Products for Surveyors and Engineers

Surveying is one of the oldest professions, with records of land surveys dating back to ancient Roman times. The ancient measuring tools for surveying were already developed with surprising accuracy. Romans used an instrument called a groma to “trace on the ground simple and orthogonal alignments necessary to the construction of roads, city, temples, and agricultural lands subdivision.” Since then, surveying instruments have evolved with respect to exponential developments in technology. Today, surveyors use precise electronic equipment in addition to more basic tools to aid in measuring and mapping efforts. Here is the list of the most surveying tools, including:

  • Level and rod: A graduated wooden or aluminum rod, used with a levelling instrument to determine the difference in height between points or heights of points above a vertical datum. This tool is used to establish and verify elevations.
  • Theodolite and Total Station: A theodolite is a surveying instrument with a rotating telescope for measuring horizontal and vertical angles to make precise measurements of areas and triangulate the position of objects in a specific area. A total station is a theodolite with distance measuring capability and on-board computer to collect data and perform triangulation calculations. This tool is used to record features in topographic surveying or to set out features such as roads, houses, or boundaries.
  • Measuring tape/wheel: A length of tape or thin flexible metal, marked at intervals for measuring size or distance.
  • 3D scanners: A surveying instrument that can accurately measure and collect data from objects, surfaces, buildings, and landscapes. This tool collects information in the form of point cloud data, which consists of millions of 3D coordinates. These coordinates can be used to create 3D computer-aided design (CAD) models, which can then help analyze topographic features and structures. The high accuracy of 3D scanners helps reduce project costs.
  • GPS/GNSS: The use of Global Positioning System signals and/or Global Navigation Satellite System signals via a receiver and antenna to determine the form, boundary, position, objects, or points in space relative to other forms, boundaries, or points. This technology has dramatically increased the speed and productivity of surveyors using on-demand centimeter-level accuracy provided by Real-Time Kinematic (RTK) positioning.

QL Enterprises Inc has been providing all kinds of those devises for surveyors and engineers.
