Digital Mapping of Reyner Banham's Documentary "Reyner Banham Loves Los Angeles"


View Beyner Banham loves Los Angeles in a larger map

    Neogeography is the modern mapping tool which is very user friendly to beginners who try to make some maps for themself. This tool has great potentials in modern world to extend its functions and services to help geographers or anyone who is interested in making maps. There are some great advantages and potentials in one of the Neogeography application, Google Maps. First, the user interface for the application is simple and straight forward. The user friendly interface welcomes anyone who is trying to use it. Various funationalities are also one of Google Maps's advantage. Although the interface is simple, Google Maps got all the tools which u need to make your map complete and interesting to read. The basic points, lines and polygon shapes are there to help u to make your map clear and easy to understand. different symbols for the points make the map iteresting to read and easy to understand. Google map also allow users to edit or add text, pictures or videos to describe the points or the polygons that are on the map. Finally, you can share your own map, which can be made for any purpose, online and show it to public.
    However, there are some disavantages and pitfalls of using Google Maps to create maps. This map making is totally depending on the basic terrain map which is provided by Google. You will not able to edit ur legend, adding new streets or places which are not yet updated by Google. The basic terrain map ignores elevation making and UTM projections. This overly simplified map is not suitable for more formal map makings. Overall, I think the Google Maps got more potentials and upsides than the disavantages that it have. This tool is great for beginners or amatures to start learning how to make maps. The social tools, that Google Maps have, allow people to share their own map, and will promote enthusiasm in map making in our society. Mapping making is no longer only for the professional geographers.

Interesting Maps


Travel time to major cities (in hours and days)
Travel time to major cities (in hours and days) and shipping lane density 
This map is made by European Commission Research Joint Centre, http://bioval.jrc.ec.europa.eu/products/gam/index.htm. The purpose of this map is to study the concentration of trading activities as our world is getting smaller because of the advanced transportation systems. I found this map particularly interesting because this map shows that high concentration of the trading activities are happening at the high concentrated population areas, such as China and India. Also the more developed countries have more concentrated trading activities than those who are less developed. As we can see that trading are not happening at places like central Africa and central South America, because there are desserts and jungles where has less concentrated population and less transportation.  Also We can see that population and trade are mainly concentrated around 30 degrees north to the Equator.


This map is made by Canadian researchers Aaron van Donkelaar and Randall Martin at Dalhousie University, Halifax, Nova Scotia, Canada, created the map by blending total-column aerosol amount measurements from two NASA satellite instruments with information about the vertical distribution of aerosols from a computer model., http://www.nasa.gov/topics/earth/features/health-sapping.html The map shows the concentration of pollutions globally. I found this map interesting because the air pollution is not only limited to developing countries. Sahara desert has severe pollution because the winds will blow up large amount of the mineral particle which will cause air pollutions. As India and China has their pollutions by directly releasing burned coal waste from factories and power plants



This is a map is from 1906 Atlas by Justhus perthes portraiting the world from direct view from top of the Antarctica. http://en.wikipedia.org/wiki/File:Antarctica_map.jpg . I find this map particularly interesting because usually the map we use are horizontally scroll out facing the equator. usually these maps have lands size proportionally distorted. and this map with view of globe on from the top of Antarcica will show the true size of antica comparing with other continent and a true shape of what Antarctica looks like.
