There are two general types of land surveying: plane and geodetic.
Plane surveying considers the earth to be a flat surface--a plane, which works well for jobs spanning a short distance (a few miles), because calculations are relatively simple. Surveys of this nature account for much of survey work being done.
Geodetic surveying takes into account the true shape of the earth. These surveys are usually of a very large scale and most often performed by government agencies. GPS is capable of automatically giving geodetic positions (within certain qualifiers), though a thorough understanding of the principals of geodesy is necessary to adequately design and conduct a geodetic survey.

plane table surveying is a graphically method because filed observations and plotting are done simultaneously.it's most suitable for small mapping
Plain surveying means the survey in which earth surface is considered as to be flat or plain i.e. its curvature is ignored. Geodetic survey is the survey in which curvature of the earth is taken into count and then surveying is done.
The prismatic compass is a type of compass use for survering a land.
Surveying is the back bone of construction projects, we must need surveying before starting a construction project, during execution of construction activities and after completion of project. Before starting project surveying help us in design and calculation of quantities. During execution of construction activities surveying is most important thing, It help us to maintain the exact locations and heights. After completion of project surveying is called topographic surveying and it helps us to prepare the As-Built drawings, to make comparison between design and actual constructed structures, to check the differences.
it is a type of surveying in which we can plot the area in the field rapidly.we can also find our error in the field and solve it.
chain surveying is one of the types of survey methods. It is used to survey short length lands
