Topographic databases and general geographic maps are essential components of geographic information systems and the primary and rich spatial information source at general scales. The article presents qualitative and quantitative analyses based on the content of general geographic maps and topographic databases carried out on the example of products of selected national mapping agencies (NMAs). This research aims to verify whether the data contained in the analyzed databases and the information presented on general maps constitute the rich source of geographical and spatial information, as well as to examine how the analyzed General Geographic Objects Database (BDOO) developed in Poland differs from the selected databases of similar level of details. The results of qualitative and quantitative analyses are presented in comprehensive charts and tables, which show the obtained results in a synthetic and complex manner.

Mapping Technology

Android, Geographic Information Systems, RESTful, Web One of the mapping technologies widely used today is Geographic Information Systems. Geographic Information Systems (GEOGRAPHIC INFORMATION SYSTEMS) is a mapping technology in the form of computer-based information systems, designed to work using data that has spatial information or spatial reference. Mapping technology is widely used to facilitate human work. In this research, Geographic Information System technology was used to support one of the business processes at the Bandar Lampung City Tourism Office. This system was built to assist related agencies in recording tourist sites. The system consists of a web-based system and Android-based applications that are connected using RESTful Web Service. The system is implemented using the PHP programming language with the help of CodeIgniter for web-based systems, and the Java programming language for Android-based applications. The method of developing the system used is the waterfall model method according to Rossa U.S. and Saladin (2014). Application design is based on Unified Modeling Language (UML), flowchart diagrams, and interface design. While the application used in the creation of the Android base system is Android Studio. The testing method used is the system's functional Black-Box. The results of black-box testing data show that the system runs as it should, the system is easy to understand by users, and can meet the functional needs of the system needed by the Bandar Lampung City Tourism Office

The emergence of technological systems with computerized cartographic application allowed the resolution of certain military problems between the 1950s and 1960s. The first GIS was created in Canada Geographic Information Systems in 1964 for Tomlinson. At this time, GIS was in a consolidation phase in multiple areas and for various purposes. The geographical science growth with the development of GIS were in connection to the subject of the new geography, justified by the application of the methods of quantitative analysis in various spatial nature of research. In this context, the GIS feature a number of operational advantages and have allowed the proliferation of new fields of endeavor in open access systems across multiple forms of acquisition, management, interpretation, and spatial information analysis. The main goal of this chapter is to underwrite the concept of GIS, as well as distinguish the diversity of applications from the past until the present, and to identify new paths to accommodate recent scientific approaches with extensive range of application possibilities.

Abstract. In this work, we propose a dynamic, flexible and interactive urban digital terrain platform with spatial data and query processing capabilities of geographic information systems, multimedia database functionality and graphical modeling infrastructure. A new data element, called Geo-Node, which stores image, spatial data and 3-D CAD objects is developed using an efficient data structure. The system effectively handles data transfer of Geo-Nodes between main memory and secondary storage with an optimized directional replacement policy (DRP) based buffer management scheme. Polyhedron structures are used in digital surface modeling and smoothing process is performed by interpolation. The experimental results show that our framework achieves high performance and works effectively with urban scenes independent from the amount of spatial data and image size. The proposed platform may contribute to the development of various applications such as Web GIS systems based on 3-D graphics standards (e.g., X3-D and VRML) and services which integrate multi-dimensional spatial information and satellite/aerial imagery.

Gis Applications

Geographic information systems (GIS) refers to the computer hardware and software that supports the management and analysis of spatial information. There has been a recent increase in the development of Internet accessible GIS applications, called Web- GIS (Al-Kodmany, 2001; Carver, Evans, Kingston, & Turton, 2000). Web-GIS facilitates participation among stakeholders through disseminating user interfaces for storing, accessing, and analyzing spatial information using the Internet (Al-Kodmany, 2001; Carver et al., 2000; Dragicevic & Balram, 2004). Participatory and community GIS approaches focus on system design that supports collaboration among organizations serving and representing interests of many constituent groups, including nontechnical users (Carver, 2003; Craig, Harris, & Weiner, 2002; Drew, 2003; Elwood & Ghose, 2004; Elwood & Leitner, 2003; Ghose, 2005; Ghose& Elwood, 2003; Kyem, 2004; Seiber, 2003).

Over Time

Modern geographic information systems provide great opportunities for using a variety of data on spatial objects, searching and storing materials in a convenient form. The authors describe the experience of creating a spatial river-database of Mordovia Republic, RF in a GIS environment based on the reference manual “Hydrological knowledge”. Various approaches to solving the task were tried. The assessment of the temporal reliability of the data was carried out, since over time a number of water-bodies’ names became outdated; the river network had undergone changes due to natural reasons and under the influence of economic activity. The created database of streams of Mordovia can be used as a reference and information source.

This chapter applies the proposed methodology to the working dataset of 67 wrecks. Varied quantitative analyses serve to contextualize spatial and diachronic trends in the study area against the broad backdrop of the east and Mediterranean as a whole. Two discrete peaks of activity provide the basis for constructing comparative Social Network Analysis visualizations of Roman and Late Antique connections within and among the geographical areas represented by cargos. The analytical tools of Geographic Information Systems, together with environmental parameters and seafaring capabilities, allow these network links to be grounded spatially using likely sailing times; such journey lengths reflect the “costs”—and therefore the potential regularity and investment—represented by these connections.
