Portfolio of Work

Case study 1
Crime Dot-density Map for City of Chicago
Client: City of Chicago, University of New York at Buffalo via Chris Pappas-Ford, Geospatial Manager
Location: Remote
Scope of Work:
- Engineered advanced geospatial crime statistics maps for the city of Chicago, integrating multi-dimensional datasets.
- Analyzed and synthesized census demographics, meteorological data, and reported crime incidents to produce spatially precise dot density maps.
- Systematically classified criminal activities into violent and non-violent categories and further disaggregated by typology, such as arson, battery, and theft.
- Conducted quantitative spatial analysis to identify correlations between increased violent crime rates and warmer weather patterns in low-income areas
Outcome:
Developed probabilistic models leveraging integrated crime, climate, and population data to predict crime occurrence, temporal distributions, and spatial risk zones.

Case study 2
Janus Project – Global Geospatial Mapping Initiative
Client: NV5, Maxar, Wiser via Chris Pappas-Ford, Geospatial Manager
Location: Remote
Scope of Work:
- Conducted a comprehensive spatial analysis of Earth's surface, integrating multi-modal transportation networks and terrain classifications.
- Applied high-resolution mosaic ortho-imagery to perform land cover classification, distinguishing ecological and anthropogenic features such as evergreen and deciduous forests, barren landscapes, and urban residential zones.
- Geocoded and digitized transportation corridors, including pedestrian pathways, arterial roadways, subterranean and elevated transit systems, and multi-modal infrastructure for precise spatial representation.
- Utilized advanced 3D geospatial modeling environments to process, manipulate, and refine LiDAR datasets, enabling high-fidelity terrain reconstruction and topographic analysis.
Outcome:
Created a detailed 3D map of the planet's surface using LiDAR technology, which focused on documenting Earth's current state to aid conservation, research, and future planning. Along with assisting with the Seabed 2030 Project, which seeks to map the entire ocean floor by 2030, using crowd-sourced sonar data to understand underwater topography and currents.

Case study 3
Repair Underground Gas Network Project
Client: Texas Gas via Chris Pappas-Ford, Geospatial Manager
Location: Texas
Scope of Work:
- Digitized and repaired underground gas pipeline networks across Texas, with a focal study on El Paso for spatial accuracy and infrastructure resilience.
- Coordinated with field teams to integrate real-time data updates into geospatial models, enhancing dynamic workflow precision.
- Conducted detailed analysis of blueprints and as-built documentation to determine pipeline geometry, spatial location, and material characteristics for optimized asset management.
- Developed a comprehensive strategy for pipeline service optimization and network management, employing predictive geospatial methodologies to mitigate disruptions caused by winter freeze events in Texas.
Outcome:
Enhanced the underground gas pipeline network across Texas by repairing infrastructure and resolving discrepancies in pipeline data, including shell type, geometry, and location. Streamlined response processes to improve efficiency, reducing resolution times for One Gas customers experiencing utility-related issues. Created plans for upgrading and replacing old or insufficient gas lines with newer materials that met current standards for safety and capacity. This included extending the pipelines to accommodate new appliances, increasing their diameter for higher gas flow, or upgrading materials for longevity and reduced risk of leaks.
