It’s a new month! 2011 is turning out to be a good one. Today we would like to show the Irrigation Designer how to obtain the heights of nodes from the underlying DTM .
In Irrimaker the irrigation node interpolates its elevation when initially placed on a DTM model. If the model is not available, the node elevation will be zero. When you later on place a DTM model underneath the irrigation design, the program is not automatically going to change the elevations. The Automatic Elevation function must be used for that.
You might have STARTED your irrigation without a DTM survey model and all the nodes ended up on a zero elevation. When a DTM is later available and you want to set all the irrigation nodes to the correct value, follow these steps:
To get the heights from the ground model and apply it to the nodes you should use the Automatic Elevation option.
Without checking the box, only the current block will be interpolated. Checking the box will re-evaluate all the blocks.
After completing the procedure, you will notice the nodes all have correct heights obtained from the DTM ground model.
We suggest using Irrigation Software intelligently and believe you will benefit from this quick tip. If you have any questions or suggestions please feel free to let us know in the comments bellow.
Thank you for your time and attention.
