The rapid growth of geo-information technology capabilities in the field of spatial data processing and analysis has led to a significant growth of the role of geo-information systems in different areas of human activity. Application of approaches to spatial information processing from satellites new for more effective and efficient assessment of the state of plant cover is caused by growing tendency of availability to data of Earth remote sensing. The article offers an information system that allows to quickly and conveniently track changes in the vegetation. The analysis was carried out on the example of the Chornobyl Area between 2000 and 2020. The Chornobyl Disaster coincides with the period of intensive vegetative plant development. During that period, they are most sensitive to radiation. It has been established that for defining the quantitative state of biomass the NDVI index at different time intervals is most often used. But this index becomes ineffective during periods of weakening of active phase of vegetation. This is therefore of practical interest to assess the possibility of using the K-means clustering for the analysis of space images of vegetation cover at different phases of vegetation. As a result of the research, water surface, land with and without vegetation has been correctly interpreted, thus determining the land with a sparse vegetation and dense vegetation cover. The maps of the vegetation cover according to the normalized vegetative index using the K-medium method were constructed, the method by which changes in vegetation over 20 years can be clearly observed. The accuracy results were verified with the Common Method Bias. According to the calculations, despite all natural cataclysms (temperature increase, drought, winter anomalies of precipitations and temperatures, storms, forest fires), as well as human activity (sanitary clear cuttings, illegal logging), vegetation in the Chornobyl zone continues to grow and its areas will increase, although not so quickly.

Information technology is developed to assist people in minimizing processing time, reducing errors, increasing the accuracy and simplifying the overall process. The process of recording, retrieving and displaying data and information can thus be easily and accurately undertaken. Information technology in its initial development, however, tends to be too costly and complicated to make a real particularly for people in developing countries. Fortunately, universities as the centers of innovation, can be a game changer for the adoption of the innovative processes, for the benefits of the community at large. In all Indonesian universities, this role is associated with a, so called Tri Dharma Perguruan Tinggi (Three Devotions of Higher Education, TDHE). This paper examines the acceptance of the collaborating officials and the obstacles i.e. internal and environmental factors. We proposed the use of GIS-based technology to coordinate the administrative units of local government at all levels, particularly the Kelurahan as the lowest hierarchy of the administrative unit in local government system. The Kelurahan will then be the spearhead in a local government system in Indonesia in promoting administrative services to all Citizens. We undertook an integrated training and tutorial for select official staff of the Kelurahan on the system. Evaluation of shows that the information system can be used to simplify the collaborators’ activities. The evaluation was done through in-depth interview to the collaborating officials. The collaborators interested in learning more about the system as an innovative way in providing service to the community as well as spatial data input to support urban planning and management.

Spatial Data Warehouse

This paper describes the spatial information system infrastructure implemented by the Illinois Department of Transportation (IDOT) to enable delivery of information to management decision makers in asset management applications. This spatial data warehouse infrastructure makes extensive use of geographic information system (GIS) technologies to integrate information from a variety of database structures and formats. GIS products and tools have been developed to portray and analyze these data in useful combinations focused on practitioner needs. In June 1999 the Governmental Accounting Standards Board issued Statement 34 requiring governments to have a systematic approach to managing their assets. As a result, transportation agencies have placed an increased emphasis on developing mechanisms to integrate information from disparate management information systems and legacy databases. IDOT has used GIS to develop a spatial data warehouse to enable integration. A valuable characteristic of the department's information systems infrastructure is the embedding of the underlying link–node structure into roadway inventory databases to enable the direct linkage of data through various system identifiers, including differing milepost referencing and project numbering schemes. This direct linkage enables the complex integration of asset management–related data files across the enterprise and provides access to historical asset information. Changes to route referencing systems are readily accommodated, without loss of integrative capabilities. Outputs include a variety of user-developed analyses and output products with accessibility through networks, intranets, and the Internet.

Archaeology is closely associated with spatial or spatial aspects. Because the material archeological data such as artifacts, features, buildings, and sites containing the inherent spatial information in order to keep the data context. The themes of the archaeological research nowadays often reconstructing the spatial aspects of history and culture. Device Geographic Information System (GIS) is clearly greatly assist the process of archaeological research both in the field and during the process of analysis and presentation of information related to the results of the research. GIS has become the main choice for researchers to update the development of archeology that have been all-digital, practical, and effective. Although the use of GIS in archaeological research is very popular in many countries, in fact the use of GIS in archaeological research in Indonesia is still not that popular. This paper presents the use of GIS tools that allowed to be applied by archaeologists that can be adopted in the analysis and presentation of information and research results, conditions of application of GIS in the current archaeological research, as well as the constraints faced. This paper shows that recently the archaeologists in Indonesia is very enthusiactic in using the GIS for the effective spatial analysis tools. The government is also concerned about the importance of GIS in mapping the spatial data of heritage as well archaeological research locations in order to support the acceleration of One Map Policy.Ilmu arkeologi sangat erat kaitannya dengan aspek keruangan atau spasial. Karena materi data arkeologi seperti artefak, fitur, bangunan, dan situs mengandung informasi spasial yang melekat agar tidak kehilangan data konteksnya. Tema-tema penelitian arkeologi dewasa ini tidak sedikit yang bertemakan aspek spasial dalam merekonstruksi sejarah dan budaya. Perangkat Sistem Informasi Geografis (SIG) jelas sangat membantu proses penelitian arkeologi baik di lapangan maupun saat proses analisis dan penyajian informasi terkait hasil penelitian semacam itu. SIG menjadi pilihan bagi peneliti arkeologi dalam mengikuti perkembangan dunia riset yang serba digital, praktis, dan efektif.

AbstractBecause of the increased demand for information, the scientific community have published their results on the Internet over the last 20 years, adapting to society requirements. Due to the development of web-based spatial information soil systems, access to data on various themes and of varying quality has become substantially easier. The focus of our paper is to demonstrate a freely accessible and usable web-based soil database and soil information system (Soil Information and Soil Classifier System), which is suitable for geovisualization uploaded soil data and for determining reference soil groups (RSGs) in accordance with the World Reference Base of Soil Resources (WRB; RSG). In order to achieve this, we algorithmized the diagnostic soil classification process of the WRB, then we created decision trees to correspond input soil data to the WRB system. In order to facilitate geovisualization of the spatial data, the Keyhole Markup Language file format supported by Google API was applied.
