About the webinar

Public Safety continues to evolve with technology. Is your organization keeping up? Our expert speakers discussed how innovative organizations use drones and Pix4D software to smooth workflows, uncover previously hidden data, and recreate accident scenes.

With real-world case studies from some of the world’s most innovative Public Safety organizations, this webinar covered the practicalities of gathering data (even when you don’t have a drone), the legalities of collecting and using imagery, and how Pix4D can be used to get the information your team needs.

Expert guest speakers, Mark Johnson, Founder and President of Visual Law Group, and Walter Chomentowski, Geospatial Intelligence Specialist from Michigan State Police, shared their experience using drones and Pix4Dmapper photogrammetry software.

Sam Pepple has been a geospatial professional for over 10 years. He started his career as a cartographer, making clear, concise, and compelling maps from complex data. For the past five years, he has been creating his own data with photogrammetric means. Before working for Pix4D, he created measurable 3D data of critical infrastructure for the AEC industry. At Pix4D, Sam has been focused on using photogrammetry for accident and crime scene reconstruction, working with Public Safety agencies (local, state, and federal) to help them best utilize this technology to create accurate and evocative data from photos.
