Geographic Imager enhances Photoshop by adding tools and technology to support the import, edit, manipulation and export of geospatial images, such as aerial and satellite imagery. It allows the use of Photoshop's native imaging functions, such as cropping, transparencies, individual pixel editing and brightness/contrast control, while adding the ability to import and recognize GeoTIFFs and other raster formats, automatically mosaic and tile images, reproject and transform images, geo-reference images based on ground control points, and re-export images with all spatial information intact.

New in version 2.5 is import support for the following DEM formats: Arc/Info ASCII Grid & Binary Grid, DEM USGS/CDED ASCII, Military Elevation Data/DTED, SDTS transfer and SRTM, as well as import support for ECW, JPEG 2000, MrSID, PCI EASI/PACE and SGI. A new automatic coordinate system transformation during mosaicking allows images with different coordinate systems and pixel sizes to be mosaicked by automatically transforming the images to the same coordinate system and pixel size as the destination image in a single process. Also new is the ability to crops incoming images to a specified size upon import, which allows large images that could not be opened to be successfully imported.

Geographic Imager, for Mac and Windows Adobe Photoshop CS3 and CS4, can be purchased for $699 on the Avenza site, with the availability of version 2.5 set for Q3 2009. A trial version is also available for download.
