Lasers and Global Positioning Systems Generally lasers and global positioning system use for setting up building corners and delineating building perimeters so foundation work could start used to rely on string and steel tape measures‚ and were calculated from measurements drawn from the property boundary lines. Lasers and GPS have made that work much more accurate and much faster. Heavy equipment used to rely on the operators to accurately read grade stakes‚ and set equipment blades and buckets

What is a Dumpy or Automatic Level Let us look at the history of surveying levels. Since the Dumpy level was invented in early 1700’s it has been considered the standard‚ that was up until around the 1830’s when the transit level was invented. Recently the level has changed faster than you can keep up with it‚ but through all this the Dumpy level has remained a reliable back up just in case the modern levels breakdown. A dumpy level‚ builder’s auto level‚ leveling instrument or automatic level is

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my

AP 224 QSM 415 Land Surveying Chain Surveying What is chain surveying? Chain surveying is a type of survey in which the surveyor takes measurements in the field and then completes plot calculations and other processes in the office. Here only linear measurements are made i.e. no angular measurements are made. This is most suitable adapted to small plane areas with very few details. If carefully done‚ it gives quite accurate results. The necessary requirements for field work are Chain Tape Ranging

Abstract: The January 1996 event‚ and its damages was used to understand ice jam flooding in the lower Mohawk River. Ice jams are formed when the blocks of ice formed along the river causing water retention behind the blocks of ice. Once the ice melts the water that was retained adds up to the water level already existing. to understand ice jams better the tree elevation scar of the eastern cottonwood tree was measured in the lock 8 in glenville‚ stockade park in schenectady and at the Glen sanders

Abstract This investigation examined the preferred habitat of the prawn Alope spinifrons for the purpose of keeping the prawn in optimum conditions in captivity. The survey took place on shoreline between Matapouri Bay and Wooleys ’ Bay on the Tutukaka Coast. A. spinifrons populations were surveyed‚ water chemistry‚ temperature and depth were noted as well as substrate type and flora and fauna sharing the area. A. spinifrons preferred sheltered rocky areas where there was good water circulation

Annalisa Marino Mr. Winteres English 101 April 4‚ 2012 Can You Find Me Now? How is a Nintendo Wii game console able to determine the location of a Wii Remote while a player interacts with a game? The answer is triangulation‚ a process that determines the location of an object by measuring the angles from two or more fixed points. (Jains‚ Malia‚ 2012‚ pp. 30 - 48). The length of the base line and the two known angles allow a computer or person to determine the location of a third point. Similarly

INTRODUCTION ▪ Two Peg Test is a surveying operation carried out to determine whether the levelling bubble and telescope line of sight are parallel. OBJECTIVE ▪ Peg Test is a surveying operation carried out to determine if the leveling bubble (bubble axis) and telescope line-of-sight (line of collimation) are parallel. THEORY ▪ By using the leveling method‚ work for establishing Temporary Bench Mark (TBM) was done ▪ Bench Mark (BM) must be known first. BM
