Mine Survey is a smart and easy-to-use surveying tool designed for professionals working in mining operations. The app helps surveyors measure, record, and analyze mine data quickly and accurately, saving hours of manual work. With powerful built-in tools, you can measure mine areas, calculate distances, record coordinates, and store survey data in multiple formats such as Latitude/Longitude, Bearing & Distance, and UTM. All collected data can be viewed directly on Google Maps for better clarity. Mine Survey also allows you to generate KML and DXF files, which are commonly used in mining workflows. You can export these files instantly and use them in your existing mapping or GIS systems. The app includes a Live Location Tracking feature that helps you trace your movement in the mine in real time. You can also import an existing map (Kasara map) and superimpose it on your live mine location to check accuracy, detect changes, and verify mine boundaries. Mine Survey is built to make your fieldwork faster, easier, and more accurate. Tasks that normally take more than 2 hours manually can now be completed within minutes using the app.
