The foundation of any cadastral system, the relationship between people and land, is constantly altering and cadastral systems as well have evolved over time in response to these changes. The focus of this dissertation is on understanding the cadastral system dynamism, and more specifically, the potential future changes of cadastral systems. Empirically the main focus is on the Finnish cadastral system that presents an example of a mature cadastral system with long traditions on registration of land related interests.

This dissertation suggests that the future of cadastral systems should be approached from a holistic and systemic perspective and, therefore, integrates concepts and knowledge from the disciplines of futures studies and socio-technical transition studies. The dissertation adopts a mixed method approach with a greater emphasis on qualitative research methods.

Literary sources, a Delphi questionnaire, interviews, and focus group meetings are used in data collection. This dissertation provides a refined and revised understanding of what drives change in the context of land administration and how the mature cadastral systems might develop in the future.

Exploration of emerging issues of change reveals the increasing awareness of the multi-purpose role of cadastral systems, as the identified issues range from technology-oriented ones to political, economic, environmental, and social issues.

Overall, the findings suggest that the future of cadastral systems is a complex issue that cannot be reduced to individual technologies or innovations. Rather, this dissertation argues that more emphasis should be put on the institutional foundations, i.

The academic value of this thesis is in bridging the gap between land administration literature and futures studies and socio-technical transition studies, and in creating comprehensive understanding of cadastral system dynamism. The base of evidence obtained in this research also provides new and fresh insights to actors of land administration domain.

Guinness, Robert E. In particular, we are interested in how context awareness can be used to understand the navigation needs of people using mobile computers, such as smartphones, but context awareness can also benefit other types of navigation users, such as maritime navigators. There are countless other potential applications of context awareness, but this thesis focuses on applications related to navigation.

For example, if a smartphone-based navigation system can understand when a user is walking, driving a car, or riding a train, then it can adapt its navigation algorithms to improve positioning performance.

We argue that the primary set of tools available for generating context awareness is machine learning. This thesis examines systematically the ability of existing algorithms from machine learning to endow computing systems with context awareness. Specifically, we apply machine learning techniques to tackle three different tasks related to context awareness and having applications in the field of navigation: 1 to recognize the activity of a smartphone user in an indoor office environment, 2 to recognize the mode of motion that a smartphone user is undergoing outdoors, and 3 to determine the optimal path of a ship traveling through ice-covered waters.

The diversity of these tasks was chosen intentionally to demonstrate the breadth of problems encompassed by the topic of context awareness. We adopt these seven elements to describe contextual information. For some particular tasks, machine learning has succeeded in outperforming humans, and in the future there are likely to be tasks in navigation where computers outperform humans.

One example might be the route optimization task described above. This is an example of a task where many different types of information must be fused in non-obvious ways, and it may be that computer algorithms can find better routes through ice-covered waters than even well-trained human navigators.

This thesis provides only preliminary evidence of this possibility, and future work is needed to further develop the techniques outlined here.

The same can be said of the other two navigation-related tasks examined in this thesis. Thus, 3D modeling techniques for different data sources are urgently needed. This thesis addresses techniques for automated point cloud classification and the reconstruction of 3D scenes including terrain models, 3D buildings and 3D road networks. First, georeferenced binary image processing techniques were developed for various point cloud classifications.

Second, robust methods for the pipeline from the original point cloud to 3D model construction were proposed. Fourth, different data sources for 3D model reconstruction were studied. The strengths and weaknesses of using the different data sources were addressed. Among these data sources, MLS data from three different systems were explored, and three different densities of ALS point clouds 0. The results were compared with reference data such as an orthophoto with a ground sample distance of 20cm or measured reference points from existing software to evaluate their quality.

The results showed that The resulting building models provided an average height deviation of 15 cm. A total of 2. The pixel size was determined by the average distance of input laser points. The 3D roads were reconstructed with an average width deviation of 22 cm and an average height deviation of 14 cm. The results demonstrated that This study demonstrates the operability of 3D model construction for LoDs of via the proposed methodologies and datasets.

The study is beneficial to future applications, such as 3D-model-based navigation applications, the updating of 2D topographic databases into 3D maps and rapid, large-area 3D scene reconstruction.

Laakso, Mari Finnish Geodetic Institute , Environments can be made more accessible by offering users information about barriers and objects that might hinder their progress, thus enabling more information about accessible routes.

