✅ What’s New in Oasis Montaj 2025.2 (Top New Functions)

🟣 NEW Radiometric Extension (Modern sensors + guided best-practice workflow)

Oasis montaj 2025.2 introduces a completely modernized Radiometric Extension developed with Medusa Radiometrics, designed for today’s high-resolution gamma systems and easier “do it right” processing—even if you run radiometrics only occasionally. 🧠⚡

• 📡 Modern sensor support for high channel data (including sensors with 512, 1024, 4096+ spectral windows)
• 📘 Guided workflow aligned with IAEA standards from import → corrections → final results (transparent parameters at every step)
• ✨ NASVD spectral smoothing (industry-recognized) with guidance for parameter selection, plus low-pass filtering as an alternative
• 🤖 Fully scriptable workflow for repeatable processing, batch runs, and consistent team standards

Big change in 2025.2 ✅: The new Radiometric Extension replaces the older 256 Channel Radiometric Processing extension and the Praga extension—consolidating radiometric workflows into a single modern toolset. Praga is being retired (no longer available for sale/renewal), and maintained 256 Channel users automatically receive access to the new extension. 🔁✅

🟦 Gravity terrain corrections for high-resolution DEMs (Technical Preview + huge speed boost)

High-resolution DEM terrain corrections can be extremely demanding on desktop systems. With Oasis montaj 2025.2, users can (as a technical preview) perform gravity terrain corrections using Seequent Evo compute services, delivering approximately ~100× faster computations initially. ⚡🏔️

• 🧮 Offloads heavy calculations to compute services
• 🖥️ Keeps your workstation free for other tasks
• 🛡️ Helps reduce the risk of slowdowns/crashes when processing large terrain models and large survey areas

🟦 Improved gravity data processing (Best-practice tool)

• ✅ New Nettleton Cross-Correlation tool to compare multiple Bouguer anomaly densities and select the most appropriate value—supporting best practice and improving confidence in results

---

✨ Usability & Integration Highlights (Faster daily production work)

2025.2 also focuses on the small improvements that save time every day—especially when working under deadlines and managing large multi-channel datasets. ⏱️📈

• 🧭 Menus grouped by product → find tools faster and understand what’s included in each package/extension
• 📊 Row highlighting in databases → compare channels at a glance and reduce mistakes in multi-channel tables
• 🧩 Layer parameters from context menus (map + Map Manager) → faster troubleshooting and map editing
• 🛰️ ArcGIS Pro 3.3+ LYRX import → smoother GIS interoperability with fewer workarounds
• ☁️ Smoother Seequent Evo instance selection → easier setup and more consistent behavior across products

---

🔐 Identity & Licensing Updates (Bentley transition readiness)

As part of Seequent’s transition to Bentley Account and Entitlement services, Oasis montaj 2025.2 improves flexibility when choosing or switching identity providers during installation and use. The Seequent Connector is also updated to keep products accessible regardless of the identity provider selected. 🔑✅

🛠️ Bug Fixes & Stability Improvements (Notable fixes in 2025.2)

Oasis montaj 2025.2 includes important fixes that improve reliability, performance, and large-data handling. Here are some of the most useful real-world fixes: ✅

• 🖼️ Map raster export accuracy: high-DPI exports with “Auto Recolour Grid” now correctly match the on-screen map (no inconsistent tile colours)
• 📋 Database scrolling stability: channels no longer jump left/right after scrolling and selecting headers/cells
• 🧭 3 Model Tie points: georeferenced images now position/orient correctly in 2D maps and 3D views (tie points plotted accurately)
• 🔧 Update/installation fix: resolves the 2025.1 update issue “Unable to determine your license provider…” so 2025.2 installs and runs as expected
• 🧠 Large file memory leak resolved: RAM leaks during import/export/scanning of very large files (e.g., ASEG-GDF2) are fixed, and memory is released properly
• 📦 ASEG-GDF2 export/import improvements: channel naming behavior improved; Date channel formatting corrected to support accurate calculations (e.g., IGRF)
• 🧲 IGRF tool fix: correct output when a constant is used for the elevation parameter
• 🗂️ UX-Analyze: importing large HDF datasets no longer freezes; progress indicator and better logging added
• 🌊 UXO Marine: heading interpolation wrap-around (0°/360°) handled correctly to prevent circular line paths

Result: fewer interruptions, better big-data performance, and smoother map/database workflows for production projects. 📈✅
