Contour - Volume - Stakeout

Contour - Volume - Stakeout is a field surveying and navigation app for creating contour maps, calculating earthwork volumes, and staking out coordinates with high accuracy. It helps surveyors, site engineers, and contractors get fast, reliable results on construction sites, mines, farms, and grading projects. Core features focus on three essentials: contour mapping for terrain visualization, volume calculation for cut and fill or stockpiles, and stakeout navigation that guides you precisely to points, lines, and offsets. It supports GNSS and RTK receivers for centimeter-level positioning, works offline with cached maps, and integrates with CAD and GIS through flexible CSV and DXF import and export. Keywords include surveying app, contour mapping, earthwork volume calculator, stakeout navigation, GNSS RTK, and field data collection.

1. Download and open the app, allow location access, then optionally connect your GNSS or RTK receiver and choose the correct coordinate system. 2. Create or open a project, import site data such as CSV or DXF if needed, and cache base maps for offline work. 3. Use Contour mode to collect elevation points or load an existing surface, set the contour interval, and generate contours to visualize terrain. 4. Switch to Volume mode, define a reference plane or surface, outline the stockpile or select surfaces, compute cut and fill, and save the report. 5. Enter Stakeout mode, select target points or lines, follow distance and direction guidance until within tolerance, then mark as staked and export results as CSV, DXF, or PDF.
