Development of a server tool focusing on atlas mapping and facilitating creating and viewing complex maps in the distributed territorial information systems PURPOSE OF THE WORK
WORK AREA Atlas mapping, Territorial Information Systems, Applied GIS Services, Atlas Server. Geographic information technologies in the distributed systems. An architecture of distributed GIS applications. KEY CONCEPTS
TASKS OF THE WORK 1. Defining specific functionality of geographic information technologies used in the territorial information systems. 2. Analyzing existing technologies providing mapping functionality in the territorial information systems. 3. Development of Applied GIS Services for Atlas mapping. 4. Designing an architecture of the Atlas Server. 5. Developing the Atlas Server and creating examples of territorial information systems on its base.
Geographic Information System is a common computer technology designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information independently of the subject area. Territorial Information System (TIS) is an integrated subject – dependent computer system, based on the object model of the subject area and presenting subject–dependent methods of presentation, input, processing, analysis and output of information, including geographically referenced information. Geographic information System Territorial Information Systems
KEY PROPERTIES OF TIS 1.TIS integrates various computer technologies, including geo-information technologies. 2.TIS is designed for a non-professional user in the field of GIS and mapping. 3.TIS provides mapping interface of higher level which is a thematic atlas level and not the level of separate cartographic layers or maps.
MOST COMMON TASKS OF TIS: displaying current state of the area and all spatially distributed objects and systems of interest; location search; data aggregation on the location and spatial distribution criteria
MORE COMPLICATED TASKS OF TIS: monitoring changes of the territory or spatially distributed systems; calculating and displaying continuous attributes of the territory; optimal routes search; assessing distribution of objects of interest; zoning a territory on the base of various criteria.
MAPPING SERVICES HIERACHY A map is created in the client side from the layers transferred from GIS Server A map is created in a desktop GIS and is transferred to the client from Application server A map is created with an applied GIS service provided by Application Server
An applied Atlas service of the territorial information system is a program component, providing functionality of a thematic atlas and not including map presentation. APPLIED ATLAS-SERVICE
Traditional architecture of a distributed GIS-application An architecture of GIS-application based on Atlas Server
includes Atlas Services instead of base GIS Services consists of Atlas Services, Starting Atlas Services Component and Component Forming Map Display allows connecting new Atlas Services (openness of Atlas Server ) ATLAS SERVER PROPERTIES
OUTPUTS can be applied for a quick development of territorial information systems provides a cartographic service of atlas level provides extensibility and scalability of the created system supports a development of GIS applications on the base of DCOM and WEB protocols provides independence from base GIS constructors and visualization means Proposed Technology
