Hi,every one. I am working on geostatistics with arc GIS and facing one very basic strange problem.I am doing ordinary kriging through geostatistical wizard of ArcGIS using the data set(excel file) i attached in this post.This is the process i did
1)added data through "add XY data " under file tab . then changed its coordinate system(the excel file contains lat,lon which refer to GCS).so I projected it onto UTM coordinate system.
2)Then exported the data to file "export_output".After that using geostatistical wizard i performed the ordinary kriging.I checked variogram for both projected and unprojected.
Data Type: Shapefile Feature Class
Shapefile: C:\Users\IIT\Desktop\arcgis\Export_Output_2.shp
Geometry Type: Point
Projected Coordinate System: NAD_1983_NSRS2007_UTM_Zone_14N
Projection: Transverse_Mercator
False_Easting: 500000.00000000
False_Northing: 0.00000000
Central_Meridian: -99.00000000
Scale_Factor: 0.99960000
Latitude_Of_Origin: 0.00000000
Linear Unit: Meter
Geographic Coordinate System: GCS_NAD_1983_NSRS2007
Datum: D_NAD_1983_NSRS2007
Prime Meridian: Greenwich
Angular Unit: Degree
and this is the wierd variogram plot i'm getting
[ATTACH=CONFIG]34369[/ATTACH]
The below is the variogram for GCS COORDINATE SYSTEM
[ATTACH=CONFIG]34373[/ATTACH]
The main issue is that the variogram plot should be till half the maximum distance.Here the x axis is supposed to be h*10^-5 but it is showing 10^-1.( This data set has a max distance of 1000 kms. so when projected onto UTM ,the variogram X axis should be h*10^-5.But it isnt.) I dont understand why. please some one suggest me the mistakes or is it my installation problem
