Hazard Exposure Assessment Dashboard

A personal workflow tool to speed up and standardize hazard exposure assessments for geographically distributed asset portfolios. This case study is independent and uses only public-domain, synthetic, or sanitized examples.

Highlights

What this dashboard is designed to achieve and how it's structured.

Objective

  • Reduce manual steps when assessing tens to hundreds of sites.
  • Produce decision-ready outputs: exposure metrics and clean visuals.
  • Improve consistency using a repeatable, standardized workflow.

Approach

  • Ingest asset locations and selected hazard layers.
  • Automate overlays and summarization into exposure indicators.
  • Generate maps and charts for interpretation and reporting.

Tools

  • Streamlit for the interface and modular workflow steps.
  • GIS overlays and spatial joins for exposure extraction.
  • Python for preprocessing, automation, and batch processing.

My Role

  • Designed the end-to-end workflow and information architecture.
  • Defined exposure metrics and standardized output formats.
  • Built as a personal optimization initiative, not a client delivery.

Key Takeaways

  • Faster, more scalable assessments for distributed portfolios.
  • Standardized outputs reduce rework and improve cross-project consistency.
  • Clear visuals help communicate results to non-technical stakeholders.
Module 01

Inputs

Set up the assessment by loading asset locations and selecting hazard layers and analysis parameters.

  • Upload or define asset locations as points or a site list.
  • Select hazards and configure analysis settings such as buffers and thresholds.
  • Validate inputs upfront to reduce rework downstream.
Dashboard Inputs module: asset upload and hazard selection interface
Module 02

Run

Execute spatial overlays and summarization to compute exposure indicators consistently across entire portfolios.

  • Automated spatial overlays and joins across selected hazard layers.
  • Standardized aggregation into per-asset exposure metrics.
  • Repeatable workflow scaling from tens to hundreds of sites.
Dashboard Run module: spatial overlay execution and progress view
Module 03

Results

Review decision-ready outputs — metrics and visuals — then export results for reporting packs.

  • Portfolio-level summaries: counts and percentages by hazard class.
  • Maps and charts to communicate spatial patterns clearly.
  • Export tables and figures ready for client reporting.
