Abstract: Cartographic data represents the main and basic component of a Spatial Data Infrastructure. SDI, in turn, has the role of supporting, with strategic information, the most diverse political and economic actions, in the management and planning of public actions. Thus, this work aims, initially, to present an overview of cartography in Brazil through the analysis of the evolution of topographic mapping coverage in the country. For each of the main scales used, a coverage map was created. The analyzes reflect three different periods (until 1997, between 1998 and 2007, after 2008) in order to relate how and to what degree, the creation of Brazilian National SDI (in 2008) had an impact on the mapping production in the country. Given the current panorama, as a final objective, this paper aims at to present proposals to leverage the coverage of this reference data. One of them is the use of new data sources such as Volunteered Geographic Information, especially in areas with outdated mapping or without mapping, as has already been used in some countries. Another proposition is to share the responsibility of mapping through partnerships with other levels of government, which would result the decentralization and the optimization of cartographic production.

This chapter discusses the role of Open Geospatial Consortium (OGC) geospatial standards as a key aspect in the development, deployment, and use of Geospatial Web Services. The OGC vision for web services is the complete integration of geographic (location) and time information into the very fabric of both the internet and the web. Today, the Geospatial Web Services encompasses applications ranging from as simple as geo-tagging a photograph to mobile driving directions to sophisticated spatial data infrastructure portal applications orchestrating workflows for complex scientific modeling applications. In all of these applications, location and usually time are required information elements. In many of these applications, standards are the “glue” that allow the easy and seamless integration of location and time in applications - whether simple mass market or integration into enterprise workflows. These standards may be very lightweight, such as GeoRSS, or more sophisticated such as the OGC Web Feature Service (WFS) and Geography Markup Language (GML).

AbstractExchange of and access to spatial data is the principal goal of any Spatial Data Infrastructure, therefore, one of the key concepts of SDI is interoperability, especially semantic and syntactic. Whereas application schemas and quality issues are one of the aspects that have to be considered to ensure a successful data interchange in SDI.Two types of application schema are widely used in the European SDI as well as in the Polish SDI. They cover both semantic and syntactic interoperability and are an integral parts of spatial data specifications and relevant regulations in the form of data models. However, working out accurate and correct application schemas may be a challenge.Additionally, faulty or too complex application schemas can influence the ability for valid data interchange, and consequently, prevent achieving interoperability within SDI. Therefore, the capability to examine and estimate the UML and GML application schemas quality seems to be a worthwhile and important issue in the context of semantic and syntactic interoperability in SDI.The main subject of this article it to set out the context of performed studies, among others, the role of application schema in the interoperable data exchange, issues related to the concept of quality and its measures.

The article proposes a new development concept of topographic mapping in Ukraine. The goal. It is based on the implementation of a new system model that responds to the geoinformation approach to topographic mapping in the development of National Spatial Data Infrastructure (NSDI) and provides the creation of geospatial data sets in the form of databases and knowledge bases based on existing standards and specifications: series of International Standards ISO 19100 “Geographic information/Geomatics”, Open Geospatial Consortium (OGS), INSPIRE, National Standards of Ukraine (DSTU), Complex of Standards Organization of Ukraine (SOU) “Topographic database”. Methods. The basis for the research is the analysis of the possibilities of applying the theory of databases and knowledge bases International Standards and specifications. Scientific novelty and practical significance. It provides a high intellectual level of Core Reference and profile geospatial data, which is capable to provide geoinformation analysis and modeling in modern GIS. In addition, the implementation the infrastructure approach to topographic production and the creation and development of a permanent topographic monitoring system will ensure the publication of geospatial data in real time, almost simultaneously with changes in the terrain, which guarantees the maintenance of the single digital topographic basis and, accordingly, Core Reference Datasets for NSDI.

The information about regular XXVI Congress of the International Federation of Surveyors (FIG) 2018 hold in May 2018 in Istanbul (Turkey) is given. The article contains a brief summary of the Congress’ scientific program, which was implemented in the framework of 4 Plenary sessions, 63 technical meetings in sections, the Forum of FIG Director Generals, 15 meeting sections of FIG, 10 meetings of the commissions, 11 meetings with partners of the World Bank, UN-population/GLTN and FAO, 3 sections of Platinum sponsors of the Congress (ESRI, Leica Geosystems, Trimble) and other sessions and meetings. Provided information about the technical exhibition, which had presented 50 firms. The main development trends of science, production and education in the field of Geodesy, Cartography, Cadastre and Spatial data infrastructure are summarized. The work of FIG Director Generals’ Forum was focused at the role of national geospatial agencies at present and in future. Three reports from developed European agencies focused at modern digital economy matters were made.

Spatial data are increasingly being used for a range of applications beyond their, traditional uses. Collection of such data and their update constitute a substantial part of the total costs for their maintenance. In order to ensure sustainable development in the area of geographic information systems, efficient data custody and coordination mechanisms for data sharing must be put in place. This paper shows the importance of reference data as a basis for national spatial data infrastructure that serves as a platform for decision making processes in society. There are several European initiatives supporting the wider use of spatial data. An example is the INSPIRE Directive. Its principles and the main world trends in data integration pave the way to successful SDI driven by stakeholders and coordinated by national mapping agencies.

The article deals with the role of satellite images bank creation for the Altai Republic region for the purpose of monitoring the results application of particularly protected natural territories. Absence of access to relevant spatial data, concerning the analysis of processes in the protected woodlands, reserves and natural parks makes it necessary to choose reliable information resources. The applications of open data sources is offered. The surveys of natural and technical parameters, that should be taken into account in choosing images on geoportals such as the spectral set of channels, availability of cloud and snow cover and seasonal aspects, are suggested. Some recommendations concerning the establishment of mosaic composites on the basis of multi-temporal images surveys result are offered in order to obtain the most uniform images results distribution with minimum noticeable stitching lines and distinction in brightness/contrast parameters of images in each spectral channel.
