Using GeoTIFF files in RockWorks:

The GeoTIFF import is really designed to import DEMs saved as GeoTIFFs, and not images.

If you want to display the image in RockPlot2D, you can import it through the File | Import | Raster Image menu.  You can use the world file to georeference the image, as long as the coordinate system is the same (the program does not read the PRJ file).

If you want to drape the image over the RwGrd file, the Image | Drape program allows you to select the image and world file, along with the RwGrd file.

New programs titled “Grid Evaluation” and “Solid Evaluation” have been added to RockWorks.

Use these programs for quantifying the “goodness-of-fit” for an interpolated grid or solid model. The Evaluation programs generate a report with diagrams that depict the accuracy of a grid or solid model relative to the original control points used to interpolate the grid or solid values.

New Grid Model Option Added

An option titled “>2 Grids” has been added to the 40 RockWorks programs that create profiles, sections, and projected sections. This new feature can be used to overlay an infinite number of labeled and/or symbolled profiles based on grid models listed within the datasheet.

New ModOps, Contours → Grid program

The Contours → Grid program will convert the polyline data within a RwDat or a Rw2D file into a grid
model constructing a triangle network between the vertices of the polylines and estimating the
elevations of the grid nodes that reside within these triangles. Found in the >ModOps >Grid >Create menu.
