Maxwell Systems introduces Quest Earthwork 7.5, the latest release of its earth-measuring software. Customers can use the software in conjunction with advanced machine control systems, which offer increased accuracy with the latest laser; GPS; and machine-control applications. Quest Earthwork 7.5 integrates directly with machine-control systems by exporting data in the required file formats. Users have the ability to view the entire site, or pinpoint exact sub-grade areas and contours for staking, layout and machine control.
