Introducing DendroCloud

Three-dimensional point cloud capture devices and data processing are key technologies for detailed 3D forest modelling and precise measurements. DendroCloud is an advanced software solution focused on needs of foresters, forest managers and researchers. It allows to process 3D points clouds and extract high resolution DEM, DSM, classify point clouds, measure and model individual trees.

Data sources

Three dimensional point clouds describe forests in very high detail and precision. Point clouds are usually captured by terrestrial laser scanning or close-range photogrammetry. DendroCloud supports industrial standards used for point clouds exchange. You can easily import point clouds in LAS, CSV and IGES files. Laser file format (LAS) is most widely used format used for exchange of terrestrial or aerial laser scan data. Processed data can be exported to CSV or VRML. Comma separated values files (CSV) are text files, which contains data in the table form. CSV files can be imported into spreadsheets, databases, statistical and other programs.

Terrestrial laser scanning

Terrestrial laser scanner allows to capture clouds in a short time with high density and accuracy. Point cloud can be colourized by photographs taken by internal camera.

Mobile laser scanning

Laser scanners and cameras mounted on a vehicle is an efficient solution, which is suitable for obtaining point clouds from large areas, including forest roads and forest stands.

Close-range photogrammetry

Close-range photogrammetry is an alternative technology to laser scanning, which allows to derive point clouds from a series of digital photographs.

Point cloud filters

Filtering is a very important step in point cloud proceessing. Filters are used to reduce noise, eliminate false reflections of a laser beam, classify and extract points. Point cloud filters significantly reduce data volume and computation time. DendroCloud offers a rich set of the point cloud filtering algorithms.

DEM and DSM

A digital elevation model (DEM) is an important data layer for point cloud segmentation, 3D visualisations. Horizontal cross-sections of point cloud parallel to terrain are used for estimation of stem diameters at given heights above the ground. Upper surface of forest stands and trees is described by a digital surface model (DSM), which is used in tree height estimation procedures. High-resolution DEM and DSM can be derived from input point cloud by DendroCloud's tools. Moreover, extracted DEMs can be used in wide range of applications in hydrologic modelling, potential erosion models, terrain stability studies, soil mapping, etc.

Tree measurements

The measurements and reconstructions of trees from point clouds are significant breakthroughs in forest inventory. 3D point clouds with high resolution and accuracy capture position, shape and size of trees. Commonly used tree parameters include diameter at breast hight (DBH), girth, basal area, height, crown spread and volume. The automated procedures of DendroCloud are used to classify single trees and to develop precise 3D models of trunks. Position, diameter at breast height, stem profile and height can be estimated from point cloud for each tree on a plot.
