FOREST MEASUREMENTS EXAM 1
QUESTIONS & ANSWERS(RATED A+)
Compartment/unit - ANSWERa grouping of stands for the purpose of management,
usually based on location
Stand - ANSWERa unit of forest land delineated by age class, species structure,
ecosystem type or other cohesive unit
Sampling point - ANSWERa point in a stand where measurements will be taken, can
be a randomly chosen or systematically chosen point depending on sampling
method
Plot - ANSWERanother name for a sampling point, can be a fixed permanent plot
(research or systematic cruise) or random plot (coordinates chosen at random)
Routing Off Protocol - ANSWERto minimize personal bias and maintain consistency
of measurements and calculations it is good to use a systematic approach to
rounding. For example: if you have 27.65 and 104.15 you can look at the number
preceding the 5 - If it is even, then ignore the 5 and the digit remains the same 27.65
become 27.6. If the preceding number is odd, then round up 104.15 becomes 104.2
Precision - ANSWERcoming as close as possible to measuring the actual real world
metrics of our stand of interest with each measurement. The clustering of sample
values around their own average. Ex: all the dominate trees in the plantation should
be around the same total height.
Accuracy - ANSWERexactness, correctness, freedom from error
Coordinate geometry - ANSWERa grid system with a central point used to locate
points of interest such as measurement trees within a plot
Geographic geometry - ANSWERa coordinate system that enables every location on
the Earth to be specified by a set of numbers and letters so that one of the
numbers/letters represents vertical position and the other set represent horizontal
position. We will focus on coordinates of latitude, longitude, and elevation
UTM - ANSWERUniversal Transverse Mercator is a conformal projection that uses a
2-dimensional cartesian coordinate system to give locations on earth. Know that
UTM zone number runs north/south, has a center point from which locations within
the zone are mapped in distances E or W
SPS/SPCS - ANSWERUS State Plane Coordinate System is not a projection. it is a
coordinate system that divides the US, Puerto Rico, and the Virgin Islands into more
than 120 numbered sections referred to as zones.