The study delineates the relevant geospatial information needed to describe the accessibility of an environment. Even though laws, acts and regulations give thorough building requirements for creating accessible environments, there is no holistic approach in geospatial data collection to represent the accessibility of geographical spaces.

In this thesis, an information model is presented for representing the pedestrian environment. The model allows for accessibility issues and enables the use of geospatial information in pedestrian navigation applications. In addition to data contents and data modelling, this research studies how accessibility can be further increased by way of sound when communicating geospatial information. By communicating the geospatial information via sound the information content can be enhanced and usability improved.

Sonic maps create remote access to nature and enhance the accessibility of a place. In this thesis, the fundamental aim was to study the information requirements in particular situations where different kinds of pedestrian users determine which route they might successfully complete.

The results of the thesis will help data providers collect and store geospatial information, while taking accessibility issues into account, and hopefully it will raise awareness about issues pertaining to universal accessibility.

Albeit, the main effort should focus on building accessible environments; in certain situations, people face hindrances and geospatial information could enable users overcome them. Kettunen, Pyry Finnish Geodetic Institute , This dissertation applies the research and methods of spatial cognition in order to contribute to the development of wayfinding support in geospatial applications. The design and development of geospatial applications, such as interactive maps and mobile navigation applications, has been typically founded on the expertise of surveying, cartography and geoinformatics.

This has often led to relatively complex expert tools that many users find difficult to use. The research of spatial cognition can provide elementary understanding about human thinking in the use situations of these applications and supplement the knowledge gained using the usability research. Perception of landmarks along routes in nature was studied in season and time-of-day studies with participants who walked nature trails in summer, winter, day and night while thinking aloud about the surroundings.

The recall of the route was measured afterwards using sketch-map drawing and photo recognition tasks. The think-aloud protocols were analysed using classification of propositions and natural language processing. The importance of landmarks for the human route perception in nature was confirmed.

Season and time-of-day significantly affected landmark perception and, based on the results, the adaptivity of geospatial applications in the studied conditions can be improved. The transfer of the empirically acquired knowledge of the landmark perception to geoinformatics was illustrated with a formal landmark ontology for hiking in nature.

The measures of landmark recall were found unexpectedly similar in all the studied conditions. The similarity was explained by the salience of landmarks in nature and the structure of route-like sketch maps but also by the participants' conceptions on what should be drawn on maps.

Support of geospatial images for wayfinding was evaluated using a literature-based evaluation framework. Visualisation of elevation was experimented with by rendering a 3D map, a derivative of which was compared to 2D elevation visualisations in an eye-tracking study. Vertical elements and elevation were found to be central wayfinding elements in geo-images and the aerial oblique vantage point the most effective image parameter for transferring spatial knowledge.

The rendered 3D map was evaluated as cognitively demanding to look at but, however, showed potential in representing the terrain relief. The dissertation also considers challenges in the application of the methods of spatial cognition research and identifies directions for future studies.

Jokela, Jorma Finnish Geodetic Institute , The traceability chain connects length measurements to the definition of the metre. Metrological institutes implement this with sequential measurements ranging from the realization of the metre using internationally recommended procedures to practical length or distance measurements with high-precision electro-optical or mechanical instruments.

Estimating the uncertainty of measurement at every stage in the traceability chain is an essential part of the measurement result and its usability. This publication examines the traceability of a geospatial measurand, a length used in geodesy, beginning with lengths of 1-m-long quartz gauge blocks and ending with terrestrial distance measurements of up to 1 km or more. In addition, a few alternative standard baseline designs are presented. From standard baselines, the FGI transfers the traceable scale to other geodetic baselines or test fields using calibrated, high-precision electro-optical distance measurement instruments as transfer standards.

This publication shows the capability of the method, which is not utilized elsewhere, and discusses 11 scale transfer examples of it to seven baselines or test fields. The influence of atmospheric conditions is a major source of uncertainty of measurement, and it is discussed in detail in connection with a few cases.

The traceable scale transfer service of the FGI has become internationally in demand, and it makes a remarkable contribution to the ongoing European research and development projects in length metrology. Most baselines that we have measured are alive and well, and interest in them is growing. After applying the scale transfer measurements to calibration baselines and test fields, the comparable uncertainty values were from 0.

