Bearing & distance, traverse closure, area & perimeter, chainage, and offset lines — 5 calculators for field survey data. Type in coordinates directly, or paste from your field notes. All math runs on the server in proper projected units.
5 Survey Calculators, Explained
Bearing & Distance
Compute the bearing and distance between two points, or find a destination point from a start, bearing, and distance.
Traverse Calculator
Compute station coordinates from a sequence of bearing/distance legs, with closure checking and Bowditch adjustment.
Area & Perimeter
Type in a boundary's coordinates directly and get accurate area and perimeter — for quick field-sketch calculations.
Chainage / Stationing
Generate regular station points along a road, pipeline, or canal alignment, with cumulative chainage.
Offset / Parallel Line
Generate a parallel line at a fixed perpendicular distance — for right-of-way or setback boundaries.
Frequently Asked Questions
Can I enter bearings as quadrant bearing or azimuth?
Both. Choose your input format (quadrant bearing like N45°30'E, or azimuth 0-360°), and results always show both formats together.
Does the Traverse Calculator check for closure errors?
Yes — for a closed traverse, it reports the linear misclosure distance, direction, and accuracy ratio, and can apply a Bowditch (compass rule) adjustment to close it.
Can I use Latitude/Longitude instead of Easting/Northing?
Yes — every calculator supports both. Geographic (lat/lon) coordinates are automatically reprojected to a local UTM zone for accurate real-world distance and area calculations.
Is this free to use for commercial or professional survey work?
Yes, free for any use. For larger survey projects or custom workflows, Sagarmekhla GIS Consultancy offers professional GIS and survey support services.
