How does theodolite app work?
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. This is useful to calculate range/distance to objects and landmarks with known height.
How does iPhone calculate slope?
Use iPhone as a level
- Open Measure.
- Tap Level, then hold iPhone against an object, such as a picture frame. Make an object level: Rotate the object and iPhone until you see green. Match the slope: Tap the screen to capture the slope of the first object.
How do you survey land on iPhone?
Here’s how it works: Just fire up Homesnap on your iPhone or iPad, pull up the home’s listing, scroll to the map, and tap “Walk the Property Lines.” As you walk the perimeter of the home, your iPhone (or iPad) will display the property lines on top of a real-time view captured by the device’s built-in camera.
How accurate is a theodolite?
A number of investigators reported results of similar tests using theodolites, not levels. For distances less than 150 m, almost all investigators reported accuracy values in the range from 1/600 to 1/2100.

Why are Clinometers inaccurate?
Measurements from the deepest part of an inclinometer casing have the highest potential for systematic errors due to four factors: (1) instrument warm-up drift being most acute, (2) calibration hysteresis more probable, (3) tendency of the borehole to drift from vertical, and (4) greatest distance from the top …
What software is used for land surveying?
Featured land surveying software Subscription includes AutoCAD, specialized toolsets, and apps. BIM 360 is a construction management platform that connects, organizes, and optimizes projects from design to construction. Plan, design, construct, and manage buildings with powerful tools for Building Information Modeling.
How is theodolite used to measure distance?
The theodolite consists of a telescope pivoted around horizontal and vertical axes so that it can measure both horizontal and vertical angles. These angles are read from circles graduated in degrees and smaller intervals of 10 or 20 minutes.