A total expanded uncertainty of 0. Useimmat mittaamamme kohteet voivat hyvin, ja kiinnostus perusviivoja kohtaan on kasvussa. Kukko, Antero Finnish Geodetic Institute , Laser scanning is a surveying technique used for mapping topography, vegetation, urban areas and infrastructure, ice, and other targets of interest.

Its application on a terrestrial mobile platform is a promising method for effectively collecting three-dimensional data for complex environments and for producing model information for location-based services necessitating rapidly collected and up-to-date data. Development of mobile laser scanning MLS systems for such purposes is presented in this study. Different aspects of this technology were analyzed in laboratory experiments, simulations and field tests, in order to understand their effects on the ranging, intensity and point cloud data, especially in terms of point distribution and accuracy.

The results showed that the proposed systems can reliably provide accurate data. It has also been shown that the various modalities of the systems allow data acquisition in numerous application scenarios and environments not previously possible. MLS improves the data output compared to terrestrial laser scanning TLS and outperforms airborne laser scanning ALS in ranging precision and point density.

As a result, MLS is well suited to fill the gap between these two previously dominant 3D data acquisition techniques. Kaartinen, Harri Finnish Geodetic Institute , Comparing different feature extraction methods based on remote sensing or remote sensing systems is difficult as there are but few common data sets or test fields with reference data of high standard available for analysis.

State-of-the-art methods and systems are often in still evolving stage and can be run only by the developers themselves. Establishing a high-quality test field is laborious, but once such a test field has been established, it becomes easier to set up the systems to collect data from the field than to collect reference data from new areas.

Comparing either different systems or the same system with different parameters is easier when the number of variables is kept to a minimum; the remotely sensed areas are kept constant and any changes in them can be controlled more easily.

The benchmarking results provide valuable information to both developers and users of remote sensing data products. The benchmarked feature extraction methods studied included extraction of buildings and individual trees using data from common test fields. The performance of the mobile laser scanning systems was benchmarked using data collected from an established urban test field.

In all cases, it was concluded that the primary factor affecting the results was the method or the system, and this enabled a high degree of comparability for the results of the given extraction or mapping tasks.

Ruotsalainen, Laura Finnish Geodetic Institute , There is a strong need for an accurate pedestrian navigation system, functional also in GNSS challenging environments, namely urban areas and indoors, for improved safety and to enhance everyday life. Pedestrian navigation is mainly needed in these environments that are challenging for GNSS but also for other RF positioning systems and some non-RF systems such as the magnetometry used for heading due to the presence of ferrous material.

Indoor and urban navigation has been an active research area for years. There is no individual system at this time that can address all needs set for pedestrian navigation in these environments, but a fused solution of different sensors can provide better accuracy, availability and continuity. Self-contained sensors, namely digital compasses for measuring heading, gyroscopes for heading changes and accelerometers for the user speed, constitute a good option for pedestrian navigation.

However, their performance suffers from noise and biases that result in large position errors increasing with time. Due to its distinctive characteristics, this vision-aiding complements other positioning technologies in order to provide better pedestrian navigation accuracy and reliability. This thesis discusses the concepts of a visual gyroscope that provides the relative user heading and a visual odometer that provides the translation of the user between the consecutive images.

Both methods use a monocular camera carried by the user. The visual gyroscope monitors the motion of virtual features, called vanishing points, arising from parallel straight lines in the scene, and from the change of their location that resolves heading, roll and pitch.

The method is applicable to the human environments as the straight lines in the structures enable the vanishing point perception. For the visual odometer, the ambiguous scale arising when using the homography between consecutive images to observe the translation is solved using two different methods. First, the scale is computed using a special configuration intended for indoors. However, the use of visual perception provides position information by exploiting a minimum of two satellites and therefore the availability of navigation solution is substantially increased.

Both methods are sufficiently tolerant for the challenges of visual perception in indoor and urban environments, namely low lighting and dynamic objects hindering the view. The heading and translation are further integrated with other positioning systems and a navigation solution is obtained. The performance of the proposed vision-aided navigation was tested in various environments, indoors and urban canyon environments to demonstrate its effectiveness.

These experiments, although of limited durations, show that visual processing efficiently complements other positioning technologies in order to provide better pedestrian navigation accuracy and reliability.
