-Creating consistent 3D images of geophysical and geological datasets and turning that into an input model for geodynamic simulations is often challenging. The aim of this package is to help with this, by providing a number of routines to easily import data and create a consistent 3D visualisation from it in the VTK-toolkit format, which can for example be viewed with [Paraview](https://www.paraview.org). In addition, we provide a range of tools that helps to generate input models to perform geodynamic simulations and import the results of such simulations back into julia.

 All data is transformed into either a `GeoData` or a `UTMData`  structure which contains info about `longitude/latitude/depth`, `ew/ns/depth` coordinates along with an arbitrary number of scalar/vector datasets, respectively. All data can be exported to Paraview with the `Write_Paraview` routine, which transfers the data to a `ParaviewData` structure (that contains Cartesian Earth-Centered-Earth-Fixed (ECEF) `x/y/z` coordinates, used for plotting)

 ## Visualising Alpine data
-We have used this package to interpret various data sets of the Alps (mostly openly available, sometimes derived from published papers). You can download the resulting paraview files here (using the `*.vts` format), where we also included the julia scripts to do the work (some of which are also described in more detail in the tutorials). Just unzip the files and open the corresponding `*.vts` in Paraview.
