A. A. Clinographic curve illustrates the average gradient between successive contours and shows up prominently any abrupt change in the general relief depicted on a map.
B. B. The relation between horizontal and vertical scales is known as horizontal exaggeration.
C. C. A profile drawn along the stretch of road, or a river, is called longitudinal profile.
D. D. A cross profile gives a panoramic view with a distant sky-line, a middle ground and a fore-ground.
Choose the correct answer from the options given below:
Terrain Mapping Techniques Analysis
This section provides an analysis of statements related to terrain mapping techniques.
Terrain Mapping: Statement A Analysis
A clinographic curve is used in map analysis. It effectively displays the average gradient between adjacent contour lines. This curve prominently highlights abrupt changes in the map's depicted relief, offering insight into steepness variations.
Conclusion: Statement A is correct.
Terrain Mapping: Statement B Analysis
Horizontal exaggeration relates the horizontal scale to the vertical scale, typically when the vertical scale is amplified relative to the horizontal scale to emphasize topographic features in profiles or 3D views. The statement defines it broadly as the 'relation between horizontal and vertical scales', which lacks the precision regarding the ratio and purpose (amplification of vertical dimension).
Conclusion: Statement B is considered incorrect.
Terrain Mapping: Statement C Analysis
A longitudinal profile is a type of topographic profile. It specifically represents the elevation changes along a linear feature, such as the course of a river or the planned route of a road.
Conclusion: Statement C is correct.
Terrain Mapping: Statement D Analysis
A cross profile illustrates the shape of the land across a specific line, usually perpendicular to the main direction of a feature like a river. A panoramic view with a skyline, middle ground, and foreground is characteristic of a perspective sketch or artistic representation, not a standard topographic cross profile.
Conclusion: Statement D is incorrect.
Terrain Mapping Conclusion
Based on the analysis, statements A and C accurately describe terrain mapping techniques. Statement B is imprecise, and statement D incorrectly defines a cross profile.
Therefore, the correct statements are A and C.
