Abstract Laser scanning in cadastral activities is a tool for obtaining information about real estate objects in a 3D format. The purpose of the research is to obtain information that is necessary for state cadastral registration and state registration of rights, land supervision and local government oversight. Deductive, inductive, analytical, comparative-legal and other scientific methods were used for the most complete coverage of the problem. The article considers the procedure of laser scanning, shooting modes when using laser scanning and the process of a real estate object 3D model creation. The methods of scanning were studied, namely: terrestrial, airborne and mobile. The greatest attention is paid to the advantages and features of using laser scanning technologies for real property. The results of the study showed that the laser scanner can be used not only in geodesy for engineering surveys, 3D modeling of quarries, when obtaining data on the volume of rock, during mining, assessing the situation in an emergency, but it can also be used in cadastral and complex cadastral works. The main attribute of laser scanning is a three-dimensional representation of data about the object, which can be immediately used, but the high accuracy and low labor costs are no less important. Therefore, three-dimensional laser scanning technologies can be used both in the creation of models of cities, and the unified cartographic basis of the Unified State Register of Real Estate, as well as in valuation activities during the taxation of buildings and structures.

The authors present the results of theoretical and experimental studies on the use of laser scanning technology for the 3D-modeling of real estate objects in the cadastre. The result of the theoretical part of the research was a set of parameters for 3D modeling of real estate objects influencing the choice of the scanning method (ground, air or mobile), which showed that when creating separate 3D models of real estate objects (buildings, structures, premises and objects of unfinished construction) the method of ground-based laser scanning should be used. Based on the theoretical part, an experiment on 3D-modeling of a typical real estate object (building) was performed on the basis of data obtained with the method of ground- based laser scanning. The model of the real estate object was built with various degrees of detail to demonstrate its accuracy characteristics, depending on the distance from the scanner stations, the use of photographic materials, etc. The results of the experimental part of the studies show that the model obtained is in full conformity with the current requirements of the legislation in the field of cadastre. The proposed solution can be used as a methodological basis for constructing three-dimensional models in the transition of the Russian Federation to a 3D-cadastre system.

A comparative analysis of the principles of the cadastre in the most developed countries and in Russia. It is shown that some of the principles of cadastre, it is advisable to introduce into the Russian legislation. Such principles include the principle of Renzenberger, as well as the principles of Ruoff and Kuranda. The Russian inventory has more than twenty years, however, it cannot be considered complete, as registered in cadastre only 60 % of real estate. Full filling of the cadastre information on real estate is possible, if we abandon the application of the principle of reference. Unlike foreign domestic inventory the inventory contains errors that complicate the procedure of registration of immovable property. In addition, the domestic inventory is not the only source of information about the property that causes the ambiguity of the information about the same object. Important is also that the damage caused inaccurate inventory information bona fide buyer or seller of real property under current law, does not exceed one million rubles, regardless of the value of the lost object. Foreign inventory recognizes the property owner the main participant of the changes, however, the Russian legislation allows for the adjustment of the information object without the application of the property owner. See principles of the foreign inventory is useful for the maintenance of the national cadastre. This will simplify the process of state cadastral accounting of real estate, reduce the time of its formation and to increase the reliability of materials of the Unified state register of real estate.

Within the last years terrestrial and airborne laser scanning has become a powerful technique for fast and efficient three-dimensional data acquisition of different kinds of objects. Airborne laser system (LiDAR) collects accurate georeferenced data of extremely large areas very quickly while the terrestrial laser scanner produces dense and geometrically accurate data. The combination of these two segments of laser scanning provides different areas of application. One of the applications is in the process of reconstruction of objects. Objects recorded with laser scanning technology and transferred into the final model represent the basis for building an object as it was original. In this paper, there will be shown two case studies based on usage of airborne and terrestrial laser scanning and processing of the data collected by them.

