Surplus

SurPlus is an engineering measurement application developed for high-precision GNSS System . The development team, drawing upon years of surveying development and market experience, designed this application by integrating the usage habits of industry professionals and the operating style of Android. The result is a powerful yet user-friendly engineering measurement application that includes features such as high-precision point measurement, point and line stakeout, road design stakeout, CAD, and more. The software is characterized by its simple and user-friendly operation, easy-to-learn humanized workflow, robust road design and construction stakeout capabilities, powerful CAD mapping and stakeout functions, and a convenient user-customizable menu for feature display.

The software primarily consists of four main sections: Project, Device, Measurement, and Tools. Here is a brief overview of the basic functions within each section:

Project

This section is primarily focused on project configuration, data management, and software settings. It encompasses various functions, including project management, file management, coordinate systems, transformation parameters, base station translation, coordinate point database, data export, code management, software settings, and information about the software.

Device

This section primarily focuses on operations related to connecting high-precision GNSS instruments and configuring instrument. It includes functions such as communication settings, rover mode, base station mode, static mode, instrument information, instrument settings, repositioning, and instrument registration.

Measurement

This section primarily focuses on field data measurement, layout, and industry applications using GNSS positioning. It includes functions such as point measurement, partial measurement, control point measurement, CAD (Computer-Aided Design), point stakeout, line stakeout, road stakeout, and more.

Tools

This section primarily includes various practical tools related to field measurements. It encompasses functions such as coordinate transformation, file conversion, angle transformation, perimeter and area calculation, earthwork calculation, post-measurement correction, file sharing, eccentric point calculation, bearing and distance calculation, point-to-line calculation, three-point circle center calculation, average calculation, spatial distance, and more
