The purpose of levelling is to determine the relative heights of points of interest on the surface of earth. Thus, it involves measurements of distances in a vertical plane like distances in horizontal planes were measured in chain surveying.
1. OLDER TOPOGRAPHIC SURVEYING METHODS. This section provides an overview of the past and present instruments and methods used to perform topographic surveys of sites, facilities, or infrastructure. Prior to the advent of total stations, GPS, LIDAR, and data collector systems, transit and plane table topographic surveying methods and
1. PURPOSE. This discussion sets forth accuracy standards and other related criteria that are recommended for use in large scale site plan topographic surveys for engineering and construction purposes.
Control point surveying is a surveying to establish the reference point network, and is also to determine the coordinates of a new point based on the reference point network. Some precise measuring instruments such as total station and level are used for the surveying.
This book covers a wide range of measurement techniques, from land surveying, GPS/GNSS and remote sensing to the associated data processing, the underlying coordinate reference systems, as well as the analysis and visualization of the acquired geospatial information.
This book provides an introduction, at academic level, into the field of surveying and mapping. The book has been compiled based on hand-outs and readers written for the third-year course Surveying and Mapping, in the bachelor program Civil Engineering at Delft University of Technology.
