SierraSoft Survey provides a robust BIM solution for professionals involved in topographic measurements and land surveying. The software is capable of handling land surveys of any size, accommodating data from various modern tools such as total stations, GPS, laser scanners, and drones. It supports diverse calculation methodologies for surveys, including mixed total station and GPS/GNSS data, average readings, inverted readings, re-orientations, traverses, free stations, rototranslations, and corrections for earth sphericity and refraction. Users can perform rigorous adjustments using the least squares method to ensure maximum reliability and visualize error ellipses. The software offers extensive support for a wide range of coordinate systems, including EPSG standards-based systems and localized systems, ensuring accuracy and consistency in design and information modeling. It facilitates complex coordinate transformations, allowing users to switch between reference systems using calibration points and various transformation methods like barycentric, affine, homographic, 3D Helmert, polynomial, and 3D conformal. COGO commands enable the quick and accurate creation of new survey points for intersections, offsets, tangencies, and more. Survey codes streamline the management of field information and automate design processes, including the generation of break lines for the mathematical model and the creation of BIM information models. SierraSoft Survey also includes powerful functions for creating accurate topographical drawings, offering customization options for points and lines, and supporting the integration of photos, satellite images, and digital cartography as drawing aids. It supports advanced information modeling, defining BIM models in detail according to customizable settings and adhering to buildingSMART standards like IDS and bSDD for consistent data. Multidisciplinary collaboration is enhanced through BCF standard implementation. The software facilitates information exchange via IFC and LandXML formats, enabling integrated design and management of federated models with other software. It automatically generates essential information documents such as planimetry and customizable reports, and supports the generation of data for positioning and staking out. Furthermore, it allows for the creation of As-Built models by integrating project data with information acquired during the construction phase.
