CadLapFree deed closure checker
Paste the courses from a deed or plat, one per line, and get the misclosure, precision ratio and area instantly. Everything runs in your browser; nothing you paste is sent anywhere.
Why we built this: closure is the first thing we check on every job before a sheet is laid out, because a figure that does not close means a dropped call, a transposed digit or a record conflict. If a deed will not close for you, that is a normal day for us: boundary survey drafting includes finding the suspect call and flagging it.
