mcat-hms

Contains the HEC-HMS model content and analysis tool (MCAT). Given a .hms file, this MCAT identifies paths to .control, .met, .basin, .grid, .dss, .sqlite, and .shp files and extracts the model's metadata.

The MCAT includes:

• a standard set of methods to evaluate a model's content:
  • isamodel
  • modeltype
  • modelversion
  • index
  • isgeospatial
  • geospatialdata
• an API for executing the above methods.
• a docker container for running the methods and API.

Contents

• /config: contains the data structure that holds the config information for the API.
• /docs: contains the auto-generated swagger files.
• /handlers: contains the handler function for each API endpoint.
• /tools: the core code used to extract information from the various HEC-HMS files.
• docker-compose.yml: options for building the dockerfile.
• main.go : API Server.
