Atlas Server ?
A Tool for Atlas Mapping
Public Fund Altai 21-st Century
Barnaul, Russia
Territorial Information Systems
PURPOSE OF THE WORK
Development of a server tool focusing on
atlas mapping and facilitating creating and
viewing complex maps in the distributed
territorial information systems
WORK AREA
Geographic information technologies in the distributed
systems.
An architecture of distributed GIS applications.
KEY CONCEPTS
Atlas mapping, Territorial Information Systems, Applied
GIS Services, Atlas Server.
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
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 Systems
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.
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.

THEMATIC ATLAS MODEL
APPLIED ATLAS-SERVICE
An applied Atlas service of the territorial
information system is a program component,
providing functionality of a thematic atlas and not
including map presentation.
