Errors in topography, what they are and what we do to avoid them

como evitamos errores en topografia

In topography, as in any other human activity, failures and errors can arise due to human factors, environmental conditions, system failures, or previously gathered information that was not corroborated.

At Acero Estudio, a company specialized in topographic services, we are fully aware that errors will always occur, but we have tools to detect and correct them promptly, especially since many large-scale works and projects depend on our topographic surveys.

In this regard, we have identified the following types of errors:

  1. Human Errors: These can occur due to poor environmental conditions that affect perception or factors that can temporarily affect the person (such as illness, headaches, or others).To avoid this type of error, we have a data verification protocol where, through a random sample of points, we can determine the accuracy of the study. If the pattern remains within the expected parameters with a minimal level of error, the information is validated; otherwise, the data collection may need to be redone.
  2. System Errors: Sometimes, a system failure, misconfiguration, or loss of proper calibration can lead to incorrect data collection. This is very dangerous but also detectable through protocols where different measurement methods are used, which should result in similar outcomes, allowing us to quickly identify any discrepancies.
  3. Unpredictable Errors: These types of errors are difficult to detect and infrequent. However, with data verification protocols, it is possible to find them quickly.

Triangulation is a traditional surveying technique that allows us to measure distances and angles on the Earth’s surface. However, it has been gradually replaced by more modern surveying techniques that utilize GNSS technology, drone surveying, etc.

Although the use of traditional surveying has decreased, it is still necessary in some cases where satellite technology is absent or where population density requires it. Here are some key points on the importance of topographic triangulation:

Provides Accuracy in Measurement

This technique allows us to measure distances from the projected vertices of triangles and calculates the sides using trigonometric formulas. This type of measurement is ideal for large areas in construction projects, agriculture, or urban planning that require precise data.

Allows for Defining Control Points

Through triangulation, it is possible to define geodetic control points that will be useful for future measurements. These points are also highly useful as references for integration with previous work in a unified system.

Covers Large Areas

As mentioned, there are more modern techniques for developing large areas than triangulation (check our surveying services); however, in cases where technology is lacking, triangulation is particularly useful for studying large tracts of land.

Serves as a Basis for Navigation Systems

The technique of triangulation has been fundamental in the development of both terrestrial and maritime navigation systems. Even today, in the GPS era, triangulation continues to be used for the calibration and verification of these systems.

Applications in Geodesy and New Technologies

Geometric triangulation measurements can be integrated into geodetic systems, making them ideal for cartography and the development of scientific knowledge related to plate tectonics and geophysics.

Additionally, remember that triangulation adapts well to integration with new technologies such as GPS, drones, and geographic information systems, further improving the precision and efficiency of topographic surveys.

Factors to Evaluate Before Conducting a Topographic Survey

factors in topografia

Conducting a topographic survey requires flexibility and adaptation. In addition to having experience, the surveying team must undertake proper planning, select the right technology, and schedule a work scheme according to the objectives of each project.

Below, we will explore the factors that influence the execution of a topographic survey. Always remember that these guidelines are relative, and while we attempt to generalize them for study purposes, nature almost always has more than one capricious characteristic that will require the ingenuity and initiative of the survey teams in charge.

Vegetation Factor

The density of vegetation is a crucial factor in conducting a topographic survey. In densely vegetated areas such as forests or jungles, carrying out a topographic survey becomes an arduous task.

Similarly, ground cover such as grass or weeds affects data accuracy. Trees, both coniferous and deciduous, can complicate the use of aerial sensors since the density of the cover and the resolution of the required product will determine the technology to be used. Acero Estudio suggests the use of LIDAR for greater accuracy in results.

Construction Factor

Houses, buildings, bridges, overpasses, and other man-made structures affect a topographic survey because they obscure natural terrain features such as slopes and water runoff areas.

Surveyors must use photogrammetric techniques in areas with constructions. It is worth noting that in areas with tall buildings and little space between them, it is more complicated due to the greater overlap of images.

Water Factor

The presence of water in the study area demands the use of specialized technology. In some cases, LIDAR is recommended; however, this technology has certain limitations beyond a certain depth. Additionally, in some places, the coastline changes throughout the day, hindering the work.

Besides the factors imposed by nature, there are other intrinsic factors of the surveying discipline that can present challenges.

Technology Precision Limitations

Not all instruments are suitable for all areas or conditions. For example, drone surveying can be inaccurate in densely vegetated areas where LIDAR technology is more recommended.

Instrument Position Accuracy

This factor is influenced by the experience of the surveying team, who must handle the instruments proficiently. These “flight hours” will impact the quality and accuracy of the survey, as well as the speed of completion.
