Thanks a lot. Yes, I find the the range of geostatistical layer is different from the raster one. So now I am thinking if I can set the range of geostatistiacal layer. What I mean is that I got the geostatistiacal layers, and I will set the range of these geostatistiacal layers, for example the minimum is 0, then I can use GA Layer To Points tool to get the values  of the points, which supposed to be larger than 0. ...

Hi, Erik I have another question for Kringing Geostatistical Wizard. Can I set the lower and upper values for the results of Kriging interpolation? Thanks! ... View more

Thanks a lot. I download Version 10.3 and I solved the problem. ... View more

Hello, here, we can do the loop? I mean I can chang dataset1 every time, then do the interpolation for the different dataset1? ga_layer = r"c:\temp\kriging.lyr"  geo_datasets = arcpy.GeostatisticalDatasets(ga_layer)  print geo_datasets  >>dataset1='c:\temp\myfc.shp' dataset1 Field='ELEVATION' ...

Hello, I am reading these information, which are really useful for me. According to your discussion. I already can do the kriging using python for a given shpfile. I don't know how to do the loop. What you use for the loop. As here we can not use iterators from model bulider.  Thanks a lot!!!! ... View more

Hi, I am reading these information, which is very useful for me. But I am using version 10. There is no arcpy.GeostatisticalDatasets in version 10, right? What I should do for these general workflow: newDataset = arcpy.GeostatisticalDatasets("C:\\temp\\myXML.xml")  newDataset.dataset1 = "C:\\temp\\myFeatureClass1.shp"  newDataset.dataset1Field = "myField1"  arcpy.GACreateGeostatisticalLayer_ga("C:\\temp\\myXML.xml", newDataset, "outGALayer1") Thanks very much!!!! ...

Hi, When I use the Geostatistical Wizard, I set some parameters, which confused me a lot. In step 2, the order of trend removal. my data include precipitation data from several years. In Some months, the data has trends, but in some data, there is no trends. When I do the interpolation, for these data, I should use the some criteria. I mean for all the data, I should choose the some parameters. Here, should I choose to remove the trend? If so, it will influence the data which don't have any trend. In step 3, General Properties, there is Kerenel Function, which is a local polynomial and is a qick interpolator. And in step 4, we have semivariogran model which is also a interpolator. Can anyone tell me difference between them. Thanks a lot! ... View more

Thanks a lot. To create the template layer is to use the Geostatistical Wizard. In the Wizard, you can specify the interpolation parameters for the template layer. With ArcGIS 10, you can even use the Wizard to optimize various interpolation parameters. 1. Now if I am using Geostatistical Wizard to create a template layer, and I use optimize various interpolation parameters. Then I use this template layer as model resource to create a geostatistical layer for the measurements of the new day. These optimize various interpolation parameters also works for the measurements of the new day. 2. In Geostatistical Wizard, you optimize various interpolation parameters for the variance and semivariogram. What is the difference, and how do I know which one should be chosen. ... View more

Hi, I want to know if Python class GeostatisticalDatasets​also existed in version 10. Thank you! ... View more

Thanks a lot. Here I have a question. How can I apply the geostatistical layer which created by Create Geostatistical Layer to the measurements of the new day? ... View more

Hi, Eric When I read your post, I am confused about these two layers, what is the difference between two layers: the existing geostatistical layer and the new one, which we create using the Create Geostatistical Layer tool. I mean we already created on using Geostatistical Wizard, why we need to use Create Geostatistical Layer tool to create a new one. Thank you. ... View more
