Therefore, you easyly can measure also on the downward side of geological planes. The program calculates the precise direction of the dip.Īlso, it does not matter wheather you perform measurements in display-up or display-down device position.
You only have to place the device on the plane and adjust it roughly in the direction of the dip. You will also work faster because you don't have to adjust the iPhone on the schistosity plane. The measurements are more precice than measurements with a conventional geological compass. Using Lambert on the iPhone has a number of advantages in comparision to a conventional geological compass. The data can also be previewed in projection diagrams and transferred to your computer. All measurements will be stored and can be reviewed in data tables. Stereographic projection of a line, in this case the normal or pole to a plane. Consider the area of a sector of width A r 2 360 r2 (6. Unfortunately, the sector diagram as described here is biased in the way it presents the data, but is still the most commonly used type of display for directional data.
A common application in sedimentology is visualizing measured cross-bedding azimuths. The sedimentary Geological Survey Professional Paper - Issue 594 - Page K-20 This video tutorial is made especially for those who need to do analysis by using rose diagram. SpheriStat - orientation of spatial data for structural geology, geological engineering, sedimentology, glaciology, palaeomagnetism, physical geography. Two types of graphical presentations of directional data. Any dataset consisting of lots of measurements of direction or orientation could be visualized this way. You can use Lambert to measure the direction and the angle of dip of geological strata or for the measurement of the plunge and plunge direction of lineations. Rose diagrams, also called polar bar plots, are useful for showing azimuthal (directional) data. Lambert is an app that turns your iPhone or iPad into a geological compass.
