2011 Drawings


Looking for reasons

With Radek Stach, and Edmond Hayek we started a project on social, architectural and mental boundaries.

Waste Collector in 4 cities

Numbers brought our (done with Agata Sander) project of Waste Collector Skyscraper to its shape. Forming process is shown below:

Storing silos sizes are constrained with the capacity of barges (up to 1500t), and the duration of anaerobic digestion process of organic waste. The same procedure was applied to data gathered from 4 cities. Approximation was necessary, as the nature of the data varied in each of the cases.

The post-competition part of the project was done at the T3 seminar - Spatial Analysis and Formalisation.



God bless sattelitas.

According to orto-photos it was possible to estimate average height of buildings in areas drawn on the map, and see what happens to the skyline.

starting with the downtown, going outwards in four basic directions, estimated heights were assigned. Heights contain values from 5(for small industry) to 40 (for churches), and further they rely on newspaper knowledge about higher points. As the heights were assigned, the extrusion was proceeded according to (height) ^ 1.5 + 15. Because of that, the higher the point gets, the bigger the difference is. For 5 areas exceeding 60m the top point was taken. For gothic churches and towers, height of the nave's roof defined the total height. For legibility chimneys of power plant wer not taken into consideration.


- first thing is the amazing power of the phallic form in the front (axonometry). We were proud of the highest appartment tower in Poland 3 years ago (presently under construction) , but it is highly possible it will become Silesian Palace of Culture for a long time. There is a plan of building the whole row of towers, so the story would get some dynamism. Let the time tiktak.

- second thing is "urban height section" - what would we get out of a section done on a height model in 10 directions (for example with one end in the center)? Would it say something about density, compression, or should we just control it not to raise backwards? Is there any scenario of height in the city? A gate leading to woods.

- does the height matter?



Development of last work (i.e. typing in some more data), brought a wider view on the city structure. The tram transport nodes create a closed ring around centrally located Old Town and Downtown. Polygon traced after these points covers more or less my emotional map of what is "in", and what is "out".
According to famous schools of urban reading, dense transport net is only one of the features defining "where in is on".

We could count the factor of node's capacity divided by the width of the tramstops, or by the surface of pedestrian pavements between stops of each node. It would be directly connected to potential frustration raised during each change. It is possible that presenting this information would cause riots. We'd better skip that part.

- value for each tram stop is counted in linear proportion to trams stopping. Relatively, the images show the proportion between usage of main nodes. Quantitatively, the capacity was calculated as the number of trams stopping multiplied by 240 (intuitively estimated average capacity of tram), and divided by 5, according to estimation that in the city center personal average travel would be 2,5km long (average 500m between stops). No correction for the filling of wagons.

Accessibility of transport and easiness of mobility, let us agree again, are among the most important activators of urban life. As simple as that. Continuing first post concerning this topic (with photos of four nodes), if you look at the satelite images of these " local hubs", especially in the northern part of the city, you would understand why citizens choose to spend 2 hours a day in their cars.

Let the society act! Let's make the pedestrian routes broader!

P.S. As we zoom it, the view becomes warmer.

Data Management

In managing available data two masses may be involved: hands or brain.

Download file "Methods of managing data.jpg"

After some experience with retyping data from website, checking compatibility with map, and writing up a new data sheet, I wish everybody to learn methods how to connect any datasheet to drawing. It is useful, for one can work on mastering THE QUESTION, not fingerjoints. As WiseGuys say, the most valuable professional is the one who asks the most unexpected question, not the one who knows.



Referring to K.Wejchert (who referred so much to K.Lynch), city nodes are these wonderful areas giving us a wide bunch of spatial referrences, improving navigation, enabling short-time flaneur (e.g. while waiting for tram). These values are important part of urban life of western-world societies.

Let's look at the relative capacity of most important nodes of Wrocław's center. It is presented for part of tram movement during morning peak (7-9 a.m.) on workdays. The methodology is described in "Borders of the city center" post.

We could imagine, that these nodes demand special urban treatment - significant points, arrangement facilitating transfer between stops, safety of pedestrians, bike stands, parkings... We can see how does it look like presently:

When the autoroute belt (AOW) is open (june 2011), considerable part of car traffic will move out of the city. Wrocław's development could spread"the good image" of the city out from the city center, and redesign these squares. Currently, they define the border of "in", and "out".


Emotional impact of presented data

Let us see a simple example:Download file "ACCESS to tram lines in Wroclaw.jpg"

Both images represent the same information, the only difference is hidden in basic rules of building an impression: color, size, point of view, and relation of elements.

The idea of propaganda is as old as mating dance, but there are always some people who didn't learn its basic rules. One must choose precisely what one proposes or shows.

So I say.



Today's investigation brought the information that already 28% of Wroclaw's built areas (no specific data about the type and inhabitants) is well connected to public transport system. In 3 minutes of walk one can access at least one tram and one bus stop.

Attached map shows, that apart from the center, good and average access spreads out to the southern districts. It could explain, why in recent years these parts concentrated almost 50% of residential investments in the city. Appartment costs are of the highest in Wrocław, and they were the most desired localisation for living.

Other explanations would say something about parks, social/cultural infrastucture, but I these informations exceed the scope of this work.

Funnily, part of the town hall in the middle of Old Market Square is in "very bad" connection to public transport is .

It is also interesting ,that south-west and west part of the city, is omitted by public transport. Even though it is inhabited by 30% of Wroclaw's citizens. As legend says, these areas have been for last 150 years covered with industry and inhabited by its employees, so the municipality doesn't care.

2nd step

The amount of data we are able to gather and manage is amazing. I met dr Brzuchowska in Wroclaw, who shared some observations about the conflict possibility vs. reality with me. From this time I strongly believe- one standard of exchange for all the "managing people"- in GIS as well as in discussion, government, education.

On the material I got I started with distances to the tram stops. Next ideas are going on.

Still waiting for any sign from garbage systems.

1st step

This blog will show the path of creating a basic GIS analysis - execute simple spatial quantitative analysis on a scale of a chosen city. It will allow to understand elementary methods and potential outcomes of using Geographic Information System. Available tools allow us to find a lot of interesting information that is useful in managing the city.

Two tasks will occupy this story:
1. Public communication according to distribution of workplaces in the city,
2. Spatial description of municipal solid waste transport
both analysis will be executed on the case of Wroclaw.

First step is to collect any useful spatial data (maps, statistics, files etc.)

I wrote a request to dr Brzuchowska of Municipal Spatial Information Office, Municipal Solid waste companies (Transformers, WPO ALBA), Municipal Communication Enterprise (MPK), and some guys of BRAMA (WUoT- they deal with topics of use of public data), Centrum Cyfrowe, and City-nav- guys from jakdojade.pl.

Hopefully they will answer.

Let us be patient.
