Hi All,
In my project I want to have isolines plotted at regular intervals (i.e. 100, 200, 300). In the specific set of data I’m using, the isolines fail to generate properly when using a Kriging style of interpolation.
Attached you will find a test project with the dataset in question. Simply run the program and click the Krig button. This will generate a map with isolines plotted using the min/max depth and 25 ClassBreaks so we get awkward intervals (59.375m). Next, select the Interval Isolines radio button and then Krig button again. This method creates intervals at 100m between the min/max depths. You will see the isolines fail to calculate properly and we only get a couple blips on the screen. The two images are shown below.
If you run using the IDW method, you don’t get the same behavior and isolines are more or less calculated over the limited area the search radius parameter allows.
Thanks,
Damian
