Land surveying is a vital discipline that involves locating and measuring features on land. This is done using mathematics and science. Surveyors utilize various land surveying equipment to measure elements. The different aspects that are measured are elevation, angles, and boundaries. Different types of land surveys serve specific purposes. They require distinct tools for accurate and reliable results. These days drones are becoming very useful for surveying land.
1. ALTA/ACSM Survey for Land Survey:
The ALTA/ACSM survey serves the purpose of providing title companies and lenders with crucial location and survey data. This is necessary for issuing insurance policies. This comprehensive land survey for property covers all features and characteristics. It offers a detailed representation of existing improvements in property boundaries.

2. Boundary Survey
A boundary survey is essential for locating the corners and boundary lines of a parcel of land. This type of survey involves both record and field research. It requires accurate measurements and computations to set the boundary lines according to applicable state laws. A boundary survey may also include identifying easement lines and encroachments.

3. Construction Survey
Construction surveys involve staking out structures on a property, such as walls, buildings, roads, and utilities. These surveys provide construction personnel with precise directions for implementing improvements shown in development plans. Construction surveys may also include horizontal and vertical grading and As-Built surveys.

Spectra Precision Laser Level LL500: This long-range, extremely accurate leveling device is stable and reliable. It is suitable for use across the entire survey site.
6. Subdivision Survey
A subdivision survey is used to divide a parcel of land into smaller tracts, lots, or estates. This survey is also employed to design streets and drainages and must be recorded by local and state government agencies.
Recommended Products:
Sokkia SDL30 Digital Level 32x: A digital level suitable for all environments. The SDL30 is highly accurate in measuring both height and distance. Its results are immediately indicated on the LCD.
SECO Thumb-Release Prism Pole Tripod: Ideal for mounting digital levels and other surveying equipment. This tripod is durable. It features a thumb-action release-and-lock mechanism, and each leg adjusts independently up to 6 feet.
7. Topographic Survey
The purpose of a topographic land survey is to locate both natural and man-made topographic features on a parcel of land. Examples include fences, utilities, buildings, elevations, streams, trees, improvements, and contours. This survey is often used by architects and engineers for planning site improvements and developments.
Recommended Products:
SECO Topo Shoe & Point Combo w/ Pin: This combo allows easy conversions from “control” to “topo” surveys. The point comes through the topo shoe to give a consistent elevation on the rod height.
Council Tools 16″ Double Edge Ditch Bank Blade: The 16-inch blade is fastened to a 36-inch handle and made from high-carbon hot-rolled American strip steel. Each survey type has unique requirements, emphasizing the importance of having the right tools for accurate measurements and results
Common Uses of Drones in Surveying and Mapping
Base Mapping/Preliminary Site Assessment:
Drones are employed to collect imagery and topographic relief. This information is useful for development, planning, or construction purposes.
ALTA Surveys:
Drones, in combination with software like PIX 4D/PIX 4D Survey and AIRworks, can reduce the cost of large ALTA surveys. They do this by flying over the site and drawing in features, reducing manual measurements and CAD hours.
Stockpile Monitoring:
Drone-based volume measurement offers a faster, more accurate, and cost-effective method for stockpile monitoring. It replaces traditional methods that involve climbing stockpiles to generate GPS data.
Conclusion:
Land surveying equipment plays an important role in mapping and measuring features on land. The integration of drones in mapping and surveying enhances speed, cost-effectiveness, and safety. All this makes them a valuable asset in the surveyor’s toolkit. For all types of drones contact Canada Sky Drone Services.
