What is the distance between two contour lines called?
The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called index contour lines.
How accurate is Google Earth elevation?
The GDEM data are the most widely covered elevation data source (from 83°N to 83°S, covering about 99% the globe) with a grid resolution of 30 meters. A vertical accuracy study found the root mean square error (RMSE) of GDEM data is 8.68 meters when compared against 18,000 geodetic control points in the USA [14].
What can an elevation map show you?
An elevation map shows the height of physical parts of the Earth, relative to sea level.
Do geologic maps show elevation?
Topographic maps reveal the shape of a landscape. Elevations indicate height above sea level. Contour lines are lines of equal elevation. Geologic maps show rock units and geologic features, like faults and folds.
What color represents higher elevation?
Dark green usually represents low-lying land, with lighter shades of green used for higher elevations. In the next higher elevations, physical maps often use a palette of light brown to dark brown. Such maps commonly use reds, white, or purples to represent the highest elevations shown on the map.
Which Colour is used to show mountains and hills on maps?
The color brown is used to denote most contour lines on a map, which are relief features and elevations.
What Colour is used for mountain in map?
For example, generally blue is used for showing water bodies, brown for mountain, yellow for plateau and green is used for plains.
What is the common Colour of hills?
The highest elevations are typically gray and white. This color scheme mimics the progression from forest to grassland to bare rock and then ice and snow. Many maps are colored according to the tastes of the cartographer but a gradation from green to yellow, orange and red is common.
Why do the Google colors mean?
Someone at Google stated that the reason they do this is to show that they are aware of the primary colors and decided to show the coloring that the company uses in their branding while daring to be different with the ostracized and independent “L” that stands by itself.
