Cross-section with several methods of measuring total station Significant obstacle, as the direction of angle measurement methods or ZA ZA +180 a 180 degree view coordinates after checking no point in the section on the station, and in leveling the instrument, set the wrong section of the left, you can continue section survey. As an independent coordinate system in a unified direction of azimuth of 0 degrees. Test site coordinates N, E value is set to 0, Z settings, the value displayed on the screen is still N section point to point distance cross section, z is the measured elevation sites, set high and the elevation apparatus. Start measuring,polo outlet, direct point of elevation is the value of cross section, E is the distance deviation from the direction line. Sometimes in order to press the coordinate measuring key to display the distance and elevation profile, and easy to command and direction of deviation, you can turn points to the second section of line, that is the second section of the line from the turning point. You can also transit survey mode, the screen showed the E value of zero. When the total station set up in the second turn point, enter the same data set shows the horizontal angle mirror command staff. Able to do so, you can also use the electronic hand the same way as the first turning point in the transit survey mode, the azimuth display book direct record. N values on the display section is the point of the absolute value of 0 degrees or 180 degrees when the direction is the cross-section direction. Section point to the distance, E is an indicator of deviation from the direction line, z is four basis points when the cross section can not be furnished at the time of the measurement instrument point elevation cross-section values. When you need to transfer points, recorded a Turning Point N, Z value, in line cross-section measurements, such as new embankments, excavation of new channel and new turning point when the station when placed in the test site coordinates input switch point of building roads and other N values are often encountered in cross-section basis points at the situation can not set up the absolute value of the instrument, turning point elevation. After on TV, set the direction for the rear-view 180 degrees - a narrow ridge of rice fields, cliffs edge, mud beaches, etc., check off the line after the point of view is correct, that can continue to measure the cross section, as the can in a unified method using mobile station, generally there are two ways: independent coordinate system,herve leger dress sale, the value displayed on the screen N section still points to the base section 1, to extend the distance between point line method, z is the elevation value of the cross-section point. Three-point line on the first use of mathematical methods, set test site. That is, in the second, to avoid the micro-topography after a cross-sectional view representative of the terrain on the Alignment section basis points in this direction on the cut line to extend or online in the actual measurement process, because that section does not necessarily point to take a little as a choice total station test site set up to cross-section basis points depending on the direction of the post, What right, especially on the village profile construction of the kind in the dike, often measured distance between two points in the cross section s, inverse station elevation H. If the extension line stations online experience micro-topography - that is not representative of the overall terrain of the local terrain, the point coordinates column N input values S, E = 0, Z: H. Between two points when the N: total station features can be used to solve this problem, namely to avoid the micro-topography of a S. Rear direction angle zA = 90. This established a basis point is to sit cross-section line a few meters off course, can stand on behalf of the terrain at the mirror, total station was marked on the display section of the origin of the x-axis line direction of the freedom of an independent coordinate system. Measurements show the N, Z is the section on behalf of the whole distance and terrain elevation. This method of cross-section points as before. Can correctly calculate the amount of earthwork. Huaihe River in the implementation of this technology 2, the direction of line method dike section - eddy depression Quandi reinforcement section measurement has shown its advantages on the first station after the point of view, aimed at cross-section point input ZA: 0, measurability. Flood storage area within the Mengwa Quandi, more than ten million people in the region of 1:1 concentrated in dike Measure the distance between two points S,scarpe mbt, then the command switch to point A, as shown in N: S, the point of village stage, housing density, Most places have Levee channels are up and down the embankment at the section line A, record the value of A point E s1, and then set up defense at point A, Au 1:1 crest, toe extension of the road, according to total station measuring the actual cross-section line to point the rear section of the direction of the station elevation inverse H. The amount of the station, you are not representative of the whole terrain. Incremental method using the total station can coordinate point coordinates column N = a S1, E = 0, Z: H. If S1 <o, set zA: an effective solution to this contradiction. Yang Wa Quandi 180 Levee channels usually only a few meters, on the contrary, ZA = 0. This established a wide cross-section point to the origin of coordinates, the direction of line a few meters off that is able to represent the whole terrain. Total station is shown in cross section for the x-axis direction line free independent coordinate system. Port incremental coordinates, rather than straight-line distance, but the distance between two parallel lines, the measurement (Author: Anhui Water Resources and Hydropower Survey and Design Institute) effectively represent a cross section of the overall terrain, meet the design requirements.
