## Description

&quot;Level Calc&quot; is a simple yet powerful surveying tool designed for field work. It handles daily leveling calculations with ease, acting as a digital field book. Whether you are performing spot height checks or continuous route surveying, this app streamlines your workflow and ensures accuracy.<br><br>Key Features:<br><br>1. Three Specialized Calculation Modes<br><br>GH Calc (Ground Height): Quickly calculate the Instrument Height (IH) and Ground Height (GH) by entering the Benchmark (BM), Backsight (BS), and Foresight (FS).<br><br>FH Calc (Formation/Planned Height): Ideal for stakeout works. Enter the Design Height (FH) to instantly calculate the difference (Gap) between the planned elevation and the actual ground height.<br><br>Route Calc (Route Surveying): Supports continuous leveling with Turning Points (TP) and Intermediate Sights (IS). It automatically calculates the error of closure based on the route length and the known endpoint elevation.<br><br>2. Accuracy &amp; Error Checking<br><br>In Route Mode, the app verifies if your survey falls within the allowable error margin.<br><br>Select accuracy coefficients (K values: 2.5, 5.0, 10.0, 15.0, 20.0) corresponding to different survey grades (e.g., First to Fourth Order).<br><br>Visual indicators (OK/NG) show instantly if the closure error is within tolerance.<br><br>3. Data Management &amp; CSV Export<br><br>Save &amp; Load: All calculation data can be saved to the local database and reloaded anytime.<br><br>CSV Export: Export your survey data to CSV files compatible with Excel or other spreadsheet software.<br><br>Field Note Format: The Route calculation export generates a file formatted like a traditional field book (No., BS, IH, FS, GH, Remarks).<br><br>Share: Easily share data files via email or cloud storage apps directly from the site.<br><br>4. User-Friendly Interface<br><br>Edit or delete individual survey points easily.<br><br>Add notes/remarks to each point (e.g., station names).<br><br>Clear history support.<br><br>Who is this for?<br><br>Civil Engineers<br><br>Construction Site Managers<br><br>Land Surveyors<br><br>Architecture/Civil Engineering Students<br><br>Replace your calculator and paper field book with Level Calc for faster, error-free surveying.
