Surveying Leveling Field Notes vs Hydrographic Survey

Supports automatic calculation and checking of the Height of Instrument method. You can edit column titles. You can share your document as a '.csv' file.

Hydrographic Survey puts a full levelling workflow in your pocket, no spreadsheet, no phone reception required. Open a survey, enter your backsight, intermediate, and foresight readings, and watch Rise & Fall values calculate in real time. A live MISCLOSE bar tells you instantly whether your survey closes within tolerance (2√n), so you catch errors on-site, not back at the desk. FIELD-READY FEATURES • Automatic Rise & Fall and Datum Level propagation with every reading • Live MISCLOSE quality check against the 2√n threshold; pass/fail at a glance • Portrait card view for one-handed data capture • Landscape spreadsheet view supported • Export PDF, CSV, or JSON and share directly from the device • All data stored on-device; no account, no cloud, no signal needed BUILT FOR SURVEYORS • All inputs map directly to the levelling staff readings: backsight, intermediate sight, foresight, and datum seed. The workflow mirrors a classic level book, so there’s nothing new to learn. SUBSCRIPTION • Hydrographic Survey includes a 7-day free trial with full features. When the free trial ends, your subscription automatically begins, and your payment method is charged for the monthly or yearly plan you selected, unless you cancel at least 24 hours before the trial ends. • After the trial, a subscription is required to continue creating and exporting surveys. • The subscription automatically renews at the end of each period unless it is cancelled at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours before the end of the current period. • You can manage or cancel your subscription anytime in your device's App Store account settings after purchase. Any unused portion of a free trial is forfeited when you purchase a subscription.
