MapInfo Pro Advanced supports a wide variety of interpolation methods to create surface raster from point data.
Input File
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 Selecting Input Data for Interpolation.
Group - If you have huge dataset but you wish to perform interpolation for selected
data only, you can use the data conditioning and grouping options by clicking 
button. MapInfo Pro Advanced allows you to filter your input data before executing the
interpolation. Data conditioning and grouping are pre-processing operations on the input
data prior to gridding. For more information, see Filtering Input Data for Interpolation.
Interpolation Method
Select Method
This drop-down list contains the interpolation methods used to create the raster. Select one of the interpolation methods from the list.
MapInfo Pro Advanced supports the following interpolation methods. Click the links below to know more about the supported methods and their properties.
Parameter Units- Select either cell units or distance units as spatial parameters.
Method Options
The Method Options vary according to the selected Interpolation Method.
More Options
The More Options button appears depending on the interpolation method selected. Expand More Options to set the advanced parameters for the selected interpolation method.
Raster Geometry
In the Raster Geometry section, specify the cell size and raster bounds for the output raster. For more information, see Defining Raster Geometry.
More Options
By default, the output data will have the same projection as the input data. However, you can reproject the data in the output file by selecting the desired projection system from the Category and the Sub Category drop-down list.
The Category drop-down list consists of all projection systems supported by MapInfo Pro. For example, Longitude/Latitude, Universal Transverse Mercator (ED 50), Universal Transverse Mercator (NAD 27 for Canada), etc. The Sub Category drop-down list consists of the type of projection based on the selected projection system.
Output File
Specify a name, location and format for the output raster that you are creating. 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. You can also select the required output file
format.
Click Output Settings to specify the following. The values in Output Settings are controlled by the Raster Preferences dialog; however, you can override those settings here.
Display Output File - Select the check-box, if you want to open the output file in the Map window on completion of the operation. You can configure to make this the default behavior from the Raster Preferences dialog.
If the output file format is an MRR or a TIFF, additional options appear. The available options are listed below.
- Compression Settings
- Data Balanced
- Data Speed
- Data Space
- Advanced
The Data Balanced option allows you to achieve a balance between speed of operation and file size. The system selects the best combination of speed and space for you. With the other two options Data Speed and Data Space, you can choose between speed of operation and storage space. Choose Advanced option to set the advanced compression settings such as compression method, level, and encoding type. For details on the Advanced option, see Compression Settings.
- Compression- Select a suitable compression method and level for the data. For more information on compression, see Compression methods.
- Encoding Type - Select a suitable Encoding Type for the data from the list. It enables you to compress the data when saving a raster to MRR format. Encoding Type is enabled only when the raster field type is Continuous and the compression method is lossless such as ZIP, LZMA or LZ4. The drop-down list contains the following:
- None - No encoding.
- Previous Column Linear - Performs linear estimation of the value from previous two columns.
- Previous Column Value - Predicts the value from previous column.
