mcat-ras

Contains the HEC-RAS model content and analysis tool (MCAT). Given a .prj file, this MCAT identifies paths to the plan, forcing, and geometry files and extracts the model's metadata and geospatial data.

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-RAS files.
  • docker-compose.yml: options for building the dockerfile.
  • main.go : API Server.

Getting Started

  • Add a .env file to the root level of this directory with the following structure: 
    AWS_ACCESS_KEY_ID='**************'
AWS_SECRET_ACCESS_KEY='**************'
AWS_DEFAULT_REGION='us-east-1'
S3_BUCKET='******'
  • Run docker-compose up
  • To teardown, run docker-compose down

MCAT REST Specification

The following requests can be used to interrogate a model whose storage location is defined by the s3_key parameter:

GET /isamodel?definition_file=<s3_key>

GET /modeltype?definition_file=<s3_key>

GET /modelversion?definition_file=<s3_key>

GET /index?definition_file=<s3_key>

GET /isgeospatial?definition_file=<s3_key>

GET /geospatialdata?definition_file=<s3_key>

For example: http://mcat-ras:5600/isamodel?definition_file=models/ras/CHURCH HOUSE GULLY/CHURCH HOUSE GULLY.prj
