ARSLAB Research Assistant Internship

June 2020 to December 2020

Welcome

This repository will provide some background into the work I was a part of during my internship at ARSLab. The documentation for each work is held inside their respective repository. In some areas I’ve included PowerPoints to provide further background.

Types of Work

GIS

GIS Simulation Explorer (GSE)

A GIS environment based visualization for large scale spatial simulations on the web.

Direct Links

End Goal

Have one version (V1 –> V2)
GSE integration with DEVS Web Viewer
Build library of “toy” models
- Requires server use, hence the move from V1 to V2
Only visualize data within browser window view instead of loading everything
Improve thematic mapping
- Choropleth
- Proportional
- Heatmap
Refactor code and clean up UI

Differences between V1 and V2

User Interface
- V1
- V2
Data Loading
- V1 (in the sidebar)
  - Local (requires file chunking to read large files)
- V2 (in a separate page)
  - Server (fetch and / or send)
Simulations
- V1 can support multiple simulations at the same time
- V2 only lets you upload one simulation per browser tab
Vector data
- V1 only displays polygons
- V2 can display various geometries (polygon and centroids)
Customization
- V1
  - Limited customization of color and classification from user interface
- V2
  - Application.json provided by programmers
  - Visualization.json provided by end users

Additional Background

Spatial Analysis Scenarios

The goal was to develop a method that automates the generation of large-scale, spatial DEVS simulation models from GIS data. The repository explores various scenarios related to emergency services, disaster responses, and urban logistics. Having technical experience with Python, and QGIS was helpful.

Additional Background

Spatial Autocorrelation Statistics

Background into spatial autocorrelation statistics and use of GeoDa specialized software. The repository might be useful for reviewing the Zhong model.

Autodesk Forge Viewer

COVID-BIM

Used BIM data to simulate the spread of viral aerosol in buildings. See the old version in action at the AEC Hackathon. See also BIM-to-DEVS for an even older version.

Additional Background (slightly out of date)

COVID-GAME-APP

A COVID game simulator as a real-world application that could train industry practitioners to improve ventilation or spatial design, make informed risk assessments, observe contact tracing, and discover new ways to conduct facilities management. Presented a demo at Autodesk University Forge Hackathon 2020.
