Mapping Lab

Maps do more than give directions. They can also give you specific locations, give reference from a specific location to another location and give description of that location as well.
An interesting website that can give more information about story maps is provided below.
Story Maps!

Here are some different types of maps.

Chloropleth Map

- this map is a thematic map where certain areas are patterned in proportion to the statistical variable that is being measured that is illustrated on the map, such as crime rates or per-capita income. 
- They may compare a whole country, continent, or only a state.
 Here are a few examples:


This map, however, does not have a scale nor a North arrow or compass to show direction.

Isopleth Maps

This type of map is ideal for showing gradual change over space and avoids the abrupt changes 

which boundary lines produce on choropleth maps. Temperature, for example, is a phenomenon that should 

be mapped using isoplething, since temperature exists at every point (is continuous), yet does not change 

abruptly at any point (like population density may do as you cross into another census zone).

Here is an example.


This map contains a scale, but no North arrow or compass. All maps should have this.

Dot Density Map

A dot density, or dot distribution map is a map that uses a dot symbol to express a feature or phenomenon. 

 There are two different types of Dot Density Maps:

1. One-to-One Map

Each dot represents one single recording of a phenomenon.

2. One-to-Many Map

Each dot on the map represents more than one of the phenomena being mapped.

Here are some examples.



Both of these maps have scales and the North arrow. These are great examples of maps.

On Google Earth, software that is the technological form of a map, information at the bottom can give the 
elevation, altitude, and Cartesian coordinates of the location currently being viewed. Here is a screenshot of the path put on the elevated areas of Palm Springs, California.
