The article discusses the possibilities of using geoportals as the main source of open digital cartographic data for the development of spatial thinking and skills among students. Currently insufficient attention is being paid to the development of spatial thinking skills among students. The definition of the concept of "geoportal" is given. An analysis of a number of regional geoportals in terms of their content with spatially distributed natural resource data is made as well as the variety of tools provided for working with these data. Conclusions about the criteria that a geoportal recommended for use by students to consolidate their skills in working with geospatial data should meet are made.

Purpose The purpose of this paper is to explain the rise of geospatial data, its importance for business and some of the problems associated with its development and use. Design/methodology/approach The paper reviews a certain amount of previously published literature but is based mainly on analysis of the very large number of responses to a consultation paper on geospatial data published by the UK Government. Findings The findings are that while there is strong appreciation of the potential benefits of using geospatial data, there are many barriers to the development, sharing and use of geospatial data, ranging from problems of incompatibility in data definitions and systems to regulatory issues. The implication for governments and for providers and users of geospatial data relates to the need to take a long-term approach to planning in resolving the issues identified. Research limitations/implications The research findings are limited to the UK, but similar findings would be likely in any other large Western country. Practical implications This paper confirms the need for a strong and coherent approach to the planning of geospatial data and systems for the establishment of a clear basis for the different parties to work together and the need to clearly separate the roles of the government in establishing frameworks and standards and the role of the private sector in developing applications and solutions. Social implications Society is increasingly dependent on the use of geospatial data, in improving living standards and dealing with social problems. The recommendations identified in this paper, if followed, will facilitate these improvements. Originality/value The value of this paper is the tight synthesis that it provides of a wide ranging and complex range of responses to the UK Government consultation and placing these responses in the wider context of the development of geospatial data.

AbstractThe chapter examines the role of geospatial data in Russia’s online ecosystem. Facilitated by the rise of geographic information systems and user-generated content, the distribution of geospatial data has blurred the line between physical spaces and their virtual representations. The chapter discusses different sources of these data available for Digital Russian Studies (e.g., social data and crowdsourced databases) together with the novel techniques for extracting geolocation from various data formats (e.g., textual documents and images). It also scrutinizes different ways of using these data, varying from mapping the spatial distribution of social and political phenomena to investigating the use of geotag data for cultural practices’ digitization to exploring the use of geoweb for narrating individual and collective identities online.

An earthquake occurred at Van City on 23 October 2011 at 13:41 local time. The magnitude, moment magnitude and depth of earthquake were respectively MI:6.7, Mw:7.0 and 19.07 km. Van city centre and its surrounding villages were affected from this destructive earthquake. Many buildings were ruined and approximately 600 people died. Acquisition and use of geospatial data is very important and crucial for the management of such kind of natural disasters. In this paper, the role of national and international geospatial data in the management of Van earthquake is investigated.. With an international collaboration with Charter, pre and post-earthquake satellite images were acquired in 24 hours following the Earthquake. Also General Command of Mapping (GCM), the national mapping agency of Turkey, produced the high resolution multispectral orthophotos of the region. Charter presented the orthophotos through 26&ndash;28 October 2012. Just after the earthquake with a quick reaction, GCM made the flight planning of the 1296 km<sup>2</sup> disaster area to acquire aerial photos. The aerial photos were acquired on 24 October 2012 (one day after the earthquake) by UltraCamX large format digital aerial camera. 152 images were taken with 30 cm ground sample distance (GSD) by %30 sidelap and %60 overlap. In the evening of same flight day, orthophotos were produced without ground control points by direct georeferencing and GCM supplied the orthophotos to the disaster management authorities. Also 45 cm GSD archive orthophotos, acquired in 2010, were used as a reference in order to find out the effects of the disaster. The subjects written here do not represent the ideas of Turkish Armed Forces.

Due to the current situation, and preventive measures taken to tackle COVID-19, it is crucial to keep society well-informed. Besides media and official news, that often include tabular data, it has also become a new standard for information sources to incorporate a map application or geovisualization. This paper offers a comprehensive and systematic overview describing the most prominent and useful map applications and map visualizations. News outlets should place the same importance on data analysis and interpretation as they place on data visualization. This paper emphasizes the role of geospatial data and analysis during the COVID-19 pandemic and aims to provide insights into the topic in order to better understand the consequences caused by the disease. Specifically, the paper deals with the COVID-19 Community Mobility Reports dataset, offering unique information about changes in human activity due to the pandemic. We show how this dataset can be utilized in terms of geovisual analytics and clustering in order to reveal the spatial pattern of such changes in human behavior.

