測量 座標計算 vs Sokuten

This application employs the reverse traverse method used in construction. Simply using this application onsite will relieve you from the effort of pointless calculations with a scientific calculator by calculating numbers for you. [Reverse Traverse Method] By inputting the XY coordinates of the instrument and backsight points, then inputting unspecified XY coordinates, the contained angle and distance will be calculated. Elevation can also be calculated.

Read SIMA files, compute coordinates on site, and write them back — entirely on your iPhone. A coordinate calculator built for field surveying in Japan. ■ SIMA (survey data exchange format) support Import SIMA files received via AirDrop or the Files app. Unreadable lines never stop the import: a report tells you which lines were skipped and why, and unrecognized records are preserved verbatim and written back in place on export. ■ Seven field calculations Inverse (distance, bearing, height difference), radiation, open/closed traverse with closure error and compass-rule adjustment, intersection, area (coordinate method), offset stakes, and perpendicular foot. Register any result as a new point with one tap. ■ Input built for the field A large keypad, one-tap switching between DD.MMSS and decimal degrees, intuitive negative coordinates, and high-contrast display for outdoor readability. ■ Designed so data survives Atomic saves with three generations of automatic backups. If a save ever fails you are told immediately and can retry. No network access; your data is never sent to our servers. ■ No subscription All calculations and SIMA import (up to 50 points) are free to try. Sokuten Pro (one-time purchase — see the App Store listing for current pricing) unlocks unlimited points, SIMA/CSV export, and unlimited history. Note: Verify results before relying on them. For public survey or registration deliverables, follow the Survey Act and your client's specifications.
