Yes, change the Gridder properties as follows:
- Select the Gridder module in the Network Manager.
- Click the General tab and set the Method to Inverse distance.
- Set the Power to 0.
- Click the Search tab.
- Change the Search type to Simple.
- Set the Min Count and Max Count to 1.
Using a power of 0 causes all distances to be treated the same, since n^0 = 1 where n is any number.
Setting the Search Max Count to 1 causes the Gridder to use only the closest data point.