Spatial Attributes

The Dual-Wavelength Echidna Lidar (DWEL), a full waveform terrestrial laser scanner (TLS), has been used to scan a variety of forested and agricultural environments. From these scanning campaigns, we summarize the benefits and challenges given by DWEL's novel coaxial dual-wavelength scanning technology, particularly for the three-dimensional (3D) classification of vegetation elements. Simultaneous scanning at both 1064 nm and 1548 nm by DWEL instruments provides a new spectral dimension to TLS data that joins the 3D spatial dimension of lidar as an information source. Our point cloud classification algorithm explores the utilization of both spectral and spatial attributes of individual points from DWEL scans and highlights the strengths and weaknesses of each attribute domain. The spectral and spatial attributes for vegetation element classification each perform better in different parts of vegetation (canopy interior, fine branches, coarse trunks, etc.) and under different vegetation conditions (dead or live, leaf-on or leaf-off, water content, etc.). These environmental characteristics of vegetation, convolved with the lidar instrument specifications and lidar data quality, result in the actual capabilities of spectral and spatial attributes to classify vegetation elements in 3D space. The spectral and spatial information domains thus complement each other in the classification process. The joint use of both not only enhances the classification accuracy but also reduces its variance across the multiple vegetation types we have examined, highlighting the value of the DWEL as a new source of 3D spectral information. Wider deployment of the DWEL instruments is in practice currently held back by challenges in instrument development and the demands of data processing required by coaxial dual- or multi-wavelength scanning. But the simultaneous 3D acquisition of both spectral and spatial features, offered by new multispectral scanning instruments such as the DWEL, opens doors to study biophysical and biochemical properties of forested and agricultural ecosystems at more detailed scales.

Height Change

The boreal tree line is in many places expected to advance upwards into the mountains due to climate change. This study aimed to develop a general method for estimation of vegetation height change in general, and change in tree height more specifically, for small geographical domains utilizing bi-temporal airborne laser scanner (ALS) data. The domains subject to estimation may subsequently be used to monitor vegetation and tree height change with detailed temporal and geographical resolutions. A method was developed with particular focus on statistically rigorous estimators of uncertainty for change estimates. The method employed model-dependent statistical inference. The method was demonstrated in a 12 ha study site in a boreal–alpine tree line in southeastern Norway, in which 316 trees were measured on the ground in 2006 and 2012 and ALS data were acquired in two temporally coincident campaigns. The trees ranged from 0.11 m to 5.20 m in height. Average growth in height was 0.19 m. Regression models were used to predict and estimate change. By following the area-based approach, predictions were produced for every individual 2 m2 population element that tessellated the study area. Two demonstrations of the method are provided in which separate height change estimates were calculated for domains of size 1.5 ha or greater. Differences in height change estimates among such small domains illustrate how change patterns may vary over the landscape. Model-dependent mean square error estimates for the height change estimators that accounted for (1) model parameter uncertainty, (2) residual variance, and (3) residual covariance are provided. Findings suggested that the two latter sources of uncertainty could be ignored in the uncertainty analysis. The proposed estimators are likely to work well for estimation of differences in height change along a gradient of small monitoring units, like the 1.5 ha cells used for demonstration purposes, and thus may potentially be used to monitor tree line migration over time.

Abstract. This study aims to introduce triangulation and ToF measurement techniques used in three-dimensional modelling of cultural heritages. These measurement techniques are traditional photogrammetry, SfM approach, laser scanning and time-of-flight camera. The computer based approach to photogrammetric measurement that is named SfM creates dense point cloud data in a short time. It is low-cost and very easy to application. However traditional photogrammetry needs a huge effort for creating 3D wire-frame model. On the other hand active measurement techniques such as terrestrial laser scanner and time-of-flight camera have also been used in three-dimensional modelling for more than twenty years. Each one has specific accuracy and measurement effectiveness. The large or small structures have different characters, and require proper measurement configurations. In this study, after these methods are introduced, their superior and weak properties in cultural heritage modelling to make high accuracy, high density and labour and cost effective measurement.
