Subject: Mapping Cities 01
In this experiment, I tried to understand some of the skills and techniques used in mapping to understand the cities context. through reading the attributes of city statistics and analysing its data, we were able to visualise valuable information, kind of information we can’t understand through reading long tables of textual and numeric data.
In the picture above, you can see the benefits of mapping techniques, in visualising the distribution of population density across the country in Britain, The difference in colours and heights show clearly how population gathers massively in London and its surrounding, and how each city do.
Another Visualisation from Google show simply how businesses scattered around the city of Khartoum, the capital of Sudan, businesses mainly based on the centre of the city, and then distributed randomly across south-west Bahri and west of Omdurman.
In the other hands, a partial map of central London, showing the classification of different businesses around the city.
from the same map, we succeed to extract different data, this time, we visualise the differences of street types, according to their size and use, whether it local or private, wide or narrow ..etc.
It’s also possible to analyse maps contents through working on raster images of informed remote sensed maps, in this picture, we were able to visualise the heights and surface terrains of the area of Khartoum using the method above, lowlands are shown clearly around the Nile valley.
In the exercise above, visualisation shows the relationship between the contamination and the cancer cases caused by the pollution accrued in the area under the study.
Finally, a 3D map shows the variety of building sizes using the z-axis. this kind of maps which reveal the footprint of the specific building and its effects on the land uses.
