1. Two property tax concepts Principle of universality and principle of uniformity
2. State legislation What gives the authority to impose a property tax by a city,
town, or county governing body
3. Three approaches to value Sales comparison, income approach, and cost approach
4. Benchmarks Control points identified by ground targets
5. State Plane Coordinate System A coordinate system designed to provide a common,
uniquely statewide reference system to surveyors, cadastral
mappers, and GIS technicians
6. State Plane Coordinate System Provides a means, through mathematical projections, for
precise conversions of latitude and longitudes into X and
Y coordinates from an assigned false origin (xx=00,yy=00)
for each state
7. GPS receiver is used to deter- Computing the difference between when a signal is sent
mine its position on the earth's from one of the satellites and the time it reaches the re-
surface by.. ceiver.
8. Drift, Crap, and Tilt Three flight inconsistencies
9. Drift Wind associated with high-pressure weather systems that
moves an aircraft off its intended flight path
10. Crab The horizontal displacement, or twisting, of a photograph
from the flight line axis caused when the pilot turns the
aircraft into the wind to stay on the flight line
11. Tilt A condition in which the aircraft rotates around the X or Y
axis

12. Aero triangulation Determines the X, Y, and Z coordinate value of terrain points
using aerial photography
13. Utilizes airborne GPS obtained Aero triangulation
for each photo center (principle
point) during the mission and
the GCP (ground control target-
ed benchmarks) surveyed in the
ground
14. Orthophotograph An aerial photograph that has been geometrically correct-
ed (orthorectified).
15. Oblique images Taken at an angle of 45 degrees to the nadir axis
16. X, y, and z Three ground coordinates of surface features recorded by
LIDAR sensors
17. Precedence of calls Possession, Senior rights, Survey plan, monuments (natur-
al then manmade), direction/distance, area/acreage
18. Direction of a property line The horizontal angle between a line and an arbitrary refer-
ence line called a meridian
19. Magnetic declination The horizontal angle from the true north to the magnetic
north
20. East - add, west - subtract How to convert magnetic bearings to true bearings in north
21. East - subtract, west - add How to convert magnetic bearings to true bearings in south
22. Point of curvature (PC) The point at which the curve begins
23. Tangent distance (T)
