Resampling a Raster - MapInfo_Pro_Advanced - 2023

To resample a raster:

1. On the RASTER tab, in the Operations group, click Raster Operations and then click the Resample button to open the Resample dialog box.
2. Select the Create MVR check-box to create the output in the Virtual Raster format. It is generated quickly and occupies negligible space.
3. Select the Batch Mode check-box to process multiple inputs with the same set of input parameters in a single go.
4. Select the file to be resampled from the Input File drop-down list or click to browse the raster file(s).
5. Select a specific field from the Select Fields, Bands drop-down list, you can then choose the desired bands from that field.

   You can select multiple bands from any field, however, you can not select bands from different fields, because only one field can be selected at a time. Click the radio button against the field or check-box against the band that you want to select. By default All Fields All Bands option is selected for you.

6. Select the resampling method from the Resample Method drop-down list.

   You can choose from the three resampling methods listed - Nearest, Bilinear, or Bicubic.

   You can also see the cell size of the raster dataset in the Current Cell Size field.

7. Type the new cell size in the New Cell Size field.
8. Click More Options to see the old and new cell dimensions of the raster.
9. 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.
   1. 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.
      • Compression Settings - If the file format to be saved is an MRR or TIFF, the Compression Settings options will appear. The available options are listed below.
        • Data Balanced
        • Data Speed
        • Data Space
        • Advanced

          The Data Balanced 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 or space. Choose Advanced option to set the advanced compression options such as compression method, level, and encoding type. For details, on 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.
10. Click Process to start resampling the input raster dataset based on your selected resampling method.
