Free Viewers

Do you need free software to view your imagery files and/or GIS data?

If so, you have come to the right place!

Geomatica FreeView is an excellent choice for many users. Click the image above to download the free image viewer.

Here is a list of direct links to download four of our favorite free viewers for imagery files and/or GIS data. Each of these programs:

• Can be installed on any system running a Windows operating system.
• Will open a wide variety of GIS (i.e. vector) and imagery (i.e. raster) file formats;
• Allow you to display GIS and imagery files at the same time; and
• Contain several pre-defined histogram stretches to assist you with color balancing imagery.

Please let us know by email if any of these download links do not work!

• Cadcorp Map Express – check the bottom of the page for downloads; also opens CAD files directly
• Geomatica FreeView – you will need to register first to download this program
• Monteverdi (Orfeo ToolBox) – this program does the best job at histogram stretching (i.e. color balancing) 16-bit imagery and then exporting to a GeoTIFF
• Quantum GIS (QGIS) – this is an advanced program that can do more than open imagery files; it also works on Mac operating systems! Mac users will need to install QGIS and GDAL from here; and NumPy and Matplotlib from here. For directions opening an imagery with QGIS, see this video.
• TatukGIS Free Viewer
• TNTatlas – works on Mac OS and Windows
