FUNDAMENTALS OF SURVEYING WHAT IS SURVEYING ??? WHAT IS SURVEYING ??? WHAT IS SURVEYING ??? WHAT IS SURVEYING ??? WHAT IS SURVEYING ??? TWO TYPES OF SURVEYING 1 2 TWO TYPES OF SURVEYING PLANE SURVEYING 2 1 TWO TYPES OF SURVEYING PLANE SURVEYING 1 GEODETIC SURVEYING 2 TWO TYPES OF SURVEYING PLANE SURVEYING 2 1 Type of surveying in which the mean surface of the Earth is considered as a plane, its spheroidal shape is neglected. TWO TYPES OF SURVEYING 1 Type of surveying which takes into account the shape of the Earth. Employs the principle of geodesy, which is of high precision & extends over large areas. GEODETIC SURVEYING 2 OPERATIONS OF SURVEYING OPERATIONS OF SURVEYING 1. ROUTE SURVEYING - Highways, railroads, canals, transmission lines and pipelines. OPERATIONS OF SURVEYING 1. ROUTE SURVEYING - a survey for determining the route of a proposed pipeline, power line, cable, road or other linear facilities in order to acquire a right-of-way, servitude or easement from the property owner being crossed. OPERATIONS OF SURVEYING 2. HYDROGRAPHIC SURVEYING - Survey bodies of water for navigation, water supply, or sub aqueous construction. OPERATIONS OF SURVEYING 2. HYDROGRAPHIC SURVEYING is an important civil engineering service that determines the physical features of an underwater area. Like topographic or land surveys, these surveys use special equipment to measure and define a body of water to support marine construction. OPERATIONS OF SURVEYING 3. MINE SURVEYING - Makes use of the principles of land, topographic, & route surveying w/ modifications necessary by altered conditions. OPERATIONS OF SURVEYING 3. MINE SURVEYING - is the practice of determining the relative positions of points on or beneath the surface of the earth by direct or indirect measurements of distance, direction & elevation. -Mine surveyors are responsible for maintaining an accurate plan of the mine as a whole and will update maps of the surface layout to account for new buildings and other structures, as well as surveying the underground mine workings in order to keep a record of the mining operation. OPERATIONS OF SURVEYING 4. CADASTRAL SURVEYING - Made for the purpose of locating property lines & improvement for the use of extent, value, ownership, & transfer of land. OPERATIONS OF SURVEYING 4. CADASTRAL SURVEYING - is the discipline of land surveying that relates to the definition or re-establishment of land parcel boundaries. - involves interpreting and advising on: boundary locations. the status of land, and. the rights, restrictions and interests in property. OPERATIONS OF SURVEYING 5. CITY SURVEYING - Frequently applied on laying out lots for the construction of streets, water supply system, & sewers. OPERATIONS OF SURVEYING 5. CITY SURVEYING - an elaborate survey carried out in an area administered by a municipal corporation. It is conducted when extensive infrastructure improvements are required in an area. This survey helps to draw maps to know boundaries and locate public utilities. OPERATIONS OF SURVEYING OPERATIONS OF SURVEYING 6. PHOTOGRAMMETRIC SURVEYING - The science of measurement by means of photographs. OPERATIONS OF SURVEYING 6. PHOTOGRAMMETRIC SURVEYING - Photogrammetric survey is the process that detects an object, a construction or the surrounding environment. The aim is to obtain a three-dimensional model that will be useful for determining shape and extracting measurements, but above all for the generation of a BIM model. OPERATIONS OF SURVEYING 7. CONSTRUCTION SURVEYING - Employs the use of surveying methods & instruments in construction works. OPERATIONS OF SURVEYING 7. CONSTRUCTION SURVEYING - (otherwise known as "staking", "stake-out", "lay-out", "settingout") is to provide dimensional control for all stages of construction work, including the stake out of reference points and markers that will guide the construction of new structures such as roads, rail, or buildings. These markers are usually staked out according to a suitable coordinate system selected for the project.
