SierraSoft Survey is a BIM software for calculation and adjustment of topographic measurements

With SierraSoft Survey, you can handle land survey of any size carried out with various types of tools, such as total stations, GPS, laser scanners or drones. The calculation of the survey can be done in different ways and the automatic drawing generation functions simplify the topographical drawing. Powerful functions are available for editing data, managing topographical drawings and solving topographical problems.

Aquisição de dados

Use os dados que já tem, sem limitações

Acquire measurements taken in the field from the most popular total stations and GPS/GNSS. Import coordinates and measurements directly from files in the instrument format. The acquired data are available in special tables for their management and subsequent calculation.

Cálculo levantamento

Quickly calculate any type of survey

Execute the calculation of mixed total station and GPS/GNSS survey data. Process all types of surveys even with different methodologies: Average readings, inverted readings, re-orientations, traverses, free stations, rototranslations, earth sphericity correction and refraction.

Compensação por mínimos quadrados

Get maximum reliability of the measurement calculation

Perform rigorous adjustments using the least squares method. Get the best possible result and display error ellipses.

Transformação coordenadas

Transforms coordinates between reference systems by calibration points

Perform coordinate transformations by specifying the calibration points with the possibility of setting the weight which can also be automatically calculated by the program depending on the distance from the baricentre and the reliability of the point. The transformations provided for are: barycentric (with or without scale change), affine, homographic, 3D Helmert, polynomial, 3D conformal.

Transformations between coordinate systems

Switch easily between different coordinate systems

Performs the transformation of coordinates between different systems: with control points, between coordinate systems (EPSG), axis inversion, etc. Transformations can be applied to points only or to all graphic entities in the project.

COGO

Create new survey points

COGO commands allow you to quickly and accurately create new survey points for intersection, offset, tangency, alignment, projection, slope, etc. speeding up drawing and data entry operations.

Códigos de levantamento

Manage information in the field and automate the design

Use the survey codes to automatically generate the break lines of the mathematical model and obtain the automatic survey design and the BIM information model. To each code it is possible to assign different parameters with which to represent the point including: symbol, size, layer.

Survey drawing

Create an accurate representation of the land

Create an accurate topographical representation of the land using drawing functions. You can customize points and lines drawings by defining styles. Use photos, satellite images, digital cartography and other models as a drawing support.

Positioning and staking out

Generate reports and data to be sent to instruments for staking out

Export data for staking out the represented elements. The formats used by the most widely used topographic instruments are managed. Generate detailed reports with all survey information.
