iAdjust handles traverse, angle-distance, leveling, detail-control and trig-height adjustment, with closure checks, least-squares, graphics, reports and cloud files.
iAdjust is a professional tool for engineering surveying, control surveying, and least-squares adjustment computation. It is designed for data processing and deliverable preparation for common surveying projects, including traverses, angle-distance networks, angle-only networks, leveling networks, mapping control networks, and trigonometric leveling.
Key features:
- Supports input of survey stations, known control points, direction observations, distance observations, and height differences
- Supports computation for traverse, angle-distance network, angle-only network, leveling network, mapping control network, and trigonometric leveling projects
- Supports misclosure checks, approximate coordinate computation, rigorous least-squares adjustment, and precision analysis
- Supports viewing control network diagrams, closure routes, error ellipses, and result graphics
- Supports reports for adjustment results, coordinate results, elevation results, direction observations, distance observations, point precision, and point-to-point errors
- Supports result analysis, accuracy class compliance checks, and suspicious observation alerts
- Supports management of local files, sample files, and cloud files
- Supports result export for review, archiving, and submission
- After purchasing a plan, both the App and Web versions are available
iAdjust includes multiple built-in surveying sample files, helping users quickly understand the calculation workflows for traverse, angle-distance network, leveling network, angle-only network, and mapping control network projects. It is suitable for surveying and mapping, construction staking, engineering control surveys, leveling surveys, result verification, and least-squares adjustment computation.
