                                                       boolean deleteExistResultDataset)

        Performs a grid algebraic operation expression.

        Parameters:
        expression - A custom grid algebraic operation expression.
        extractRegion - User-specified valid calculation area. If it is null, calculate entire region. If the datasets are not inconformity, use the intersection to calculate.
        isZip - Whether to compress the result dataset. true means compression.
        ignoreNoValue - Whether to ignore the no-value grid data. true means ignore; otherwise, false.
        targetDatasource - The specified datasource that stores the result dataset. If set to null, the analysis will be stored in the input datasource.
        resultGridName - The specified result dataset.
        deleteExistResultDataset - Whether to delete the existing result dataset.
        Returns:
        The analysis result.

                                        boolean deleteExistResultDataset)

        Performs kernel density analysis on point dataset or line dataset. Return the result grid dataset.

        Parameters:
        inputParam - The parameters needed in kernel density analysis.
        sourceDatasetTag - The point or line datasets identification used to perform kernel density analysis (datasetName@datasourceName).
        fieldName - The field name of the measured value used to perform the density analysis. The density analysis doesn't support text field.
        targetDatasource - The specified datasource used for storing result dataset.
        resultGridName - The specified result dataset.
        deleteExistResultDataset - Whether to delete the existing result dataset.
        Returns:
        The result of kernel density analysis.
