Input File
Select an input raster from the drop-down list or browse to a location in the computer to select the file.
Classify Options
The Classify Options section contains the following options.
- Output raster type - You can select the output raster type by clicking either Numeric or Classified. If you select Numeric, you can change the existing value of a class. If you select Classified, you can change the name of a class and assign it a new name.
- Class Interval Type - You can change the Interval range by clicking either Continuous or Discrete. If you select Continuous, the interval range is continuous which means if you change the value in one class, the values in other classes get updated. If you select Discrete, you can change the value and enter desired value for the range. the values in other classes do not gets updated.
- Derive Class Colors from - This drop-down list contains all color look up tables (LUT files) which you can select and assign colors to each cell ranges.
- Load - Click this to upload an existing classify profile.
- Save As - Click this to save a classify profile into a text file.
- Intervals - This dialog box displays the input classification range
and the number of classifications or bins in the output raster. Each class is
assigned a color which you can change according to your requirements.
- Minimum - Minimum cell value of the input grid.
- Maximum - Maximum cell value of the input grid.
- Method - Determines whether to change the classification according to cell value or number of bins. You have two options Number of Intervals and Interval Spacing. If you select Number of Intervals, the intervals are divided equally, according to the number specified in the Value field. If you select Interval Spacing, the intervals are spaced, according to the number in the Value field.
- Value - Defines the number of intervals or spacing between interval values on the basis of which the raster will be classified.
- Use Null for Undefined Class - Select this check-box to use null values in the output raster for undefined class intervals. Clear this check-box to specify undefined classes. You need to enter Undefined Class Value, Undefined Class Label and pick a Undefined Class Color from the drop-down list.
- Insert Row and Delete Row - Click to add and delete a class respectively.
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.
