## What is GeoAce?

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.

### 3/5 — Bin nicht so begeistert

*2023-09-22*

Wir bauen eine neue Garage und haben die Anschlüsse für Regenwasser, Heizung, Strom und Kommunikation im Erdboden verlegt. Ich war auf der Suche nach einer App, mit der ich die genaue Position der Leitungen im Untergrund dokumentieren kann. Ich dachte, dass diese App genau das leisten kann. Die Aufnahme der Leitungsposition im Virtual Reality Modus hat sehr gut funktioniert. Klasse! aber als ich eine Zeichnung mit der Lage der Rohre als PDF exportieren wollte, wurde ich enttäuscht. Sobald eine Hintergrund Karte aktiv ist, lässt der Zoom nur einen sehr oberflächlichen Blick zu. Das ist für mich ungenügend. Auch scheint sich die Lage einer Leitung nachträglich verschoben zu haben. Wenn ich ohne Hintergrundkarte exportiere, dann kann ich zwar genügend weit hineinzoomen, jedoch fehlen mir dann die Umrisse von Haus und Garage, so dass es nicht mehr möglich ist, die Lage der Rohre zu erkennen.

### 4/5 — Export in .dwg

*2023-02-08*

Ein Export im DWG-Format wäre noch super.

### 5/5 — Das ist die Zukunft.

*2021-01-18*

Super App einfache Handhabung und super Ergebnisse, was will man mehr.
