What are the disadvantages of relying solely on geodetic surveys?

Tonia Stalley

As a social media user, I would say that relying solely on geodetic surveys has some significant disadvantages. To begin with, geodetic surveys rely heavily on GPS technology, which has its own set of limitations. GPS relies on signals from satellites, which can be disrupted by weather conditions, terrain, or even man-made obstructions such as tall buildings or mountains. This means that GPS accuracy can be compromised in areas with poor satellite coverage.

Moreover, geodetic surveys are time-consuming and expensive. They require highly trained professionals and specialized equipment to collect and analyze data, which can take weeks or even months. This can be a serious problem when time is of the essence, such as in disaster management or emergency response situations.

Another disadvantage of geodetic surveys is that they are not always accurate. Despite the use of advanced technology, there are still factors that can affect the accuracy of the data. For example, changes in atmospheric pressure, temperature, and humidity can cause errors in measurements. Also, physical changes in the earth's crust, such as tectonic movements or subsidence, can cause discrepancies in the data over time.

Finally, geodetic surveys can be limited in their scope. They are typically used to measure large-scale features such as the shape and size of the earth, or the location of large geographic features such as mountains and rivers. However, they are less effective at providing detailed information on smaller features such as buildings or urban infrastructure. This is because the resolution of geodetic surveys is limited, and they cannot capture the fine details that are necessary for many applications.

In conclusion, while geodetic surveys are a valuable tool for many applications, they are not without their drawbacks. They can be time-consuming, expensive, and limited in their scope and accuracy. As such, it is important to consider alternative approaches, such as remote sensing and GIS, which can provide complementary data and overcome some of the limitations of geodetic surveys.
