Welcome to the Vortex wiki!

Vortex is a collection of data processing utilities targeted for Hydrologic Engineering Center applications, e.g. HEC-HMS. The Vortex API uses NetCDF Java and GDAL libraries to perform operations on spatial data.

The importer utility takes NetCDF, Grib, HDF, ASC, or HEC-DSS files as input, gives the user options for clipping, re-projecting, and resampling data, and writes to HEC-DSS format.

The grid-to-point-converter utility converts gridded data to basin-average time-series data.

The time-shifter utility shifts grids in time.

The normalizer utility normalizes volumes from one set of grids to another, e.g. normalize hourly QPE grids to daily PRISM grids.

An example of batch scripting with the vortex API has been posted here.
