1. Spatial Organization of cities Paola Diaz 10-10206 Luis Torres 06-40382

2. ¿What is spatial organization? Spatial organization refers to the arrangement of Physical an human objects on the earth's surface. Is the ability of place properly the different element of a system with the intention of improve its performance.

3. The city shape It is not possible to define an optimum city shape because city development objectives change with time. However, it is possible to identify the type of city shape that would be consistent with a specific objective. Urban shapes are path dependent. The spatial structure of large cities evolves very slowly and can evolve only in a few directions. On a large scale, it is never possible to bring back to nature the land that has been already developed.

4. The urban structure is a relationship between the interior of the urban space and the various parts that compound the city. Green spaces. Road systems. Patterns. Layouts. Equipment with particular features in the conformation of each city

5. Main features The physical morphology or composition material, to define the layout and organization of the elements of the physical structure of the city. The functional organization is the set of urban, economy, social and how to relate these in time and cultural space.

6. The constituent elements of the urban structure Natural environment: topography Soil types: Bearing capacity Watercourses: rivers, streams, lakes. Type of vegetation: Shrubland, forest, grassland Climate and microclimate: temperature, rainfall, humidity Environment characteristics Landscape features.

7. Build environment: Land uses Road systems Systems of green spaces Equipment Infrastructural support

8. Urban spatial structures The monocentric models of cities the centric zone model The sector model

9. The patter of daily trips The average build-up density Density profile and density gradient

10. The urban planner work Urban planners should attempt and structure cities spacial organization, for them to be fully functional. ¿can urban planners change the shapes of the cities? Urban planners disposes of three tools: Land use regulations Infrastructure investment Taxation
