Elementary Surveying: Ch. 1 Introduction
| Question | Answer |
|---|---|
| As-Built Surveys | document the precise final locations and layouts of engineering works and record any design changes that may have been incorporated into the construction |
| Mine Surveys | performed above and below ground to guide tunneling and other operations associated with mining |
| Solar Surveys | map property boundaries, solar access easements, position obstructions and collectors to sun angles |
| Satellite Surveys | using GPS to determine ground locations |
| Optical Tooling | (industrial surveying) method of making extremely accurate measurements for manufacturing processes where small tolerances are required |
| Ground Surveys | uses measurements made with ground based equiptment |
| Alignment Surveys | made to plan, design and construct highways, railroads, pipelines and other linear projects |
| Ellipsoid | curved surface approximating the size and shape of the earth |
| Plane Surveying | reference based on flat, horizontal surface |
| Retracement Surveys | recover previously established boundary lines |
| Geodetic Surveying | computations based on ellipsoid |
| Plane Surveying | not appropriate for surveys covering extensive areas |
| Geodetic Surveying | earth centered, 3 dimensional earth fixed Cartesian coordinate system |
| Geodetic Surveying | determine relative position of widely spaced monuments |
| Control Surveys | establish a network of horizontal and vertical monuments that serve as a reference framework for initiating other surveys |
| BLM | Bureau of Land Management |
| Bureau of Land Management | general land office responsible for managing the public lands; mostly western states and alaska |
| Land, Boundary, Cadastral Surveys | establish property lines and property corners markers; cadastral is generally applies to public land surveys |
| CORS | Continuously Operating Reference Station |
| Continuously Operating Reference Station | can be downloaded from NGS website for use in GPS survey |
| NGS | National Geodetic Survey |
| National Geodetic Survey | control surveys to establish a network of reference monuments throughout the US |
| ACSM | American Congress on Surveying and Mapping |
| American Congress on Surveying and Mapping | foremost professional surveying organization in US |
| Topographic Surveys | determine locations of natural and artificial features and elevations used in map making |
| Original Surveys | establish new section corners |
| Aerial | accomplished by using photogrammetry or remote sensing |
| GIS | Geographic Information Systems |
| LIS | Land Information Systems |
| GIS/LIS | computer based systems enable storing, integrating, manipulating, analyzing and displaying virtually any type of spatially related information about our environments |
| Subdivision Surveys | establish monuments and delineate new parcels of ownerships |
| Condominium Surveys | provide a legal record of ownership |
| Construction Surveys | provide line, grade, control elevations, horizontal positions, dimensions and configurations for construction operations |
| Hydrographic Surveys | define shorelines and depths of lakes, streams, oceans, reservoirs and other bodies of water |
| USGS | US Geological Survey |
| US Geological Survey | mapping our nations and surveying its resources; nations mapping division produces topographic maps |
| Surveying | also known as Geomatics; the science, art, and technology of determining the relative positions of points above, on, or beneath the Earths surface, or of establishing such points |
