Integration Of Geo-information Research Articles

Методология создания тактильных карт на основе интеграции геоинформационных и аддитивных технологий

The authors consider the current state of the tactile cartographic products manufacturing making the conclusion on the necessity of improving the existing techniques, as well as formalizing and automating the process of designing and further printing such maps. The authors propose a new methodological approach to creating them based on the integration of geoinformation and additive technologies. A technical solution is presented, within the framework of which a way of converting digital maps into three-dimensional models of tactile maps was developed. It has 4 stages, each one, in turn, consists of sequential operations that enable any user of the geographic information system to obtain the tactile map printed on plastic. The algorithm for conversion of digital cartographic data is implemented based on the geographic information system ArcGIS Pro, however, it is universal and can be applied to any geoinformation system that allows developing and installing the additional software modules for working with the mentioned data. Thus, the authors implemented a formalized approach to transforming digital maps into three-dimensional models of tactile ones.

GEOBIM FOR DIGITAL BUILDING PERMIT PROCESS: LEARNING FROM A CASE STUDY IN ROTTERDAM

Abstract. Among the digitalization processes which are being raised in Europe and in the world, the building permit process is seen as one of the priorities by municipalities, governmental institutions and standardization organizations. However, in current practice, the building permit issuing as well as the integration of geoinformation with BIM (GeoBIM) suffers from a number of complex sub-issues. These issues still remain and prevent the development of successful methodologies. In this paper, the building permit use case is explored within a project in close collaboration with the municipality of Rotterdam. A very specific case study in Rotterdam was selected as a starting point, which allowed us to develop the needed methodology for the implementation of an effective tool. In this paper we highlight the interpretation and formalization of regulation for building height, overhang and tower ratio. While these rules are specific to a zoning plan in Rotterdam, we believe that the methodology and encountered issues in formalizing the rules, applying the rules on delivered models and integrating various data sources (BIM and GIS specifically) are general to most building codes.

Opportunities and challenges for GeoBIM in Europe: developing a building permits use-case to raise awareness and examine technical interoperability challenges

ABSTRACTThe integration of geoinformation with BIM (GeoBIM) is critical to underpin solutions to many city-related challenges. However, to achieve an effective integration it is necessary to consider not only data and technical options but also current practice and users’ needs. This paper describes work carried out within the EuroSDR-GeoBIM project to address this challenge. After investigating potential uses for GeoBIM and existing challenges, we address a planning permits for buildings use case, to help bridging the gap between theory and practice. The resultshighlights a high-level harmonised workflow envisaging the use of GeoBIM information for automating the planning permits process.

Thinking Outside the Disciplinary Box in Coping with Dilemmas in Geoinformation Management for Public Policy

AbstractNotwithstanding optimistic rhetoric about integrating geospatial data from different sources and supporting good governance, much of the literature on geoinformation management is limited to a technical orientation with a positivist paradigm. Complex geoinformation management, like public policy, must go beyond these boundaries. The article calls attention to the underexposed role of dilemmas in geoinformation management and how to cope with them. It uses lessons from the development of ‘integrated surveys’ at the former International Training Centre for Aerial Survey (ITC) in The Netherlands as an early and practical case of managing geoinformation for public policy some 40 years ago. These lessons are apparently also relevant to modern digital geoinformation management, as in SDI. Focus on public policy requires not only integration of geospatial data from different sources but also integration of geoinformation into complex decision‐making processes. This complexity probably creates dilemmas because of mutually incompatible perspectives between different actors on what is to be managed. Geoinformation management for public policy therefore requires the ability to find, over and over again, a common ground between and beyond incompatible perspectives. The article proposes a ‘transdisciplinary’ framing of geoinformation management to support the required thinking outside the box.

Data-driven fuzzy analysis in quantitative mineral resource assessment

The integration of geo-information from multiple sources and of diverse nature in developing mineral favourability indexes (MFIs) is a well-known problem in mineral exploration and mineral resource assessment. Fuzzy set theory provides a convenient framework to combine and analyse qualitative and quantitative data independently of their source or characteristics. A novel, data-driven formulation for calculating MFIs based on fuzzy analysis is developed in this paper. Different geo-variables are considered fuzzy sets and their appropriate membership functions are defined and modelled. A new weighted average-type aggregation operator is then introduced to generate a new fuzzy set representing mineral favourability. The membership grades of the new fuzzy set are considered as the MFI. The weights for the aggregation operation combine the individual membership functions of the geo-variables, and are derived using information from training areas and L 1 regression. The technique is demonstrated in a case study of skarn tin deposits and is used to integrate geological, geochemical and magnetic data. The study area covers a total of 22.5 km 2 and is divided into 349 cells, which include nine control cells. Nine geo-variables are considered in this study. Depending on the nature of the various geo-variables, four different types of membership functions are used to model the fuzzy membership of the geo-variables involved.

Environmental geology in Thailand - programs and strategies

The paper describes the activities and objectives of the Department of Mineral Resources in the field of environmental geology. This approach is still a comparatively new for Thailand and presently comprises different programs: environmental geology for regional planning, seismic hazards, flooding/landslides, coastal management and geosites conservation. The Environmental Geology Section of the Department is the relevant administrative unit. The technical work and the related documentations focus on rising public awareness and integration of geo-information into land-use planning and land development.
