programs permit “welding” surfaces together, while others require that the user specify the number of equidistant vertices used to form the mesh. The spacing can be altered so that a vertex may be snapped to the vertex of an adjacent surface to ensure a tight joint. TASK3 31

Surveying T.Pavaruban J/CE/14/04/18 3.1. Describe the benefits of computer software to solve typical surveying problems. T oday’s surveying environment is changing fast; new technology emerges at frequent intervals, increasing the volume and variety of data that you need to contend with. Surveying instruments —GPS, total stations, and digital levels— are used together to provide data for surveying projects, and you have to cope with all of the data. Trimble’s powerful Terramodel software is an integral component of the Trimble Office software suite. The system provides a complete solution for survey data processing, site and infrastructure design, plus construction project data management. Used internationally by surveyors, engineers, and contractors alike, Terramodel seamlessly communicates with all Trimble instruments and data collectors, as well as many third party data collection systems, design software, and CAD packages, to provide you with all the flexibility you need in today’s changing world Computer systems To be economically viable, practically all major engineering/surveying organizations use an automated plotting system. Very often the total station and data logger are purchased along with the computer hardware and software as a total operating system. In this way interface and adaptation problems are precluded. Figure 1.11 shows a computer driven plotter which is networked to the system and located separately. The essential characteristics of such a system are: (1) Capability to accept, store, transfer, process and manage field data that is input manually or directly from an interfaced data logger (Figure 1.12). (2) Software and hardware are in modular form for easy access. (3) Software will use all modern facilities, such as ‘windows’, different color and interactive screen graphics, to make the process user friendly. (4) Continuous data flow from field data to finished plan. (5) Appropriate database facility for the storage and management of coordinate and cartographic data necessary for the production of DGMs and land/geographic information systems. (6) Extensive computer storage facility. 32

To be truly economical, the field data, including appropriate coding of the various types of detail, should be captured and stored by single-key operation, on a data logger inter faced to a total station.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
