SierraSoft Land is a comprehensive BIM (Building Information Modeling) software solution specifically designed for the 3D modeling and analysis of land. It empowers users to efficiently manage land surveys of any scale, regardless of the acquisition tools used, such as total stations, GPS, laser scanners, or drones. The software's integrated BIM functionalities facilitate the simultaneous production, modification, sharing, and analysis of topographic information models, significantly optimizing workflows and containing costs. It provides a complete suite of tools for land survey restitution, detailed analysis, robust information modeling, and precise quantities calculation, all within a single product. This allows for seamless integration of diverse data sources and the creation of highly accurate digital representations of terrain and proposed designs.

Features & Benefits

• Data Acquisition
  • Allows seamless import and usability of diverse survey data, from a few points to massive surveys, originating from total stations, GPS, laser scanners, or drones.
• Point Clouds
  • Enables simple upload and management of one or more point clouds of any size with fast loading and display. Supports real-time drawing and extraction functions, allowing for quick model extraction and volume calculation with various methods. Includes "SierraSoft Mass Data Converter" for converting LAS, XYZ, PTS, XCF, E57, and GeoTIFF DEM files for use within the software.
• Survey Restitution
  • Automates design creation from traditional point-based surveys with codes. Offers digital survey functions for point clouds, mimicking field surveying. Provides support for restituting photos, satellite imagery, digital maps, and other models.
• Terrain Modeling
  • Generates accurate 3D terrain surfaces in a few steps, maintaining control over the outcome. Manages discontinuities and offers high processing speed for models ranging from small to large point cloud triangulations. Completes terrain models with contour lines.
• As-Found
  • Facilitates the creation of "As-Found" models by defining geometries and information content from acquired survey data, resulting in a complete and useful information model for design.
• Coordinate Systems
  • Supports a wide range of coordinate systems, including EPSG standards-based and localized systems, ensuring accuracy and consistency in design and information modeling for both geographic and projected coordinates.
• Cross Sections
  • Extracts and manages sections of 3D models automatically, either along a direction or a polygonal alignment. Allows extraction of complex sections from multiple 3D surfaces in one step using extraction styles.
• Volumes
  • Calculates volumes using various methods based on data and goals, either from a model's triangular surfaces or extracted sections. Ensures simple and extremely precise calculation for triangular surfaces.
• 3D Design
  • Enables easy design of complex surfaces with immediate 3D representation. Includes features for creating leveling, sideslopes, polylines offset, connection surfaces, and merging models and surfaces. Facilitates quick creation of precise project 3D models, including pits, dumps, parking areas, terracing, embankments, ramps, and tracks.
• Hydrological Analysis
  • Provides valuable information for hydrographic and hydrological analysis of territory and new projects. Helps analyze hydrological problems and facilitates decision-making. Generates water paths or contour lines from a point, displays slope vectors, valleys, ridges, tributaries, flat areas, and calculates basin filling volumes.
• Advanced Information Modeling
  • Defines detailed BIM models simultaneously with design, based on customizable settings. Integrates buildingSMART's IDS (Information Delivery Specifications) and bSDD (buildingSMART Data Dictionary) standards for intuitive creation, management, modification, and validation of information content, ensuring data consistency with BIM Execution Plans (BEP). Supports multidisciplinary collaboration through BCF (BIM Collaboration Format) standard implementation. (Requires SierraSoft BIM Modeling software extension).
• Information Exchange and Multi-disciplinary Integrated Design
  • Shares project information in open formats like IFC (2x3, 4.1, 4.3) and LandXML for export to other software (e.g., Revit, Tekla, ArchiCAD, Trimble Connect, usBIM). Imports information models of various works (railways, roads, hydraulic works, bridges, tunnels, buildings) for integrated design and management of federated models. (Requires SierraSoft BIM Exchange software extension).
• Information Analysis and Verification
  • Analyzes, verifies, and validates information content of BIM models simultaneously with design, identifying and resolving errors early. Identifies interferences between created and federated models, verifies structure, elements, and information content, with specific checks for topographic and infrastructural models. (Requires SierraSoft BIM Checking software extension).
• Information Documents
  • Automatically generates required information documents from project and information model data.
  • Planimetry: Project elements with dimensions.
  • Cross sections: Paginated sections with dimensions, annotations, and quantity summaries.
  • Prints: Customizable printouts of sections, quantities, and staking out data.
• Information Models in Open Formats
  • Creates customizable information models in open formats according to BIM Execution Plan (BEP) specifications. Designs in detail and creates IFC models by defining version, domain, spatial structure, elements, graphical representations, and properties. Exports LandXML models with all project data, delivering models in open formats as per BEP.
• Positioning and Construction
  • Generates reports, drawings, and models for use in positioning and construction. Exports information for topographic project positioning using staking out functions. Exports models usable by "machine control" systems for automated design and construction.
• As-Built
  • Creates "As-Built" models from data acquired during construction, representing the built environment in detail. Integrates project data with construction-acquired information, supported by design and 3D modeling tools.
• Platform for Coordination and Integration
  • Serves as a platform for coordinating multidisciplinary design by enabling model sharing. Allows import of various infrastructure models (railways, roads, hydraulic works, bridges, tunnels, buildings) to create aggregate models for design support.
