Surface Elevation Reader

Surface Elevation Reader helps surveyors, engineers, and GIS users quickly look up elevations from a TIN surface on mobile. What it does • Import LandXML surfaces (TIN) from AndroidManifest.xml files (e.g., exported from Civil 3D/LandXML workflows) • Store surfaces locally so you can reuse them without re-importing • Select between multiple surfaces you’ve imported • Enter Easting and Northing to compute the surface elevation • Optionally enter an Actual elevation to see Δ (Actual − Computed) for fast checks/QA • Clear feedback when a point is outside the surface (not inside any triangle) How it works • Reads LandXML points/faces and builds the TIN triangle set • Calculates elevation at the requested coordinate based on the triangle containing the point • Saves imported surfaces to a local SQLite database on your device Notes • Works with coordinate order variations (Easting/Northing vs Northing/Easting) found in LandXML. • No account required; data stays on-device.
