GEOMATICS HW 1 Flashcards
What are the 2 types of surveys?
Geodetic, and plane surveys
what is a geodetic survey?
large scale surveys that account for the earth’s curvature
what is a plane survey
a plane survey for smaller land that neglected the earth’s curvature
list all the common civil engineering surveys?
land
topographic
route
city/municipal
construction
hydroprahic
marine
mine
forestry
photogrammetric
as built
reference
what are the land surveys?
they measure the boundaires and features of a property to determine onwership or divide land within construction
what are topographic survey?
these map the elevation and natural features of a land area, such as hills, valleys, man-made structures to help plan construction projects.
what are route surveys ?
these are used for designing transportation routes like roads or railways, focusing on the land along the routes’ path.
what are city aka municipal surveys?
these deal with surveying areas within cities or towns, often used for planning infrastructure like streets, utilities, and public works.
what are construction surveys
basically mapping out the blueprint on the ground.
marine survey
these are for larger bodies of water, like oceans and seas. used for undersea cables and offshore construction
hydrographic survey
mapping out bodies of water and anything related to the water. it provides the details needed for safe navigation, or construction near that body of water.
what is a mine survey
focus on mapping underground or open-pit mines to guide the safe extraction of minerals.
forestry survey
measures forest land, often for conservation, logging, or managing natural resources
photogrammetric survey
areal pics to create maps and models of land, for large scale projects or areas difficult to access.
as built survey
conducted after a construction project is done to make sure the construction match the original plan
