Geographic Transformer is a Home & Education software developed by Blue Marble Geographics. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Geographic Transformer:

This raster reprojection tool is based on our core coordinate conversion technology. The Transformer allows you to reference an image from either an existing reference file, or by using our popular “point-and-click” method with an already referenced image. The tool essentially sets up a relationship between known control points and the associated Pixels values of your image. The Transformer also allows for complex reprojection of raster data. Support for all the major GIS file formats including compression formats such as ECW, JPG2000, and MrSID. You can save your work out in whatever file format you need as one image, a mosaic of images or smaller Tiled pieces.

Now featuring MrSID write! One of the only applications available on the market with this feature. Includes 500MBs of MrSID write free with purchase of the Geographic Transformer 5.2!

Image data sources including scanned paper maps, aerial photos, and satellite imagery become powerful when reprojected as image maps for use as a background, or base map upon which other spatial data is overlaid. The Geographic Transformer allows you to easily establish an "image-to-world" relationship between image and map coordinates and reproject an image into a georeferenced image map.