Interactive 3D

Interactive 3D visualizations of geospatial data are currently available and popular through various applications such as Google EarthTM and others. Several studies have focused on user performance with 3D maps, but static 3D maps were mostly used as stimuli. The main objective of this paper was to identify differences between interactive and static 3D maps. We also explored the role of different tasks and inter-individual differences of map users. In the experimental study, we analyzed effectiveness, efficiency, and subjective preferences, when working with static and interactive 3D maps. The study included 76 participants and used a within-subjects design. Experimental testing was performed using our own testing tool 3DmoveR 2.0, which was based on a user logging method and open web technologies. We demonstrated statistically significant differences between interactive and static 3D maps in effectiveness, efficiency, and subjective preferences. Interactivity influenced the results mainly in ‘spatial understanding’ and ‘combined’ tasks. From the identified differences, we concluded that the results of the user studies with static 3D maps as stimuli could not be transferred to interactive 3D visualizations or virtual reality.

For many years FIG, the International Association of Surveyors, has been trying to bridge the gap between surveyors and the geospatial society as a whole, with the geospatial industries in particular. Traditionally the surveying profession contributed to the good of society by creating and maintaining highly precise and accurate geospatial data bases, based on an in-depth knowledge of spatial reference frameworks. Furthermore in many countries surveyors may be entitled to make decisions about land divisions and boundaries. By managing information spatially surveyors today develop into the role of geo-data managers, the longer the more. Job assignments in this context include data entry management, data and process quality management, design of formal and informal systems, information management, consultancy, land management, all that in close cooperation with many different stakeholders. Future tasks will include the integration of geospatial information into e-government and e-commerce systems. The list of professional tasks underpins the capabilities of surveyors to contribute to a high quality geospatial data and information management. In that way modern surveyors support the needs of a geo-spatial society. The paper discusses several approaches to define the role of the surveyor within the modern geospatial society.

Achieving universal access to electricity is a development challenge many countries are currently battling with. The advancement of information technology has, among others, vastly improved the availability of geographic data and information. That, in turn, has had a considerable impact on tracking progress as well as better informing decision making in the field of electrification. This paper provides an overview of open access geospatial data and GIS based electrification models aiming to support SDG7, while discussing their role in answering difficult policy questions. Upon those, an updated version of the Open Source Spatial Electrification Toolkit (OnSSET-2018) is introduced and tested against the case study of Malawi. At a cost of $1.83 billion the baseline scenario indicates that off-grid PV is the least cost electrification option for 67.4% Malawians, while grid extension can connect about 32.6% of population in 2030. Sensitivity analysis however, indicates that the electricity demand projection determines significantly both the least cost technology mix and the investment required, with the latter ranging between $1.65–7.78 billion.

Expansion or establishment of new regions (Provinces, Regencies/Cities) is a consequence of the politics of decentralization implemented in Indonesia. The development of decentralization in Indonesia underwent fundamental changes after the reformation in 1998. Inception of UU No 22 tahun 1999 concerning regional government has given a new color to the administration of government in Indonesia or what is called broad autonomy. Restructuring regional governments that provide discretion in the form of broader authority in running their government in accordance with regional needs has created many implications for the region, one of which is stretching and the spirit of the region to bloom. In determining the boundaries of forming new regions, the geospatial aspect is an important and strategic aspect. Problems related to geospatial aspects such as maps of regional boundaries, area size, etc are issues that need to be clearly defined and calculated in the new (autonomous) regional (Province, Regency/City) determination. But in fact the law on the formation or establishment of regions in the period 1950-1999 on the geospatial aspect did not become an important part so that it caused problems later which could potentially trigger social conflicts such as regional boundary disputes. Post-reformation, the development of the role of the geospatial aspects has evolved a little more advanced, such as the existence of regional boundary maps in the appendix to the law on the formation or expansion of new regions, such as UU No 7 tahun 2002, UU No 2 tahun 2003, and others. However, there is still something that must be evaluated regarding the map in the attachment to be in accordance with the geospatial rules. A very progressive development in terms of the geospatial aspect is in UU No 20 tahun 2012 concerning the formation of the Kalimantan Utara province that utilizes geospatial data properly
