areas for improvement, and the codebase is currently under development.

Datasets and metadata are archived on the Arctic Data Center.

v0.9.1

New configuration for new dataset processing

• Created a new workflow configuration file and workflow processing script for a dataset for pan-Arctic lake area time series
• Updated rsync scripts to import the new configuration file

The viz-workflow package was designed to process geospatial datasets for visualization on the Permafrost Discovery Gateway, an online platform for permafrost big data creation and discovery to support knowledge-generation. There are known areas for improvement, and the codebase is currently under development.

Datasets and metadata are archived on the Arctic Data Center. The datasets created with PermafrostDiscoveryGateway/viz-staging can be further processed with other Permafrost Discovery Gateway packages, such as viz-raster and viz-3dtiles, via the viz-workflow package.

Viz-workflow Initial Release

This version of viz-workflow was designed to process geospatial datasets for visualization on the Permafrost Discovery Gateway, an online platform for permafrost big data creation and discovery to support knowledge-generation. This version of viz-workflow was used to process the ice wedge polygon dataset visualized on the Permafrost Discovery Gateway, in addition to other Arctic datasets. There are known areas for improvement, and the codebase is currently under development.

Datasets and metadata are archived on the Arctic Data Center.
