Process steps for creating Hotspot Density Map
Click Create Raster in the Interpolate group to display the interpolation methods and select Hotspot Density
The Create Raster dialog displays.
From the Input File drop-down list select the file or click to browse and select the required input data file. When the input file is open, from the Select Columns drop-down list, select one or more input data columns. It lists all the columns in the input file and allows you to select the column that contains input data points. The selected column will be used in the interpolation process.
Select Hotspot Density method from the Select Method drop-down list. You can now specify the required parameters (For more information on available parameters, refer to Hotspot Density Method Options).
In the Method Options, specify whether spatial parameters are defined in cell units or distance units. If you choose Distance, you need to select a distance unit from the Distance Unit drop-down list. Define search mode to provide information on input data points within the search neighborhood. A default search radius is calculated for you.
In the Raster Geometry section, specify the cell size and raster bounds for the output raster. If required, click More Options to specify category and sub category of the output projection. If the input file is MapInfo .TAB, projection values are read from the input file, which you can override here.
In the Output File box enter the name you want to specify for your output file. Click to browse to the location in your computer to save the output file and select the required output file format. The values in Output Settings are controlled by the Raster Preferences dialog; however, you can override those settings here. Select the Display Output File check-box, if you want to open the output file in the Map window on completion of the operation. Click Process to start the hotspsot density method interpolation process. The task will then be added to the Task Manager where you can monitor the progress. On completion of the operation, the hotspsot density raster displays in the map window.
