GIS technology changed the way cities are planned. Software suite like ArcGIS supports complex large data analysis, simulations and management. At the Department of Architecture and Urban Planning in Novi Sad students learn how to integrate their knowledge about urban planning and architecture by using several essential components of ArcGIS.In this paper various approaches in spatial and data analysis based on GIS technology are introduced. Also several student work case studies are presented. Temporal change of urban morphology through graphs and animations and spatial analysis of present urban structure are two major topics presented in this work.
An internet-based land
valuation system is being developed to replace the scientifically obsolete
Hungarian land valuation system, the so-called AK (“Gold Crown”) ratings. The
new system is supported by a GIS and it is unique in its capability of
providing an up-to-date index of soil quality and land value. The geographical
information is provided by national map databases on genetic soil maps and soil
attributes at the scale of 1:10.000, combined with cadastral maps, digital
terrain model, topographic map, orthophotos of aerial photographs and agronomic
field records. The automated algorithms are easy to update, can be made legally
binding and can provide a transparent system for land taxation, calculation of
subsidies, appropriation. Given that detailed (1:10,000 or finer) soil map
coverage will be completed for all lands of Hungary (at date only 60% of the
croplands have soil maps), this way a multifunctional system will be available
that promotes an optimum use of land resources.

Methods for georeferencing and GIS applications of the maps and plans from the 16th century until 1990 are described. The results of georeferencing — derivatives of historical maps, show a high value and potential of usability for the studies of urban areas — for historical issues, and for more comprehensive planning solutions allowing better development and policy. The applicability of the georeferenced historical maps was explored according to time series analysis. The studied were the applications for the urban area of Ljubljana, Slovenia case study: observing the continuous changing of the river course of Ljubljanica river and railway network.
GIS adaptation and digital reambulation of large-scale soil information
originating from various agrogeological surveys has become a key issue in
Hungary due the recent challenges. The
national programme initiated by L. Kreybig for the systematic, 1:25,000 scale
practical soil mapping of Hungary was carried out between 1935 and 1951, and
provided detailed soil information (1:25,000 scale maps and complementary
database in the form of explanatory booklets) for the whole country. Later farm
level (1:10,000 scale) soil surveys fulfilled the practical requirements of
Hungarian agriculture, producing a huge quantity of map based, soil related
archives still represent a valuable
treasure of soil information at present. Their digital reambulation and GIS adaptation
is a challenging task, which was initiated by RISSAC GIS Lab in co-operation
with various institutions. The aim of these activities is the development of
large-scale soil modules of a Hungarian production database for the
determination of the optimal functions of agriculture in a given region,
together with the harmonization of agricultural production and the protection
of land and environment.
In the densely populated part of Nagytétény bay Metallochemia factory has been operating as a pollution source resulting from stack emission as early as since the beginning of the 1900's. The nearby residential properties were impacted by significant concentrations of heavy metals, which found their way also to the deeper strata of the soil. Our task was to perform the detailed environmental state investigation of the nearly 1,400 impacted properties located in an area of 3.5 km2 and to prepare a technical remediation action plan. For the execution of the task a complex GIS system was developed, to take the numerous design aspects (such as technological and horticultural condition of the objects on the properties, presence of public utilities, current and planned land use, percentage of built-up area, archaeological, cultural, protected natural and other restricted areas, objects, and morphologies, as well as pedological, geological and hydro-geological conditions) into consideration. For the work three series of aerial photographs, taken at different times, and approximately 20 thematic maps with different scales and projections had to be integrated into the system. Data processing was executed by ArcView GIS programme. This system made us possible to manage and evaluate the territorial relationships between the data, as well as to make design calculations, and to thematically represent the results by using previously developed logical functions. On the basis of the design considerations, environmental technical and horticultural remediation action plans were developed for each property. This study presents the main steps of fieldwork and the building of the GIS system without analysis of the collected data.
The survey results of the MÉTA program are managed with centralised relational database management system (MS SQL 2000) developed and set up in a local area network. Besides the MÉTA database server, a publishing server, an archiving server and a GIS workstation were applied. The core information entities of the MÉTA database are: information subproject, MÉTA quadrate, MÉTA hexagon, (semi-)natural habitat, potential vegetation with numerous habitats, landscape ecology and land use attributes, and surveyor. This information is coded in the nine main tables of the normalised database. In the recent state there are almost 1,500,000 records in the main tables that are managed in 241 independent fields. The published version of the MÉTA database supports the query service, and handles this information in 7 denormalised main tables. This much more redundant version is 11 GB in size. The 20.6% (179 man-month) of the human resources in the MÉTA program were devoted to the information tasks (set up and preparation, MÉTA database and information system development, replenishment and quality assessment, MÉTA query, GIS and printing services) between 2002 and 2007. The basic structure of the MÉTA database version 1.2 is finalised and the main functions regarding data processing have been developed. The accomplishment is higher than 90%, quality assessment is under way, while scientific verification and data harmonisation are started. The area of (semi-)natural and degraded vegetation of Hungary is estimated to 1,800,000 hectares (19.4% of the country) of which the natural, semi-natural is about 1,200,000 hectares (12.9% of the country). All of these are highly fragmented and unevenly distributed over the country. It is shown by several basic figures, professional content and quality measure facts of the database. There is also a fact sheet of surveyors that shapes the important characters of their field experience profile, too.
