Differences and Similarities Between Topography and Geodesy

Posted on by admin-Gabriel
topography survey company

Topography and geodesy are sister disciplines that provide us with advanced knowledge of the surfaces in a given area.

Topography studies relatively small surfaces where precision is required for the construction of industrial plants, factories, houses, hydroelectric plants, etc. Geodesy, on the other hand, carries out these studies over much larger areas, such as the extension of a highway spanning hundreds of kilometers, the laying of a railway line connecting several cities, international airports, electrical grid systems, and more.

As we can see, the purpose of both studies is quite similar, but the scales are fundamentally different. For this reason, each uses distinct techniques and instruments.

Below is a list of the main differences between geodesy and topography:

Aspect Topography Geodesy
Scope and Scale Focuses on small, local areas like construction sites. Covers large areas, including continents and the entire planet.
Earth’s Curvature Not considered in small projects. Considers Earth’s curvature over long distances.
Instruments Total stations, optical levels, drones. GPS, GNSS systems, satellites.
Method Measures distances, angles, and elevations in local areas. Establishes global coordinates and studies Earth’s shape.
Applications Construction projects, land surveying, urban planning. Tectonic studies, global positioning systems (GPS).
Time Scale Used for short-term, specific projects. Used for long-term studies, including geological changes.
Coordinate Systems Uses local coordinate systems for precise locations. Uses global coordinate systems (e.g., WGS84).
Precision High precision in small areas. Precision adjusted for large-scale and global phenomena.

Differences Between Topographic Levels and Types of Leveling

Posted on by admin-Gabriel
realizando un levantamiento topografico

Among our clients, we’ve noticed an interest in clarifying the differences between topographic levels (tools) and leveling methodologies (procedures).

Types of Topographic Levels

In the field of topography, using different types of levels is essential for ensuring accuracy in height and distance measurements. Each type of level has its own purpose and characteristics, and its selection depends on the specific needs of the project.

Plane Levels
Plane levels, also known as optical levels, are primarily used to measure the horizontality of a terrain. This type of level requires the operator to manually adjust the instrument to make it horizontal before taking readings. They are ideal for simple leveling projects where it’s necessary to ensure that a surface is level in relation to a horizontal plane. They are widely used in construction and landscaping projects where ensuring the land or structural elements are perfectly level is necessary.

Line Levels
Line levels are more precise instruments that project a horizontal line on the ground, facilitating the alignment of structures across a surface. Unlike plane levels, they don’t require constant adjustments, making them faster and more efficient in repetitive alignment tasks. They are used in infrastructure projects, such as the installation of pipes or the alignment of pillars, where precision in height and alignment is crucial.

Automatic Levels
Automatic levels, also known as self-leveling levels, are the most advanced. They use a compensator that automatically adjusts the instrument to achieve perfect horizontality, eliminating human errors. They are extremely precise and are used in large-scale projects where accuracy is vital. This type of level is very common in civil engineering projects, road construction, and high-precision topographic surveys.

Types of Leveling

Leveling, the process by which the height difference between points on the ground is determined, can be carried out in various ways.

Trigonometric Leveling
Trigonometric leveling is based on trigonometric calculations using angles of elevation or depression and horizontal distances to determine the height of one point relative to another. This method is useful in rugged terrain or when the distances between points are long. It is employed in projects that require measuring height differences in uneven terrain or mountainous areas.

Height Leveling
Also known as geometric leveling, this is the most common method in topography. It consists of the direct measurement of height differences between several points using instruments like the automatic level. It is the most precise method and is used when high accuracy is required. It’s ideal for building construction, roads, and infrastructure projects that require precise height data.

Barometric Leveling
This type of leveling uses atmospheric pressure to estimate the altitude of different points. While it is less accurate than other methods, it is useful for preliminary studies in large areas. It is used in extensive topographic studies where millimetric precision is not required, such as in geographic explorations or environmental surveys.

Simple Leveling
Simple leveling involves measuring the height difference between two points using a handheld level or basic instrument. It is suitable for small projects where it is necessary to quickly determine the slope of the terrain. It is used in the construction of small lots, post installation, or landscaping projects.

Is a Topographic Survey Necessary for Building Construction?

