Visualization and measurement are key components of geospatial data. Imaging rovers reduce the cost of data acquisition while providing more information than ever before. Chris Gibson, The Next Disruptor: Changing the Business Landscape with Imaging Rovers (, 23 January 2014). Geospatial data collection techniques have evolved significantly.

The integration of vision technology in Robotic total stations some years ago was the starting point in a new era of photogrammetric techniques for geospatial data collection. This trend is growing and geospatial professionals are well positioned to take the next step; imaging rovers, mobile imaging solutions and UAS. This paper will explore the use of such technological advances in the geospatial market place and provide insight into the field to finish approach of delivering accurate and compelling datasets through the integration of digital imagery (imaging rovers, vision total stations and UAV), conventional techniques and GNSS, and 3D laser point clouds (from mobile and static solutions) with cutting edge software.
