Create Geostatistical Layer

Creates a new geostatistical layer. An existing geostatistical layer or geostatistical model is required to populate the initial values for the new layer. The input to this tool can be created using the Geostatistical Wizard.

1.    Input geostatistical model source

The geostatistical model source to be analyzed.

2.    Input dataset(s)

The name of the input datasets and field names used in the creation of the output layer.

When checked, the Always reset input datasets when the geostatistical model source changes parameter ensures that when a different geostatistical model source is specified, its associated datasets are automatically inserted into the tool.

If unchecked and the geostatistical model source is changed, the displayed input datasets remain unchanged. This can lead to problems if the model is incompatible with the dataset; for example, a model was created to predict temperature, and a new dataset with rainfall data is specified.

3.    Output geostatistical layer

The geostatistical layer produced by the tool.Output geostatistical layer The geostatistical layer produced by the tool.

GA Layer to Contour

Creates a feature class of contours from a geostatistical layer. The output feature class can be either a line feature class of contour lines or a polygon feature class of filled contours.

1.    Input geostatistical layer

The geostatistical layer to be analyzed.

2.    Contour type

Type of contour to represent the geostatistical layer.

  1. CONTOUR— The contour or isoline representation of the geostatistical layer. Displays the lines in either draft or presentation quality.
  2. FILLED_CONTOUR—The polygon representation of the geostatistical layer. It assumes for the graphical display that the values between contour lines are the same for all locations within the polygon. Displays the lines in either draft or presentation quality.
  3. SAME_AS_LAYER—Use the current renderer of the input geostatistical layer. If the geostatistical layer is not rendered as either contour or filled contour, this option will created filled contours. Similarly, if the geostatistical layer is rendered as both contour and filled contour, this option will create filled contours.

3.    Output feature class

The output feature class will either be a polyline or a polygon, depending on the selected contour type.

4.    Contour quality (optional)

Determines the smoothness of contour line representation.

  1. DRAFT— The default Draft quality presents a generalized version of isolines for faster display.
  2. PRESENTATION—The Presentation option ensures more detailed isolines for the output feature class.

5.    Classification type (optional)

Specifies how the contour breaks will be calculated.

  1. GEOMETRIC_INTERVAL—Contour breaks are calculated based on geometric intervals.
  2. EQUAL_INTERVAL—Contour breaks are calculated based on equal intervals.
  3. QUANTILE—Contour breaks are calculated from quantiles of the input data.
  4. MANUAL—Specify your own break values.

6.    Number of classes (optional)

Specify the number of classes in the output feature class.

If Contour type is set to output filled contour polygons, the number of polygons created will equal the value specified in this parameter. If it is set to output contour polylines, the number of polylines will be one less than the value specified in this parameter (because N class intervals define N-1 contour break values).

This parameter does not apply if the Classification type is set to Manual.

7.    Class breaks (optional)

The list of break values if the Classification type is set to Manual.

  1. For contour output, these are the values of the contour lines.
  2. For filled contour, these are the upper limits of each class interval. Note that if the largest break value is less than the maximum of the geostatistical layer, the output feature class will not fill up the entire rectangular extent; all locations with predicted values above the largest break will not receive filled contours.

GA Layer to Grid

Exports a Geostatistical layer to a raster.

1.    Input geostatistical layer

The geostatistical layer to be analyzed.

2.    Output surface raster

The raster to be created.

3.    Output cell size (optional)

The cell size at which the output raster will be created.

This value can be explicitly set under Raster Analysis from the Environment Settings.

If not set, it is the shorter of the width or the height of the extent of the input point features, in the input spatial reference, divided by 250.

4.    Number of points in the cell (horizontal) (optional)

The number of predictions for each cell in the horizontal direction for block interpolation.

5.    Number of points in the cell (vertical) (optional)

The number of predictions for each cell in the vertical direction for block interpolation.

The geostatistical layer to be analyzed.

2.    Input point observation locations

Point locations where predictions or validations will be performed.

3.    Field to validate on (optional)

4.    Output statistics at point locations

The output feature class containing either the predictions or the predictions and the validation results.

The fields in this feature class can include the following fields (where applicable):

  1. Source_ID (Source ID)—The object ID of the source feature in the Input point observation locations.

  • The feature or object identifier of the input dataset that was used.
 Included (Included)—Indicates whether a prediction was calculated for this feature. The values in this field can be one of the following:

  • Yes—There are no problems making a prediction at this point.
  • Not enough neighbors—There are not enough neighbors to make a prediction.
  • Weight parameter is too small—The weight parameter is too small.
  • Overfilling—Overflow of floating-point calculations.
  • Problem with data transformation—The value to be transformed is outside of the supported range for the selected transformation (only in kriging).
  1. Predicted (Predicted)—The prediction value at this location.
  2. Error (Error)—The predicted value minus the value in the validation field.
  3. StdError (Standard Error)—The kriging standard error.

  5. NormValue (Normal Value)—The normal distribution value (x-axis) that corresponds to the standardized prediction errors (y-axis) in the normal QQplot.

5.    Append all fields from input features (optional)
