For the planning and sustainable development of large cities, it is critical to accurately locate and map, in 3D, existing underground utility networks (UUN) such as pipelines, cables, ducts, and channels. An emerging non-invasive instrument for collecting underground data such as UUN is the ground-penetrating radar (GPR). Although its capabilities, handling GPR and extracting relevant information from its data are not trivial tasks. For instance, both GPR and its complimentary software stack provide very few capabilities to co-visualize GPR collected data and other sources of spatial data such as orthophotography, DEM or road maps. Furthermore, the GPR interface lacks functionalities for adding annotation, editing geometric objects or querying attributes. A new approach to support GPR survey is proposed in this paper. This approach is based on the integration of multiple sources of geospatial datasets and the use of a Web-GIS system and relevant functionalities adapted to interoperable GPR data acquisition. The Web-GIS is developed as an improved module in an existing platform called GVX. The GVX-GPR module provides an interactive visualization of multiple layers of structured spatial data, including GPR profiles. This module offers new features when compared to traditional GPR surveys such as geo-annotated points of interest for identifying spatial clues in the GPR profiles, integration of city contextual data, high definition drone and satellite pictures, as-built, and more. The paper explains the engineering approach used to design and develop the Web GIS and tests for this survey approach, mapping and recording UUN as part of 3D city model.

A Mashup is the process of merging multiple sources of data, both spatial and non-spatial, into a single integrated spatial display. It is about extracting spatial data from a non-spatial source and combining with other spatial data and finally displaying it on a map. Mashups can potentially combine any type of contents and functions over the web, regardless of whether a formal interface of programming is available (Fu et al., 2011). The present study discusses the basic architecture of the Geospatial Mashups in Web GIS and its application in tourism promotion.

The chapter presents examples of applications and study cases of platforms of geospatial decision support systems for national public policies and strategies. The rapid progress of internet with the combination of GIS has paved the ways for web distribution of spatial data. Users can access the spatial data through a Web-GIS website, make thematic maps, and perform all types of spatial queries and analysis. In the context of an increasing emphasis on decentralized planning, the need for collection and dissemination of data at local levels has been increased. Use of the web as a dissemination medium of geographic data in the form of interactive maps can be regarded as a major advancement in digital cartography and opens many new opportunities, such as real-time maps, cheaper dissemination, and decentralized sharing of geographic information.

The article discusses possibilities of geochronological tracking technology for studying the spatial mobility of social groups in Russia in the past. The GIS proposed is necessary to visualize and analyze spatial data in a prosopographic research of about 400 szlachta representatives in Peter’s Epoch. Spatial mobility is understood as the intensity of person's translocation through settlements and his ability to respond to external challenges by moving. The archival materials of the Senate inspection of the szlachta (1721-1723) served the basis for the study and the resource formation. Particular attention is paid to the design of software research tools – the PostgreSQL database and the web GIS based on the latter. It is the first time when geochronological tracking as a geoinformatics method was used to prosopographically study the Russian nobility. The methods of historical source spatial data representation and visualization are implemented in the form of a geodatabase that is publicly available. Two program modules (the GIS among them) grant a wide range of Internet users an access to historical sources text data as well as synchronically visualized data on the szlachta service under Peter the first.  The authors conclude that it is promising to create a special web interface which provides users with flexible text and geodata filtering and analysis. The web project created can be used both for research in the field of social history, historical geography, genealogy and for educational purposes in such courses as “historical computer science” and “digital humanities”.

The design of a Web-geographical information system strongly requires methodological and operational tools to deal with information distributed in multiple, autonomous and heterogeneous data sources, and a uniform data publishing methodology and policy over Internet web sites. In this chapter, we describe our experience for the activities of requirement analysis and conceptual design of the DEAFIN Web-geographical information system whose objective is to improve the quality and the comparability of information about available industrial vacant sites, coming from different regional data sources. Heterogeneity and web availability requirements have been taken into account in the system architecture design. The DEAFIN system is thus conceived as a federated web-based information system, capable of managing and providing access to all the regional relevant information in an integrated and complete fashion. Furthermore, since the data available by a given DEAFIN region partner can be both spatial data and alphanumeric data, for each regional component system in the DEAFIN system, a Web-GIS system is defined.

