To apply the Estimate method:

  1. On the Raster tab, in the Interpolate group, click Create Raster to display the interpolation methods. Click Estimate from the Heatmap category. The Heatmap dialog displays.
    Note: The various interpolation methods are grouped into logical categories. There are categories for Heatmap, Assignment, and Interpolation. Each category has multiple interpolation methods under them. When you select any method from a category, the dialog box title displays the category name instead of selected interpolation method name.
  2. Click Select Files to open the Select Input File panel. Click to browse and select one or more input data files. For more information, see Select Input File.

    When you are done with file selection, click OK to exit Select Input File panel and return to the Heatmap dialog.

  3. (Optional) Click the Select Method drop-down list to change the selected method. The parameters specific to the selected method display on the dialog box.
  4. Click the Kernel drop-down list to select a Kernel function.

    The Quartic, Triweight and Tricube kernels produces smooth and nice Heatmap. If you want to increase the search radius but retain a high level of detail, you should use the Gaussian kernel.

  5. Click the Clipping drop-down and select a clipping option to constrain interpolation distance around source data points.
  6. Enter Search Radius in the box.

    The search radius controls the resolution of the Heatmap. Use a smaller radius, and small cell size, to reveal more details and higher resolution. Use a large search radius to generate a smoother Heatmap. The search radius also impacts the processing time of the calculation. Use a smaller search radius to reduce the processing time.

  7. Enter a Cell Size for the output raster.

    The raster cell size will limit the amount of spatial detail that can be recorded in the Heatmap. Use a small cell size to ensure detailed information is retained. Also, the cell size impacts the processing time of the calculation. Use a larger cell size to reduce the processing time.

  8. Enter the output file name in the box. Click to open the Save File As dialog. Browse to select the output file directory in your computer. The Heatmap outputs only an MRR file.
  9. Click Process to start the raster interpolation process. The task will then be added to the Task Manager where you can monitor the progress. On completion of the operation, if you have selected Display output file check-box in Output Settings, the output raster displays in the map window.
