LESSON 1 Flashcards
- Art of measuring horizontal and vertical distance
Surveying
-Measuring angles between lines
* Determining the direction of lines
Surveying
Establishing points by predetermined angular and linear
measurements
Surveying
portrayed graphically by the construction of maps, profiles,
cross sections, and diagrams
Survey Data
science of accurately measuring and understanding the earth’s
geometric shape, orientation in space, and the gravity field
Geodesy
Computer and software
tools for gathering and
analyzing data connected
to geographic locations
and their relation to
human or natural activity on Earth
Geographic Information System (GIS)
A computer system that
analyzes and displays
geographically
referenced information
particularly products of
Surveying
Geographic Information System (GIS)
A space-based radio navigation system consisting of a constellation of satellites
broadcasting navigation
signals and a network of
ground stations and satellite control stations used for monitoring and control.
Global Positioning System (GPS)
Bathymetric Survey, sometimes referred to as a fathometruc
survey, is a type of hydrographic (water-based) survey that maps the depths and shapes of underwater terrain to illustrate the land that lies
Hydrography
Science of obtaining the physical properties of an area without being there. It allows users to capture, visualize, and analyze objects and features on the Earth’s Surface. By collecting imagery; we can classify it into land cover and other types of analyses.
Remote Sensing
Remote sensing can be done through LIDAR (____) and
SONAR (____)
Light detection and ranging
Sound navigation and ranging
The science and
technology of making
measurements using
photographs
Photogrammetry
- Making a map or a matching process where the points of one set are match against the points of another set.
- A map is a symbolic representation of a space that emphasizes linkages between things, areas, or themes. Many maps are static, meaning they are set to paper or another lasting media, although others are dynamic and interactive. Mapping also involves the action of a proposed plan for positioning or setting the positions of a
designed feature.

Main disciplines of surveying
Land Surveying
Engineering Surveying
Mining Surveying
Hydrographic Surveying
Geodetic Surveying
Photogrammetry and Remote Sensing
the survey of bodies of water made for the purpose of
navigation, water supply, or sub-aqueous construction
Hydrographic Survey
this generally involve imaging or “mapping” of
regions of the sky using telescopes
Astronomical Survey
refers to those control, topographic, and construction surveys
necessary for the location and construction of highways, railroads, canals,
transmission lines, and pipeline
Route Survey
made to determine the length and direction of land lines
and to establish the position of these lines on the ground
Boundary Survey
made to gather data to produce a topographic map
showing the configuration of the terrain and the location of natural and man
made objects
Topographic Survey
made to control, locate and map underground and surface
works related to mining operations
Mining Survey
made to establish te horizontal and vertical positions of
arbitrary points.
Control Survey
made to lay out, locate and monitor public and private
engineering works
Construction Survey
made to utilize the principles of aerial
photogrammetry, in which measurements made on photographs are used to
determine the positions of photographed objects
Photogrammetric Survey
