leveling surveying procedure

Topographic Surveying - University of ReginaThe desired level of accuracy depends on the intended us of the survey data (e.g. locating permanent stations or surveying bridges and dams versus surveying for terrain analysis or orienteering). For topographic mapping, the desired level accuracy is the plottable error, the shortest distance that can be depicted on a map at a given scale.PPT – Introduction to Surveying BPD LEVELLING PROCEDURES ...Always commence and finish a level run on a Benchmark (BM or TBM) Keep foresight and backsight distances as equal as possible ; Keep lines of sight short (normally lt 50m) Never read below 0.5m on a staff (refraction) Use stable, well defined change points; 16 Levelling procedures.

Prelimunary 8/99 SURVEY REPORT

Before initiating the leveling survey, a "demonstration" survey is required of each crew to validate their assigned equipment is operating correctly and the crew understands this "Leveling Specification and Procedures". A collimation test is to be performed prior to the demonstration surveying.FACULTY OF CIVIL ENGINEERING & EARTH RESOURCES .The heights (Reduced level or elevation) of the points are referred to some horizontal plane of reference called the datum (universally employed Mean sea level). In surveying, these heights are found by leveling. Leveling is the procedure used when one is determining differences in elevation between points that are remote from each other.Survey — Colorado Department of TransportationThe purpose of the CDOT Survey Manual is to define the minimum specifications that shall be followed while performing surveys for CDOT in order to secure an optimum degree of statewide uniformity, to establish and maintain survey standards, and to improve the overall efficiency of CDOT's survey functions.
