What are the three main types of map projection?
Three types of projection include planar (the globe is projected onto a flat sheet, with only one point of the globe touching the surface), cylindrical (the globe is projected onto a cylinder with the all points along a great circle touching the surface), or conical (the globe is projected onto a cone with two lines of parallel touching the reference surface).
Describe the two sets of line that are used on globes and some maps?
One line is a projection that maintains accurate distances from the center of the projection or along given lines it is called an equidistant projection. Another line is a cylindrical projection which projects information from the spherical Earth to a cylinder.
Why are the north and south poles blurred on Google Earth?
To suggest that map projection of satellite imagery on to a GLOBE greatly distorts the images around the poles is a complete lie. Distortion at the poles when projecting a globe on to a flat map is known to cause distortion as the meridians are spaced much farther apart at the equator than at the poles. To claim the same applies to a globe is crazy. How would a satellite image around a ball cause distortion in one area vs another? Simple, it would not!
What is the definition of map projection?
A map projection simply is a representation of the round, 3D surface of the earth onto a flat, 2D map. There are different map projections such as Mercator and Robinson each of which have advantages and disadvantages.The appropriate projection for a map depends on the scale of the map and the purposes for which it will be used. For example, a Mercator projection has straight rhumb lines and is therefore excellent for navigation, because compass courses are easy to determine, but there is distortion near the poles.
What type of projection has parallel lines of longitude which disappear near the poles?
Mercator is the type of projection which has parallel lines of longitude which disappear near the poles. The project in question also presents parallel lines of latitude even though the overall clarity gets distorted around both the North and South Poles.
How are conic projections made?
Conic map projections are created by projecting the Earth's curved surface onto a cone. The cone is then unwrapped to create a flat map. This projection method is useful for representing mid-latitude regions with less distortion compared to other types of map projections.
What happens when you take a round globe and put it on a flat map?
It will roll around. To make a flat map from a round globe, a projection is used. In making the projection not all measures can be preserved and so distances will be stretched for some areas, and straight lines on the projection will correspond to curved lines on the globe. There are different projections that can be used which try to minimise the effect on different measures.

Where would you be able to see where the lines of longitude meet more clearly on a map or on a globe?
The answer to this depends on what projection of map you are using and how wide the columnal support on the globe is. Typically though, you'll have a better chance of seeing the lines of longitude converging at the poles on a globe. If you want to see the actual point of convergence, a better choice would be a map projection that has special carve-outs on the bottom for the poles or a "pole perspective projection" which is similar to the map of the Earth used on the UN Flag.
What does the lines in globe equator?
All lines of latitude are parallel to the Equator, except the poles ,which are dot/points.
What projection shows all lines of latitude and longitude as straight lines?
The Mercator projection does that.
What is difference between parallel and perspective projection in Computer Graphics?
Parallel projection does not produces realistic views whereas perspective projection produces realistic viewin parallel projection lines of projection are parallel whereas in perspective projection lines are not parallel and the point where these lines meets is called ceter of projection in case of perspective projection
What is the pattern of lines that circle the globe east-west and north-south called?
The pattern of lines that circle the globe east-west are called lines of latitude, while the lines that circle the globe north-south are called lines of longitude. Together, they form a grid system that helps in locating points on the Earth's surface.
On a globe the meridians converge toward the poles What is the pattern of meridians on the Mercator?
On a Mercator projection, meridians appear as straight, parallel lines running from top to bottom of the map, spaced evenly apart. This is because the Mercator projection is a cylindrical map projection that preserves straight lines of constant bearing, resulting in meridians being stretched vertically towards the poles.
How do meridians that appear on cylindrical projection differ from meriidians on a globe?
Meridians on a cylindrical projection appear as straight vertical lines on the map, while meridians on a globe are smooth curves meeting at the poles. The distortion of meridians increases as you move away from the equator on a cylindrical projection, making them seem more elongated.
Is Greenland larger on a Robinson projection than it should be?
Well, Greenland is BIGGEST on a mercator projection but on a Robinson it is smaller because the lines of latitude remain parallel, and lines of longitude are curved as they are on the globe. This results in lesser distortion near the poles. So your answer is most likely, no. DEPENDING on what map you look at.
Lines of the globe?
The lines on a globe refer to latitude and longitude lines that help locate points on Earth's surface. Latitude lines run east-west and measure a point's distance north or south of the equator, while longitude lines run north-south and measure a point's distance east or west of the Prime Meridian. These lines intersect at specific points to create a grid system used for navigation and mapping.
