In some cases, you will need to define a topography on your Leapfrog project. Even it is not mandatory, defining a topography in Leapfrog is very useful. Topography can be used as the upper boundary of a geological model. In this tutorial, I am going to show you how to create topography from an elevation grid in Leapfrog Geo.
Basically, Leapfrog supports various sources to build the topography. You can use the elevation grid, points data as well as GIS data. But in this article, I will specifically show you how to build the topography from the elevation grid.
Topography from Elevation Grid
There are two ways to create topography from an elevation grid.
- Right-click the Topography folder and select New Topography >> Import Elevation Grid. Browse the elevation grid file and then choose OK. Read how to create a surface elevation grid in Surfer.
- Browse and select your grid file. Leapfrog supports various gird file-formats including asc, dem, grd, img, tif.
- Specify the surface resolution. The smaller resolution will give you a better or smoother look. But it will take more processing times.
- You can also set the clipping boundary and don’t forget to give a name for the new topography.
5. After import, you will see the newly imported grid is listed under the Meshes. To open the new topography, simply drag the topography file.
