In ArcGIS Pro, you can do this work quickly and automatically with ModelBuilder and the ToolBox, which you can develop specifically for your workflow. These tools, which you can develop according to your workflow and ne!s, r!uce the ne! for re-processing for each drilling project and minimize the risk of errors.
Chapter 2. Lithology Model and Block Model with ArcGIS Pro
With ArcGIS Pro, you can create a block model in 2 steps with the lithological and mineralization data you have.
In this section of the blog post, we will explore the lithology below the surface using the drilling data containing lithology information that we creat! in the previous section and we will transform this lithology into a 3D model. The drilling data we had was classifi! according to lithology information and three lithology information was color!. We will also use this classification in the symbology of the 3D model that we will obtain.
1. Interpolation of drilling data
In the first step, the borehole data is interpolat! using the Imperial Bayesian Kriging 3D tool. This provides a geostatistical interpolation that will fill the follow up on link!in gaps between boreholes by estimating the lithology they may have. After interpolation, the lithological features of the borehole can be seen by switching between the heights in the layer add! to the scene.
Merging lithology layers into voxel layers:
The data we creat! has a layer for each height, in the second step we will create a three-dimensional voxel layer by merging the layers at all heights. For this, how did you get start! in marketing and communications? we will use the GA Layer 3D to NetCDF tool. Thanks to this tool, the layers at each height of the drilling data containing lithology information are merg! and become a three-dimensional model. Here we can create blocks by determining the dimensions of the three-dimensional layer we will alb directory create in the x, y and z planes. In addition, while creating the layer, we can use the drilling points as an outer boundary, as well as a polygon that we will determine as a boundary, and determine the boundaries where the three-dimensional lithological model to be creat! will expand. At this point, topography can be us! as a height limitation.
