All rights saved. Dynamic Databases of advanced spatial information present a basic piece of the order and control frameworks in crisis frameworks (e. G. , the Integrated Emergency System, the Medical Rescue Service). Information for these databases doesn't really need to originate from a solitary source. They can be procured from different spatial databases; they can have diverse geometric, topological, or topical properties that can be moved into a specific database. The subsequent database must be harmonicas so that the client would have the option to utilize it as a homogeneous database evaluating unambiguously recognized geometry, topology, and topical data. The point of the paper is to educate about another venture which proposes a general technique of harmonistic spatial databases for the order and control frameworks and to make the numerical models for that system.

PH/P-lets 1 . : Current Situation in Knowledge of the Spatial Data Harmonistic Problems 1. 1 . Harmonistic of spatial information There are generally immense regionally restricted databases in the Czech Republic utilized in various branches. Essential databases are made by the administration organization (the Czech Office for Surveying, Mapping and Caster CLC. KHZ and the Army of the Czech Republic CAR) and they are proposed for exercises related with the elements of the state (Taleteller, Hookahs, Hofmann, Achromatic, 2009). These databases completely spread the region of the Czech Republic, they are made by the mandatory standards and they are persistently refreshed. These guidelines depend on both the first national norms and the global measures, particularly the Open Spatial Consortium (COG) proposal in the Infrastructure for Spatial Information in Europe (INSPIRE) structure (if there should be an occurrence of the CLC. KHZ and the Ministry of Agriculture) and the Defense Spatial Information Working Group (SWIG) norms (in the event of the Ministry of Defense MOD). Aside from these essential databases, different databases particularly topical are made in the Czech Republic, for instance databases of soil types or databases from the fields of topography, ranger service, vitality, scene assurance, relaxation exercises, and so on. Both the administration organization bodies and business associations have duty regarding these databases. Harmonistic is tended to by and large in the Czech specialized standard CNN ISO 860, notwithstanding, its genuine effect on the issues of computerized spatial information is errantly not tended to sufficiently neither on the national nor global levels. It is conceivable to utilize huge numbers of the previously mentioned databases as the source base for dynamic procedures in the order and control frameworks of either the salvage administration or the military. Source information can be utilized not just for a straightforward direction in the territory yet additionally for comprehending assignments identified with specific choices, for example, huge activities of the crisis administration parts, military danger to the nation, expectation of the scene changes during outrageous climate conditions or modern mishaps, etc. There are numerous errands where the source information are joined with one another and new information are made by applying numerically characterized methodology (Taleteller, Balsa, Racer, Hofmann, Hookahs-Markova, 2012),. Such frameworks may utilize information originating from different sources. Information sources can shape a piece of the framework or they can be appended to it just for the term of a specific errand. All things considered, the information must be orchestrate either forever or briefly so that a homogeneous database is set up for a specific undertaking or a specific arrangement. The properties of this database are then completely reflected in explaining he supporting assignments serving for the dynamic procedures. Those properties influence additionally the quality and dependability of the choices. Numerous associations are occupied with the procedure of information harmonistic and information the Multinational Spatial Copulation Program (MAGIC) venture (http://enchantment. HTML), Forerunner Institute for Computer Graphics (http://wry. Invigorated. Eh/home. HTML), and so forth 1. 2. Methods of explaining harmonistic As the essential drivers of the heterogeneity of spatial information the accompanying issues are commonly thought of: the distinctions in meaning of theoretical models being based n different authentic and momentum principles; the understanding of reasonable models for a specific domain and a specific circumstance; utilization of various facilitate frameworks and diverse guide projections; applying various procedures for information altering and investigation (Arabians, 2009; Arabians Vela, 2010). The genuine harmonistic comprises in associating the theoretical models, I. E. N bringing together meanings of items and marvels, their coding and unification of their geometric, topological, and topical properties. For this, it is conceivable to utilize information word references of the Thesaurus type. Unification of information 542 slender a homogeneous information condition is the following stage where the fundamental database is considered as reference and other information sources are being associated with it regarding the given guidelines and techniques. The total arrangement of harmonistic and making of a homogeneous database can be acknowledged either specially appointed or with the assistance of arranged formalized apparatuses or projects (Fighting et al. 2011; Ghana Godchild, 2002). Harmonistic process modifies the properties of a last homogeneous database which is important to be viewed as when utilizing this database, particularly in dynamic and controlling procedures. On the off chance that the homogeneous database is utilized for spatial examination as a base of dynamic procedures then the investigation results are impressively impacted by these properties. Accordingly, it is important to portray these properties and to consider in the order and control process. 2. Venture Principles, Goals and Methods 2. 1. Undertaking standards The crucial target of the task is to plan a perplexing framework for harmonistic the heterogeneous spatial information acquired from different sources such that the homogeneous database is utilized in the order and control frameworks. The fundamental databases gave by state associations (standard information sources) will be utilized as the essential sources. The information originating from the universal undertakings, for example, INSPIRE, MAGIC, or Vamp will be considered as the auxiliary sources. Just the global information sources expected to frame a critical piece of information will be utilized. The crude information gave by the remote detecting sensors including symbolism gained utilizing non-metric cameras will be considered as advantageous sources. The associations geometric, topological, and topical between all wellsprings of information numerical strategies to portray them unambiguously and to build up fragrance methodology of information harmonistic. Additionally the inward attributes of homogeneous information will be considered, particularly their spatial and topical exactness and sureness, and further, the impact of these internal qualities on dependability of dynamic if these choices will be founded on spatial examinations. . 2. Venture objectives The objective of the proposed venture is to plan a general technique of harmonistic of spatial databases for order and control frameworks. The sub objectives are the accompanying: Analysis of properties of spatial information originating from existing assets with deference o their semantics, geometry, topics, structure an d methods of its arrangement. The investigation will cover both the standard items and the results of non-standard strategies, for example, diagonal symbolism gained by remote detecting techniques. 2. Examination of impact of spatial information properties on the calculated plan of a reference database; semantic meaning of put away highlights and wonders; and their geometric, topological, and topical properties. 3. Modernization of the previously mentioned impacts and making of scientific models and their formalization in a proper situation so the database boisterous be homogeneous for the utilization in the order and control frameworks. 4. Use of numerical models for an evaluation of nature of harmonicas and homogeneous database concerning the run of the mill assignments utilized in the order and control frameworks. 43 5. Research of an unpredictable impact of the homogeneous database on arrangement of expository spatial undertakings on the side of order and control, and furthermore on dependability of 6. Confirmation of the proposed techniques and models in managing spatial help of emergency the board with an attention on cartographic representation of an emergency circumstance heavenly attendant; on advancement of salvage vehicles transportation both on courses and in the landscape; on perception of departure systems, and so forth 2. 3. Undertaking techniques Necessary investigation of non-homogeneity sources in essential information will be acted in the main phase of the task. These will be particularly sources worked by state specialists and associations, and furthermore sources utilized as per global understandings and collaboration. Examination of sources that might be gotten from participating associations will follow. Geometric, topological, and semantic non-homogeneity will be analyzed inside the investigations and their causes (e. G. Insane standards of information assortment, geographic nature of articles and marvels) will be resolved.
