Welcome to the very first EmberCast, a new short-form addition to the Fire Investigation INFOCUS Podcast. These mini-episodes are designed to spark curiosity and deliver timely insights in between our full episodes. In this kickoff EmberCast, Chasity and Scott are joined by Jesse Sprague, founder of Echo Spectra, to talk about an innovative new tool for wildfire investigation. Jesse shares how his background in geology, computer science, and mapping led him to develop a free mobile app that allows investigators to document wildfire origin and cause scenes with precision. Built to align with the PMS 412 guidelines, the app enables users to capture directional indicators, tie them directly to photos and metadata, and export results into formats like Google Earth—complete with styled arrows, orientation, and photo logs.

Throughout the conversation, Jesse explains the app’s capabilities, from tracking advancing, lateral, and backing indicators, to overlaying wind vectors, lightning strike data, and land ownership information. He also shares upcoming features like polygons, boundary mapping, and turkey tracks to enhance scene documentation. Scott and Chasity highlight the value this tool brings to investigators at all levels—whether new to the field or seasoned experts—by consolidating critical data into one intuitive platform. With Echo Spectra’s blend of technology and fire science, investigators now have a powerful, accessible way to streamline their work and elevate their reporting.

This episode is a must-listen for anyone working in fire investigation, wildland fire response, or legal teams supporting fire cases. And the best part? The Echo Spectra app is completely free to download, making it an incredible resource for the community.
