1, the contents of surveying and mapping training generally include the basic theoretical knowledge of surveying and mapping, the operation of surveying and mapping instruments such as leveling instrument, leveling instrument, total station and GPS-RTK, and the learning of software such as CASS/ FIFTER, surveyor, road star, engineering star, FIFTER and adjustment easy. , as well as professional skills and practical content.
2. The basic theory of surveying and mapping is to have a preliminary understanding of surveying and mapping, so that we can use our powerful theoretical knowledge to solve various problems in practical projects.
3. Instrument operation: leveling: copying elevation, turning point, settlement observation, leveling route mapping, etc. ; Theodolite: measure angle, penetration center, penetration axis, verticality, etc. Total station: coordinate lofting (setting out, houses and places), coordinate mapping, rear intersection, coordinate traverse mapping, section mapping, area mapping, edge mapping, etc.
GPS-RTK: working principle, working mode, lofting, surveying and mapping coordinates, section design, dynamic and static data 4. Processing, road data processing and lofting.
4. Professional skills: traverse surveying and mapping, road surveying and mapping, curve element table, the characteristics and calculation of various curves, road widening and superelevation, broken orthogonal bridge and culvert pipelines, leveling surveying and mapping, angle surveying and mapping, distance surveying and mapping, coordinate surveying and mapping, lofting surveying and mapping, edge surveying and mapping, hanging height surveying and mapping, area surveying and mapping, rear intersection, data acquisition, etc.
5. Internship content: land setting-out, excavation line, retaining wall foundation, ditch, middle edge of highway, earthwork survey, earthwork calculation, piling, culvert placement, traverse adjustment, coordinate calculation, RTK static and dynamic, data solution, leveling surveying and mapping, surveying and mapping data filling, settlement observation, instrument detection and correction, etc.
