These CLI tools are used to manage hazard datasets and their metadata.

Please see Hazard dataset overview for context about the hazard datasets themselves.

Import workflow

For hazard calculations:

• ths_compat to list or maintain compatablity keys (these hopefully rarely change)
• ths_rlz_import producers to ensure latest producer configs are available in THS/resources.
• ths_rlz_import rlzs to extract openquake hazard curves as a parquet dataset.
• ths_rlz_sanity count_rlzs to count realisations in a parquet dataset.

See Aggregation CLI workflow for a detailed example of the above.

Migration workflow

For migrating from older NSHM_v1.0.* calcuations we use the same Import workflow (see above) , then:

• ths_rlz_sanity random_rlz_new to compare random hazard curves with new datasets

Utilities:

• ths_defrag to reorganise and optimise hazard datasets.
• ths_check to verify equivalence of two hazard datasets
• ths_filter to create a subset dataset from a larger one.
• ths_query run simple queries on a hazard dataset.
