GPKG Time Series Format Specification

The below section lists the TUFLOW GPKG time series format specification. The specification sits ontop of the GPKG v1.2 Specification with two additional required tables. The below lists the details of the additional tables with examples. The examples are based a the TUFLOW-SWMM linked example model based on TUFLOW's module 6 tutorial model - M06_5m_003.tcf.

GIS Layers

The results are stored in GPKG layers, typically between 1 - 3 layers are stored in the result file depending on the output (one for point results, one for line results, one for polygon results). However there is no requirement against storing results from multiple model runs in a single GPKG, this is just not typically how outputs are written.

Requirement 1

The GPKG layers should have the following columns:

In this example the GIS layers are M06_5m_003_swmm_ts_L and M06_5m_003_swmm_ts_P.
