Wildnote vs SoilHue

Wildnote is The Environmental Consulting Platform for customizable cloud-based data collection, management, and reporting. It has pre-built forms and reports for a broad spectrum of environmental consulting disciplines, yet can be customized to support complex workflow, reporting, and branding needs. Established workflows for USACE Wetland Delineations, SWPPP, Construction Compliance, Cultural Resources, Paleontology, Endangered Species Monitoring, Mitigation Banking and Restoration and more. From mobile data collection and photo management, to frustration-free reporting, Wildnote automates your processes while improving your project efficiency by 40-80% allowing you to deliver faster, more accurate regulatory-compliant reports with project transparency. Key Mobile App Features: -Works Offline -Integrated Photo Management -Extensive form library, or build your own forms for your project needs -Built-in taxonomy with scientific name, common name and indicator status with taxonomy favorites -Built-in Munsell soil colors -Upload associated project documents and reference materials -Works with Trimble R-1, Trimble Catalyst, EOS Arrow, Bad Elf Pro, Juniper Geode Regulatory Data Collection for: -All 10 USACE Wetland Regions with built-in calculations -Ordinary Highwater Mark (Arid West and Interim) -California Rapid Assessment Method -Cultural Resources SHPO Solutions for California, Nevada and Utah with flexibility for all states.

SoilHue identifies the Munsell color of a soil sample from a photograph taken with your device. It is built for pedologists, agronomists, geologists, archaeologists, conservators, soil-science students and anyone who works with soil color in the field. WHAT IT DOES • Calibrate the camera with an X-Rite ColorChecker Classic. SoilHue detects the card automatically inside your photo, rectifies its perspective, and computes a 3×3 correction matrix by least-squares fit over the 24 reference patches. • Take a photo of your soil sample (or pick one from your library) and select the area to analyze with a rectangle or a free-form polygon. • SoilHue averages the selected pixels in linear sRGB, applies your calibration matrix, and finds the closest match in CIE Lab among 293 chips derived from the official USDA Munsell renotation data. • Get the Munsell notation, an approximate USDA soil order (Histosol, Mollisol, Alfisol, Oxisol, Vertisol, Spodosol, Aridisol, Entisol, Inceptisol, Ultisol) and a short description. WHAT'S NEW IN 2.0 • 293 reference chips instead of 18. • ΔE94 in CIE Lab instead of Euclidean RGB. • Matrix 3×3 calibration replacing per-channel factors. • Automatic ColorChecker detection (Vision framework). • Printable calibration card (2-page A4 PDF, ICC sRGB). • Lighting check (warm/cool/atypical tint warning). • Real .xlsx export. • Accessibility, dark mode and stability improvements. DATA & PRIVACY • All analysis runs on-device. No image, sample or location ever leaves your phone. • Samples are stored locally in your app sandbox. iCloud sync is planned for a future release. • Location is captured only when you explicitly grant it. REQUIREMENTS • iPhone or iPad running iOS 17.6 or later. • A reasonably calibrated camera. Recommended: X-Rite ColorChecker Classic for best results. A basic calibration card is included for casual use. NOTES The USDA soil order classification is a heuristic orientation, not a definitive diagnosis — real classification depends on horizon, chemistry, texture and other field properties. Calibrations saved with versions before 2.0 are not compatible with the new color engine; the app will ask you to recalibrate. Contact: soilhue@ajgb.eu — Web: ajgb.eu/apps/soilhue
