Welcome to the Leapfrog tutorial for beginners. In this article, I am going to share my experience with Leapfrog. Leapfrog is a great tool to create a 3D geological model. There are many types of data that we can bring into Leapfrog Geo, for example, an image map. We will learn how to georeference a geological map in Leapfrog. You can download the resource files that I used in this article using the link below.
How to Georeference a Map in Leapfrog Geo
First, we need to create a project. We will start a new empty project for this purpose. And then, right-click GIS Data, Maps, and Photo and choose Import Map. Choose the file Sagean Valley Map.png from the resource files you’ve downloaded above. And then, you should see something like this one below.
There are three control points needed in order to georeference a map in Leapfrog Geo. Move the points by dragging the rectangle, circle, and diamond symbol as shown above. And then, type the coordinate for each control point. When done, click the Import button on the top bar. Now you should see the new map under GIS Data, Maps, and Photos.
Create Topography from a Mesh
The next step is to create Topography from a Mesh. To import a Mesh, right-click the Meshes and then Import Mesh. Choose the Topo.dxf file in the data package. Next, right-click Topography and select New Topography >> From Surface.
Click OK to complete the process.
Display the Map in 3D
To display the geological map in 3D, drag the Topography to the Leapfrog scene. On the layer list, under the Topography, click GIS Data and then choose Map and Photos and then select the Sagean Valley Map.
Building a geological model is a long process. We can start with this very simple task. Importing a map into Leapfrog Geo is not complicated. We can also import a georeferenced image from other software as well. Thanks for reading this article and see you on the next tutorials.
