Contour plowing and terracing?
Contour plowing is the farming practice of plowing across a slope following its elevation contour lines. On sloped land, contour plowing is done such that rows are side by side but each row follows a path such that every point on it is at the same elevation. So, for example, to plow a round hillock you would plow concentric circles around the hill top to bottom. The resultant furrow lines look just like the contour lines on a contour map. With this plowing method the rows hold water instead of draining it downward and becoming eroded.
How does a relief of an area determine the contour interval used on a map?
Roxanne Lipsey: Contour lines are drawn at specific intervals, such as every 10 feet, 20 feet or 30 feet. Each line represents a multiple of the scale chosen. Using the 10-foot scale as an example, each contour interval would represent a 10 feet change in elevation.
What is difference of metric photogrammetry and interpretative photogrammetry?
PHOTOGRAMMETRY METRIC PHOTOGRAMMETRY INTERPRETATION Measuring from ground position, elevation distances, areas and volumes. Existing in a qualitative manner like timber stands, water pollution, soils, geological formations, crops and military interpretation. Determine relative locations of points, scales, angle and sizes or shapes of objects. Recognizing and identifying objects on aerial imagery and judging their significance. Preparation of planimetric and topographic maps from photographs. To analysis photographic images Photographs taken from airborne vehicle(aerial) and terrestrial photos(earth-base) Gathered data from a wide variety of sensing instruments such as remote sensing
Do Stars have points?
No. Real stars do not points.
What is a locus of points equidistant from a point?
A locus of points is just the set of points satisfying a given condition. The locus of points equidistant from a point is a circle, since a circle is just a set of points which are all the same distance away from the center
What is a contour on a topographic map?
A contour is a line that joins points of equal elevation.
A what connects points of equal elevation on a topographic map?
contour lines
What connects points of equal elevation on topographic maps?
contour lines
What do contour lines on a topographic map show changes in?
Contour lines on a topographic map show changes in elevation. They connect points of the same elevation, allowing you to visualize the shape of the land and understand its topography.
What is a Contour line on a topographic map?
A contour line on a topographic map represents a specific elevation above sea level. It connects points of equal elevation and helps to show the shape of the land, such as hills, valleys, and slopes. The spacing between contour lines indicates the steepness of the terrain.
How can one determine elevation using a topographic map?
To determine elevation using a topographic map, look for contour lines that connect points of equal elevation. Find the contour line closest to your location and determine the elevation value listed on that line. Elevation can be calculated by adding or subtracting the contour interval value from the listed elevation.
Can a contour line on a topographic map connect to a point with an elevation of 100 feet to a point of 110 feet?
No. Contour lines connect points of the same elevation
Line drawn on a topographic map to join points of equal elevation?
lines of equal elevation are called contour lines.
What would the highest and lowest points in an area like on a topographic map?
On a topographic map a contour line connects points of equal elevation.....hope that helped
How can one determine the elevation on a topographic map?
To determine elevation on a topographic map, look for contour lines that connect points of equal elevation. The elevation can be found by reading the numbers on these lines. The closer the lines are together, the steeper the terrain.
What is the difference between and index contour and a regular contour line?
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
What do all the points connected by a contour line have in common?
elevation & the unit is in feet
