In response to the reading, Mapping is a fantastic instrument to uncover, reveal, either portray the uncovering world those we have never imagined before. Just like Corner described in The Agency of Mapping: Critique and intervention, the function of mapping is less to mirror reality than to engender the re-shaping of the world in which people live. This fact can be illustrated by the space photograph of the whole earth taken by Apollo Astronauts, which opened up our imagination of the way we have visualized the earth.
Cartography or the science of mapping has been developed for many centuries, by inventions of humanity are allowed cartographers(both conventionally trained or not) to create a miniature figure of the reality. From the creation of mercury barometer was used to measure and plot altitudes, aerial photography was expanded the view of the earth surface beyond the ability of human eyes, remote sensing has extremely changed the way how we are surveying and gathering data, science has played important roles on mapping knowledge. On the other hand, human eyes has remained crucial element of mapping and the use of the map like the critique that Cosgrove made in his article. Additionally, visualization of the information on maps will be succeeded by the connection between scientific map making and creative art practices in order to deliver the message to majority of people who are not an expert.
Mapping is not only tool to depict collected data but also functions as the parameter in sociopolitical context. Many maps have conveyed important decision as such in urban planning, in many cases, they shape how physical environment will be formed or will be destroyed.
In the case of the studies of Tunnel No.3, I personally agreed that the most challenging aspect is that the produced maps are not displayed to public as it should because of its social and politic reasons. Even though, we can’t deny the fact that the clarity of the project is essential for our society, compilation of accurate maps, social opinions and critical map making processes will be the chance to bring up new perspective of the project.
