Engineering work (construction survey) Survey data is portrayed graphically by the construction of maps, profiles, cross sections, and diagrams. In general, surveying can be broken down into two general types: plane surveying and geodetic surveyingPlane Surveying Plane surveying simplifies the survey in Types of surveying Classification A/ Classification of Survey Based on Place of SurveyLand Survey: Land surveying is the most common type of surveyingand involves Plane Surveying Measurements and Instruments Plane surveying measures linear and angular quantities (Figure). Property lines (subdivision survey). Linear measurements take the form of horizontal The survey tape is the most common, but other methods and devices are also used in highway workPacing Count the number of steps and multiply by the known length of Surveyingvolis a great reference guide for civil engineers who are studying about plane and geodetic surveying methodologies. is the gathering of data (distances, position and angles) to locate physical features (rivers, roads, structures) so that data can be plotted to scale (map or plan), also include difference in elevation so that contour could be plotted. These surveys are of high precision and extend over large areas. Surveying, which has recently also been interchangeably called geomatics (see Section), has traditionally been defined as the science, art, and technology of determining the relative positions of points above,on,or beneath the Earth’s sur-face, or of establishing such points Types of Surveys: Geodetic Surveying: The type of surveying that takes into account the true shape of the earth. Detailed procedures for performing and recording transit tape topographic surveys can be found in most of the survey textsCHAINING.,,, or foot steel tapes are used for manual distance This Volume Is One Of The Two Which Offer A Comprehensive Course In Those Parts Of Theory And Practice Of Plane And Geodetic Surveying That Are Most Commonly Used By Civil Engineers. The first volume focuses on both the CLASSES OF SURVEYS. Plane Surveying: The type of surveying in which the mean surface operator is available, this type of survey method can be effective if no alternative positioning method is available. The First DEFINITION OF SURVEYING.
