It looks like nothing was found at this location. This section of the app also provides a link to this help page. Tapping this button will zero all angles at a given orientation of the device, thereby showing angles relative to that reference until you tap the button again. B calculator, used for computing distances and heights, headings, and triangulations. The calibration procedure will then measure offsets in the acclerometer, gyro, and camera hardware and use them to correct measurements to match the level reference. This button toggles colored lens filters over the screen, which may be helpful to preserve night vision or improve usability in low light situations. Available colors are red, green, gold, and gray. The same button toggles the display back to normal. This button is used to take photos and screenshots or record movies. Theodolite has two modes for taking still images. If available on the device, the flash can be used in manual or automatic mode. In screenshot mode, flash is not used. In both modes, image saves are buffered and done in a background thread, so that you can continue to shoot photos while image saves are in progress. With multitasking, image saves will continue after you leave the app. Images are saved to the device photo album, and are written with an EXIF metadata record containing position, altitude, bearing, and user notes. The screen movie mode is similar to the screenshot mode, capturing the entire screen display including the full graphics overlay. Both movie modes offer multiple video quality settings, and both record audio along with video. On capable devices, the torch can be used for lighting the video scene in regular movie mode. On devices capable of HD recording, there are three video quality settings. For the best performance, processing is run in the foreground as a modal task. Theodolite will give you the option to process an interrupted recording, resume processing the movie, or delete the movie once you return to the app. After a movie has been processed, it is saved in a background thread and you can continue using Theodolite, or leave the app, while the save is in progress. Recording and processing movies in Theodolite is extremely computationally intensive, so this feature must be used carefully and wisely. Theodolite is typically used to make measurements or document observations and findings. For the fastest performance, use the regular movie mode with lower video quality settings. HD quality on devices with retina screens! Medium video quality is sufficient for most purposes, and works well in screen movie mode. To cycle through the various rangefinder reticles in Theodolite, tap the center of the screen. As an example of usage, consider the storage shed shown in the screenshot clip below. Any dimension of the object can be aligned with the reticle rings, whether vertical, horizontal, or diagonal. The rangefinder reticle rings have been setup to work on all current devices, taking into account the lens field of view and the screen resolution. Dot spacings are 20 mils at 1X zoom, 10 mils at 2X zoom, and 5 mils at 4X zoom. Next, Theodolite includes two large format stadiametric rangefinders, similar to those used by snipers, hunters, and artillerymen. By lining up the target with the curve scale, distance to the target can be estimated as a multiple of the target height. Note that the horizontal scale of the stadiametric curve is linear, such that graphical interpolation is possible. It also uses a linear horizontal scale to allow interpolation. Drag the sizing handle to the right of the square reticle to fit the reticle to a vertical or horizontal dimension of the target. These functions calculate information from two observation readings, A and B. Theodolite will remember data from both points if you leave the app before completing a calculation. For long distance measurements, you can record data at point A, leave the app, travel to point B, and reactivate the app to record data and proceed with a calculation. B functions cannot be used when Zero Ref mode is active. Tap the A button at location A, then travel to location B and tap the B button. The greater the distance between points A and B relative to the position accuracy, the better the results will be. Upon completion, points A and B will be shown on the map along with the bearing line between the two points. Aim at the bottom of the object to be measured and tap the A button, then aim at the top of the object and tap B. This is useful when you can easily make or estimate horizontal measurements but not vertical ones. You do not need to be on level ground for this measurement. Theodolite will ask you to input the height of the object, then it will calculate the approximate distance to the object based on the change in elevation angle between A and B. Then input your eye height, or more specifically, the height of your device. Theodolite will calculate the approximate distance to the object. This m filexlib.
