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 projections are made by projecting points and lines from a globe onto a cone
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
Are Lines of longitude and latitude are used for locating certain points on the globe?
Yes. The intersection of a line of longitude and a line of latitude is a point on the globe, and that point is identified by the longitude and latitude of those lines.
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.
What are projection lines?
Projection lines are used to establish relationships of part featurues between rotated veiws of the same drawing.
Why are lines of latitude and lines of longitude perpendicular?
a) planar projection B) cylindrical projection
How many lines of latitude are there when drawn at interval of 1 degree each?
If drawn on a globe at intervals of one degree, there would be 178 lines and two points.
