Choropleth map

This is a map that is able to explain and show the trend of increasing increments by varying colors. For this particular map of Great Britian, it shows information about the amount of money that was spent in England by overseas residents, with increasing shades of pink corresponding to more and more money spent. This map is a good tool because it gives a very, very good and easy visual of where the boundaries are for money spent and therefore could provide more interest and questioning into geographic reasoning into why they are such drastic boundary differences between places that are relatively close.

Dot distribution map

Dot distribution maps, such as the one above, are useful because they are able to provide more "specific" information about a certain topic, in this case the number of concrete slab bridges. Dot distribution maps are able to show a very large scale area and then pinpoint if, and how many, of a type of group there is. One important advantage to this type of map is that it is much easier for a reader to understand this type of map because instead of always constantly having to look back to a legend and see which color or pattern relates to what kind of density, they will simply be able to see by the number of dots and how clustered they are.

Propaganda maps

www.jamd.com/image/g/3142188

This map is known as a propaganda map because it uses the simple ideas of maps and twists ideas and thoughts of an unknown, or possible known place, to suit a specific groups needs. This map is a great example of a propaganda map because it is trying to portray how much better China would be if it were ruled by Japan, therefore displaying a map of China with peaceful and happy Japanese people and flags and others running scared. It is a main purpose of propaganda maps to use something that is familiar, like a map, and really change the meaning of it by amplifying some aspect and having that re-shape our previous knowledge, either positively or negatively.

Hypsometric map

research.usm.maine.edu/.../bathymetry/

This is a hypsometric map and it is similar to a topographic map because it shows relief, in this map specifically, by contrasting colors. This map exhibits the differences in elevation in seamounts in New England and how they range in differences as one gets closer to the shelf. These types of maps are important because they are able to help better visualize the differences in land, therefore giving people a better understanding of things that we can not easily such, such as underwater surfaces or even land from far away countries.

PLSS map

The above map is a map of Harrison county in Iowa and is a great example of the Public Land Survey System, or PLSS. This mapping technique is a way in which the U.S. sought to map the land of America in a systematic ways in order to divide land owned by the government into public use. This map shows how the main unit of division is a square and that there are major lines, both horizontally and vertically, as well as smaller lines that divide the large parcels up into smaller ones that are finally used for other services.


Cadastral maps

The above map is a cadastral map and it portrays land that is up for sale in Africa. These kinds of maps are really important because they show some land features such as trees, small roads, and waterways as well as property lines. Cadastral maps are great tools because they are able to show boundaries on a map that are not able to be seen on the ground. Unlike in olden times, when land boundaries were very temporal, such as a row of trees or shrubs, that could be possible destroyed in a storm, this map is able to concretely map out what land is up for sale and what it generally looks like.

Thematic map

notts.localknowledge.co.uk/

This is a thematic map that displays information about the level of poverty and deprivation that exists in Nottinghamshire, England. This map is unique because it is a way in which different levels of deprivation across a certain area in England are accounted for and therefore processed in terms of how much help specific places should get. Although this map doesn't necessarily show any specific geographic features, it is very important because it helps to map out social and, in this case, economic features of land.
