*

ArcGIS

MXD files), tools (3D Tool and Project Explorer) and Geosoft tool bars
(Database Tools, Map Layout, Map Tools, and Standard)

•

Evaluate data, information and interpretations by viewing and performing
specific tasks using Geosoft databases, profiles, maps, and grids as well as
Geosoft and third-party images (including Geosoft PLT, AutoCAD DXF,
MapInfo TAB, ArcView SHP, ArcGIS LYR, and Microstation DGN files)

•

Verify data quality, analyses and interpretations by tracking processes applied to
databases and maps

•

Perform selected processes made available through Geosoft menus or third-party
GXs

•

Share results and knowledge by viewing and/or sending E-maps and 3D PDF
files (see the Export To PDF 3D for more details) to team members and other
professional contacts

•

Prepare reports by exporting to 3D PDF or using clipboard image copying
capabilities

To access ArcGIS MXD files in

Oasis montaj

requires ArcMap or ArcEngine to

be installed on your computer.

The

Oasis montaj

environment provides direct access to data contained in Oasis

databases through a spreadsheet window and an integrated profile display window. The
Oasis database is a high-performance database that provides efficient storage and access
for very large spatial data sets.

The

Viewer

provides visual data links that enable you to dynamically connect data in the

spreadsheet, profile and map views. DAT technology (for accessing grids and images)
enables the

Viewer

to display a variety of grid and image formats in

Oasis montaj

.
