Answer :
The types of survey functions that cannot be performed with the given equipment are 1. high precision level circuit and 4. trigonometric leveling.
The total station, prism pole, and prism are essential instruments for many surveying tasks. They allow for accurate measurements of angles, distances, and elevations. However, there are certain functions that require additional equipment not present in this scenario.
1. High precision level circuit: This type of surveying function involves establishing a precise level reference across a large area or a construction site. It requires the use of a high-precision level instrument, such as an automatic level or a digital level, which can provide accurate and consistent elevation readings. The equipment loaded in the truck, namely the total station, prism pole, and prism, does not include the necessary instrument for this particular task.
2. Radial stakeout for construction: Radial stakeout is a common surveying function used in construction projects to determine the location and layout of structures, roads, or utilities.
It involves setting out points along a radial path from a central point. Although the total station, prism pole, and prism can be used for stakeout tasks, additional equipment like a reflectorless total station or a GPS receiver would be required for accurate radial stakeout.
3. Set lot corners: This function can be performed with the given equipment. The total station allows for precise angle measurements, and the prism pole and prism enable distance measurements. By setting up the total station at one corner of the lot and using the prism pole and prism to measure distances and angles, the surveyor can accurately set the remaining lot corners.
4. Trigonometric leveling: Trigonometric leveling is a method used to determine height differences between different points without using a traditional leveling instrument.
It relies on measuring angles and distances to calculate elevations. However, this technique requires specialized software and calculations, which are not feasible with the given equipment alone.
In conclusion, the types of surveying functions that cannot be performed with the equipment loaded in the truck are high precision level circuit and trigonometric leveling. These functions require additional instruments or software not present in the given scenario.
