Existing pedestrian flows extend from the surrounding urban web to the redeveloping area to create a new grid, that will be used in three different scales, forming new open spaces. The materials define the subregion’s particularities. Specially modulated spaces are designed, sheltered or not, to accommodate any entertaining, athletic or other activities. Hypsometric differences allow the user to enjoy the sea view from each point of the redeveloping area. The area has been designed to be as easy as possible for use by people with disabilities.

Regional Planning Guidelines aim, first of all, to undertake measures for the protection of natural environment. A wider environmental network connects the most important areas of environmental value and outlines the interrelations with relevant neighboring areas.

The network includes pockets located in the coastal front, where intense pressure is indicated because of touristic activities.

A sustainable management of natural resources and development of rural area, is achieved through a proper exploitation of natural resources, as a result of developing alternative tourism activities, environmentally friendly, for the benefit of local communities.

* 1st Prize in Thematic Map Competition on the 6th National Conference of the Hellenic Society of Geografical Information Systems (HellasGIs) / Athens / December 2010

The criminal predisposition is a result of observation and analysis of nine variables related to marital status, labour market and wider socio-economic indicators, of E.U. countries’ population. It has to be mentioned that there is not any functional relation between the exported indicator of criminal predisposition and the primary variables.

The projection system for imaging the European continent is Lambert Conformal Conic.

Demografic Profile Comparison Between Kapodistrian and Kallikratian Municipalities Spatial Dimensions of Demographic Phenomena / group project / 2011 (spatial scale 1:5,000,000 - 1:1,000,000) * part of the study has been presented and published on the Proceedings of the 3rd National Conference of Urban Planning and Regional Development, with the title “Relations between permanent and actual population of Kallikratian Municipalities, based on the General Census of 2001” / Sep. 2012

In the first section of the study, basic demographic indicators between two spatial levels, Kapodistrian and Kallikratian Municipalities, are compared (“Kallikrates” limits municipalities from 1024 to 325). The study reffers to all Municipalities of Greece, based on 2001 General Census’ data.

In the second section, the concepts of legal, actual and permanent population are analyzed, the relations between real and permanent population of municipalities are examined and indicators are proposed based on the analysis of the three polulation types, as population sets.

Analysis of Residence Mobility at Perfecture Level (1995-2001) Location-Allocation of Spatial Functions / group project / 2011 Spatial analysis (scale 1:5,000,000)

In the study, are presented in a series of maps the absolute sizes of mobility (incoming and outgoing population) at prefecture level, the percentages on the total internal movement (country level), the location quotient of incoming population for residence per prefecture and the probability of a resident from the prefectures of Attica (A1 Athens) and Thessaloniki to move to other prefectures, according to Huff Model.

Probability of movement ( % ) 0,0 - 0,3 0,4 - 0,7 0,8 - 1,4 1,5 - 2,5 2,6 - 4,7 4,8 - 8,4

It has to be mentioned that the prefecture of Attica is divided into four districts, for the best understanding of the phenomenon, due to the high concentration of residents in this prefecture.

The largest movement is observed in prefectures around the two major urban centers of the country and the number of incoming population to Thessaloniki is larger than the number of outgoing population on the same prefecture, in contrast to prefecture of Athens A1 in Attica.

Design and Implementation of Multicriteria Spatial Analysis Determination of Suitable Locations for Residence in the city Thesis / individual project / 2012 Spatial analysis (scale 1:10,000 - 1:25,000)

Residence is the city main building use and apart from labor location, all decisions made are related to the residence position. Almost every citizen’s movement has a direction from and to the house location.

As residence plays a central role in citizens’ every life, any user activity or choice is connected with the distance from residence location or best expressed with its timedistance.

The study deals with spatial analysis of land uses in the city and attempts to approach the issue of “suitable locations for residence in the city”, through a multicriteria weighted analysis in urban space. This methodology is based on an analysis of city uses and on the definition of relations among themselves and with the resident-user.

Basic parametres of methodology are the categorization of land uses and the time-distance function. In this study is presented the creation of a combined analysis model, that aims to answer the question of the most suitable areas for residence, depending on the demands of the user. The model was applied in the area of the Municipality of Kalamaria, in Thessaloniki.

Model results in study area

Thesis

Spatial analysis of land use is not an one-dimensional process. The urban fabric is part of the “socio-economic superstructure� which is related to the dominant mode of production and spatial planning or best expressed to the dominant political system.

Citizen develops relations with building uses and functions in the city, interacts with them and is being affected on his everyday life. Relations could be either attractive or repulsive or even indifferent, in a higher or lower degree. As a result, time-distance from land use is a basic factor for choosing the most suitable location for residence in the city.

In the study, the research for the suitable location for residence is determined to a satisfactory degree, as the final image does not lead to an absolute solution but refers to a set of responses across the study area.

Determination of suitable locations for residence in Municipality of Kalamaria

In this way, could be easily made a comparison between different spatial sectors (neighborhoods), in the fulfillment of the criteria. Rating study area, as to the suitability for housing, in the scale of 0 to 100 ranks all results in probable and less probable solutions, in order to become the result of spatial analysis of uses best understood. Using this method, imaging of intermediate solutions exports a different result compared to the classification values.

Area of preference for residence per age

Thesis

In the following series of images is determined the area of preference for residence per age group. Model results are based on objective criteria, in other words the sample results for the ideal residence location, determine three different spatial units in the study area. According to the current general development plan of the municipality, residence is a use allowed for the spatial units mentioned. The neighborhoods chosen above are characterized by completeness of parks, green spaces, cultural entertainment facilities and a satisfactory level of urban transportation service, therefore the selection of these areas is not random but fully confirmed.

The results of the analysis model are proved satisfactory to certain extend. Nevertheless, there are prospects of further improvement of the model, by introducing and adopting new criteria to the analysis, that are not included in the spatial analysis of uses. A number of these factors are enumerated and described in this study.
