Analysis of Warsaw with raster based GIS

Background

Especially in developing countries, where most of the world biggest cities are located, there is growing concern on the difficulties to monitor and guide development in terms of efficiency and sustainability.  At the same time, the improvement of information technologies and increasing availability of data in useful formats is allowing us to develop customised tools to support urban management more precisely.  The approach presented here has been developed as a strategic tool to identify the areas with best conditions for the most common types of infrastructure development, assess its possible impact and thus track constraints and opportunities for investment in a plausible and understandable fashion. The method used is a raster based GIS that links spatial data, state of the art approaches, existing development plans and local planners judgement, all of which lead to considerations for further discussion with stakeholders, users, etc. The case study presented here tries to demonstrate that spatial information technologies, relevant data and a practical method as proposed here may lead to a low-cost assessment solution, especially designed to be applied wherever time and funds are limited.

Warsaw Model Results

Opportunities for mixed development Not surprisingly, the figure showing areas with opportunities for mixed development does underline the existence of prime areas in the city centre (Srodomescie), mainly along the most important streets around the [1] Palace of Culture at Defilad Square, [2] Central Station, etc. but it also shows important areas on the eastern side of the River Wisla in the borough [3] Praga Poludnie, which contains a large number of industrial brown fields. As well there is a remarkable concentration of cells with high values in the northern borough of [4] Bialoleka, which is currently mainly underused farmland and a fairly large concentration of cells with high value in the area of [5] Ursus, which contains at the moment mostly residential areas with medium density. Public development and provision of services The model confirms that the city is still very centralised, because mostly the central boroughs appear to feature services of public infrastructure. Exceptions to this seem to be the boroughs of [1] Ursynow, which is served by the Warsaw metro and the southern part of [2] Bielany, which will be connected to the metro network in the near future. In the case of Bielany, there is as well a strong contrast between the mainly residential southern part and the industrial north, which is clearly pointed out by the model results. The boroughs of [3] Wawer and [4] Wilanow however are clearly underserviced. Main reasons may be their scarce road communication to the rest of the city and low population density. Environmental Quality This model shows a twofold in the existing environmental conditions of Warsaw. There are on the one hand extensive areas at low risk. These are mainly areas with less built density and areas that have a high environmental value. For example in the districts of [1] Wawer and [2] Wesola, which contain important forests and fresh water sources. The river Wisla would also count to this category, excepting in the vicinity of the [3] city centre and of a [4] landfill area south of Wilanow. On the other hand, there are throughout the city many "green" spots with environmental importance but which are disconnected from each other. This suggests the opportunity to create wildlife corridors for fauna, as well as networks of amenity space for pedestrians, cyclists, etc, which should be analysed closer. Average values and currently promoted areas The model showing average values is representative for all 3 estimations. The image shows as well the location of six potential locations for investment identified by the Warsaw city council. These are confirmed by the model. The model as well confirms that some areas mainly in the south of Warsaw lack of appropriate framework conditions for investment. These areas are mainly in [1] Wilanow, [2] Ursynow, [3] Wlochy, [4] Ursus and [5] Targówek. The Warsaw municipality should considerate investing on the improvement of public space and services in these areas in order to attract and support private undertakings here.
GIS & RESEARCH
Data   A GIS database was created with spatial information acquired from an extensive survey undertaken before March 2006 by the Warsaw Municipality (2006, Prezydent Miasta Stolecznego Warsawy ) which I digitised between January and May 2007. Information contained in maps in a scale 1:20 000 display current infrastructure and resources regarding topics like "functional structure", "cultural heritage", "natural heritage", "land property", "road categories configuration", "public transportation", etc. Other web based sources like Google Earth, Collaboration Websites and the municipal government website provided spatial and tabular data about density, built environment, political boundaries, landmarks, etc.
