Level Calc - Levelling Survey

"Level Calc" 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.

Key Features:

1. Three Specialized Calculation Modes

GH Calc (Ground Height): Quickly calculate the Instrument Height (IH) and Ground Height (GH) by entering the Benchmark (BM), Backsight (BS), and Foresight (FS).

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.

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.

2. Accuracy & Error Checking

In Route Mode, the app verifies if your survey falls within the allowable error margin.

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).

Visual indicators (OK/NG) show instantly if the closure error is within tolerance.

3. Data Management & CSV Export

Save & Load: All calculation data can be saved to the local database and reloaded anytime.

CSV Export: Export your survey data to CSV files compatible with Excel or other spreadsheet software.

Field Note Format: The Route calculation export generates a file formatted like a traditional field book (No., BS, IH, FS, GH, Remarks).

Share: Easily share data files via email or cloud storage apps directly from the site.

4. User-Friendly Interface

Edit or delete individual survey points easily.

Add notes/remarks to each point (e.g., station names).

Clear history support.
