  2. Grade (slope) - Wikipedia

    en.wikipedia.org/wiki/Grade_(slope)

    Grade (slope) The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper ...

  3. Slope - Wikipedia

    en.wikipedia.org/wiki/Slope

    Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

  4. Strike and dip - Wikipedia

    en.wikipedia.org/wiki/Strike_and_dip

    The angle of the intersection with the green plane is the red plane's apparent dip in the northward direction . When measuring or describing the attitude of an inclined feature, two quantities are needed. The angle the slope descends, or dip, and the direction of descent, which can be represented by strike or dip direction. [4]

  5. Inclinometer - Wikipedia

    en.wikipedia.org/wiki/Inclinometer

    An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity 's direction. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator.

  6. Gradian - Wikipedia

    en.wikipedia.org/wiki/Gradian

    54′. In trigonometry, the gradian – also known as the gon (from Ancient Greek γωνία (gōnía) 'angle'), grad, or grade[1] – is a unit of measurement of an angle, defined as one-hundredth of the right angle; in other words, 100 gradians is equal to 90 degrees. [2][3][4] It is equivalent to ⁠ 1 400 ⁠ of a turn, [5] ⁠ 9 10 ⁠ of ...

  7. Tape correction (surveying) - Wikipedia

    en.wikipedia.org/wiki/Tape_correction_(surveying)

    L= Inclined length measured A= Inclined angle When distances are measured along the slope, the equivalent horizontal distance may be determined by applying a slope correction. The vertical slope angle of the length measured must be measured. (Refer to the figure on the other side) Thus, For gentle slopes, < %

  8. Tobler's hiking function - Wikipedia

    en.wikipedia.org/wiki/Tobler's_hiking_function

    Tobler's hiking function. Tobler's hiking function – walking speed vs. slope angle chart. Tobler's hiking function is an exponential function determining the hiking speed, taking into account the slope angle. [1][2][3] It was formulated by Waldo Tobler. This function was estimated from empirical data of Eduard Imhof.

  9. Slope stability - Wikipedia

    en.wikipedia.org/wiki/Slope_stability

    The slope stability probability classification (SSPC) [19] [20] system is a rock mass classification system for slope engineering and slope stability assessment. The system is a three-step classification: ‘exposure’ , ‘reference’ , and ‘slope’ rock mass classification with conversion factors between the three steps depending on ...