With the implementation specification of the Web Processing Service (WPS), a standard to process spatial data on the web is available from the Open Geospatial Consortium (OGC). This new possibility in web-based information systems allow an interoperable processing of different data based on service-oriented architectures. This paper describes requirements and an implementation for web-based processing and workflow creation to generate and provide remote sensing products like fire hotspot points and land surface temperatures based on NASA MODIS data. Therefore, a WPS as well as service chains to process these remote sensing products are implemented. PyWPS is used as WPS and tested with focus on processing remote sensing data. To chain the developed processes, software like 52° North Orchestration Engine, Apache ODE and internal software for executing processing chains and providing a workflow as WPS process are tested. A Web-GIS with open-source software was developed to manage started and finished processes, to search for available satellite data and to create processing chains interactively. An interface to retrieve and process archived data was integrated; the user of this system can search interactively for archived satellite data and process it with the developed processing services and workflows. The Web-GIS also acts as a WPS client, client for visualizing processed data and creator as well as security layer for processing chains. These developments and research work show that there is additional work to improve the WPS specification for example by adding domain-specific profiles for working with large raster data to define standardised rules for data-exchange between the processes. In the field of process orchestration, no standardised data format describing processing chains exists yet.

Abstract Using maps is inevitable in many human activities as well as in mountaineering. Until recently, most of the spatial and attribute data of the mountaineer’s interest could have been found only in analog form. With the development of information technology, global navigation satellite systems (GNSS), easily accessible measuring sensors and digital cameras, it is easier to collect, store, visualize, share, and update spatial data. The web GIS with its associated applications assumes dominance in browsing and dissemination of spatial data, and is applied in areas where there is a need for processing, analysis and visualization of various data that contain a spatial component, including mountaineering. When planning hiking, mountaineers need both spatial and attribute information on mountaineering facilities, checkpoints, and hiking trails in the form of GNSS traces. Through the interactive web application interface, it is possible to connect all these data, enabling easy viewing, browsing and analysis, or performing various spatial queries, which greatly facilitates the planning of hiking excursions. This paper presents a review and comparison of four most visited Croatian mountaineering portals: HPS’s Interactive Mountaineering Map of Croatia, Mountaineering portal and Geodetic mountaineering portal developed at the Faculty of Geodesy of the University of Zagreb and planinarenje.hr portal developed by the group of mountain enthusiasts. Numerous data on Croatian mountains and peaks, mountain facilities, huts and hiking trails are now accessible through portals to anyone with Internet connection, either with the computers, tablets or smartphones. All users can browse, filter and download data from the portal, and there are additional options for authorized users such as commenting on portal content. Several thematic portals of neighboring countries were also analyzed (portal of the Slovenian Mountaineering Association, Slovak mountaineering portal and one Swiss mountaineering portal) and compared with Croatian portals. Finally, the importance of the web GIS portals for the development of mountaineering tourism was emphasized, as well as the ecological culture and the sustainability of the mountaineering environment (preservation of mountain trails and facilities, protection of endemic plants, karst and geological features, etc.). Highlights for public administration, management and planning: • The presented web GIS represent an effective and efficient tool for planning and conducting trips in mountain areas as it allows better organization and management of mountain content for the tourists and other hikers. • Registered users can participate in the portal update (e.g. peak or hill endonyms) and this can be used by State Geodetic Administration for their register of geographical names (http://rgi.dgu.hr/pretrazivanje) • The Web GIS can also be used as a support in the tourism development of local mountain areas with respect to the ecological culture and sustainability of the mountain environment.

In this paper, a developed low-cost system is described, which aims to facilitate 3D documentation fast and reliably by acquiring the necessary data in outdoor environment for the 3D documentation of façades especially in the case of very narrow streets. In particular, it provides a viable solution for buildings up to 8-10m high and streets as narrow as 2m or even less. In cases like that, it is practically impossible or highly time-consuming to acquire images in a conventional way. This practice would lead to a huge number of images and long processing times. The developed system was tested in the narrow streets of a medieval village on the Greek island of Chios. There, in order to by-pass the problem of short taking distances, it was thought to use high definition action cameras together with a 360˚ camera, which are usually provided with very wide-angle lenses and are capable of acquiring images, of high definition, are rather cheap and, most importantly, extremely light. Results suggest that the system can perform fast 3D data acquisition adequate for deliverables of high quality.
