Web1 day ago · This works pretty well on LiDAR devices (iPhone12Pro etc). On iPhone11 (non LiDAR) the node is not always positioned on a plane and is too close to camera and does not change focus square to horizontal or vertical plane alignment. I have checked the Default measure app from Apple and this puts nodes correctly on planes and detects … WebSince the returning echo traveled to the bottom and back, the water depth corresponds to half the time it takes for an echo to return, multiplied by the speed of sound in water (Figure 1.4.3): depth=1/2*(two-way travel time)*(speed of sound in water) Figure 1.4.3 Measuring depth using an echosounder (Public domain via Wikimedia Commons).
WebDepth of inundation in 1 m intervals of accurate DEM data from LiDAR provided the ability to also determine the depth of inundation. This information is particularly useful to prioritising the risk to life and properties. For example where the depth of inundation exceeds a certain depth then it will be necessary to evacuate people from their
