GIS Spatial Evidence Analysis & Forensic Mapping for Criminal Defense
Turn fragmented location, timing, movement, and cell-location evidence into clear visual analysis that helps attorneys evaluate and illuminate patterns among routes, timelines, feasibility, case data and competing narratives.
Travel & Timing: Could the documented movements fit the available time?
Travel & Timing
Compare routes, travel times, distances, and whether documented movements fit the available timeline and sequence of events.
Location Evidence
Examine cell-location records, traffic and surveillance cameras, GPS/vehicle records, and other location-based evidence.
Witness Visibility
Evaluate sight lines, distance, obstructions, lighting, and other viewing conditions that may affect what a witness could observe.
Cell Signal Estimates: Could proximity to a cell sector explain pings that fall outside the prosecution’s estimated coverage area?
Location Evidence: What do the records actually establish about where someone could have been?
Witness Visibility: Could distance, traffic, and construction obstructions have limited the witness’s view?
1. Case Assessment
Review the issue, available evidence, deadlines, and whether GIS analysis is likely to help.
2. Scope & Estimate
Define the analysis, exhibits, deliverables, timing, and cost before work begins.
3. Analysis & Exhibits
Organize the evidence, perform the spatial analysis, and prepare clear visual exhibits.
4. Findings & Delivery
Deliver completed exhibits and, when included, a concise report with methodology, assumptions, and limitations.
Demonstration examples are simulated to protect case confidentiality.
