Echospectra Raising the Standard in Wildfire Investigation Echospectra is the field-ready documentation platform built for wildfire origin and cause (O&C) investigators. Designed by fire professionals and data scientists, it replaces paper forms, GPS units, and disorganized photo logs with one structured, defensible workflow that works entirely offline. Our mobile and desktop tools enforce indicator discipline, auto-link every image to its location and compass bearing, and export courtroom-ready reports in a single click—reducing documentation time by up to 80% while improving consistency, accuracy, and legal defensibility. Built for the Field Capture indicators, areas, and transition zones directly on the map. Each record automatically stores GPS coordinates, azimuth, timestamps, and author metadata. Cached maps and offline syncing keep you working anywhere—even miles from coverage. Scientifically Defensible Echospectra aligns with NWCG PMS 412 documentation standards, preserving full chain-of-custody and metadata integrity. Every change is tracked with an auditable history, supporting both internal QA and expert testimony. Efficiency Meets Clarity Investigators collect more comprehensive data in two days with Echospectra than a week using traditional methods. Structured exports—photo logs, KML, and original images—turn fieldwork into clean, shareable case files that withstand scientific and legal scrutiny. Key Capabilities • Structured indicator mapping aligned with NWCG standards • One-click, defensible photo logs with GPS, azimuth, and timestamps • Layered, shareable maps with offline reliability • Export-ready case packages for QA and litigation • View-only and scoped-edit sharing for clients or teams • Optional property, weather, and lightning layers (Pro tier) Trusted by Experts Validated through multi-agency field use and recognized at the 2025 Wildfire Ignition Causes Conference, Echospectra is built for investigators who demand clarity, defensibility, and speed in the field. Field-fast capture. Teamwide clarity. Data you can defend. Download Echospectra today.
Hydrant Flow Test Calculator
This tool simplifies hydrant flow testing by calculating total GPM from pitot pressures. It allows for outlet settings, flow extrapolation with a Supply vs Demand curve, and plotting demand points for PASS/FAIL results. Save test data with location and project details for future reference.

Hydrant Flow Test Calculator is a field-friendly calculation and reporting tool for fire protection professionals, engineers, inspectors, contractors, and AHJs who need to evaluate and document hydrant flow test results. The app helps calculate hydrant flow from field readings, compare available water supply against system demand, estimate downstream friction loss, and export professional PDF reports. Key features: • Calculate hydrant flow using static pressure, residual pressure, pitot pressure, outlet diameter, and discharge coefficients • Calculate total test flow and flow at a target residual pressure • Compare available supply against system or pump demand • Review demand pass/fail results with available pressure and safety cushion • View Supply vs Demand graph with demand point legend • Save completed test records to History • Add project information including associate, project number, project location, test hydrant tag, and flow hydrant tag • Optionally capture test hydrant and flow hydrant coordinates • Attach an image to a saved test record • Export PDF reports with project details, test summary, demand results, graph, location details, friction loss results, and attachment • Estimate friction loss using pipe product, nominal pipe size, inside diameter, pipe length, C-factor, elevation, minor loss, and device/backflow loss • Supports US and SI flow display The Friction Loss tool includes pipe product and nominal pipe size selection with automatic inside diameter lookup. Elevation guidance helps users enter positive values for uphill and negative values for downhill conditions. Hydrant Flow Test Calculator is designed to make field calculations faster, improve documentation consistency, and help organize hydrant flow test information in one place. This app is intended as a calculation and documentation aid. Users are responsible for verifying all inputs, assumptions, calculations, and results according to applicable codes, standards, project requirements, and professional judgment.
