MapInfo Pro supports raster image display. Raster images are computerized pictures. These graphic images can be used as backgrounds for maps you create in MapInfo Pro and can serve as a reference for your displayed data.
When you bring in a raster image to MapInfo Pro, you may need to register it (specify its map coordinates) so MapInfo Pro can display it properly. Choosing the Raster Image file format from the Open dialog box will bring you to the Image Registration dialog box where you can specify the appropriate map coordinates. Once you register the image, a process that creates a .TAB file for the image, you can open it as you would open any table in a Map window. Images that you purchase from MapInfo Pro will already be registered.
If a raster image is georeferenced it will be automatically opened. If a raster image has an associated world file, you will be prompted to choose the projection. If you open a raster image that does not have any georeferencing data, you will be prompted to display or register the image.
For a full discussion of raster image display, see Registering SPOT Images in the Help System.

The MapInfo Pro raster handlers support:
- LeadTools to version 15
- MrSID SDK (3.2), to provide support for MG3 files
- Multi-threading; specifically for ECW and the Government handlers (ADRG, ASRP, CADRG, CIB, NITF)
AirPhotoUSA provides raster images at different elevations for particular areas in the United States. The AirPhotoUSA map handler allows MapInfo Pro users to open and display the imagery contained in AirPhotoUSA Map files as a layer. These files are treated just like any other raster file in MapInfo Pro. The MAPINFOW.PRJ file contains AirPhotoUSA information.
You can use the AirPhotoUSA Conterminous U.S. coordinate system without making any changes. However, if you want MapInfo Pro to recognize and give a name to that coordinate system, or to use it for other purposes, you must add it to the MAPINFOW.PRJ.
