Datasource: Select the Datasource where the Dataset to be interpolated is located.

Dataset: Select the Dataset to interpolate. The system automatically filters the Dataset under the selected Datasource according to the interpolated Data Type, and only displays the Point Dataset under the Datasource.

Interpolation field: Select the relevant field to be interpolated and automatically filter it as a numeric field. This field is an Elevation Field if the interpolation is to predict the elevation, a precipitation related field if the interpolation is to predict the precipitation, and a noise decibel field if the interpolation is to predict the noise level. Therefore, before analysis, the selected Point Dataset must have relevant fields.

Scale: The scale ratio of the interpolation field value. The value for Interpolation Analysis can be scaled by multiplying the interpolation field value of the source data by the Scale Factor and then interpolating. As shown in the figure below, the Scale Factor in the left figure is 1, and the Scale Factor in the right figure is set to 2. After interpolation, the grid value at the same position is about twice that of the left figure.

Datasource: Select the Datasource to save the Spline Interpolation Analysis results.

Dataset: Enter the Dataset Name for Interpolation Analysis results to be saved. If the entered Dataset Name already exists, you will be prompted with Invalid dataset name and need to re-enter it.

Resolution: Enter the resolution of the Interpolation Analysis result, that is, the size of the ground area corresponding to a single pixel, and the unit is consistent with the Dataset unit. You can enter the resolution directly, and then the system will automatically calculate the number of rows and columns based on the entered resolution.

Pixel Format: Storage format of interpolated Dataset pixels, including 1-bit unsigned, 16-bit, 32-bit, Single, Double. Users can select the appropriate Pixel Format according to their actual needs. Please refer to the Raster DatasetPixel Format for the specific description of Pixel Format.

Columns: indicates the number of columns of the grid calculated by Grid Bounds and cell height (or cell latitude difference).

Rows: indicates the number of rows in the grid calculated by Grid Bounds and cell width (or cell offset).

Bounds defaults to Dataset Bounds, and SuperMap provides the following three settings:

• Dataset Bounds: Click to select the Dataset Bounds "radio box to set Dataset Bounds to Analysis Bounds.
• The right Drop-down Button provides the following two methods:
  • Select Object: Select one or more objects in the current Map through the mouse box or click mode, and Select ObjectsRange Settings as Export Bounds;
  • Draw Bounds: In the current Map, click Draw to determine a rectangular area as Export Bounds;
• Copy and Paste: Click the Copy button to Copy the range of the Current setting. Click the Paste button in the Range Settings that supports pasting to set the left, bottom, right, and top values of the Copy Bounds to the current range.

• Click the Environment Settings button to set the Analysis Environment parameters. The Analysis Environment parameters supported by Interpolation Analysis include the Geographic Range, Clip Bounds, and Default Cell Size of the Result Dataset. Please refer to the Set up the Analysis Environment page for detailed description.

  Note: The environment parameter Set As Global is supported, that is, the parameter value set here is used as the total Raster Environment Analyst environment parameter. Other functions that support the environment Parameter Settings are not required to be set repeatedly. If an environment parameter is not set here, the setting of the parameter in the Raster Analysis Environment is read during analysis.
