Горный компас by Каталог Минералов is an Android application designed for geologists and mining engineers to use during field exploration. It allows users to determine the elements of the rock layer's occurrence such as the lines of extension and fall, measure the angle of fall, store this data with accurate geographical coordinates, and build a geological route through these points with the ability to add photos and text notes.

The app can determine the azimuth of the rock layer extension, calculate the angle of fall, and define the exact coordinates of the measurement location on the map. It can save photos taken at these points and add text notes with geotags. Users can save an unlimited number of points and build a route through them. Additionally, data can be imported to a computer for further processing.

In the future, Горный компас will be able to make an unlimited number of routes and several sets of measurements for each point. Overall, the app is an excellent tool for geologists and mining engineers on field trips.
