Elementary Surveying
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 |
