Shin Huoy's GIS Portfolio

During the course, I learnt about the different map projections and the types of distortions they create. Map projections always create some sort of distortion as it is impossible to depict a 3 dimensional globe on a 2 dimensional surface without losing some data.

 

The different types of projections that I was introduced to include: Robinson Projection, Mercator Projection, Stereographic Projection, Alber's equal area conic projection etc. Each projection has different types of distortion and hence are suitable for different purposes and geographical areas.

 

I was tasked to create maps to compare the land areas of Germany and Ontario, Canada. In order to compare the land area, a projection which does not distort areas must be chosen, hence I chose the Albers Equal Area Conic projection. To centralize the maps on different regions in the world, I changed the central meridian of each projection to the respective longitudes of Germany and Ontario. I had to ensure that both maps were based on the same scale.
