How many parallels does an regular pentagon have?
It has no parallel sides
What is a map projection where the lines of longitude are parallel called?
That's true of the Mercator projection, among others.
What are shown as straight lines on a Mercator projection called?
The parallels of latitude and the meridians of longitude are all straight lines on the Mercator projection. That's why Greenland looks bigger than South America.
Give an example of parallel projection related to real world application?
hfgh
What are parallels on a map?
Parallels are lines that run the same direction and are the always the same distance apart. On a map (and the Earth) the lines of latitude (measurement North and South of the equator) are parallel.
Is a gnomonic projection a rectangle?
no
What is the advantage of a gnomonic projection?
a gnomonic map makes countries look longer, distorted, and hard to understand
Compare and contrast mercator and gnomonic projections?
Mercator projection is a cylindrical projection that preserves shape and angles, making it useful for navigation, but distorts size and distance at high latitudes. Gnomonic projection, on the other hand, displays great circles as straight lines, showing shortest distances but distorting shapes and areas. Overall, Mercator is better for navigation while gnomonic is better for measuring distances.
Where are land masses distorted on a gnomonic projection?
Land masses are distorted towards the edges of a gnomonic projection, with the distortion increasing as you move away from the center point. The distortion is most noticeable at the outer edges of the map, particularly near the poles.
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
Map projection is used for sea travel?
A map projection that is used for sea travel includes the gnomonic projection. This was most often used to find the shortest routes between points on a sphere.
Do all of the parallels and meridians cross each other at right angles on both the globe and the Mercator?
On a globe, parallels and meridians meet at right angles only at the equator and the poles. On a Mercator projection map, all meridians intersect the equator at right angles, while parallels intersect meridians at right angles throughout the map.
Is the equator a parallelor meridian?
It's actually parallel to the parallels, since the parallels are by definition parallel to the equator.
Is the equator parallel to the meridian?
Nothing is parallel to any meridian. The equator is a parallel of latitude, and is parallel to all the other parallels. This is a big part of the reason that, collectively, they are called 'parallels'.
What are the advantages and disadvantages of the Gnomonic Projection map?
Advantages: pinpoint accuracy, air traffic, and the only way to get the north and south pole. Disadvantages: Makes countries look longer, distorted, and hard to understand.
What are the 4 characteristics of parallels?
Parallels are lines that run east-west on the globe. Parallels are always parallel to each other and do not intersect. Parallels are measured in degrees of latitude. The equator is the most famous parallel, located at 0 degrees latitude.
Which projection has the patient positioned facing the film and parallel to it?
posteroanterior projection
