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
  • forcingdata
• 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:

For local:

STORE_TYPE='LOCAL'

For S3:

STORE_TYPE='S3'
AWS_ACCESS_KEY_ID='**************'
AWS_SECRET_ACCESS_KEY='**************'
AWS_DEFAULT_REGION='us-east-1'
S3_BUCKET='******'

• Select the stage in docker-compose.yml file
• 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>

GET /forcingdata?definition_file=<s3_key>

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