TopoSuite

Record survey observations, set out points, and perform geometric calculations from a mobile device with TopoSuite. Designed for land surveyors and surveying education, it brings field operations and classroom practice into one calculation workspace.

Polar and orthogonal workflows cover station orientation, free-station work, polar surveying, polar implantation, axis implantation, orthogonal tracking, and orthogonal implantation. It computes intersections for two lines, two circles, or a line paired with a circle, and handles surfaces bounded by a circular arc plus displacement of a parallel limit relative to a compulsory surface. Field and distance calculations, point-to-line projection, circle construction from three points, and circular-arc segmentation extend its geometry tools. Mathematical routines solve triangles and resolve circular elements.

Survey points and related data can be imported from CSV, LTOP, and PTP files, while results can be exported to CSV. Calculation history, points, and settings can be stored in a TPST file, then imported into another TopoSuite installation or reused in the same application.

Students can use it to practice surveying methods, while surveyors can apply the operations during fieldwork, set-out tasks, and geometric calculations. TopoSuite 1.4.0-beta.5 runs on Android 10 or later with Universal architecture and is distributed under an open-source license.
