Combining Multiple Raster Files - MapInfo_Pro_Advanced - 2023

To combine several raster files into one raster:

1. On the RASTER tab, in the Operations group, click Raster Operations and then click the Combine button to open the Combine dialog box.
2. In the Input File select files from the drop-down list or browse to a file location to select the required files.
3. From the Combine Inputs As drop-down list, select how you want to combine the multiple rasters. You have three options in the drop-down list to choose from.
   • Bands of a Single Field - If you select this option, the selected input rasters will be added as bands to a single field in the output file.

     

   • Individual Fields - If you select this option, the selected input rasters will be added as separate fields. The individual fields may have bands.
   • Custom Mapping - Select this option to combine single-field legacy rasters and create a multi-band MRR raster.
4. In the Output Raster Structure section, you can determine the field and band structure in the output raster. You can add or delete a filed/band. For example, you can delete a field or band by clicking on the button. The list is dynamically updated as you add or remove a field or band.
5. 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 data speed and space. 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.
6. Click Process to start combining the selected raster files.
