Input File
Select an input raster from the drop-down list or browse to a file location to open the input raster. Then click the drop-down list and select the check box against the raster.
If a file is already open on the Map window, you can quickly create heatmap using one of the methods.
Interpolation Method
At any point of analysis, you can select other Heatmap methods from this dialog.
- Weighted Estimate - For detail about this method, see Weighted Estimate.
- Sample Count - For more detail, see Sample Count.
- Sample Density - For more detail, see Sample Density.
- Advanced - For more detail, see Advanced.
Method Options
- drawing a polygon on the map.
- specifying a .TAB file containing a single or multiple polygon objects.
- None - Denotes no clipping, and nothing is selected on the map.
- Polygon - Click this option to either select a TAB file containing a single or multiple polygon objects, or draw a polygon on the map window. When you draw a polygon on the map, MapInfo Pro creates a temporary new selection table. The Selection appears in the clipping drop-down list and it contains the area that falls within the drawn polygon.
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.
Raster Geometry
In the Raster Geometry section, specify the cell size for the output raster in the Cell Size box.
The cell size defines the width and height of a raster cell in distance units. If the raster cells are square both width and height are specified with same value.
By default, Automatic is selected which means will calculate the output raster cell size based on source data points. You can modify the cell size value to produce output raster with the desired cell size.
Output File
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 .MRR file.
