RF-PAIT Merge is used for mixing area coverage maps with elevation color coded maps. RF-PAIT Merge is an interactive tool that can be used to overlay the coverage map with the elevation map or any raster image such as USGS maps by adjusting the alpha channel. The desired image can be exported as JPEG or GIF. RFPaitMerge eliminates the need for a GIS package or cumbersome imports into drawing tools. At the same time, exported images from RFPaitMerge are ready for direct import into GIS programs. RF-PAIT merge also allows for the adjustment of threshold colors. Other options include coverage inclusion and exclusion. RF-PAIT Merge is included with the purchase of RF-PAIT.
