In surveying, a bench mark (two words) is a post or other permanent mark established at a known elevation that is used as the basis for measuring the elevation of other topographical points. Witness posts (or marks) can be signs on wooden or metal poles that let the viewer know that a survey marker is located nearby. Surveying Instruments and Their Uses: The main pieces of surveying equipment in use around the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. Since survey markers are frequently small metal disc affixed to the ground in cement or onto rock, witness posts are signs that serve as a visual aid.

For instance, she may place marks at the northeast and southwest corners of a piece of land to physically represent the boundaries. Mean Sea Level Mean sea level is established by taking the average height of tides in the sea over a very long period (generally 19years). In recent times various electronic survey instruments like Total Survey Station are used for collecting all types of survey data. The 0.05 gradation lines are usually longer than the hundredths (0.01) but shorter than the 0.10 marks. Datum line is the reference line with respect to which the levels of other station points are fixed. Not every surveyor will use all the same abbreviations but I hope this guide can help if you are stuck in a similar situation. Examples of azimuths observed from north are shown in Figure 1.

For the topographic survey, it is crucial to use accurate base station coordinates to collect reliable data. Number your traverse stations - the ones that are part of your closed loops - by tens. stationing Setting stakes at specified intervals along a route survey, commencing at the starting hub. Full stations are set at 100-foot intervals. A stake set at a point 50 feet from a full station is known as a half station. station mark See mark (definition 2). As illustrated, they can range from 0 to 360 in value. The total context against which all products are measured and compared is referred to as the benchmark. In its simplest form, the first station would be written as 1+00 and the second station would be written as 2+00. Main station: These are the stations at the beginning or at the end of lines forming main skeleton. The below mentioned objects are Land surveying map symbols which we usually see in surveying maps (example plot map in a city). Then review the gradations. The adjustment must be done so that the head of the tripod lies exactly over the station mark. Common Surveyor Symbols Due to the nature of their work, a surveyor uses numerous physical markings while surveying a property. Mean sea level or MSL is used as datum level for all important surveys of that zone. Mark descriptions are critical information used to positively identify survey control, and to ensure the correct mark has been recovered, along with its corresponding high accuracy coordinate (s), in the NGS database. It can be a trigonometric station, a traverse station, or a control station What is a Survey Station and what should we have looked for? The stations should be eg/ 10, 20, 30, etc. Chain surveying, It is a method of Surveying in which no angles are measured but the only linear measurement is taken in the field by using a. 1-6.
