Landform Drawings Questions

• This type of drawing is created to calculate areas, locate property lines, and locate building projects and facilities:
• These are lines drawn on a map to locate, in the plan view, points of equal ground elevation:
• These maps are used to plan construction projects that locate construction features so they fit the topography of the area:
• These maps are used in planning installations of trees, shrubbery, drives, and other garden features:
• These are accurately drawn maps of cities and towns showing property lines and other features that control property ownership:
• These are vertical distances above a common datum, reference plane, or point:
• These are special installations of stone or concrete marking the locations of points accurately determined by precise surveying:
• A contour interval is the horizontal distance between horizontal planes passing through successive contours.
• Engineering maps are typically made for special projects as an aid to locations and construction.
• Nautical maps and charts show prominent landmarks used for air navigators.
• An elevation drawing consists of a series of intersecting straight lines of accurately measured lengths.
• On a single contour line, all points have the same elevation.
• Topography is the science or art of map making.
• Commonly, elevations are referenced to mean sea level.
• A plat typically shows elevations.
• Differential leveling is the process of using a level and a telescope to determine differences in elevation.
• The bearing of a line is its angle from magnetic south.
• Hatchures are short, parallel, or slightly divergent lines drawn in the direction of a slope.
• Before highway construction begins, it is usually necessary to plan the horizontal and vertical location and alignments.
• Monuments marking surveying points are typically not intended to be permanent.
