Question 5

• Angles between adjacent
  lines in a closed polygon.
• They may be measured
  clockwise or counterclockwise.
• Re-entrant angles are
  interior angles greater than
  180 degrees.
• The sum of the interior angle
  of any polygon is equal to
  (n - 2)(180 degrees), where
  n is the number of sides.

Answer 5

Interior Angles

Question 6

• Angles located outside a
  closed polygon.

Answer 6

Exterior Angles

Question 7

• The angles between a line and the prolongation of the preceding
  line.
• May be turned to the right (clockwise) or turned to the left
  (counterclockwise) and appended with letters R or L.
• Right deflections have the opposite signs of left deflections
• Positive signs normally defines angle with deflection to the right.
• May have values 0 to 180 degrees but often not used to angles
  greater than 90 degrees.
• In a close polygon, the algebraic sum of the deflection angle should
  always equal 360 degrees.

Answer 7

Deflection Angles

Question 8

• These are angles measured clockwise from the preceding line to the
  succeeding line.
• This is also called Azimuths.

Answer 8

Angles to the Right

Question 9

• Acute horizontal angles between the reference meridian and the line.
• Contains angles that are between 0 to 90 degrees.
• It always starts on either N or S and will turn E or W.
• Bearings can be measured in reference to True or Magnetic meridian.

Answer 9

Bearings

Question 10

• The angle between the meridian and the line measured clockwise.
• Contains angles that are between 0 to 360 degrees.
• Reference meridian can be the N or S.
• Azimuths can be true, magnetic, grid or assumed.

Answer 10

Azimuth

Question 11

An imaginary line between the North Pole and the South Pole, drawn on maps to help to show the position of the place.

Answer 11

Meridian

Question 12

• Also called astronomic or geographic meridian.
• This line passes through the
  geographic north and south of
  the earth and the observer’s
  position.
• The generally adapted
  reference line in surveying.
• The direction of true meridian is
  invariable and unchanged
  regardless of time.
• True meridian is used for
  markings of land boundaries.

Answer 12

True Meridian

Question 13

• A line of reference parallel to the
  magnetic lines of force.
• Magnetic meridian is not parallel
  to the True meridian.
• This utilizes the magnetic needle
  of a compass to locate the
  magnetic north.
• Used in rough surveys since the
  magnetic meridian changes
  constantly along with the
  location of the magnetic poles.

Answer 13

Meridian Magnetic

Question 14

• A fixed line of reference parallel to the central meridian of a system plane rectangular coordinates.

Answer 14

Grid Meridian

Question 15

• This is an arbitrary chosen reference point
  taken for convenience.
• This utilizes a well defined and permanent
  reference point.
• Applicable plane surveys of limited extent

Answer 15

Assumed Meridian

Question 16

*are control points of permanent location where other surveys are referenced from.

Answer 16

Bureau of Lands Location
Monument (BLLM)

Question 17

is an intrinsic constraint on a site’s development potential.

Answer 17

Parcel size

Question 18

off-site factors are more likely to influence the site’s design.

Answer 18

Smaller sites

Question 18

• allow greater flexibility in arranging program elements on the site.
• allows for the integration of green space, including natural areas and new plantings to separate incompatible uses, screen undesirable views off site, and filter and retain storm water.

Answer 18

Larger sites

Question 19

can reduce development potential and design flexibility.

Answer 19

Shape

Question 20

Understanding the site’s topography is essential in making
good site planning and design decisions (Largo, 2013).

Answer 20

Topographic Map

Question 21

*data are portrayed on topographic
maps as contour lines and spot elevations.

*For site planning purpose, an effective way to
visualize topographic relief is to create a
choropleth map of elevation.

Answer 21

Elevation

Question 22

A contour line is the graphic representation of a contour on a plan or
map indicating locations with equal elevation.

*A gradual rather than an abrupt
change is assumed to occur
between adjacent contours.

*This smoothing effect that gives the
cone and the pyramid their true form.

*The ability to dissect landforms into
their various components shapes and
to understand the relationship of the
shapes to each other will make the
task of analyzing, interpreting, and
visualizing the landscape easier.

Answer 22

Contours and Form

Question 22

*Spatial variation in a site’s elevation creates slopes that have both a gradient and an orientation.
*In site planning, moderate (8 to 15%) to steep slope (15 to 25%) would require soil protection or stabilization while flat terrain (<1%) would be challenging in terms of drainage.

Answer 22

Slope

Question 23

- influences microclimate by affecting the amount of solar radiation striking the site.

Answer 23

Aspect

Question 24

*Topography and landform can be analyzed by constructing a section. *A section is a drawing made on a plane, which vertically cuts through the earth and/or an object like a building. *The ground line delineates the interface between earth and space and illustrates the relief of the topography.

Answer 24

Constructing a Section

Question 25

- is raised, elongated landform. At the narrow end of the form the contours point in the downhill direction. *Typically, the contours along the sides of the ridge will be relatively parallel, and there will be a high point or several high points along the ridge.

Answer 25

Ridge

Question 26

*is an elongated depression that forms the space between two ridges. *Valleys and ridges are interconnected since the ridge side slopes create the valley walls. A valley is represented by contours that point uphill. *Since the contour pattern is similar for both ridge and the valley so it is important to note the direction of slope.

Answer 26

Valley

Question 27

*is a landform, such as a knoll, hill, or mountain, which contains the highest point relative to the surrounding terrain. *The contours form concentric, closed figures with the highest contour at the center. *Since the land slopes away in all directions, summits tend to drain well.

Answer 27

Summit

Question 28

* is a landform that contains the lowest point relative to the surrounding terrain. *Graphically, the lowest contour is often distinguished by the use of hachures. Since depressions collect water, they typically form lakes, ponds, and wetlands.

Answer 28

Depression

Question 29

-are characterized by contour lines that are spaced at increasing distances in the downhill direction. *This means that the slope is steeper at the higher elevations and becomes progressively more flat at the lower elevations.

Answer 29

Concave

Question 30

is the reverse of a concave. *Slope having contour lines are spaced at decreasing distances in the downhill direction. The slope is flatter at the higher elevations and becomes progressively sleeper at the lower elevations.

Answer 30

Convex

Question 31

* Along a uniform slope, contour lines are spaces at equal distances. * The change in elevation occurs at a constant rate

Answer 31

Uniform Slope
