Generator for Indoor-Outdoor Graphs (GIO.G)

GIO.G is an open-source and configurable tool designed to streamline the modeling process and reduce manual effort, enabling researchers and practitioners to focus more on scenario exploration and analysis. GIO.G offers a systematic and automated approach to generating Indoor-Outdoor Graphs based on user-defined environmental parameters. This scalability extends to large environments, making GIO.G suitable for a wide range of urban modeling applications. The details of the information can be found in our paper: <TODO: Link to paper here>.

Prerequisites

Scala version 2.13.13
Sbt version 1.9.8

Running - Web Interface

In order to run our web interface, run sbt run from the root directory. Then go to http://localhost:9000 to see the running web application.

To simplify running the web interface, we have also included a dockerfile to run GIO.G in a docker container.

1. Build Image

   docker build -t gio.g .
   

2. Start Container

   docker run -it -p 9000:9000 gio.g
   

Running - Command-line Interface

If you'd rather use the graph generator itself, without the web interface:

1. First you will need to move to the cli folder:

   cd cli

2. Run the GIO.G through the sbt build tool

   • Output usage text detailing all the ways to use the CLI app

     sbt "run"

   • Output example graph with default configuration

     sbt "run --default --format json"
