This tool produces a triangular irregular network from a point layer to visualize elevation or stepped heat visualizations. It can be used to represent surfaces or terrains where every vertex (point) is connected to form a network of triangles.
- This tool can be implemented on point layers only.
- Layer must contain integer data attributes such as elevation in meters, atmospheric pressure or temperature.
The Tin tool can be selected by navigating the following path:
Tools > Vector Processing > Spatial Analysis > Tin
The first section requires you to select required data layers to run the Tin tool.
The second section requires you to select the range of data for the operation to be implemented. There are three options available:
- Select By Data Queries
- Select By Graphics
- All Data
For more information about these options and how to implement them, see Data Selection Methods.
The output polygon consists of interconnected vertices forming a triangular network representing the terrain of the input layer.
You can view the output after storing it. To save the output, you must enter the Output Layer Name and click on Save Data button. The saved output will be added as a new layer in the current map session, where you can apply styling as required. This output layer will also be available in 'My Data' section and can be used in any map session of interest.
