Geosoft's Oasis montaj is powerful processing and mapping software for mineral exploration, oil and gas exploration, and earth science investigations including environmental projects and Unexploded Ordnance (UXO) detection.
Using montaj, geoscientists can efficiently import, view, process, and share earth science datasets, grids and images within one integrated environment.

The Oasis montaj software package includes a rich set of built-in data import, processing, visualization, mapping, and integration capabilities. It features Geosoft's complete library of basic and advanced gridding utilities, and plotting functionality.

A variety of montaj extensions and montaj plus extensions are available for advanced geophysics and geochemical data processing, analysis, quality control and modeling, making Oasis montaj one of the most robust and comprehensive geoscience mapping and processing systems in the world.

The Geosoft montaj viewer enables easy sharing of Geosoft data within your company, and the larger geoscience community. Software plug-ins are available for ER Mapper and MapInfo, providing superior connectivity between your montaj mapping software and your GIS or specialized applications.

Key Features

Oasis montaj provides these key mapping and processing features:

High-performance database
Oasis montaj’s high-performance database provides efficient storage for very large geoscientifc data sets. Database support is provided for up to 2 billion data points per channel. Data can be accessed directly through a spreadsheet window and an integrated profile display window.

Data processing
The montaj processing engine enables users to run numerous filters and processes on their data. Rapidly assess and experiment with data in real-time. Easily combine data and have multiple profile windows open for comparison with maps. Work with collections of data points or treat individual points.

On-the-fly projection
Geosoft’s advanced projection engine provides on-the-fly projection. It can handle over 2000 datums and projections.

Dynamic linking
Oasis montaj enables users to dynamically interact with data and evaluate results throughout their project lifecycle. Edit maps interactively, apply dynamic linking to multiple views of imagery, maps, profiles, data and metadata, and track map creation processes, all within one mapping environment.

Advanced gridding
Oasis montaj’s gridding algorithms are fast, efficient and optimized for large-volume geoscientific data. Interpolate data and produce grids using these Geosoft gridding routines: Minimum Curvature, Bi-Directional, Trended, Gradient, Tinning and Kriging. Enhance and manipulate grids using a variety of grid processing tools and advanced grid utilities.

Professional map production
The software provides a full featured dynamic contouring algorithm with gradient feathering and extensive labeling control for professional quality presentation results. Quickly create multiple and varied types of maps, including gridded maps, surface maps, posted value maps, and sub-location maps.

3D Visualization
Oasis montaj provides a range of options for visualizing data in three dimensions. Display multiple surfaces, each with own relief and contents, and each with its own orientation in 3D space. Drape a coloured grid or image file over a topographic surface or digital elevation model (DEM) grid. The 3D technology also enables you to display any Geosoft map aggregate, which may contain a number of images, symbols and interpretation features over a topographic surface grid.

Data sharing with GIS and specialized applications
A number of plug-ins and data conversion options provide superior connectivity between your montaj mapping software, and your GIS or specialized modeling applications. Software plug-ins are available for ER Mapper and MapInfo. The freely available Geosoft montaj Viewer provides a wide variety of grid format conversions, ensuring compatibility with leading GIS and specialized applications, including mine modeling and environmental software.

Oasis montaj also includes a Geosoft DAP client which enables users to search and retrieve geoscientific datasets, imagery and other map data directly form a DAP server on a local network or on the Internet.