Posted on by admin-Gabriel
levantamiento topografico para construcción de edificios

The answer to this question is YES.

A topographic survey is an essential study for the construction of any building, regardless of its size or location. This study provides architects and engineers with an accurate and detailed view of the area. Through a topographic survey, it is possible to plan actions related to the project, such as earthworks and foundation design. Additionally, a topographic survey can influence the design and construction of the structure. Even in areas that appear flat at first glance, a topographic survey is crucial to ensure that the building’s foundations are correctly placed, preventing future structural issues.

Why Should I Conduct a Topographic Survey in an Apparently Flat Area?

A terrain that seems flat to the naked eye may conceal various irregularities, such as slopes, changes in soil type, or even the presence of underground water bodies. A professional topographic survey helps identify these and other factors, ensuring that the building’s design adapts perfectly to the natural characteristics of the land. Moreover, it ensures proper drainage and soil stability, minimizing the risks of settlements or landslides that could compromise the building’s integrity.

Risks of Constructing a Building Without a Topographic Survey

Building without an adequate topographic survey can lead to a series of serious problems, including:

  • Unevenly settled foundations
  • Inadequate drainage leading to soil erosion issues
  • Errors in the alignment of the building
  • Additional costs due to unforeseen construction errors
  • Environmental impact

What Type of Topography is Recommended for Building Construction?

For the construction of a building, several types of topographic studies are recommended, such as:

  • Topographic survey with planimetry and altimetry
  • Geodetic survey
  • Survey with LIDAR or photogrammetry
  • Soil study

In summary, a topographic survey is a 100% necessary study for any type of construction. It is also advisable to conduct progressive topographic surveys as the construction progresses to avoid errors.

What Are the Marks Drawn During a Topographic Survey For?

Posted on by admin-Gabriel
puntos de levantamiento topografico

As you already know, topographic studies are of great utility to the construction and architecture industry as they provide the basic initial information necessary to undertake any construction or engineering work. With this in mind, it is important to consider that any project must have a serious topographic study before laying the first stone or even before creating a plan.

The Importance of a Topographic Survey Before Architectural Plans

The discipline of architecture involves the projection of elegant and beautiful constructions, but more than that, it consists of creating practical, useful, durable, and functional buildings.

Topography supports architects by providing the most relevant information so these professionals can develop their plans as adequately as possible. Consider, for example, the slope of the land and its importance for the design of sanitary installations. If the topographic plan does not provide this information to the architect, they will not be able to correctly locate bathrooms, drains, cisterns, etc. In this case, the lack of a topographic survey could lead to a series of problems resulting from an improvised plan.

Another paradigm is land with a diagonal slope. In this case, the architectural plan must consider not only the calculations for the front slope but also for the lateral slope, which will be necessary for the execution phase to make the necessary projections in earth movements, material acquisition, and other activities prior to construction.

Purpose of the Marks Made During a Topographic Survey

Now, let’s return to the topic of this article: the importance and purpose of the marks drawn on the ground during a topographic survey. These are reference points that serve both architects and engineers in developing their design and construction plans. These marks can be made from various materials such as wooden stakes, nails, tapes, paint, or chalk on the ground. It is important that they are made with visible and durable materials that allow surveyors and other construction professionals to identify these guide points.

What Relationship Do the Marks Have With Plans and Construction?

They have a direct relationship. The data collected and marked on the site is transferred to detailed plans that faithfully represent the terrain and its characteristics. These plans are essential for architects, engineers, and builders to have an accurate representation and location of the site on which the construction work will begin.

In the construction process, the marks allow workers to know exactly where to place foundations, structures, and reinforcements; they facilitate the alignment and leveling of the constructions and ensure that everything is built according to the design specifications. In other words, it is important to have them to guarantee that structures are built accurately and safely.

Types of Leveling in Surveying

Posted on by admin-Gabriel
servicio topografico de nivelacion geométrica

Leveling is an essential technique in topographyc surveying, as it allows for the precise determination of the relative height between specific points on a given plot of land. This practice is key in the planning and execution of engineering, construction, and cartographic projects, as it provides crucial information about the terrain’s relief. This, in turn, facilitates the design of structures that adapt to the site conditions and optimizes the calculation of necessary earthworks.

