BIM software for territory restitution, modeling, and analysis

SierraSoft Land is a BIM software for land restitution, modeling and analysis.
With SierraSoft Land, you can handle land survey of any size carried out with various types of tools,
such as total stations, GPS, laser scanners, and drones.
The entire flow of rendering of acquired data, 3D surface modeling, and section and volume calculation
is managed in SierraSoft Land in a simple and comprehensive way.

BIM software for land surveying

Share, collaborate, communicate.

BIM exchange - BIM for topography and infrastructures

SierraSoft Land is a BIM (Building Information Modeling) software for land rendering and modeling. BIM rendering and modelling takes place via the BIM exchange functionality, which is part of the M3 framework, and is available exclusively with SierraSoft Subscription. BIM exchange is a powerful tool that allows the integration of topography, infrastructure and construction projects within the processes, guidelines, and tools used with BIM.

Data acquisition

Use the data you have, without limitations.

Your work starts with the data you have, whether it’s points surveyed with a total station, GPS, laser scanners, or drones. SierraSoft Land has the functions to import and make your information usable; you can have a few points or a huge survey, it will be easily manageable in both cases.

Survey rendering

Manage all the information while completing and enhancing it.

Survey rendering

If you have a traditional survey performed with points and you used codes, the entire design can be created automatically.

If instead you have a point cloud, you can use the digital survey functions to survey as if you were in the countryside.

You can also take advantage of the support features to render photos, satellite imagery, digital maps, and other models.

Surface modeling

Create accurate 3D terrain surfaces.

Surface modeling

Generate accurate 3D surfaces with just a few steps, while maintaining control over the outcome.

Thanks to its discontinuities management and high processing speed, you can easily manage small models

up to the triangulation of a large point cloud. You can complete the job with contour lines.

Cross sections

Extract and manage sections of your 3D models.

Cross sections

The sections can be automatically extracted either along a direction or along a polygonal alignment.

Through the extraction styles, you can extract complex sections using multiple 3D surfaces in one step.


Calculate volumes with the best method.

You can calculate volume with different methods, depending on your data and your goals.

The calculation can be done either using a model’s triangular surfaces or extracted sections.

The calculation for triangular surfaces is quite simple to use and extremely precise.

Point clouds

Upload and manage point clouds in a very simple way.

Point clouds

Easy handle one or more point clouds of any size. Loading and display are really fast, drawing and extraction functions occur in real time. With just a few click you can extract models and calculate volumes in many different ways. A special tool “SierraSoft Mass Data Convertes” allows to convert LAS, XYZ, PTS and XCF files so that you are able to handle them with SierraSoft Land.

3D Design

Easy design of complex surfaces.

You can easily design any surface with the immediate 3D representation of the result.
Design features include the creation of leveling, sideslopes, polylines offset, connection surfaces and the merging models and surface. Get quickly extremely precise project 3D model as far as the creation of sideslopes and intersections with the existing terrain model. Enjoy designing pits, dumps, parking areas, terracing, embankings, ramps, tracks and all what is concerned with the design of models.

Multi. Multi. Multi.

Multiply your workspace.

Expand the space where you manage your surveys and models at will:
split your work between multiple windows, pages, or monitors. All data and views are synchronized in real time.
Begin a drawing in one window and continue it in another on a separate monitor.
Discover a new dimension for working.
