Positioning accuracy is the single most important component when displaying spatially referenced visuals in augmented reality (AR). Without accurate placement, the utility of augmented reality is at best reduced, at worst dangerous insofar as it may help cause an accident by providing false confidence.
AR users may equip themselves with survey-grade positioning devices or may carry nothing more than a phone or a tablet. vGIS is designed to satisfy the broadest range of possible applications and to provide the best possible experience in each case.
vGIS employs several patented and patent-pending positioning technologies that are unique to vGIS in addition to the full array of industry-standard AR positioning methods . To help you assess the cost, convenience, and experience of vGIS in the context that is most relevant to you, this guide explains the pros and cons of each method.
