Use the RASTER commands when working with raster files, which contain grid-based spatial information. The tab is also available in the Raster window when the window is floating. For a description of these commands, which are part of the MapInfo Pro Advanced raster extension, click the Help button on the RASTER tab.
After opening a raster file, such as a MRR, ERS, ASC, GRD, or GRC file, use the RASTER commands to apply processing, analysis, and creation operations to the raster data.
By default, all MapInfo Pro users have access to a subset of commands on the RASTER tab. To enable all of the commands on the RASTER tab, you must have a Advanced license. For a free trial of all of the raster features, on the Pro tab, click Licensing and then click Begin 30 Day Trial in the Advanced Version section. To purchase an Advanced license, contact your MapInfo Pro sales representative.

Open Workspace displays the Properties Group
These commands provide information about a raster.
| Icon | Command | Description |
|---|---|---|
 |
Raster Info | Opens the Raster Info window, which displays information about the raster dataset. |
 |
Statistics | Opens the Statistics window, which displays information about the raster dataset. By default, the Input File field is populated with the current raster file on display. Click Calculate Statistics in this window to generate information about the raster. |
 |
Cell Value | Queries and returns cell values from selected locations in a raster.
Full shows information about a selected location in the Cell Value window. Status Bar shows information about a selected location on the MapInfo Pro status bar, located at the bottom of the MapInfo Pro window. |
Interpolate Group
These commands let you select interpolation methods for creating continuous raster surfaces from point data. You must have an Advanced license to enable these commands.
| Icon | Command | Description |
|---|---|---|
 |
Create Raster | Creates a raster data set from vector data. |
 |
Create Raster Multifile | Creates a raster data set from multiple vector data files. Select from various interpolation methods to create continuous raster surfaces from the point data. |
Display Group
The following commands are active when you have a raster overlay on the map. These commands are also available on the STYLE tab.
| Icon | Command | Description |
|---|---|---|
 |
Field | Displays all the fields that are present in the active raster. To render different fields, select the field name from the drop-down list. There must be two or more fields to activate this command. |
 |
Display Mode | Select to render the file in either Pseudo, RGB, or Classified mode. You can render continuous and imagery file in either Pseudo or RGB display mode. |
 |
Band to Display | Displays all the bands for the selected field in the current raster, such as red, green, and blue. When in Pseudo display mode, select a specific band from the drop-down list to render it on the current map. When in RGB display mode, map different bands in the current raster to the RGB channel to then render it on the current map. This is useful for Landsat data. |
 |
Color | Opens a dialog to select the color to apply to the raster. The raster must be open in Pseudo mode to activate this command. |
 |
Color Stretch | Opens the Color Stretch dialog, which has options to enhance the display of a raster grid by changing the grid's appearance through data stretches. |
 |
Advanced Color | Opens a Color dialog to enhance all aspects of the appearance of the raster by changing its coloring, data stretches, and bandpass cutoffs. |
 |
Hill Shade | Opens a dialog of effects to mimic the sun's illumination, intensity, and shadows across variations in elevation within the map landscape (the raster surface). The raster must be open in Pseudo mode to activate this command. |
 |
Raster Quality | Improve the appearance of continuous raster surfaces using an interpolation technique when viewed at high resolution: None (this is the default), Nearest Neighbor, Bilinear, Cubic Spline (Local), or Cubic Spline (Global). |
 |
Favorite Template | Manage and apply custom templates. Selecting Manage Templates opens the Custom Templates window where you can create and edit your raster templates.
You must have an Advanced license to enable this command. |
Operations Group
Raster Operations Command
These commands process and analyze a raster overlay. A message dialog displays when a command requires an Advanced license to use it.
Processing
| Icon | Command | Description |
|---|---|---|
 |
Convert | Changes a raster to an MRR and other defined raster formats. |
 |
Clip | Cuts a raster to a rectangle object, a selected region object, or a table of region objects. |
 |
Combine | Arranges different input rasters into a single MRR file as individual fields or as multiple bands in a single field. |
 |
Resample | Creates a new version of the raster dataset wit a different height or width. |
 |
Merge | Combine multiple adjacent or overlapping rasters into a single output raster. |
 |
Reproject | Changes the projection of a raster dataset from one projection system to another. |
 |
Rasterize | Converts a vector file to a classified or numeric raster file. |
Analysis
| Icon | Command | Description |
|---|---|---|
 |
Point Inspection | Extracts all cell values from one or more input rasters at point locations and adds these as attributes of the points. |
 |
Calculator | Performs mathematical and logical operations on each cell in one or more input rasters. |
 |
Classify | Reassigns a value, range of values, or a list of values in a raster to new output values. |
 |
Surface | Calculates slope, aspect, and curvature from a continuous raster. |
 |
Region Statistics | Extracts aggregated statistics from a raster within region objects and add these as attributes. |
 |
Contour | Creates vector contour lines, polygons from a continuous, or polygons from a classified raster. |
 |
Cross Section | Extracts the cell values of a raster along a line or polyline. |
 |
Filter | Applies an enhancement or smoothing filer to a raster using a filter kernel. |
 |

About the Raster SDK for Developers
The MapInfo Pro Raster Software Development Kit (SDK) is the C#.NET based SDK to program next generation raster/grid technology. It is designed to integrate raster/grid capabilities into your own applications. Developers have access to raster/grid read and write capabilities, processing, and analysis operations, to automate repetitive operations or extend the capabilities of their applications to perform custom tasks and work flows.
Sample code and documentation for the SDK are installed with the MapInfo Pro software files. To find it, navigate to the folder containing the MapInfo Pro installation and look under the sub-folder \Raster\Documentation\API. These SDK capabilities require a MapInfo Pro Advanced license on the computer.
