GeoAce is a super-easy-to-use surveying application, for both surveyors and non-surveyors, who want to accurately collect geospatial data or locate (stakeout) such data on-site. GeoAce turns your smartphone or tablet into a precise, centimeter-accurate surveying system, without the need to use GNSS receivers or total stations. It uses Visual SLAM positioning and Augmented Reality technology to accurately determine the position of your smartphone/tablet in space and collect 3-dimensional data at the same time directly in the video stream. It doesn’t rely on GNSS positioning, so it can be used also indoors, under tree coverage and even in underground mining. You can connect external GNSS receivers to further increase the versatility of the application and accuracy. You can upgrade your GNSS receivers from Leica, Trimble, eSurvey, Stonex, Emlid and others with GeoAce to an Augmented Reality rover working everywhere, even in areas where GNSS usually wont work. The results are ready to use drawings in PDF and standard CAD & GIS formats. GeoAce doesn’t require a network connection and all processing and exporting is done on the device.
