navigation?

mercator projection
linear projection

Mercator Projection

Explanation:

Since the beginning of time people have struggled with how to represent the surface of the earth on a plane.  

The major problem is that the earth is round while the plane is not, making difficult to express exact distance and proportion.

Overtime different type of projections have been studied in order to pursue different objectives: the Mercator projection  has straight parallel lines and is often used for ship  navigation.

It was invented by Gerardus Mercator in 1569, and it's one of the most common representation of the earth.

It is used for navigation purpose because it helps navigator design straight lines, but it has some major issues in terms of disproportion between places.

it depends on the situation, but in a definitional sense, irrendentism is more valid.

explanation:

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.
