The Resample dialog box enables you to create a new grid with new cell dimensions based on an interpolation method.

Input

  • Create MVR - Select the check-box to create the output in the Virtual Raster format.
  • Batch Mode - Select the check-box to process multiple inputs with the same set of input parameters in a single go. Batch mode also supports single field single band conversion for supported files.
  • Input File - Select the input raster dataset that you wan to resample. Click the folder icon in this section to select a grid from your computer.
  • Select Fields, Bands - If the selected input raster has multiple fields and bands, the Select Fields, Bands option allows you to choose either All Fields All Bands or a particular field for the processing.

    Select a specific field from the drop-down list, you can then choose the desired bands from that field. 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.

The following figure represents an example raster that will be resampled.



Resample Options

The Resample Options section consists of the following:

  • Resample Method - This drop-down list contains the interpolation methods used to resample the input grid. There are three resample methods in MapInfo Pro Advanced. See Resample Methods for more details. In this example, you will see how the input raster has been resampled using the three available methods. All three grids have a new cell size of 3x3.
    1. Nearest

    2. Bilinear

    3. Bicubic

  • Current Cell Size - Defines the existing cell size of the input raster grid.
  • New Cell Size - Denotes the new cell width or height for the interpolated cells. The height and width are the same because MapInfo Pro Advanced can only use square grid cells.

Click More Options to check the following information.

  • Old Dimensions - Displays the original raster size in width and height.
  • New Dimensions - Displays the new raster size in width and height. This value is calculated based on the New Cell Size value.

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.
    For more information, see Encoding Type.
