The contour interval depends upon the general topography of the terrain. For Example Consider following two scales.
The contour interval selected should be.
Contour interval depends upon. The contour interval depends upon the following factors. What is Contour line Contour map contour interval. The contour interval depends upon i The nature of the ground.
And for a large-scale map it may be 025 m. 025 m 05 m 075 m etcFor a steep slope in a hilly area is considerable eg. Contour line The intersection line joining level surface and ground surface is known as contour line or the line joining the points of equal reduced level.
FACTORS ON WHICH CONTOUR -INTERVAL DEPENDS The contour interval depends upon the following factors- i The Nature of the Ground – In flat and uniformly sloping country the contouruniformly sloping country the contour interval is small but in broken and mountainous region the contour interval should be large otherwise the contours will come too close to each other. Characteristics of ground The correct answer is. The contour interval depends upon the.
A contour means an imaginary line passing through points of equal elevation on the surface of earth. 18 Oct 2017 10 Sep 2018. Contours are generally referred to any undulation in the flat surface.
If the numbers associated with specific contour lines are increasing the elevation of the terrain is also increasing. The correct Answer Is d all of these. Index contours are bold or thicker lines that appear at every fifth contour line.
Contour interval is the vertical elevation difference between any two consecutive contours. Contour interval depends upon the following factor. For example if the survey is intended for detailed design work or for accurate earthwork calculations a small contour interval is to be used.
Anature of the ground Bscale of map Cpurpose and extent of survey Dall of these. Each contours is defined by the joining of all the contour intervals along the same plane. The contour interval depends upon the – a nature of ground b scale of map c purpose of and extent of survey d all of these.
1 cm 10 m and 1 cm 100 m. Contour interval is inverse proportion to the scale of the map. Purpose and extent of survey.
1 Nature of ground In flat or uniformly sloping countries contour intervals are kept small while in steep or broken countries contour interval. A contour interval is the vertical distance or difference in elevation between contour lines. In the cross-section method of indirect contouring the spacing of cross-sections depends uponi contour intervalii scale of planiii characteristics of groundThe correct answer is.
This interval depends upon the nature of the ground the scale of the map and the objective of the surveyContour intervals for the flat country are normally small eg. Find an answer to your question Define the term contour interval. It is inversely proportional to scale of map.
Contour interval depends on following factors. If the ground is more broken greater interval should be adopted otherwise the contours will become too close to each other. Nature of the ground.
Leave a Comment Civil Engineering surveying By Admin. For very flat ground a small interval is necessary. Contour Intervals Depend Upon.
Similarly for a small-scale map the interval may be 1 m 2 m 3 m etc. If the scale is small then the contour interval should be large and vice-versa. Scale of plan 3.
In the cross-section method of indirect contouring the spacing of cross-sections depends upon_____. For a given contour interval the contour interval depends upon the steepness of the ground. 5 m 10 m 15 m etc.
Contour interval depends upon. Ii The purpose and extent of. In the cross-section method of indirect contouring the spacing of cross-sections depends upon.
Describe the factors on which contour interval depends 2. The Scale of The Map. In flat ground contours at small intervals are surveyed to depict the general slope of the ground whereas high hills can only be depicted with contours at larger contour interval.
Factor affecting contour interval. Describe the factors on which contour interval depends rohankumar59 rohankumar59 05062020 Social Sciences Secondary School answered Define the term contour interval. The contour interval depends upon whether the country in flat or highly undulated.
Scale of the Map. The contour interval depends upon the. If the scale is small the contour interval is kept large and vice versa so as to avoid overcrowding of contours.
The contour interval largely depends upon the purpose and the extent of the survey.
