Import Geosoft Grids

Summary

Imports one or more Geosoft grids (.grd) into raster datasets in a geodatabase. This tool can be used to import multiple Geosoft grids into separate raster datasets. Section oriented grids can also be imported so that they appear in their correct locations in 3D scenes.

Usage

During the import, the Geosoft grid is converted to an Esri raster dataset: the new raster dataset, identical to the input grid (which remains unchanged), is created in the selected geodatabase.

You can select a single grid, or several grids to import. If several grids are imported, the new raster datasets will all be created in the selected geodatabase and will all have the same spatial reference.

The output raster dataset will acquire the input grid's coordinate system, if one was defined in the input grid. Note that the coordinate system information is stored in a GI file (.gi) that accompanies a Geosoft grid; a grid's GI file shares the same file name as the grid. Learn more about grids and coordinate systems in About Geosoft Grids.

Parameters

Parameter	Explanation	Data Type
Geosoft Grids	The input Geosoft grid file(s) to import. See the Technical Notes section below for more details on importing section oriented grids.	Geosoft raster grid (.grd) file
Overwrite existing datasets	If any of the Geosoft grids to be imported already exist in the output geodatabase, this determines if they will be overwritten, or not: Checked - The existing raster dataset(s) will be overwritten Unchecked - The existing raster dataset(s) will not be overwritten
Add layers to current map	This determines if the incoming rasters will be displayed into the current map or scene window: Checked - The imported raster(s) will be displayed in the current map or scene. Unchecked - The imported raster(s) will not be displayed in the current map or scene.
Output Geodatabase	The output geodatabase in which to store the new raster dataset(s).	File Geodatabase

Technical Notes:

Converting section oriented grids:

When converting section oriented grids (i.e. vertical or inclined rasters) that have been "oriented" in a Geosoft software, the 3D location and orientation will be maintained during the import, provided the GI file is present.
On conversion, a feature class is created to store the position and orientation of the vertical or inclined raster so that the section will appear at the correct spatial location in 3D. The feature class contains the outline of the section raster location, while the raster dataset created (and denoted by a "_RasterData" suffix) will contain the image of the original raster data.
- If the active map in Target for ArcGIS Pro is a 3D scene, the section raster datasets will appear at their correct locations and orientations in the scene.
- If the active pane is a map window, section oriented rasters will appear as a polygon outline of the raster locations only. To view sections correctly, add them to a 3D scene.
- If the raster dataset is added from Catalog without the multipatch feature class, the raster dataset will not appear in the correct location since this is relative to the section orientation and origin. By displaying the feature class together with the raster dataset, the original location, orientation and appearance of the section raster is maintained.
