Recommended elevation settings - Mobile App (KB-TT015)
Elevation settings are one of the key items you need to address when configuring your vGIS experience. This configuration will be the base of where your objects will be placed in the digital space. Incorrect elevation settings can result in visuals looking oddly scaled, misplaced, or missing from the vGIS app.
Elevation configuration for the mobile app will vary depending on whether it is paired with a high-accuracy GNSS device or not. Depending on you hardware setting and work environment, there are three options that need to considered within the elevation settings for optimal configuration.
Automatic elevation correction (recommended setting) - vGIS' back end processes the discrepancies between your data and the real world correcting the position of the visuals in the the digital digital terrain model.
Fixed elevation - Fixes the elevation in respect to the digital terrain model. Ideal when dealing with unexpected inclinations in the real world, such as a highway ramp.
No correction - Will stop the system from correcting any discrepancies. Best option when working from a position below or above the digital terrain model, such as a trench or a ladder.
Follow the instructions below depending on your hardware/work environment setting:

If your data contains z-enabled elements, you might need to adjust the digital terrain model to match your data elevation. |

*Surface offset setting allows you to increase or decrease the elevation of the digital terrain model.