Additionally, understanding the slopes of the terrain is fundamental for the architectural development of a project. This knowledge enables the proper design of vital infrastructure, such as sanitary systems, which rely on a minimum slope to ensure the correct flow and evacuation of fluids. In areas with steep inclines, the topographic data obtained through leveling is indispensable for determining whether cut and fill operations are required or if stepped constructions will be used to take advantage of the natural topographic features.

Below, we will explore the different types of leveling used in surveying, each with its characteristics and applications:

Geometric Leveling

Also known as differential leveling, it is one of the most precise and commonly used methods in surveying. This method is based on the use of an optical or automatic level and a leveling rod to measure the difference in height between two points. It is carried out by establishing a horizontal line of sight and reading the elevations at different points.

It is commonly used for:

  • Civil engineering and construction projects
  • Road and railway construction
  • Installation of public utilities

Trigonometric Leveling

This method is based on the use of angles and distances measured with a theodolite. It involves measuring vertical and horizontal angles along with the distance between points of interest to calculate the height difference using trigonometric formulas. This method is especially useful in rugged terrains where geometric leveling can be difficult to implement.

This method is suitable for:

  • Mapping mountainous terrains
  • Geological and mining studies
  • Installation of telecommunications towers and power lines

Barometric Leveling

This method uses atmospheric pressure to determine the elevation of different points. It employs barometers or altimeters to measure air pressure at various locations and then calculates the height difference based on pressure variations. Although less precise than other methods, it is useful for preliminary surveys and in extensive areas where other methods would be impractical. It is commonly used in:

  • Geographic explorations
  • Environmental studies
  • Topographic surveys in remote areas

GPS Leveling

This method uses satellites to determine the elevation of specific points relative to sea level. It employs GPS receivers to capture signals from multiple satellites and calculate the height using complex algorithms. GPS leveling is increasingly popular due to its high precision and ability to cover large areas quickly.

It is optimal for:

  • Digital mapping
  • Topographic surveys in large infrastructure projects
  • Monitoring and managing natural resources

Hydrostatic Leveling

This method uses the principle of communicating vessels to determine height differences. It involves using a tube filled with liquid (usually water) that connects two points. The height of the liquid at both ends of the tube is measured to calculate the height difference between the points. It is a simple and effective technique for short distances and in areas where other methods are impractical. It is especially useful for indoor installations, leveling buildings and structures, and adjusting machinery and equipment, where the simplicity and economy of the method are significant advantages.

In conclusion, the choice of leveling method in surveying depends on several factors, including the required precision, terrain characteristics, the extent of the area to be covered, and available resources. Each method has its own advantages and applications, so it is essential to consult with specialists to determine the most appropriate method for each case.

Why We Recommend Our Drone Topography Service

Posted on by admin-Gabriel
benefits of drone topography

The discipline of topography is constantly evolving; however, it is in recent years with the emergence of drones that this important branch of engineering is undergoing significant changes in the way topographic data is collected and recorded.

In this article, we will explore the advantages of drone topography and compare it with traditional methods.

Speed

Drones equipped with LiDAR (Light Detection and Ranging) sensors and high-resolution cameras can collect topographic data at a much faster and more efficient rate than traditional surveying services. Additionally, the results of a topographic survey conducted using these means are highly accurate.

In road construction projects, where a traditional surveying team might take weeks, drones equipped with LiDAR can complete the work in just a few days, allowing engineers to start the design and architecture phase much more quickly.

Precision

Drone topography is precise and detailed thanks to high-definition sensors and cameras. These data are processed using software such as photogrammetry software, which creates accurate three-dimensional models of the terrain.

An example of the precision and reliability of drones is that, thanks to their multispectral cameras, they can even detect areas with higher or lower humidity to provide maximum information to the project engineers.

Safety

Drone topography allows us to access remote areas, rocky slopes, or areas with dangerous cliffs while maintaining the safety of the human team and allowing us to collect data in difficult or inaccessible terrain.

An example of this is found in the mining industry, where drones fly over dangerous areas, such as steep slopes or recent excavation areas, to conduct detailed inspections without endangering the safety of personnel.
