Question

True or false:

1. The Lambert Conical projection would be preferred to the Transverse Mercator projection for establishing a Cartesian coordinate system for the state of Virginia.

2. When performing differential leveling, the earth's curvature results in rod readings that are too low

3. States along the eastern seaboard of the U.S. typically do adhere to the Public Land Survey System, whereas western U.S. states typically employ a different means of land administration and transfer that is often derived from old English law.

4. It is possible to adjust a closed-figure traverse without knowing the coordinates of any of the traverse stations (in other words, we could arbitrarily assign coordinates to one of the stations and compute the subsequent station coordinates).

5. Generally, angles measured along very long lines of sight are less accurate than those measured along much shorter lines.

Answer 1

1)True - Lambert conical projection is used for establishing Cartesian coordinate system in the USA in standard parallels,37 degree N and 65 degree N .

2)False - The earth's curvature results in rod readings are too high while performing differential leveling.

3)True - Some states that are not under the Public land survey are California , Hawaii and New Mexico.

4)False - The points in a closed figure traverse or the stations should be known to avoid errors.

5)True- The angles measures along shorter lines of sight are more accurate .
