Forward Coordinates Calculator
New point coordinates from a known station + bearing + distance.
sin pairs with EASTING (not northing) because bearings start at north — the #1 sign mistake in hand traverse computation. Departure = d·sinθ, latitude = d·cosθ.
Formula
Forward Coordinates Calculator is a free forward computation for surveyors, civil engineers and property buyers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Forward Coordinates Calculator
New point coordinates from a known station + bearing + distance. The calculation implements E₂ = E₁ + d·sinθ; N₂ = N₁ + d·cosθ (Traverse computation — surveying texts). sin pairs with EASTING (not northing) because bearings start at north — the #1 sign mistake in hand traverse computation. Departure = d·sinθ, latitude = d·cosθ.

Frequently asked questions
What formula does the Forward Coordinates Calculator use?+
It computes E₂ = E₁ + d·sinθ; N₂ = N₁ + d·cosθ, per Traverse computation — surveying texts. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
sin pairs with EASTING (not northing) because bearings start at north — the #1 sign mistake in hand traverse computation. Departure = d·sinθ, latitude = d·cosθ.
Are regional land units exact?+
Conversion factors follow state revenue-department values noted on the tool. Units like bigha and katha vary by region, so always confirm the local factor named in your land records.
Is the Forward Coordinates Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
