RNR 2102 TEST 2 || with 100% Correct Answers.
A= Pier^2
Square root of A/Pie= radius
.2/pie squared= radius
=.25 correct answers Calculate radius of a .2-acre circular plot.
2 DBH class correct answers In what case is the 100% tree tally appropriate?
50 plots x .1 ac= 5ac
5ac/100ac= 5% cruise correct answers Cruise intensity is defined as cruise % . What is cruise %
when 50 plots of size .1 acres each are sampled from a 100 acre tract?
20 ch x 30ch= 600 ch^2 = 60 ac
5% of 60 ac = 60 x 5/100 = 3 ac
3 ac/.2 ac = 15 plots correct answers We want to preform a 5% cruise on a 20 ch. x 30 ch.
rectangular tract. How many .2 acre plots will we need?

Selective Availability correct answers SA
False correct answers T/F: The GPS was not created by the department of defense
True correct answers T/F: A GPS has 30 satellites total
B. 12 hrs correct answers How long does it take to complete orbit for a GPS?
A. 10hrs
B. 12hrs
, C. 8hrs
False correct answers GIS is a computerized system for making maps.
False correct answers GIS is a tool for storing maps and pictures.
True correct answers GIS is a computer based system to store, manipulate, and output
geographical data
False correct answers GPS units used by the military have higher PDOP than normal GPS units
False correct answers GPS works better during the day, when the clouds help improve the
signals.
False correct answers GPS cannot work at all in the forests, even if the canopy is sparse.
False correct answers The signals we obtain with normal GPS today contain random error
introduced by the military.
True correct answers Post processing requires a special kind of GPS called differential GPS
False. UTM not Cartesian correct answers Measurements of Cartesian coordinates are in meters.
True correct answers Measurements of geographic coordinates are in degrees
True correct answers DOQQs are digital aerial photographs
True correct answers A raster model consists of pixels and therefore can require a large amount
of storage.
True correct answers A vector model consists of objects (points, lines, and polygons) that take up
less storage.
True correct answers Metadata are a huge database that consists of both vector and raster models.
False correct answers Selective availability allows the GPS user to select the proper frequency
(L1 or L2 )
Measure distance and direction from a known location to an object of intrest correct answers
What are measurement offsets?
< or = 1 correct answers What range should you ideally attempt to maintain PDOP within?
Post processing correct answers The process of first collecting GPS data in the field and later
applying corrections to those data is often termed________________.
