This course is limited to ground-based survey methods, specifically, georeferenced observations taken from survey instruments set up on tripods or fixed control points. |

True |
|
|
False |
| 2. |
In general map scales greater than 1 inch = 100 ft are intended for detailed design purposes. Smaller scales between than 1 inch = 100 ft. and 1 inch = 1000 ft are used for general planning purposes. |

As build surveys are surveys compiled to show actual condition of completed projects as they exist for record purposes and /or payment. |

An engineering site plan survey is topographic ) and, if necessary, hydrographic) survey from which a project is conceived, justified, designed, and build. |

Control surveys are performed to establish monumented references system for military or civil facility mapping projects. These fixed horizontal control points and vertical bench marks are then used as |
|
|
Starting points for supplemental topographic site plan mapping. |
|
|
Monumental points. |

A traverse survey is defined as the measurement of the lengths and directions of a series of _____________________ on earth. Points connected by the lines of a traverse are knowns as traverse stations. |
|
|
Straight lines connecting a series of points |
|
|
Straight lines connecting a series of stations |

Vertical control surveys provide a basic frame work for controlling elevations on facility mapping projects. |
|
|
True |
|
|
False |
| 9. |
The purpose of vertical control surveys is to establish |
|
|
elevations on rigid benchmarks throughout the project area. |
|
|
The height of the reference point. |

Construction plans, maps, facility plans, and CADD/GIS database are created by a variety of terrestrial satellite, acoustic, or aerial mapping techniques that acquire planimetric, topographic, hydrographic, or feature attribute data. |

False |

Topographic surveys can be performed on any coordinate system. Most localized total station topographic surveys are initiated on (or referenced to ) an arbitrary coordinate grid system. , e.g. X= 5000 ft, Y= 5000 ft., Z= 100 ft, |
|
|
and often elevation or scale reductions are ignored. |

The discipline of surveying consists of locating points of interest on the surface of the earth. The positions of points of interest are defined by coordinate values that are referenced to a predefined mathematical surface. In geodetic surveying this mathematical service is called a datum, and the position of a point with respect to the datum is defined by its coordinate. |
|
|
True |
|
|
False |
| 14. |
State Plane Coordinate Systems (SPCS) were developed by the national Geodetic Survey (NGS) to provide |
|
|
plane coordinates over limited region of the earth’s surface. |
|
|
The GPS system |
| 15. |
Universal Transverse Mercator (UTM) coordinates are used in surveying and mapping when |
|
|
The size of the project extends though several state plane zones or projections. |
|
|
For small projects |
| 16. |
Most linear engineering and construction projects ( roads, railways, canals, navigation channels, levees, flood walls, beach renourishments, etc. are locally referenced |

Whenever necessary, permission to enter a military or private property maybe acquired by the District prior to entering such property. While on the military installation, members of the survey crew will adhere to all of the stipulations (e.g. rules, regulations, directives, verbal guidance, etc,) set forth by the installation commander or his designated representative. |
|
|
The same basic guidelines are applicable when entering a private property. |

Field survey notes can be collected either manually or electronically. Manual methods include field books or plane table sheets. |
|
|
True |
|
|
False |
| 19. |
Electronic methods include |
|
|
both internal and external data collectors interfaced with various survey instruments (total station, GPS receiver, or Lidar) |
|
|
external data collectors only |
| 20. |
The most common type is a combination form, but an experienced recorder selects the version best fitted to the job at hand. The location of a reference point |
|
|
maybe difficult to identify without a sketch, but often a few lines of description are enough. |
|
|
Needs to be researched thoroughly. |
